You just bought a cordless drill or inherited one from a relative, and it came with exactly three bits—none of which are the right size for the shelf brackets you’re trying to mount right now. Every hardware store aisle has 47 different drill bit sets, half of them claiming to be “complete,” and you’re standing there wondering if you need titanium-coated, carbide-tipped, or just the $12 plastic case with a hundred mystery bits.
Here’s what actually happens: most beginners use about eight types of accessories in their first year of home repair, and the rest sit untouched in a bin. I’ve mounted shelves, assembled furniture, patched drywall, and replaced outlets in two different homes—one rented, one owned—and the drill bits I reach for are the same five or six every time.
Verdict: Skip the 500-piece sets. A good 20-50 piece starter kit covering twist bits, spade bits, and screwdriver bits ($30-50) plus a masonry bit pack ($8-12) will handle 95% of beginner DIY projects for the next year. Add attachments like a flexible shaft or right-angle adapter only when a specific project needs them.

Drill bit materials: what you’re actually paying for
Before you pick a bit set, you need to understand what separates a $5 pack from a $50 pack. It’s not just marketing—the metal matters.
High-speed steel (HSS) is the baseline material for most twist bits. It’s hard enough to cut wood, soft metals, and plastic without dulling instantly. A basic HSS bit set will handle typical homeowner tasks for a year or two of occasional use. When you see an unmarked budget bit set, it’s almost always plain HSS.
Titanium-coated HSS is the same steel core with a thin titanium nitride coating. The coating reduces friction, keeps the bit cooler while drilling, and extends lifespan by about 3x compared to plain HSS. You’ll see these marketed as gold-colored bits. They cost about 50% more than plain HSS and they’re worth it if you drill frequently—the coating prevents the tip from dulling as fast. For occasional use, the premium isn’t necessary.
Cobalt steel adds cobalt to the steel alloy (not a coating). These bits stay sharp longer and handle harder metals like stainless steel. They’re overkill for wood and plastic, and they cost 2-3x more than HSS. Skip them unless you’re drilling metal regularly.
Carbide-tipped bits have a brazed carbide tip—carbide is much harder than steel and survives abrasive materials like masonry, tile, and concrete. You’ll see carbide tips on masonry bits and spade bits designed for composite materials. They cost more but they last 10x longer when used on the right material. Don’t use carbide bits on soft materials—they’re brittle and can chip if they catch or bind.
What to buy: For a beginner, titanium-coated HSS twist bits are the sweet spot—durable enough to justify the cost, not so expensive you’ll hesitate to use them. Save plain HSS for disposable sizes (tiny pilot bits you’ll lose or break) and reserve carbide for masonry work.
Chuck compatibility: making sure bits fit your drill
Most frustration with new drill bits comes from size mismatches. Your drill’s chuck—the part that grips the bit—has a maximum capacity, and not every bit fits every drill.
Keyed chucks require a toothed key to tighten. They grip more securely and handle higher torque, but swapping bits takes longer. If your drill came with a small metal key, you have a keyed chuck.
Keyless chucks tighten by hand. They’re faster to swap but can slip under heavy torque—especially with spade bits in hardwood. Most cordless drills sold in the last five years use keyless chucks.
Quick-change chucks accept hex-shank bits directly—no twisting, just push and pull. Some newer drills have quick-change chucks built in; others require an adapter sleeve. If your drill has a quick-change system, make sure your bit sets include hex-shank bits or buy a quick-change adapter for round-shank bits ($8-12).
Chuck capacity is the maximum bit diameter your drill can hold. Most homeowner drills have a 3/8-inch or 1/2-inch chuck. If you buy a spade bit with a 1/2-inch shank and your drill maxes out at 3/8-inch, it won’t fit. Check your drill’s manual or look for capacity markings on the chuck itself before buying large bits.
When in doubt, hex-shank bits are the safest bet—they fit keyed, keyless, and quick-change systems equally well.
Drill bit types explained (the ones beginners actually use)
If you’ve never bought drill bits before, the categories sound like a foreign language. Here’s what each type does and when you’ll reach for it.
Twist bits (your workhorse)
These are the spiral-shaped bits you picture when someone says “drill bit.” They work on wood, metal, plastic, and soft materials. About 80% of beginner projects use twist bits—pilot holes for screws, clearance holes for bolts, small holes for wire routing.
I keep a set from 1/16-inch up to 1/2-inch. The ones I use most: 1/8-inch for pilot holes in wood, 3/16-inch for drywall anchors, and 1/4-inch for furniture assembly. These wear out faster than specialty bits because you use them constantly, so don’t cheap out on the smallest sizes.
Common use: Hanging pictures, assembling IKEA furniture, installing cabinet hardware, running cables through studs.
Spade bits (fast, rough holes in wood)
Spade bits look like flat paddles with a center point. They cut large holes in wood quickly—1/2-inch to 1-1/2-inch is the typical range. You’ll use these for running electrical cable through studs, drilling clearance holes for door hardware, or making space for plumbing pipes.
They’re aggressive and fast, which is great when you need a 1-inch hole in a 2x4. The downside: they splinter the wood on the exit side unless you back the piece with scrap or stop just before breakthrough and finish from the other side. I learned that the hard way installing a deadbolt—splintered the edge of the door frame and had to fill it with wood putty.
Safety note on spade bits: Spade bits generate high torque and they can bind suddenly if they hit a knot or the wood pinches the blade. When that happens, the drill twists hard in your hands—sometimes hard enough to sprain a wrist if you’re not braced. OSHA notes that maintaining firm control and anticipating tool reaction is critical with high-torque bits. Use both hands, keep your stance wide and stable, and start at low speed until the bit bites in. If the bit binds, release the trigger immediately—don’t try to power through it.
Common use: Door hardware installation, routing cables behind walls, creating access holes for pipes or wires.
Brad-point bits (cleaner holes in wood)
Brad-point bits look like twist bits with a sharp center spike. That spike keeps the bit from wandering, so you get a precise hole with minimal splintering. They’re slower than spade bits but leave a much cleaner edge.
I didn’t own these until my second year of DIY work, when I started building shelves instead of just hanging them. If you’re working on furniture, cabinetry, or anything where the hole will be visible, brad-point bits are worth it. For rough framing or hidden holes, stick with twist or spade bits.
Common use: Furniture building, dowel joinery, visible holes in finished wood.
Masonry bits (concrete, brick, tile)
Masonry bits have carbide tips—harder than steel—and they’re designed to drill into concrete, brick, cinder block, and tile. You need these if you’re mounting anything to a concrete or brick wall: shelves, TV brackets, handrails, outdoor lights.
Standard twist bits will overheat and dull instantly on masonry. I tried it once on a basement wall, ruined a perfectly good 3/16-inch bit, and bought a masonry set the same day.
For small holes (under 1/4-inch), a regular drill works fine—apply steady pressure and let the bit do the work. For larger holes or hard concrete, you’ll want a hammer drill, which adds a percussive action that pulverizes the masonry while the bit rotates. Most beginners can get by with masonry bits in a standard drill for anchor holes, but if you’re drilling more than four or five holes in concrete, the hammer function saves your arms and your bits. This Old House recommends using hammer drills for any masonry work beyond small pilot holes, and I agree—I borrowed one for a concrete wall project and bought my own a month later.
Safety note on masonry bits: Concrete and brick generate abrasive dust that gets everywhere. Wear safety glasses and a dust mask—concrete dust is hard on your lungs over time. Masonry bits also heat up faster than wood bits, so let them cool before touching the tip.
Common use: Wall anchors in concrete or brick, mounting outdoor fixtures, installing shelving on masonry walls.
Forstner bits (large, flat-bottomed holes—advanced)
Forstner bits cut wide, clean, flat-bottomed holes in wood. They’re beautiful tools and they’re expensive. Unless you’re doing cabinetry, concealed hinges, or recessed hardware, you don’t need them in year one.
I mention them because they show up in a lot of “complete” drill bit sets, and beginners see them and wonder what they’re for. The answer: very specific woodworking tasks. You’ll know when you need one because a spade bit won’t cut it (literally—wrong shape). Until then, skip them.
Power drill bits sets: buy a kit or build one yourself?
Here’s the trade-off: a good 20-50 piece set gives you variety without redundancy. A 100+ piece set gives you a lot of duplicates (do you really need six 1/4-inch bits?) and a plastic case that cracks in two years. A curated individual purchase gives you exactly what you need but costs more up front.
For beginners, I recommend starting with a mid-size set and adding specialty bits as projects demand them.
Starter set tier ($30-50)
Dewalt DWA1169 (50-piece): Includes twist bits, spade bits, screwdriver bits, and a decent storage case. This is the set I’d buy if I were starting over. It covers wood, metal, and plastic, and the bits hold up to regular homeowner use. About $35 at Home Depot as of June 2026.
Bosch 31-piece Core Bit Set: Smaller but higher quality. Includes the most-used twist bits, a few spade bits, and driver bits. Better steel than the Dewalt, but you’ll need to add masonry bits separately. Around $30.
What you can do with this tier: Hang shelves, assemble furniture, install cabinet hardware, drill pilot holes, mount curtain rods, run small cables through framing.
Mid-tier set ($50-100)
Makita D-36980 (68-piece): Includes brad-point bits and masonry bits in addition to the basics. Good case with labeled slots. I’ve used this set for two years and haven’t broken a bit yet—unusual for me. About $65.
Dewalt DWA2T40IR (40-piece impact-rated set): Tougher bits rated for impact drivers, but they work fine in a standard drill too. Includes screwdriver bits designed not to cam out (strip the screw head). Around $55.
What you can do with this tier: Everything in the starter tier, plus masonry anchors, cleaner holes in finished wood, and screwdriving without stripping heads.
Build-it-yourself option
If you’d rather pick exactly what you need:
- Twist bit set (1/16” to 1/2”): $12-18 for a 13-piece Dewalt or Bosch set
- Spade bit set (1/2” to 1-1/2”): $10-15 for a 6-piece set
- Masonry bit set (1/8” to 1/2”): $8-12 for a 5-piece set
- Screwdriver bit set (Phillips, flathead, square): $10-15 for a 20-piece set
- Storage case: $8-12 for a bit organizer
Total: $50-70, and you’ve chosen every piece. The downside: it takes more time and you don’t get the “grab and go” convenience of a single kit.
Power drill attachments beyond bits
Drill bits get the attention, but attachments can turn your drill into different tools entirely—when you need them.
Screwdriver bit sets (essential from day one)
If you assemble furniture, install hardware, or do any kind of fastening work, you need a set of screwdriver bits. Phillips (#1, #2, #3), flathead, and square drive (Robertson) cover most screws you’ll encounter.
I keep a magnetic bit holder in my drill and swap bits constantly. It’s faster than a manual screwdriver and way less tiring on your wrist. Get an impact-rated set if you can—they last longer and don’t cam out as easily.
Use case: Furniture assembly, cabinet installation, door hardware, electrical cover plates, appliance repair.
Hex shank adapters (useful when sizes don’t match)
Some bits have round shanks, some have hex shanks, and sometimes your drill chuck doesn’t grip the bit you need. A hex shank adapter fixes this. They’re cheap ($5-8), small, and I’ve used mine exactly twice in three years—but both times I needed it right then.
Not essential for year one unless you’re mixing old and new bit sets.
Flexible shaft extension (tight spaces)
A flexible shaft is a 12-18 inch cable that attaches to your drill on one end and holds a bit on the other. It lets you reach into tight corners, behind appliances, under sinks, or inside cabinets where the drill body won’t fit.
I didn’t own one until I had to drill a hole behind a washing machine to run a drain line. The drill wouldn’t fit in the gap. The flexible shaft did. Cost about $15, saved me from moving a 200-pound appliance.
Use case: Drilling in confined spaces, behind appliances, inside cabinets, under stairs.
Right-angle drill attachment (corners and edges)
A right-angle head turns your drill 90 degrees, so you can drill parallel to a wall or into a corner where the drill body won’t fit. It’s a niche tool—I’ve used mine four times in two years—but when you need it, nothing else works.
These run $20-40 depending on brand. If you’re doing a lot of framing work or cabinet installation, it’s worth it. Otherwise, wait until a project demands it.
Use case: Drilling into studs from inside a wall cavity, tight corner work, framing between joists.
Drill brush and wire wheel (cleaning and surface prep)
A drill brush attachment is exactly what it sounds like: a scrub brush that spins. Wire wheels are the same idea but with metal bristles. They’re great for cleaning rust off tools, scrubbing grout, prepping surfaces for adhesive, and paint stripping—though if the paint is from a pre-1978 building, test for lead first (EPA.gov/lead).
Safety note: Wire wheels throw debris and can catch loose clothing or gloves. Wear safety glasses, keep your hands clear of the spinning bristles, and don’t use one if the wire tips are bent or broken—they’ll snap off and fly at you. I use these sparingly and carefully.
Use case: Rust removal, grout cleaning, paint stripping, surface prep for bonding or painting.
What NOT to buy in year one
- Hole saws: Expensive, single-purpose, and you’ll need maybe two sizes for door hardware. Buy when you have a specific project.
- Grinder or sanding attachments: These turn your drill into a grinder or sander, but they’re slower and less safe than the actual tool. Skip them.
- Polishing or buffing pads: For cars or metalwork—not typical beginner DIY.
- Hammer drill bits (if you don’t have a hammer drill): They require a hammer function on the drill. Regular masonry bits work fine for small holes.
Common beginner mistakes (I’ve made most of these)
Buying a giant set and never using half of it
A 200-piece set sounds like value, but 150 of those bits are duplicates or sizes you’ll never need. You end up with a heavy case, a cluttered toolbox, and bits you can’t identify. Start small, add what you need.
Not using pilot holes
A pilot hole is a small hole you drill before driving a screw. It prevents wood from splitting, keeps screws straight, and makes driving easier. I skipped pilot holes on my first bookshelf build and split three boards. Now I drill a 1/8-inch pilot hole before every screw in hardwood or near an edge.
Using dull bits
A dull bit overheats, smokes, burns the wood, and eventually snaps. If you’re pushing hard and the bit isn’t cutting, stop. Sharpen it (if you know how) or replace it. Twist bits under $2 aren’t worth sharpening—just swap them.
Confusing a drill with an impact driver
An impact driver looks similar to a drill but delivers rotational impacts—great for driving screws, terrible for drilling precise holes. If you’re buying bits for an impact driver, make sure they’re impact-rated. Regular bits can shatter under the hammering force.
Ignoring chuck capacity
Most cordless drills have a 3/8-inch or 1/2-inch chuck (the part that holds the bit). If your bit shank is larger than your chuck, it won’t fit. Check your drill’s chuck size before buying large spade bits or specialty bits.
Skipping the two-hand grip on spade and masonry bits
Twist bits are forgiving—you can one-hand them on light work. Spade bits and masonry bits are not. Spade bits bind suddenly and twist the drill hard when they catch. Masonry bits require sustained pressure that’ll fatigue one arm fast. Use both hands: one on the trigger handle, one supporting the body of the drill. Brace your feet and expect the drill to push back. DeWALT’s safety manuals specify two-handed operation for bits over 1/2-inch and I’ve learned that lesson the hard way—once with a sprained thumb.
Beginner safety and maintenance
Before you drill
- Secure the workpiece. Clamp it down or hold it firmly. A spinning bit can grab and fling a loose piece of wood.
- Wear safety glasses. Wood chips, metal shavings, and masonry dust fly everywhere. I’ve taken a splinter to the cheek—glasses would’ve saved me.
- Tie back long hair, remove jewelry. Anything loose near a spinning tool is a risk.
- Check bit tightness. A loose bit wobbles, drills crooked holes, and can fly out of the chuck. Tighten the chuck by hand, then give it one firm twist with the chuck key (or hand-tighten if it’s keyless).
- Know what’s behind the wall. Before drilling into walls, check for electrical wiring and plumbing. Use a stud finder with wire detection, or assume wires run vertically from outlets and switches. Drill into a live wire and you’ll trip a breaker at best, get shocked at worst.
After you drill
- Let the bit cool. Metal-on-metal or fast drilling heats bits to the point where they’ll burn your skin. Give them a minute.
- Clean and store bits. Wipe off sawdust, metal shavings, or masonry dust. Store bits in a case or organizer to prevent rust and damage.
- Inspect for damage. Bent bits drill crooked holes. Chipped bits can shatter. Toss them.
When a bit is too dangerous to use
If a bit is bent, cracked, has missing teeth (on a hole saw), or the tip is broken off, throw it away. A damaged bit can catch, snap, or send shrapnel flying. They’re cheap enough that the risk isn’t worth it.
Budget tiers: what you can build at each level
Under $50: Assemble furniture, hang shelves on studs, install cabinet hardware, drill pilot holes, mount curtain rods, hang pictures. Basically all the common household tasks that don’t involve masonry or specialty woodworking.
$50-100: Add masonry work (TV mounts, shelves on concrete walls), cleaner holes in visible wood (furniture building), and better screwdriving bits that won’t strip. You’re equipped for most weekend DIY projects.
$100-150: Add attachments (flexible shaft, right-angle head, brush wheels), specialty bits (brad-point, countersink), and a better storage system. You’re building things, not just assembling or mounting them.
I started at the $40 level with a Dewalt set from Home Depot and added a masonry bit pack two weeks later when I realized I couldn’t drill into my basement wall. A year later, I added a flexible shaft and a right-angle head for a cabinet install. Build your kit as your projects demand—don’t front-load it.
FAQ
What drill bits do I need as a beginner?
Start with a 20-50 piece set that includes twist bits (1/16” to 1/2”), a few spade bits (1/2” to 1-1/2”), and screwdriver bits (Phillips #1, #2, and flathead). Add a masonry bit set (1/8” to 1/4”) if you’re mounting anything to concrete or brick walls. That covers 90% of beginner projects.
Can I use one drill bit for everything?
No. Twist bits work on wood, metal, and plastic, but they’ll dull instantly on masonry. Spade bits work on wood but not metal. Masonry bits work on concrete and brick but not wood. Each material needs a bit designed for it. Using the wrong bit damages the bit, the material, or both.
Should I buy a drill bit set or individual bits?
For beginners, a mid-size set (20-50 pieces) is more cost-effective than buying individual bits. You get the variety you need without paying $3-5 per bit. Once you know which sizes you use most, buy higher-quality replacements for those individually.
What’s the difference between titanium-coated and plain HSS bits?
Titanium-coated bits have a thin coating that reduces friction and heat, making them last about three times longer than plain high-speed steel (HSS) bits. They cost about 50% more. For occasional use, plain HSS is fine. If you drill often, titanium coating pays for itself in longer bit life.
What’s the difference between impact-rated bits and regular bits?
Impact-rated bits are designed to handle the hammering force of an impact driver. They’re made from tougher steel and less likely to shatter under impact. You can use them in a regular drill, but you can’t safely use regular bits in an impact driver—they may crack or snap.
How do I know when to replace a drill bit?
If the bit is visibly damaged (bent, chipped, broken tip), replace it immediately. If it’s dull—meaning it burns the wood, smokes, or requires a lot of pressure to cut—sharpen it (for larger bits) or replace it (for small twist bits under $2). A sharp bit cuts easily with light pressure.
Do I need a hammer drill for masonry bits?
For small anchor holes (under 1/4-inch) in brick or concrete, a standard drill with masonry bits works fine. For larger holes, harder concrete, or more than a few holes, a hammer drill makes the job faster and easier. The percussive action pulverizes the masonry while the bit rotates, saving your arms and extending bit life.

You don’t need a 500-piece set to start drilling holes and driving screws. Get a solid 50-piece starter kit with titanium-coated twist bits if your budget allows, add masonry bits when you hit concrete, and pick up specialty bits as projects require them. The drill you already own plus $50 in accessories will handle a year’s worth of weekend DIY work—shelves, furniture, picture hanging, outlet covers, and everything in between. Once you’ve actually used the basics for six months, you’ll know exactly what else you need. For more on choosing the drill itself, see best cordless drills for beginners .
