What we cover
What a woodworking bit set should include
For clean holes in wood, a brad-point bit and a Forstner bit do different jobs. Brad-point bits drill ordinary holes with a pointed center that helps keep the bit from wandering. Forstner bits cut wide, flat-bottomed holes for hardware, plugs and recesses. A set containing one type is not a substitute for the other.
Check the sizes before buying. Brad-point sets commonly cover roughly 1/8 to 1/2 inch; Forstner sets often span about 1/4 to 1-3/8 inches. Those ranges vary, and the largest Forstner bits need a drill with enough torque and a secure chuck. For general cabinet and furniture work, useful sizes matter more than a very large count of rarely used bits.

Brad-point versus Forstner bits
A brad-point bit has a center spur and outer spurs that score the edge of the hole before the cutting lips remove wood. That helps produce a clean rim and improves accuracy in solid wood and many sheet goods. It is a good choice for through-holes for dowels, screws or small hardware. The center spur leaves a small mark on the far side, so use a backing board when the exit face must stay clean.
A Forstner bit makes a wider, flatter-bottomed hole and can cut overlapping holes or holes near an edge. Its rim-guided design can leave a clean opening, but it creates more friction and waste than a small brad-point bit. Large sizes can grab or overheat if pushed too hard. Use a drill press when possible; with a handheld drill, keep the tool square and start slowly.
Compare the main options
| Bit type | Best for | Typical trade-off |
|---|---|---|
| Brad-point set | Accurate small and medium holes in wood | Limited hole diameter; spur can mark the back face |
| Forstner set | Flat-bottomed recesses and larger holes | Needs more torque; larger bits can burn or catch |
| Combination set | Occasional work requiring both hole styles | May include fewer useful sizes of each type |
How to choose a set
For mostly dowel, pilot and general-purpose woodworking holes, start with a brad-point drill bit set for wood. Look for clearly marked sizes, a case that holds bits securely and a shank that fits your drill. A basic set is fine for occasional home projects, provided the cutting edges are reasonably sharp and the sizes you need are included. Cheap bits may need more frequent sharpening or replacement, but that is not a concern if they see light use.
Choose a Forstner bit set if your work regularly needs hinge cups, counterbores or flat-bottomed recesses. Check the largest diameter against your drill’s capacity and the job. A 1-3/8-inch bit can demand considerably more from a cordless drill than a 1/2-inch bit. A clutch can limit damage if a bit binds, but it does not replace a firm grip or careful feed pressure.
A combined woodworking bit set saves space and can be sensible for a beginner, but inspect the actual size list. “Many pieces” may count duplicate accessories rather than useful cutting sizes. If you already own a good brad-point set, buying only the Forstner diameters your project calls for is often better value than replacing everything.
Use the right drill setup
Brad-point bits in smaller diameters work well in a standard cordless drill. Forstner bits are slower cutting and put more load on the tool, especially in hardwood. Use a low gear and moderate speed for larger diameters; follow the bit maker’s guidance where available. Keep the work clamped. If a bit catches, an unsecured board can spin or pull the drill off line.
Do not use an impact driver as your first choice for these bits. Its hammering rotational action is designed for driving fasteners, not controlled boring, and can make it harder to maintain a clean hole. A drill press gives better control for deep, square holes, though a careful handheld drill is adequate for many jobs.
Avoid burning and tear-out
Burn marks usually mean the bit is dull, turning too slowly under heavy pressure, or packed with chips. Back the bit out periodically to clear waste, particularly in deep holes and dense hardwood. If the bit still smokes or leaves a scorched rim, stop and inspect the cutting edges rather than forcing it. Excess pressure can overheat the bit without making it cut faster.
For a clean through-hole, clamp scrap wood behind the workpiece so the bit exits into backing instead of tearing out the far face. For a Forstner recess, mark the depth on the bit or use a depth stop. Make a test hole in scrap of the same material: plywood and veneer can chip differently from solid wood, and the test also confirms that the chosen diameter fits the hardware.
Storage and maintenance
Keep bits dry and return them to their labeled slots. Loose bits rubbing together can dull their edges, and rust spots can affect cutting. Brush packed chips from the cutting edges after use. If a bit starts wandering, takes noticeably more force or leaves a rough rim, check for damage and sharpen or replace it. For occasional projects, replacing a worn inexpensive bit may cost less than paying to sharpen it; frequent users benefit more from a set with durable, serviceable cutters.
