Heleta"s abrasive metal Metal Cutting Wheels are formulated with aluminum oxide grain and fiberglass reinforcement for heavy duty cutting. This formulation provides consistent, aggressive cutting and longer wheel life. We take great care to make sure our Metal Cutting Wheels are well balanced which results in smoother vibration free grinding and cutting. Heleta utilizes an industry recognized icon system to help users identify the right bonded abrasive wheel for their application. There are also several key identifiers to look for on a Heleta"s wheel; RPM, wheel size, thickness, profile type and arbor size to ensure the correct product is used.
