4-1/2″*7/8″Inch 115*22.23mm High Quality Consistent Even Grinding Action Polishing Disc
Product Overview
The 4.5″ (115mm) high-performance non-woven disc features a 7/8″ arbor for secure mounting on standard grinders. Infused with silicon carbide, it tackles tough coatings and hard metals with precision. The reinforced fiber matrix prevents unraveling during high-RPM use, while its medium-to-fine grit range (80–320) adapts to multi-stage finishing. Industries favor this disc for its balance of aggressiveness and finish quality.
