About this product
This sheet metal nibbler is a hand notching tool that roofers and sheet metal mechanics use to cut narrow slots and notches in panels and flashing. On standing seam work, the classic use is notching the seam legs at the eave, ridge or a transition so the panel end can be folded over a cleat or turned down cleanly, without cutting with snips and leaving a split that can tear.
A hand notcher bites out a narrow strip with each squeeze. Because it nibbles rather than shears, you do not need to pre-punch or drill a starting hole, and you can stop the slot exactly where the fold line will be. The brand and exact capacity of this tool are not on the old listing, so call us and we will confirm the model, the notch size and the maximum thickness before you order.
The Masc Nibbler in this catalog is a German-made notcher designed for the same standing seam job, with published capacities by material. For straight and curved cuts, see the Malco aviation snips and the WUKO Cutter 1070, and for folding the notched end, the WUKO Flat Nose Pliers or a Malco hand seamer.

Do I need to drill a starter hole?
No. A hand nibbler bites out its own slot, so no pre-punching is needed.
