Hoffmann Group 47 Rotating abrasive discs - General Information For hand-held use on angle grinders Here the abrasive media used (aluminium oxide or silicon carbide, mostly in combination with different grit sizes) are bonded in artificial 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. Material groups: Specification: A60R-BFXA (example): Overall cost analysis for grinding Steel / cast iron with very wear-resistant bonding systems. Special types for stainless steel with very high cutting performance, also suitable for steel. Fe, S, Cl content < 0.1 % (even in 2-in-1 designs) which oxidation. Non-ferrous metals /aluminium with „soft" bonding system (prevents smearing). AsBHi matt 3M HOLCX.

Wear ear defenders, eye and body protection. Never exceed the indicated running speed (rpm) or maximum working speed (m/s). Never use grinding tools which are unmarked. Destroy faulty grinding tools immediately. Duration of use Performance classes: Top quality Industrial quality “DIY quality" Safe working: All abrasive materials supplied by the Hoffmann Group are certified to: QS Association for safety and quality: The oSa mark warrants fully-inspected manufacture and fulfilment of the strictest grinding tool safety requirements in the world, together with 100% traceability. Rough abrasive discs Grit, bonding, abrasive additives as well as reinforcement of the rough grinding discs are optimised for maximum metal removal rate and working life in their respective applications. Rough grinding discs, depressed centres (shapes 27,28,29). Grinding angle 20° to 30°. For use with electric and pneumatic angle grinders with maximum 80 m/s circumferential speed for grinding welds, surfaces and edges.
