3M Ceramic Abrasive Disc 100 mm, P80 Grit, Fibre Backing, 25 Per Pack 89721

3M 89721 Ceramic Abrasive Disc is a high-performance sanding disc designed for industrial and mechanical use with a 100 mm diameter and P80 grit for effective abrasive action.

Made from ceramic abrasive minerals, this disc features a fibre backing combined with a robust resin bond to deliver durability and resistance to wear during heavy grinding tasks. The closed-coat design and precision-shaped grains enable cooler operation and prolonged life, outperforming conventional ceramic fibre discs.

The disc is rated for maximum safe speeds up to 15300 rpm and includes a centre hole of 22.225 mm for secure mounting on angle grinders or sanders, making it suitable for metal fabrication, automotive repair, construction, and marine industries.

This pack contains 25 discs, each delivering consistent performance for welding, deburring, chamfering, and blending metal surfaces.

Typical applications cover carbon steel, stainless steel, and aluminium surfaces, making this abrasive disc suitable for demanding job sites in metalworking and fabrication environments.

The disc's ceramic abrasive material ensures fast, precise material removal with reduced frequency of replacements. Durable fibre backing and resin bond contribute to tear resistance under heavy use. Precision-shaped grain technology maintains sharpness and reduces grinding temperatures, especially on heat-sensitive alloys.

This abrasive disc is optimized for tough welding grind tasks including deburring and surface blending. Ideal for use with 3M backing pads on angle grinders or sanders. Explore our wide selection of Abrasive Discs at EnvMart for all your industrial grinding and finishing needs.
