Rotating abrasive discs - General Information For handheld use on angle grinders The abrasive media used here (aluminium oxide or silicon carbide, mostly in combination with different grit sizes) are bonded in a phenolic resin. Depending on the type of resin bonding (disc hardness), the quality of the abrasive medium and the type of glass fibre reinforcing fabric, the discs are intended for different applications of grinding processes, material groups, and performance classes. Overall cost analysis for grinding Material groups Specification Safe working Performance classes Steel / cast with very wear-resistant bonding systems. Special stainless steel types with very high cutting performance, also suitable for steel. Fe, S, Cl content < 0.1% (even "2 in 1" types) which reduces oxidation. Non-ferrous metals / aluminium with "soft" bonding system (prevents smearing). A60R-BFXA (Example) aHIB 3 A Grinding medium (A-Aluminium Oxide, ZA-Zirconium holoC.

B Type of bonding (B-Bakelite synthetic resin) F Fibre-reinforcement X Internal manufacturer designation A External fibre-reinforcement Consider markings and limitations of the tool; do not use cutting discs for roughing. Wear ear defenders, eye and body protection. Never exceed the indicated running speed (rpm) or maximum cutting speed (m/s). Never use grinding tools which are unmarked.
