Milwaukee's wood cutting, combination blades provide cleaner cross cuts and faster ripping to improve your productivity. An aggressive ATB-R tooth pattern minimizes tear out in the cut material while increasing the speed of cut. An anti-friction coating keeps the blade cool while cutting and resists corrosion & gumming. Laser cutting technology creates the blade from 100% sheet steel to ensure a stable blade that increases cutting accuracy. 12 in. blades are ring tensioned to further stabilize the blade. Laser cut vibration slots minimize wobble and warping during use. A thin Kerf design delivers faster cuts as well as more cuts per charge when using a cordless tool.
