The Milwaukee Carbide Tooth Hole Saw features a new 3 TPI design that delivers fast cuts with the durability of a bi-metal hole saw and the life of a carbide hole saw. This Milwaukee hole saw provides the longest life in extreme and general purpose materials with the ability to cut stainless steel, cast iron, fastener-embedded wood, cement board, fiberglass, drywall, asphalt shingles and more with ease. Deep gullets clear material quickly while cutting, and Milwaukee's full-access slots solve the frustration of plug removal for increased productivity with less downtime between holes. The new slot design also provides increased pilot visibility for precise placement and faster chip ejection keeping cuts fresh. The carbide tooth hole saw has a cutting depth of 1.62 inches, allowing clearance to handle cuts in a wide range of materials. Milwaukee Hole Dozer Saws with Carbide Teeth are proudly made in the USA.
