Circular saw blades are used for cutting tasks – large and small – including steel and wood framing, plywood sheathing, aluminum storefront tubing and building demolition ? to name a few. The number of teeth on the blade determine the speed and finish of your cut. The fewer teeth a blade has, the faster the cut will be, while blades with more teeth will produce a cleaner cut. And Allfasteners has the premium quality circular saw blades you need for use in many materials.
