Polinox compact grinding wheels

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 straight grinders, flexible shafts and bench grinders is particularly suitable for working on smaller surfaces. Medium-hard version with increased edge strength and tool life for coarse deburring and cleaning applications. An adapter is included with the 150 x 25 mm diameter grinding wheels, which allows the centre hole diameter to be reduced from 25.4 mm to 20 mm.
