The best drill bit set for woodworking is usually a sharp, well-sized set of brad-point bits—not the biggest kit on the shelf. Brad points help place holes accurately in solid wood, while ordinary twist bits are often adequate for pilot holes and occasional repairs. Choose a set around the sizes you actually use, and check that its shanks fit your drill’s chuck.

What we cover
Choose the right bit for the job
For clean, accurately located holes in solid wood, brad-point bits are a strong default. Their center spur helps prevent the bit from wandering, and the outer spurs score the edge before the cutting lips remove material. That usually means less splintering than a general-purpose twist bit, especially when drilling across the grain.
Twist bits are cheaper and versatile, and they work well for many pilot holes, hardware installations, and rougher jobs. They can skate across a smooth surface unless you make a small starting divot or use a center punch. For plywood, veneer, and melamine, even a brad-point bit can chip the top layer; put painter’s tape over the entry point, use a sharp bit, and ease off as the bit exits.
For larger flat-bottomed holes, a Forstner bit is more appropriate than a standard set bit. Forstner bits can cut clean recesses and overlapping holes, but they need more torque and generate more heat. A compact cordless drill may handle small diameters; for large holes in hardwood, slow down and use a drill with enough power rather than forcing the bit.
Bit set options compared
| Set type | Best use | Trade-off |
|---|---|---|
| Brad-point set | Accurate holes in solid wood and many woodworking projects | Less useful for metal or masonry; thin bits can break if bent |
| Twist-bit set | Pilot holes, general repairs, and mixed materials | Can wander or leave rougher edges in wood |
| Forstner set | Large, flat-bottomed holes and hinge recesses | Costs more and puts greater load on the drill |
| Combination set | Occasional work across several materials | May include many sizes or styles you rarely use |
What to look for in a set
Start with the diameter range. A set covering roughly 1/8 to 1/2 inch handles many furniture, cabinet, and repair tasks. Smaller bits are useful for pilot holes, but very thin bits—around 1/16 inch, for example—can snap if the drill tilts or the work shifts. If you regularly bore larger holes, buy the larger bits you need separately instead of paying for an oversized assortment.
Check the shank, too. Most cordless drills use a three-jaw chuck, so round shanks are a safe, widely compatible choice. Hex shanks can make quick changes easier, but do not assume every hex-shank set is intended for a drill-only chuck or every accessory works equally well in an impact driver. A drill bit is not automatically impact-rated just because it has a hex shank. For woodworking, use the drill’s chuck rather than an impact driver unless the bit maker specifically approves impact use.
Look for clearly marked sizes and a case that holds bits securely. A durable case matters more than a large bit count if it keeps sizes legible and stops bits from rattling together. If you need a straightforward set for accurate holes, compare brad-point drill bit sets for wood. For occasional pilot holes and mixed household work, a basic twist-bit set may cost less and be entirely adequate.
Use bits well with a cordless drill
Clamp the workpiece or hold it firmly against a bench; do not try to steady a small piece with your hand near the bit. Set the drill to low gear for larger bits and high gear for small holes if your drill has two speeds. Start slowly to let the point locate, then apply steady pressure. If the bit stops cutting, do not keep squeezing the trigger harder: withdraw it to clear chips, check for a dull edge, and reduce pressure.
For a clean through-hole, clamp a scrap backer beneath the work. The backer supports the fibers as the bit exits and reduces tear-out. You can also stop when the center point just breaks through, then finish from the opposite side using that small hole as a guide. In hardwood, drilling deep holes in one continuous pass can pack chips into the flutes and overheat the bit. Pull the bit out periodically to clear them.
Match the pilot hole to the screw. As a practical starting point, the pilot should be close to the screw’s root diameter—the narrower core between its threads—not the full outside diameter. A pilot that is too small can split hardwood or stall the drill; one that is too large gives the threads little wood to grip. Test on a scrap piece when the screw size or wood species is unfamiliar.
Care, wear, and when to replace
Keep bits dry, clean off resin, and return them to their case rather than dropping them into a drawer. Resin buildup can make a bit cut poorly and run hot. A bit that burns the wood, wanders despite careful starting, or needs unusual pressure may be dull, dirty, or damaged. Check for a bent shank and chipped cutting edges before blaming the drill.
Sharpening small brad-point bits accurately can be difficult, and an inexpensive set may not justify professional sharpening. Replacing a worn common size is reasonable; replacing an entire kit is not. If you only drill a few holes a year, a modest twist-bit set plus a handful of good brad-point sizes may be better value than a premium assortment. If clean, repeatable holes are part of your regular work, spend more on the bit styles and sizes you use most rather than on the highest piece count.
