Natural Roofing Slate Hand Punch

The NSP1 Slate Punch produces a clean, recessed nail hole in 4 – 8 mm natural roofing slate.  A big 2-1/2-inch (63 mm) throat depth allows convenient placement of the punch tip on the flat, unfinished side of the slate to create a desirable nail hole recess on the natural finished side as it punches through.  Hardened all-steel construction with rust-resistant nickel plate and black oxide finishes ensures long service. The tool steel punch component is also replaceable.

The Malco NSP1 Slate Punch also features ergonomic RedLine Handle technology.  An Engineered handle opening compliments the natural power stroke of any user’s hand and maximizes the powerful 7:1 mechanical advantage of compound-leverage head to handle linkage.  Comfortable handle grip contours, a non-slip grip insert, spring handle actuation and a thumb-operated handle latch ensure a natural fit and feel for comfortable one hand operation anywhere on the job.
