Abrasive Cartridge Rolls POLIROLL - Aluminium Oxide Choose the POLIROLL cylindrical / cartridge size and grit to suit your application. For work on hard-to-reach areas, PFERD provides POLIROLL and POLICO tools with various - shapes, - dimensions, - abrasives and - grit sizes POLIROLL and POLICO tools consist of a coated abrasive wound in a spiral. The abrasive grain is embedded in the resinoid coating on the strong cloth backing material for maximum abrasive performance. Self-clamping due to a grooved conical tool holder ensures that the cartridge rolls remain securely attached during use. Advantages: - As the outer abrasive material of POLIROLL cartridge rolls wears off, fresh abrasive grain is exposed - Very good stock removal - Easy to replace due to special tool holder Application examples: - Deburring work on bores and hard-to-reach areas - Dressing fillet weld seams on metal structures - Deburring work on castings Recommendations for use: - Always grind using the tip and not the surface, as otherwise the adhesive will be damaged by the heat produced - Always position the cartridge rolls with the bonded side towards the tool holder - Use grinding oil that is suitable for the material in order to significantly increase the tool life and the abrasive performance of the tools. Safety notes: - The maximum permitted peripheral speed is 11 m/s - For safety reasons, it is imperative to remain within the stated maximum permitted rotational speed at all times
