Key specifications

Choosing the right option

Choose by hole diameter. The 10, 11 and 13mm bits have a 6.35mm shank, and the 10 and 11mm sizes are also for a quick change impact driver (over 14.4V); from 14mm the shank is 10mm. The 21, 22 and 27mm bits are 210mm long and need the lower 1,500rpm speed limit. For more reach in softwood see the 4S Series standard-length auger drill bits or the 4L Series extended-length auger drill bits; for hardwood see the 8M Series medium-length hardwood auger drill bits or 8L Series long hardwood auger drill bits.
