Pferd 42779141 Combidisc CDR PNER Disc 50 mm, Aluminium Oxide, H (hard), coarse
Available
The Pferd Combidisc CDR PNER is a non-woven disc for the COMBIDISC CDR clamping system, in 50 and 75 mm diameters, made with aluminium oxide (A). This page lists 8 items in the W (soft), MH (medium-hard) and H (hard) versions, in grit G and F (manufacturer-stated).
The catalogue describes the PNER type as giving a very fine, uniform surface finish that, depending on requirements, is a sufficient preparation for high-gloss polishing, and as particularly suitable for work on small and medium-sized surfaces on stainless steel (INOX) components (manufacturer-stated).
The discs are described as very comfortable due to ease of use and low-vibration working, with no disruptions in use from adhesion, slipping or coming loose. They can be changed quickly with the COMBIDISC clamping system; the abrasive disc holder is ordered separately (manufacturer-stated).
