Cortool 3-inch cut-off wheel, type 1 flat cutting with 3/8 abor and mandrel, is typically considered the most efficient type of wheel for general all-purpose cutting, which provides more cutting surface and minimizes interference with the workpiece. Cortool 3-inch cutting wheels are exceptionally useful in grinders, die grinders, electric hand drills & high-speed saws. Earplug is included in this package for a safer DIY to block noise during your work! Cortool uses high quality aluminium oxide & white corundum grain, provides a fast initial cut rate and consistent performance for steel and other metal. Bonded with strong resin, the cutting wheels absorb excess shock, resist additional heat and provide moisture. In addition, Cortool 3-inch cutting wheels are reinforced with double layer fiberglass, which added support for high-vibration and heavy-duty industrial applications. Cortool 3-inch cutting wheels has an ultra-thin thickness of 1/16" which gives a more precise cutting. Faster, Cleaner Cuts with Less Effort and Heat Build up with minimal burrs and material waste.
