Kreg® 易設定鑽頭（附止動環與量規/六角扳手）

The etched markings are genuinely easy to read even in dim light, and the stop collar locks down tight without slipping. Makes switching between 3/4" and 1 1/2" settings on my jig feel almost effortless.

Third time I've bought this set because I keep lending it out and forgetting who borrowed it, and the stop collar still locks down tight every single time. The gauge wrench doubles as a hex key, so I never lose a separate tool in the shop.

The etched markings on the shank are genuinely easy to read, even in my dimly lit workshop, and the little hex wrench stays handy right on the gauge. Set up two dozen pocket holes for 3/4" material without having to guess or re-measure once.
