Pferd Untapered Cartridge Roll, 3/8" x 1", 1/8" Arbor, Pack of 50

The PFERD TOOLS POLIROLL Cartridge Roll is a high-performance abrasive designed for precision grinding, deburring, and finishing in hard-to-reach areas. Constructed with premium aluminum oxide abrasive spirally wound around a durable backing, this cartridge roll delivers consistent cutting performance and long service life on a wide variety of metals and engineering materials. The self-sharpening abrasive grain maintains aggressive cutting action throughout the life of the roll, while the self-tensioning design securely grips the grooved, conical arbor for safe, reliable operation. Its compact 3/8" diameter makes it ideal for grinding inside holes, contours, radii, and other confined spaces where larger abrasives cannot reach. Perfect for use with straight grinders and flexible shaft tools, the POLIROLL cartridge roll is well suited for deburring, edge blending, weld seam finishing, sharpening, and fine grinding on steel, stainless steel, titanium, cast iron, brass, copper, plastics, and other materials.
