Self-sharpening ceramic-grain abrasive belt with smooth backing. Impressive results when working on very hard surfaces; with an aggressive cut and a very long service life. Slightly less flexible than XK870F, but a very good alternative for wet grinding applications. XK870J is very popular for pre-sharpening knives.
- Self-sharpening effect constantly produces new sharp edges and thus enables much higher stock removal rates
- The additional grinding active layer VSM TOP SIZE ensures a cool cut and an extended service life
- High wear resistance
- Highly resiliant
