3/8” cutting edge
Up to 1/2” deep
Squaring up inside corners after routing for door hinges is easy with this simple tool.
The base of the jig registers off the routed recess sides. A quick tap with a hammer and the spring retained chisel cleanly trims the inside radius leaving a clean sharp 90 degree inside corner.
The cutting edges of this chisel can be resharpened easily with a hand file.
