Milwaukee carbide hole saw, Hole Dozer, 35 mm.

This hole saw offers up to 10 times longer tool life and higher heat resistance compared to standard bi-metal hole saws. It features aggressive 4-TPI toothing with a large chip space for faster clearing and set teeth for lower resistance. Unique notches provide easier core removal and better leverage on thin materials. Suitable applications include metalworking (stainless steel, alloy steel, aluminum) and composites (plastic, sandwich material, conductive floor tiles, fiberglass, coated panels, wood with nails).
