Pferd 42781501 Combidisc CDR VRH Non-Woven Disc 50 mm, Grit 100 G, Coarse
Available
The Pferd Combidisc CDR VRH is the hard type non-woven disc for the COMBIDISC CDR clamping system, in 50 mm and 75 mm diameters, made with aluminium oxide (A) in grit 100 G (coarse, yellow-brown), 180 M (medium, red-brown) and 240 F (fine, blue) (manufacturer-stated).
The catalogue describes the hard type VRH as suitable for general work on small and medium-sized metal surfaces, for example removing rough grinding traces, removing oxidation and light deburring work, leaving matt and satin-finished surfaces (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, and the abrasive disc holder is ordered separately (manufacturer-stated).

Each item number is one diameter and grade combination. The catalogue prints an optimum speed range for each diameter and no maximum speed.
Selecting the right option
Pick the grade from the table: the catalogue gives grit 100 G as coarse (yellow-brown), 180 M as medium (red-brown) and 240 F as fine (blue), and a higher grit number is a finer abrasive. Match the diameter to your abrasive disc holder, which is ordered separately. The catalogue prints an optimum speed for each diameter and no maximum speed, so confirm the rating before use.
