POLINOX cross buffs consist of non-woven polyamide abrasive, into which abrasive grain is integrated. The non-woven abrasive is star-shaped and stacked in layers which are connected in the centre. Particularly suitable for narrow application areas and hard-to-reach places such as drilled holes and indentations. POLINOX cross buffs are suitable for cleaning, deburring and fine grinding of inner surfaces and contours.
