Dog Hole Bushings

These 3/4" and 20mm hardened steel bushings help you make an accurate dog-hole drilling guide using any 1 1/2" thick board.

Knurling on the bushing provides a mechanical lock when installed in an appropriately-sized hole (1" for the 3/4" bushing, 25mm for the 20mm bushing), and a projecting rim ensures that it rests perpendicular to the jig's surface.

Made in Canada.
