Quick-Change Metal Punching Tool For Electrical Panel Knockouts

Product Details:
The tool set works with a hydraulic driver or a ratchet spanner. You drill a pilot hole, insert the draw stud, and place the punch and die on either side of the panel. As you tighten, the punch cuts through mild steel or stainless up to 2 mm thick, leaving a burr-free hole edge that needs no filing.

Different punch heads are stored in a labeled case, so you can quickly find the size matching your conduit connector. The quick-change collar snaps into place, reducing downtime between hole sizes. This is especially helpful when you are building a control panel with multiple cable gland sizes.

Keep the cutting edges lightly oiled, and do not force the tool on thicker material than rated. The punches can be sharpened several times. For electrical workshops and field installations, a portable metal punching tool kit eliminates the need for step drills and produces professional-looking knockouts every time.
