This kit includes the same Easy-Set stop collar and material thickness gauge/hex wrench that come with Kreg® 300 Series pocket hole jigs. The collar features a window that aligns with the engraved markings on the Kreg® Easy-Set pocket hole drill bit to make setting the bit at the correct depth easy for 1/2 in, 3/4 in and 1-1/2 in materials. The material thickness gauge allows you to easily determine material thickness (1/2 in, 3/4 in, 1-1/2 in) and has a built-in hex wrench for tightening the stop collar. Collar also fits all other standard (3/8 in dia) Kreg® pocket hole drill bits.
