Price ListThe HM produces a hole that is: 1 -1/32 DIA X .875 Arc to Flat.
The HM uses a 1/4" square pilot pin with a flat on one corner to key the rotation of the punch.
The pilot pin is retained by a setscrew which allows for easy adjustment and replacement should it become damaged.
The bolt in the top of the punch is replaceable and should be replaced periodically to prevent wear on the handle of the punch.
