3M? 785C Fibre Disc contains a 3M high performance ceramic and aluminium oxide blend abrasive. This blend self sharpens and yields a high cut rate surpassing other conventional discs (Aluminium Oxide) in both performance and longevity. The abrasive is made on a fibre backing thats close-coated and resin bonded.
These discs contain a hard and resistant mineral, superior to aluminium oxide, allowing them to remove a large amount of material.
For metal surfaces including stainless steel, nickel alloy, special steels, brass, bronze, aluminium, etc.
Low heat impact on the mineral and the part being worked on, thus improving the cut.
Increased service life even under high stress.
