The Makita 7-1/4-Inch Circular Saw with Dust Collector is ideal for cutting fiber-cement materials. With a powerful 13 AMP motor, the 5057KB can cut five 5/16-inch siding boards in a single pass. The saw features a dust collection container engineered to reduce the amount of dust created while cutting. The bearings and switch are dust-proof to keep them working longer. The control lever enables the guard to be retracted for easier plunge cuts, and bevel cuts from 0 to 45 degrees.
