Description

For general grinding work on metals and other materials.

POLIROLL cartridge rolls consist of spirally wound, coated abrasives. The abrasive grain is embedded in the resinoid coating on the sturdy backing material, which achieves the best possible abrasive performance.

Advantages

Consistently high grinding performance throughout its entire tool life thanks to ongoing exposure of fresh abrasive grain during application.
Secure fit when in use due to self-tensioning provided by grooved, conical arbor.
Easy tool change.

Recommendations for use

Grind with the point rather than the flat surface so as not to damage the bond through the effect of heat.
Mount POLIROLL with the bonded side facing towards the arbor.
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, the maximum permitted rotational speed indicated must never be exceeded.
