A Heavy Duty Cut-Off saw is great for cutting masonry, concrete and even metal. If you need to run a wire under your concrete driveway it will be no problem with a cut-off saw. Before using any power tool, make sure you have the proper safety equipment. Long term use of a cutoff saw can take a toll on the operator. We recommend protecting your skin with the proper clothing, your feet with steel-toed safety shoes, your head with a hard hat or bump cap (depending upon conditions), your eyes with goggles or face screens, your ears with ear plugs, and your lungs with a mask or respirator for breathing protection in dusty conditions. Cut-off saws are some of the most powerful and versatile saws available to the general public.
