This section covers twist drill bits for metal, wood and plastic, along with step drills, masonry bits and drill bit sets. Lengths include stub (screw machine), jobber, taper and extra-long. Materials range from general-purpose high-speed steel (HSS) to cobalt for stainless and tough alloys and solid carbide for production machining. Sizes come in fractional, letter, number (wire gauge) and metric series, with black oxide, bright, gold oxide and titanium nitride finishes.
What to check before you order
- Workpiece material. HSS suits mild steel, aluminum and wood. Cobalt holds up in stainless. Carbide-tipped masonry bits are for concrete and block in a hammer drill.
- Point style. A 135 degree split point self-centers and cuts harder metals. A 118 degree point is common for general work.
- Length. Stub length bits are stiffer and wander less. Use jobber length for general work and taper or extra-long only when you need reach.
- Shank. Check the chuck. Reduced shank bits fit a 1/2" chuck on larger sizes, and SDS shanks fit rotary hammers.
- Tap drill sizes. Number and letter sizes exist mainly to drill tap holes. Keep a chart near the drill press.
Common questions
What is a jobber length drill bit?
It is the standard general-purpose length, long enough for most hand drill and drill press work while still fairly rigid.
