Deburring Wheels are used to clean, blend, deburr, finish, and polish the metals, and glass. These deburring wheels are perfect for light to heavy precision blending, deburring, and cleaning. It offers a uniform finish to parts and deburrs the workpiece quickly and easily than hand finishing and minimizes heat build-up to reduce the risk of discoloration and warping on heat-sensitive substrates and produces a professional finish without undercutting, gouging, or distorting the workpiece. Here are the different variations of the Convolute Deburring Wheels.
