Need to cut clean holes in tough materials? This 1-7/8 inch (48mm) carbide tipped hole saw is seriously tough! The industrial-grade carbide tips can handle stainless steel plates, hard metals, iron, mild steel, alloy steel, aluminum, and even plastics. The high-grade titanium-coated pilot bit ensures accurate starting and smooth cutting action.

Seriously, if you're tired of hole saws that dull quickly on metal, this carbide-tipped version will save you time and frustration while delivering professional results every time.
