Ceramic fibre disc. High performance. Ceramic abrasive is tough dense abrasive and extremely long lasting. Due to its micro structure extremely small micron size particles break off during grinding, producing very many new cutting edges. Because it stays sharp especially when used in medium and high pressure operations it cuts at a higher rate than other abrasives. Recommended on forged and carbon steels, high nickel and cobalt alloys. Grit sizes: P36 Price per 25 discs. You should ensure that you are fully informed on the safe operation of abrasive cutting and grinding wheels.
