Knockout die for hydraulic tools

The Greenlee 7212SP-1-1/4D is a steel knockout die designed for use with battery-hydraulic or manual-hydraulic punch drivers. It creates a round hole with a nominal size of 1 1/4 in and an exact diameter of 1 7/10 in. The die works on aluminum, brass, copper, fiberglass, mild steel and plastic up to 10 gauge thickness.

Compatibility and capacity check

Confirm that your hydraulic driver accepts Speed Punch series dies before ordering. The die handles a maximum sheet metal capacity of 10 ga for both steel and aluminum. No draw stud is included, so verify you have the correct stud for your driver model. The slug splits in half and falls free from the die and stud during operation.

Ideal for electricians and panel builders

This single die suits professionals who need a precise 1 1/4 in knockout in conduit boxes or enclosures. It is not for installers who require a complete punch kit with draw studs or pilots included. Buyers needing multiple hole sizes or threaded conduit entries should look at a different solution.
