Description
PFERD offers a wide range of coated and non-woven abrasive tools for face-down grinding, belt grinding, peripheral grinding, surface conditioning, polishing, and much more.
POLINOX® cross buffs consist of non-woven polyamide abrasive, into which abrasive grain is integrated. The wide range of hardness grades and different configurations allow a variety of surface structures and roughness levels to be achieved.
The non-woven abrasive is star-shaped and stacked in layers which are connected in the centre. It offers outstanding performance, specifically when used for tight work areas such as holes, recesses and hard-to-reach places.
Ideal for cleaning, deburring and fine grinding of inner surfaces and contours. Highly recommended for hard-to-reach places such as drilled holes and indentations.
