Merit Abrasives 69957399784 Quick-change Disc 320 Grit

Product Description

The MERIT ABRASIVES 69957399784 is a 2-inch diameter quick-change coated abrasive disc designed for use with Power-Lock Type 1 attachment systems on handheld disc sanders. Rated at 320 grit and classified as extra fine grade, this aluminum oxide disc is backed by a Y-weight 2-ply polyester backing that is rigid and built for durability. The coated construction provides additional service life and a faster cut rate compared to standard cloth-backed alternatives. It is intended for professional use in metal fabrication, finishing, and surface preparation applications where consistent, controlled material removal is required.

This disc is suited for use on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. Its extra fine 320-grit rating makes it appropriate for deburring, cleaning, and detailing operations rather than aggressive stock removal. It attaches via a Type P system and is compatible with handheld disc sanders. The disc is sold individually but carries a minimum order quantity of 100 units, making it well suited for shop environments that maintain high-volume abrasive inventory. Commercial metal fabrication shops and maintenance facilities are the primary users of this product.
