Machine Bit 3/8 Diameter (Left Hand)

The LH-DKDB bit is made of cobalt steel for a long life. This left-hand drill bit is for use in the middle spindle of the fully automatic machine DK3100.

The Kreg Left-Hand Stepped Drill Bit is uniquely designed for exclusive use with the Kreg DK3100 Pocket-Hole Machine. Made from cobalt-steel, this heavy-duty drill bit will withstand years of use. The bit features a one-piece design, which eliminates clogging and provides a much smoother and faster drilling stroke than drill bits with replaceable center drills.
