POLINOX® cross buffs are made of of non-woven polyamide abrasive, into which abrasive grain is integrated. The non-woven abrasive is staggered and stacked around a core and resembles a star. Ideal for hard-to-reach places like drilled holes and indentations. POLINOX® cross buffs are designed for cleaning, deburring and fine grinding of inner surfaces and contours.

Pferdergonomics:
PFERDERGONOMICS recommends POLINOX® cross buffs to reduce vibration and noise produced during use and to improve comfort when working.
Recommendations for use:
For the best performance, use with a recommended peripheral speed of 2,000-4,000 SFPM. This provides an ideal compromise between stock removal rate, surface quality, thermal load on the workpiece and flap wheel/cross buff wear.
Safety notes:
The maximum permitted peripheral speed is 6,300 SFPM.
Safety notes 1:
For safety reasons, the maximum permitted rotational speed indicated must never be exceeded.
Other Details
Conforms to contours due to high flexibility.
Cool grinding and low thermal load on the workpiece.
The open structure and high flexibility of the non-woven material prevents loading.
