Pferd 42811305 POLIROLL PR 12 x 35 mm Cartridge Roll, Aluminium Oxide, Grit 50

The Pferd POLIROLL PR is a cylindrical cartridge roll made of spirally wound, coated abrasive with aluminium oxide grain, mounted on a grooved, conical arbor (ordered separately). This page lists 9 items in 6 x 25 mm, 6 x 35 mm, 9 x 35 mm and 12 x 35 mm, grits 50, 80 and 150.

The catalogue describes the aluminium oxide A version as suited to general grinding work in hard-to-reach areas on metals and other materials (manufacturer-stated).

Fresh abrasive grain is exposed as the roll wears, and the roll is held securely by the self-tensioning grooved, conical arbor, which also makes tool changes easy (manufacturer-stated).

Each item lists its own optimum speed, maximum speed and suitable arbors; the maximum permitted peripheral speed is 11 m/s and wet grinding is not permitted (manufacturer-stated).

Common specifications

Key specifications

Diameter (D) and length (T) are in millimetres. Each item number is a separate size and grit.

Selecting the right option

A higher grit number is a finer abrasive. Choose the size for the area you are working, then pick the arbor shown in the table row for that item, since the suitable arbor depends on the size. The maximum permitted rotational speed indicated must never be exceeded, and the roll is not permitted for wet grinding (manufacturer-stated).
