What the AI looks for in Hole Punches
- Material capacity
- Check the stated gauge capacity for mild steel and reduce it for stainless. Over-capacity punching breaks punches and dies.
- Throat depth
- Throat depth sets how far from the edge you can punch. A shallow throat limits use on wide panels.
- Matched punch and die
- Always pair a punch with the die of the same size. Mismatched pairs chip and leave ragged holes.
Brands that matter
- Roper Whitney: Classic sheet-metal hand punches.
- C.S. Osborne: Leather and gasket hollow punches.
- Malco: Sheet-metal hand tools.
What to avoid
- Cheap rotary punches for anything thicker than thin leather
- Punching hardened steel
