Milwaukee Tool’s Hole Dozer bi-metal hole saw is built to withstand the most punishing applications. Equipped with the first-ever lifetime warranty against tooth breaks, this saw brings high durability and increased productivity to users. The saw features the Rip Guard tooth form where each tooth is built with more steel behind the cutting edge for added strength. The added tooth strength along with 8% cobalt give added life to the teeth, allowing for increased jobsite productivity and continued hole quality. The saw also features the Plug Jack, an all-access slot design that allows full access during plug removal. The Plug Jack gives access lower into the cup for thick material and higher toward the teeth for thin material. The Hole Dozer comes in 56 different diameters ranging from 9/16” to 6”, as well as in a variety of general purpose and specialty mix kits.
