14 x 1/8 x 20mm Bonded Abrasives Cut-Off Wheels - Concrete - Pack of 10 14" X1/8" x 20 mm, Bonded Masonry, Cut Off Wheel.. The product is manufactured in China. The product is easy to use and highly durable. Features FOR CUTTING: This cut-off wheel is designed to cut concrete and other similar materials, such as mortar. Each cutting disc contains specially sized abrasive grain and layers of fiberglass reinforcement sheet pressed into the cut-off wheel form and then baked at high temperatures. These wheels can be used on a wide range of tools, including right-angle grinders and cut-off saws. BONDED ABRASIVE DISC: This Virginia Abrasives bonded abrasives cut-off wheel uses a resinoid bond that microfractures during use, constantly exposing newer, sharper edges to maximize productivity, minimize overheating, and increase the life of the grinding wheel. The microfracturing of abrasive particles maintains the sanding disc's cut rate and performance!

It is used for fast cutting of stone, concrete, block, brick, and asphalt. It is not as tough as other grains due to its friability, but it is the right mineral for the previously mentioned applications. It is often used to cut soft, non-ferrous metals such as aluminum, copper, and brass. It is also used to cut PVC pipe quickly. SAFETY FIRST: All of our grinding wheels are marked with recommended applications and warnings for safe use. Be sure to read and follow the instructions. The maximum speed of grinding wheels is clearly marked on each wheel. Know the speed of the machine on which the grinding wheel will be used. Never exceed the maximum safe speed marked on the grinding wheel.
