FEATURES: 

► Make corners really square with this chisel.

► First, chisel out your hinge mortise as usual,

     then place this self-aligning chisel up

     against each mortise corner, and hammer

     the Spring loaded chisel shaft once to cut a

     perfect 90° corner for a perfect fitting hinge

     plate. It’s faster and more precise than a

     reguler chisel.

► Carbon steel shaft with heat treatment and

     aluminum base.

► Cutting edge : 3/8" (9.5 mm)

► Max. working depth : 5/8" (16 mm)
