These tools simplify making a square hole up to 3/8" deep in softwood or hardwood, typically used to accommodate square plugs in decorative applications such as in Greene & Greene style furniture.

Just drill a hole slightly undersize (3/64" smaller than the size of the punch) and position the punch over the hole; with a few hammer taps, it cuts the hole square, with smooth walls and 90° corners. Punch tips are machined and ground from hardened O1 tool steel (Rc 48-52) and combined with shanks of softer steel for shock absorption. Shanks have a black-oxide finish to resist rust, and are grooved for grip.

The 3/16", 1/4" and 5/16" sizes measure 2 3/4" long overall; 3/8", 7/16" and 1/2" sizes are 3 1/16" long. Available individually or as a set of all six.

Made in Canada.

For easy sharpening of the punches, we offer a pair of diamond hones separately.
