These drill kits contain a drill guide bush and a lip and spur drill with drill stop and hex key. Precisely cut from high pressure laminate the drill guide bush enables PEANUT® Jig and Mini Jig users to accurately drill holes for dowels. The drill guide bush is compatible with all Mini Jigs and the Peanut® Jig Inserts MK2 (square shape).
