Description

POLINOX unitized wheels PNER consist of multiple heavily compressed, non-woven layers, which are bonded together by a special grain/resin system. The different combinations of compression, fibres, grain and the appropriate bond results in non-woven products that offer a very good surface finish, high stock removal rate and long tool life. These tools can be used for a wide range of work on surfaces, from relatively coarse grinding to preparing the surface for polishing.

The version for angle grinders and fillet weld grinders is particularly suitable for working on fillet welds and hard-to-reach slots and indentations.

Medium-hard version with increased edge strength and tool life for coarse blending and polishing tasks. Well-suited for working on edges.

Advantages

High economic efficiency due to high abrasive performance and long tool life.
Produces very good surface quality.
Can be profiled as desired, enabling optimal adjustment to the contour.

Recommendations for use

Considerably reduce cutting speed for work on materials with poor heat-conducting properties, e.g. titanium and stainless steel.
For the best results, use at a recommended cutting speed of 15-30 m/s. This provides an ideal compromise between stock removal rate, surface quality, thermal load on the workpiece and tool wear.

Safety notes

For safety reasons, the maximum permitted rotational speed indicated must never be exceeded.
