The Mayhew Steel 5/32-Inch Starting Punch rounds out the larger end of Mayhew’s starting punch sizes. Mayhew Steel gives this punch the same stout, break-loose tip design used across the starting punch line, scaled up to handle the largest pins a gunsmith is likely to run into on trigger housings, frames, and heavier takedown pins. Breaking a pin free cleanly at this size matters just as much as it does on the smaller starting punches, since a pin that mushrooms under the first hit can be difficult to remove and may need to be drilled out entirely. Pairing this punch with a matching 5/32-inch pin punch covers the full removal process from break-loose to full drive-through.

Key Specifications

• Sized at 5/32 inch.
