This heavy duty cobalt steel drill bit is uniquely designed for use with our high-production Pocket-Hole Machines. The bit itself features a one-piece design eliminating clogging and providing a much smoother and faster drilling stroke than drill bits with replaceable center drills. Idential 3/8” diameter also makes this a great premium drill bit upgrade for any of our Kreg Jigs.

 

Note: If you’re purchasing bit replacements for a DK 3100, be sure to also order a left hand drill bit (LH-DKDB) for the center spindle of this 3-spindle machine.
