Makita Mforce Blade For Portable Saws. A revolutionary advanced tooth design that sets a new bench mark for blade technology. The dual beveled tooth face has sharper cutting edges and the “M” shape is like doubling the tooth count per blade. A greater wear area and more cutting surfaces means the MForce blade will last up to 2 x longer than traditional blades. A narrow kerf and plate reduces friction allowing for a lighter feed pressure, protecting the motor of your saw.
