Description

POLINOX® unitized discs are used for face-down grinding with variable speed angle grinders. Ideal for larger surfaces. The compressed, non-woven material is bonded to a fiberglass back.

POLINOX® unitized discs are made 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 create 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.

Soft version with excellent adaptability. The durability, grinding performance, and very high surface quality are maintained at the same time. Very good for work on contours.

Advantages
  • Cost-effective due to high abrasive performance and durability.
  • Produces very good surface quality.
  • Can be profiled as desired, enabling optimal adjustment to the contour.
Recommendations for use
  • Considerably reduce peripheral speed for work on materials with poor heat-conducting properties, e.g. titanium and stainless steel.
  • For the best performance, use with a recommended peripheral speed of 3,000-6,000 SFPM. 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.
