About Spade Bits
Spade bits cut flat-bottomed holes in timber much faster than a twist drill of the same diameter. Alpha TurboBORE construction with self-feeding screw-tip pilot and spurred cutting edges that score the rim cleanly. 8mm-25mm+ in 150mm standard length, plus extension bars for deeper work. Used in framing, electrical chases and plumbing rough-ins.
Frequently Asked Questions
Spade: flat-bottomed hole, cuts fast at the surface, can splinter the back face, needs operator pressure to feed. Auger: helical flute clears chips at depth, screw-tip pilot pulls the bit through under power, cleaner side walls, slower but better for deep holes. Auger wins for anything over 75mm deep or for serious framing work.
Spade bits and augers will splinter the timber as they exit because nothing supports the wood fibres at the back face. The pilot-through-then-flip technique gives a clean hole on both faces. A backing board works for repetitive work where flipping the piece is impractical.
Use a stud finder or metal detector before drilling into framing, especially older walls where electrical staples or nail plates may be hidden. If a bit hits steel mid-cut, pull out and switch to a metal-rated twist drill to finish through the obstacle.
On vertical or angled drilling, use a guide block clamped to the work, or a self-centring jig. For high-precision work like timber dowel joinery, a drill press gives the cleanest perpendicular hole.
Match the extension's hex size to the bit shank. For very deep holes (over 300mm), drill in stages: 100mm at a time, withdraw to clear chips, advance again. Forcing a deep cut in one pass overheats the bit and packs the flute.
For best results, work on a bench with the bit clamped, follow the original cutting angle, and equalise both sides. A bench grinder works for heavy reshaping but removes a lot of material quickly. Learn on cheap bits first.
