This Heavy Duty Cobalt Steel Drill Bit Is Uniquely Designed For Use With The 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. Note: This Bit Features An Exclusive Left-Hand Thread Designed For The Center Spindle Of A Dk 3100 Only (H6828). Will Not Work With Standard Kreg Jigs Or Other Pocket-Hole Machines.
The one-piece design elminates clogging and provides a much smoother and faster drilling stroke than other pocket hole drill bits. The step drill bit drills the pocket hole and the pilot hole in one process. Made with Cobalt steel to increase drill bit life. For use specifically in Kreg's DK3100 Multi-Spindle Pocket Hole Machine. Not for use with any other pocket hole machine or manual jig.
