Famag 5点セット 深さストッパー フォースナービット用

The brass thumbscrews make swapping these between bits effortless, and the nylon insert keeps them locked tight without marring the shank. I've been using them for cabinet hinge mortises and each hole comes out exactly the same depth.

These depth stops slip right onto my Forstner bits and lock down tight, so every hole in a cabinet run comes out the same depth. Setting them takes maybe ten seconds, which beats fussing with tape and a pencil every time. Wish I'd grabbed a set years ago.

Finally, no more measuring and marking every single hole—just slip the stop on and drill the exact same depth every time. The brass locking ring holds tight even after dozens of holes.
