POLINOX unitized discs are used for face-down grinding on speed-adjustable angle grinders. Especially well-suited to work on larger surfaces. The compressed, non-woven material is bonded to a glass-fabric base. POLINOX unitized discs 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. Medium-hard version with increased edge strength and tool life for coarse blending and polishing tasks. Well-suited for working on edges.
FEATURES:
- 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.
SPECIFICATIONS:
- Abrasive: Silicon carbide SiC/C
- Dia. external: 125 mm
- Dia. hole: 22.23 mm
- Grit size: fine
- Max. RPM: 10000 RPM
- RPM, optimum: 5400 RPM
- Version: MW (medium-soft)

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.
