Outstanding performance: The Carbide sanding block disc is specially developed for hard materials and offers high dimensional stability, long service life and outstanding grinding performance. Efficient grinding: when processing very hard materials such as carbide, this soft grinding wheel with hardness J continuously releases sharp grain and prevents glazing Versatile use: ideal for deburring, sharpening and edge processing (chamfering, rounding) of carbide tools - the straight design maximises precision Universal mounting: thanks to integrated reducing sleeves, the ceramically bound sanding block disc can be easily mounted on sanding block spindles of various sizes (32/25/20/16 mm) Box contents: 1 x PFERD carbide sanding disc, with diameter 125 mm and width 20 mm, bore: 32 mm + reducing sleeves, abrasive silicon carbide (CN), grain size 80, hardness J, soft, Manufacturer: August Rüggeberg GmbH & Co.
