POLINOX® cross buffs are made 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.
