Milwaukee's 12" 100T Ultra Fine Finish Circular Saw Blade (48-40-1228) provides a smooth finish and cutting efficiencies to improve your productivity. A high ATB tooth pattern provides a superior finish with minimal tear out in the cut material. 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" 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.
