Infinity Tools Squared Corner Chisel

The Infinity Tools Squared Corner Chisel instantly squares up the rounded corners left behind when you rout a hinge or lock mortise. Press the chisel into the corner of the mortise, tap the top with a mallet, and you get clean, crisp, square corners in seconds. It’s an essential finishing tool for anyone fitting hinges and hardware, and a handy addition to our chisels and gouges selection.

Router bits leave radiused corners, but hinges and many hardware mortises need crisp 90 corners. Rather than paring by hand, this corner chisel registers in the mortise and cuts both walls square with a single mallet strike. The result is a clean corner and a perfect hardware fit, fast.
