![]() ![]() They can be used to cut holes in wood, ferrous and non-ferrous metal, ceramics, marble, glass, slate, granite, and fiber cement products. About Exchange-A-Blade hole sawsĮxchange-A-Blade hole saws are market leaders in quality and value. A limited number of these hole saw products are also available in our non-exchangeable brand, Stay Sharp. Like all EAB Exchange-A-Blade green exchange products, our bimetal, carbide-tipped, and diamond hole saws are fully exchangeable-you buy it, you use it, and when you bring it back to the store where you bought it, you’ll get a credit towards the purchase of your next EAB hole saw. Exchangeable to save you money and save the planet Diamond holes saws can be used to cut fiber cement, but carbide tipped hole saws are preferred. *Indicates that water is required for cutting NOTE:Ĭutting wood, aluminum, brass, mild steel, and stainless steel is not recommended with a diamond hole saw. Recommended carbide tipped hole saw RPMs for wood and fiber cementĬutting aluminum, brass, mild steel, stainless steel, ceramic, marble, glass, granite, slate, and terrazzo is not recommended with a carbide tipped hole saw.

Note that when using diamond hole saws not only is a slow speed important but it is critical that you use water as a cooling lubricant while cutting. There is nothing worse than having a diamond hole saw slide across a granite tile and destroy the surface just because we were impatient and cutting too fast. ![]() When cutting hard materials slow speeds will give you more control as well. If you are cutting through very hard material such as steel or ceramic tile and the suggested speed is 300 RPM then simply drill very slowly. For example, if your drill is rated at 0 to 3,000 RPM and the suggested cutting speed is 1,500 RPM then simply run your drill at half speed. What the hole saw RPMs mean or how can I gauge the speed of my drill?Īlthough portable drills do not come with a speed gauge, most provide variable speeds and many even offer dual speed transmissions for a wider range of speed control. By following these guidelines you will reduce heat build up and hole saw burn out. However, each substrate hardness and density varies and needs to be cut at the correct speed to provide a precision cut and extended tool life.įor example, as the hole saw diameter increases, the speed, or RPM, should decrease and harder, denser materials need to be cut at slower speeds. Bimetal hole saws will allow us to cut all manner of wood and metal products diamond hole saws are suited to tile and masonry and carbide tipped are best for high speed wood and fiber cement. Modern hole saws offer various cutting profiles that allow us to cut a wide variety of materials.
