The Milwaukee 10-piece Plumbers-hole Saw Kit comes with 6-hole saw sizes, 3/4 in., 7/8 in., 1-1/8 in., 1-1/2 in., 1-3/4 in. and 2-1/4 in. Features Rip Guard teeth that were built with more steel behind the cutting edge for added strength. These teeth give you increased productivity on the job site as well as better-hole quality and are backed by a limited lifetime tooth break warranty. Each-hole Dozer is coated with a low friction, thermoset paint that provides faster cutting speed in wood and more-holes cut per battery charge. The-hole Dozer comes with a Plug Jack, an all-access slot design that allows for full access during plug removal. The Plug Jack enables access lower into the cup for thick material and higher toward the teeth for thin material, eliminating wasted downtime between-holes.
