PFERD's POLINOX fiber-backing disc designed for large surface finishing applications

PFERD introduces the POLINOX® fiber-backing disc, designed for long service life and working on large surfaces with variable speed angle grinders. This disc has non-woven abrasive flaps with fiberglass backing for face-down finishing work. Its abrasive properties are tailored to a variety of metal machining and grinding applications. It uses aluminum oxide A abrasive.

Discs feature the same construction as PFERD’s PNZ and PNL flap wheels and finishing drums. Interleaved discs (PNZ type) come in two different grits while radial discs (PNL type) come in three different grit sizes. The PNZ type will create a coarser surface finish and remove more material than the PNL type. Both discs are available in two diameters, 4-1/2-in. and 5 7/8-in. arbors.

The material on the fiberglass backer is approximately ¾-in. thick and will create a non- linear surface finish. These discs are ideal for step-by-step fine grinding, and prep-to-paint applications where cosmetics are not an issue.
