Milwaukee's fiber cement cutting circular saw blades provide a significantly longer life than competitive Carbide tipped blades when cutting fiber cement materials. The polycrystalline diamond (PCD) tips deliver up to 75X the life of a traditional Carbide tipped blade. 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. 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.Find the FC BLD PCD 7-1/4X5/84T at Ace.
