All Malco Gutter Outlet Punch and Dies make clean, accurate hole cuts in .032" (0.81 mm) aluminum gutter. Ample throat clearance allows these lightweight outlet punches to work over the front edge of gutter to quickly line up cuts. Fastener holes are provided in the tool frame base for optional bench mount application. An easy ratcheting mechanism and angled punch-blade provide smooth cutting action. High carbon steel blades on punches assure long service life and are also easily replaceable. Heat treated components and weather resistant finishes provide added tool strength and durability.
