Our Review Criteria: Bit material governs everything else, because a bit wrong for the surface fails no matter how well it is made. We matched high-carbon steel, HSS, cobalt (M35 and M42), carbide, and diamond to the materials each is built to cut, then compared point geometry (a 118-degree point centers in wood, a 135-degree split point self-centers on metal), flute design and chip clearance, shank fit across round, hex, and SDS-Plus chucks, and coatings such as black oxide and titanium nitride. We read manufacturer specifications against independent and owner reviews to surface weaknesses a spec sheet hides, such as brittleness in cobalt bits or coatings that wear at the tip. We check every set for availability and swap it when discontinued.
The drill supplies the spin, but the bit does the cutting. Hang a picture, build a deck, or punch a hole in concrete, and it is the small piece of steel at the end doing the real work.
Grab the wrong one and you dull the edge, wander off your mark, or snap the bit mid-hole. Two things decide the match: the bit’s material, which sets how hard a surface it can cut, and its point geometry, which sets how cleanly it starts. Get both right and the hole almost drills itself.
We broke down ten of the best drill bit sets on the market, from a general-purpose titanium kit to specialists for concrete, hardened steel, and glass. Each pick is judged on material, point and flute design, size range, and the job it is actually built for.
Are Drill Bits Interchangeable?
For the most part, yes. Modern drills usually feature a universal three-jaw chuck. Most drills easily grip round and hexagonal shanks, which are the industry standards.
However, there are exceptions. Rotary hammer drills often use SDS chucks (Slotted Drive System), which require specialized bits with grooves in the shank. Impact drivers strictly use 1/4-inch hex shanks. Always check your tool’s chuck type before buying a new set.
How to Choose the Best Drill Bit
Every bit serves a purpose. You wouldn’t use a wood spade bit on concrete, and you shouldn’t use a masonry bit on sheet metal. Here is what you need to know before you buy.
Who Makes the Best Drill Bits?
While generic bits exist, sticking to reputable brands usually guarantees better steel quality and quality control.
Product Reviews
We compared sets that hold up across wood, metal, masonry, and glass, scoring each on material, point and flute geometry, size range, and the job it is built for. From a do-everything general kit to specialists for stainless steel or tile, here are our ten picks.
DeWALT Titanium 14-Piece Drill Bit Set
Best Titanium-Coated Drill Bits
DeWALT consistently delivers reliable accessories, and this 14-piece titanium-coated set is our top pick for general use. These bits handle both wood and metal with ease, making them perfect for the average homeowner’s toolbox.
The standout feature is the “Pilot Point” tip. It starts drilling on contact, preventing the bit from walking across your material. This clean start means you rarely need to use a center punch.
The sizes run from 1/16-inch to 1/2-inch. We also appreciate the “no-spin” shanks on the larger bits; they have flat sides ground onto the shaft so the chuck can grip them tightly without slipping. DeWALT claims the titanium coating extends the life of these bits two times beyond standard options.
Pros
- Versatile: 14-piece set covers most common tasks.
- Durable: Titanium coating resists heat.
- Grip: No-spin shanks prevent slipping in the chuck.
- Value: Professional features at a DIY price.
Cons
- Origin: Manufactured in China.

DeWALT 21-Piece Titanium Drill Bit Set
Best Drill Bits for a Drill Press
When you are setting up a drill press, you want a wide range of sizes readily available. This DeWALT 21-piece kit offers granular size options from 1/16-inch up to 1/2-inch, ensuring you always have the precise diameter for the job.
Like the smaller set, these feature the titanium coating for heat resistance and the Pilot Point tip. The tip design is excellent for drill presses because it self-centers, reducing the need for clamping and center punching on softer materials.
The tough plastic case keeps everything organized, which is essential in a busy shop environment. The titanium coating should outlast black oxide bits significantly, especially when used for repetitive drilling tasks.
Pros
- Precision: Pilot Point reduces walking.
- Long Life: Titanium coating fights heat buildup.
- Variety: 21 sizes cover almost any standard project.
- Organization: Includes a durable storage case.
Cons
- Origin: Made in China.

Drill America KFD29J 29-Piece HSS Drill Bit Set
Best Drill Bits for Wood and Metal
If you want one twist-bit set that moves between wood, softwood, and harder metals without swapping kits, this Drill America KFD29J set earns the spot. It is a contractor-grade workhorse rather than a specialist tool, which is exactly what most home shops actually reach for.
The set spreads 29 sizes from 1/16-inch to 1/2-inch in 1/64-inch increments, so you rarely have to round up or down to the wrong diameter. Each bit is high-speed steel finished with a black-and-gold oxide coating that resists rust and cuts friction on hard material.
The detail that sets it apart from a budget HSS set is the 135-degree split-point tip. It bites on contact and stops the bit from skating across sheet metal or a glazed knot, so you can skip the center punch on most starts. The bits resharpen on a bench grinder, which stretches the kit’s life well past a coated-only set.
Pros
- Range: 29 sizes in fine 1/64-inch steps.
- Accurate Starts: 135-degree split point resists walking.
- Versatile: Handles wood, plastic, and harder metals.
- Serviceable: HSS bits can be resharpened.
Cons
- Not for Stainless: Plain HSS struggles on hardened steel; step up to cobalt.
- Case: The round index can be awkward to reload one-handed.

Irwin 29-Piece M35 Cobalt Drill Bit Set
Best Drill Bits for Metal
Standard HSS bits burn up the moment they touch stainless steel or cast iron, which is why hard-metal work calls for cobalt. This Irwin set is built from M35 alloy, meaning roughly 5% cobalt is melted into the steel itself rather than coated on top. That heat tolerance is what lets the cutting edge survive the friction these metals throw off.
The 29-bit lineup runs from 1/16-inch to 1/2-inch in 1/64-inch increments, so it covers fine fabrication sizes most cobalt sets skip. Each bit uses a 135-degree split point that starts on contact, which matters even more on metal because a wandering bit ruins the workpiece.
Irwin builds these with a heavy-duty web for rigidity, and the three-cartridge index case keeps the sizes findable on a busy bench. The honest trade-off is the one every cobalt bit shares: the alloy is hard but brittle, so a side-load or a tilted drill can snap the thinner sizes. Run it slow with cutting fluid and keep the bit straight.
Pros
- Through-and-Through Cobalt: M35 alloy survives stainless and cast iron.
- Fine Coverage: 29 sizes in 1/64-inch steps.
- Accurate: 135-degree split point bites without walking.
- Serviceable: Solid cobalt resharpens without losing its grade.
Cons
- Brittle: Side pressure can snap the smaller bits.
- Technique: Needs slow speed and cutting fluid to last.

Makita 5-Piece SDS-Plus Drill Bit Set
Best Drill Bits for Concrete
If you own a rotary hammer drill, you need SDS-Plus bits. This Makita set is designed specifically for that purpose. The slotted shank locks into the drill, allowing it to hammer back and forth with massive force without slipping.
These are the bits you want for punching holes in concrete or brick. The tips feature tungsten carbide, which is hard enough to crush masonry and cut through rebar. Makita claims these tips last up to four times longer than standard masonry bits.
The set includes five essential sizes from 3/16-inch to 1/2-inch. The flute design effectively channels concrete dust out of the hole, which keeps the bit cooler and speeds up your work.
Pros
- Efficient: High-volume flutes clear dust quickly.
- Tough: Tungsten carbide tips handle reinforced concrete.
- Secure: SDS-Plus shank eliminates slipping.
- Focused: 5-piece set covers key masonry sizes.
Cons
- Compatibility: Only fits SDS-Plus rotary hammers.
- Limited Use: Not for wood or metal.

Irwin 35-Piece Screw Extractor/Drill Bit Set
Best Drill Bits for Automotive Use
Mechanics know the pain of a snapped bolt or a stripped screw head. This Irwin 35-piece set is a lifesaver for automotive work. It isn’t just a drill bit set; it’s a full extraction kit.
You get high-quality drill bits to bore into the damaged fastener, plus spiral screw extractors to grip and reverse it out. The included drill bits are cobalt alloy, meaning they can drill into hardened automotive bolts without dulling instantly.
The left-hand bits are particularly clever, often, the act of drilling into the bolt in reverse is enough to loosen it. Sizes range from tiny 5/64-inch bits for small fittings up to 1/2-inch for larger bolts.
Pros
- Material: Cobalt bits handle hardened steel.
- Function: specialized extractors for stripped screws.
- Design: Reverse spiral flutes help back out bolts.
- Comprehensive: 35-piece set covers most auto needs.
Cons
- Price: More expensive than standard sets.

DeWALT 7-Piece Masonry Drill Bit Set
Best Drill Bits for Masonry
This 7-piece set from DeWALT is a great companion for standard hammer drills (non-SDS). If you need to mount a TV bracket into brick or anchor a shelf into a concrete wall, this kit has you covered.
The sizes range from 3/16-inch to 1/2-inch. DeWALT uses a Rock Carbide tip designed to withstand the percussion impact of drilling into stone and concrete. The shanks have three flat sides, which is a massive plus; it prevents the bit from spinning inside the chuck under high torque.
The spiral flutes are engineered to pull dust out efficiently. While not as heavy-duty as SDS bits, these are perfect for DIY masonry jobs around the house.
Pros
- Quality: Made in Germany.
- Tip: Rock carbide handles concrete and stone.
- Grip: Flat shanks eliminate chuck slip.
- Value: Affordable masonry solution.
Cons
- Durability: Not intended for industrial rotary hammers.
- Fragile: Carbide is brittle; avoid bending forces.

DeWALT 21-Piece Black Oxide Drill Bit Set
Best Black Oxide Drill Bits
Black oxide is the coating most pros default to for general drilling, and this DeWALT 21-piece set shows why. The conversion coating holds lubricant and shrugs off rust, so the bits keep cutting cleanly in wood, hardwood, PVC, fiberglass, and mild steel without the price jump of titanium or cobalt.
The sizes span 1/16-inch to 1/2-inch, with a few of the most-used small diameters doubled up so the first bit you snap doesn’t end the job. A 135-degree split point starts the hole on contact and keeps the bit from walking on metal.
What lifts this above a basic black-oxide kit is the parabolic flute paired with a 31-degree helix. The wide flute clears chips fast in deep holes, while the reduced helix angle tames the aggressiveness that makes true parabolic bits grab. It is a sensible all-rounder for someone who wants durable, sharpenable bits without overpaying.
Pros
- Corrosion Resistance: Black oxide holds lubricant and fights rust.
- Chip Clearing: Parabolic flutes eject debris from deep holes.
- Accurate Starts: 135-degree split point reduces walking.
- Practical Sizes: Common diameters doubled for breakage.
Cons
- Mild Metal Only: Coating offers no edge on stainless or cast iron.
- Coating Wears: The oxide layer fades with heavy use and sharpening.

COMOWARE 16-Piece Titanium Drill Bit Set
Best Drill Bits for PVC
Not every job needs industrial steel. For curtain rods, PVC pipe, and the steady stream of small holes a household generates, this COMOWARE set is the budget pick that does the work without overspending.
The bits are titanium-coated high-speed steel, so they slide through plastic, wood, and aluminum with low friction and shrug off the rust that kills cheap bare-steel bits in a damp garage. Sizes run from 1/16-inch to 1/4-inch, covering the light-duty range and nothing heavier.
The useful twist here is the 1/4-inch hex shank on every bit. That means they snap straight into an impact driver or a quick-change chuck, no adapter needed, which is handy if your everyday tool is a driver rather than a full drill. The two-flute geometry clears chips fast on soft material. Treat it as a starter or glovebox kit, not a metalworking set.
Pros
- Quick-Change: 1/4-inch hex shank fits impact drivers.
- Coated: Titanium finish resists corrosion and friction.
- Light-Duty Ready: Clean cuts in PVC, wood, and aluminum.
- Budget: An inexpensive starter kit for a first toolbox.
Cons
- Small Sizes Only: Tops out at 1/4-inch.
- Light Build: Not for stainless or repeated heavy metal drilling.

Bosch 8-Piece Glass and Tile Bit Set
Best Drill Bits for Tile
Drilling through tile is risky; one wrong move and the tile cracks. Bosch designed these carbide-tipped bits specifically to reduce that stress. They feature a spear-point design that grinds through the hard glaze of ceramic and glass without shattering it.
The set ranges from 1/8-inch to 3/4-inch. Bosch uses a three-sided flat shank to ensure the bit doesn’t slip in the chuck, which is critical when you need precise control on slippery surfaces.
These aren’t for hammer drills, use them on a low-speed rotary setting with water for cooling, and they will cut clean holes for bathroom fixtures and mirrors effortlessly.
Pros
- Precision: Diamond-ground carbide tip.
- Control: No-spin flat shanks.
- Safety: Designed to prevent tile cracking.
- Application: Ideal for glass, ceramic, and mirrors.
Cons
- Specialized: Useless on wood or metal.

How to Use Drill Bits
Installing a bit is easy, but doing it correctly prevents wobble and accidents. Here is the quick rundown.
1. Match the Bit to the Material
Identify your surface. Standard twist bits are great for wood and light metal. If you are hitting concrete, switch to a masonry bit. If you need a large hole in wood (like for a door lock), grab a spade bit or hole saw.
2. Check Your Chuck
Most modern drills have keyless chucks. Hold the drill grip and rotate the chuck collar counter-clockwise to open the jaws. If you have an older drill, you will need the chuck key to loosen it.
3. Insert and Center
Slide the bit shank into the jaws. Ensure it is centered between all three jaws, sometimes a small bit can slip into the gap between two jaws, which causes it to spin off-center.
4. Tighten It Down
Rotate the collar clockwise to hand-tighten. Once it grips the bit, give it a firm twist to lock it. If you are using a keyed chuck, insert the key into the side hole and turn clockwise until tight.
5. Set Your Speed
Drills usually have a speed switch (1 or 2). Use “1” (Low Speed/High Torque) for large bits and driving screws. Use “2” (High Speed) for small drill bits.
6. Drill Straight
Place the tip on your mark. Apply steady pressure directly in line with the bit. Don’t push too hard; let the sharp edges do the work. If you are drilling deep, pull the bit out slightly every few seconds to clear the dust.
