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.

Turn round router corners square in seconds

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.
