Replace wheels less often with Temper Point TM grains that are built tougher to maintain razor sharpness for up to 50% longer life. Get a longer lasting cutting edge that resists wear-and-tear with enhanced adhesion between the coated grains and resin. Efficiently cut a wide range of metals including carbon steel， stainless， and nickel-based alloys with the wheels thin designs and high-grain concentration. These wheels are exceptionally durable and are built with 2 sheets of fiberglass for optimized strength to help to reduce breakage.FeaturesThin .045" wheel design for fast burr free cuttingProprietary aluminum oxide grain combination for aggressive cutting actionProprietary material mix ensures durable long life wheels2 full sheets of fiberglass for durability and safetySpecificationsThickness: 0.045Specs: A60TMax speed: 13，300 RPMQuantity: 1Application: Thin metalType: 13，300 RPMSize: 7/8" arbor
