Milwaukee's Heavy Duty 4/6 Hole Saws feature a multiple tooth design with varying tooth sets and gullet depths. The deeper gullets provide more efficient chip clearance with less heat build up thus requiring lower feed pressure - ideal for high RPM portable drills. These Hole Saws are constructed with a minimum 3/16 inch thick steel back resulting in a more durable, longer lasting hole saw. Made of Bi-Metal construction, the high speed steel teeth are electron beam welded to the high alloy steel body. Containing cobalt, the teeth are ideal for both wood and metal applications. Milwaukee Hole Saws provide an economical means of creating up to 6 inch holes for the general construction, plumbing, electrical, maintenance and remodeling industries.
