| + | * Non-woven disc aggressively deburrs and finishes on all metals. ((https:// | ||
| + | * Grades: coarse, medium, super fine and very fine. | ||
| + | * Combined with Roloc backing, allows for aggressive cutting. | ||
| + | * Open-web construction resists loading and runs cool allowing for consistent finishes. | ||
| + | * 3M™ Roloc™ attachment system offers quick and easy disc change-out for multi-step finishing processes. | ||
| + | * Silicon carbide abrasive: | ||
| + | * Silicon carbide is a synthetic mineral that is very sharp and commonly used for low-pressure applications such as paint prep and finishing. \\ While silicon carbide breaks down faster than aluminum oxide, it produces a finer finish. | ||
| + | * Aluminum oxide abrasive: | ||
| + | * Aluminum oxide is a hard, blocky mineral that provides high cut-rate and long life. | ||
| + | * Mandrel and rubber backing pad are a separate item to the disks. | ||
| + | * Used for deburring, blending, finishing, grinding and surface prep. | ||
| + | * Also can be used to deepen the valve clearance eyebrows in the heads (if required). ((AussieGazza of the XLFORUM https:// | ||
