These high-quality bits help you drill holes for shelf pins or the metal sleeves that fit them when using our Shelf Pin Drilling Jig (74448, sold separately). Their spring-loaded housing features a high-speed steel bit with a special tip grind that minimizes tearout. A 90° shoulder reduces the end of the housing to 3/8” O.D., so it fits snugly into the guide holes of the jig template for perfectly centered hole placement. During drilling, the white nylon bushing on the shoulder remains stationary while the bit spins, to protect the jig plate from possible scratches and friction damage.
The 5mm and 1/4” drill bits (75878 and 76583) are exact replacements for the bits that come standard with the Shelf Pin Drilling Jig. The 7/32” and 9/32” bits (76765 and 79433) drill holes for optional metal sleeves (GRP41610 and GRP41613, sold separately) that fit 5mm or 1/4” shelf pins.
