panel punches

Brooks' Machine Products manufactures a full line of panel punch tools to accommodate most common jamb-nut receptacle connectors as well as many other panel knock-out requirements. Click here to review our punch sizes.

We produce special sized round, double flat, square, and rectangular panel punch assemblies, including special shapes custom tailored to our customers needs.

We manufacture our panel punches from high quality air-hardening tool steel and have them professionally heat-treated and black oxided for the highest level of strength and durability. 

All parts are 100% American designed and manufactured, including raw materials. We take great pride in our tools and in our workmanship, and guarantee all our products for two years.

Typical "Hoffman style Steel" boxes are very close to the limits. Some customers have converted our hand tools for use with hydraulic pulling units such as Greenlee and others with extended tool life and higher panel capacities, but we cannot guarantee such modified / altered usage.

Please let us know if you are planning on meeting or exceeding these capacities as we have optional tool designs that offer higher capacity at a slightly higher price set. Custom Punches are also guaranteed!
