The Merit 08834181724 Full Tapered Coated Spiral Roll is engineered for precision deburring, chamfering, and polishing tasks in confined spaces. Designed with a 3/8" maximum roll diameter and a 1-1/2" overall length, this spiral roll features a 1/8" pilot hole for secure attachment to compatible mandrels. Constructed with a coarse 60 grit aluminum oxide abrasive bonded to an X-weight cotton backing, it delivers consistent performance and durability. Operating at a maximum speed of 23,000 RPM, this tool is suitable for high-speed grinding applications. The tapered design allows for effective work on smaller areas, making it ideal for finishing and polishing channels, fillets, radii, and small holes. Commonly used on ferrous alloys, high tensile materials, and wood, the Merit 08834181724 spiral roll is a reliable choice for achieving smooth finishes in intricate workpieces.
