Snap Lock Punch for Sheet Metal

The Malco SL1R is a hand-operated punch that forms a 3/8 in snap-lock hole in sheet metal up to 8 in overall length. It is built for HVAC installers, duct fabricators and maintenance crews who need a repeatable joint without fasteners.

Suited for thin-gauge ductwork; not for heavy plate

The tool handles aluminium up to .035 in, copper up to .023 in, galvanised steel up to .028 in, mild steel up to .024 in and stainless steel up to .018 in. Buyers who need to punch thicker plate or larger hole diameters should look at a different class of equipment.

Consistent leverage through compound handles

Redline handles with compound leverage multiply grip force so each punch completes with one hand without re-gripping. The black-oxide steel frame resists corrosion during daily shop use, and the latch opens and closes smoothly for rapid repetitive cycles.

Questions about this item

What sheet-metal thicknesses can the 3/8 in punch handle?

The punch cuts aluminium up to .035 in, copper up to .023 in, galvanised steel up to .028 in, mild steel up to .024 in and stainless steel up to .018 in.

Will the compound-leverage handles reduce the hand force I need compared with my older straight-leverage snips?

The Redline handles use compound leverage, so each squeeze delivers more punch force for the same grip effort than a simple-leverage tool.

How can I confirm the latch is engaging correctly after my first few punches?

The latch should snap shut with a distinct click and the jaws must align flush; a clean 3/8 in hole in the rated material confirms proper operation.
