Merit Abrasives 69957399769 Quick-change Disc 150 Grit

Product Description

The MERIT ABRASIVES 69957399769 is a coated quick-change abrasive disc designed for use with Power-Lock Type 1 (Type P) attachment systems on handheld disc sanders. It measures 1.5 inches in diameter and runs at a maximum of 30,000 RPM. The abrasive material is aluminum oxide bonded to a rigid X-weight 2-ply polyester backing, providing a durable platform for consistent stock removal. At 150 grit, this disc falls in the very fine range, making it well suited for deburring, cleaning, and surface detailing on ferrous and non-ferrous metals. Licensed trades and fabrication shops keep these on hand for finish-pass work where a coarser disc would leave unacceptable scratch patterns.

This disc is designed for metalworking applications on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It is intended for use with a handheld disc sander equipped with a Power-Lock Type 1 quick-change arbor. The small 1.5-inch diameter makes it practical for tight geometries, weld seam cleanup, and edge detailing where larger discs cannot reach. It is sold individually but carries a minimum order quantity of 100 units, making it appropriate for shop stocking rather than single-use purchase.

Installation Notes

Metalworkers and fabricators should verify the tool spindle carries a compatible Power-Lock Type 1 quick-change arbor before mounting this disc. Confirm the tool's rated free speed does not exceed 30,000 RPM prior to use. Inspect the disc for damage before each use and discard any disc showing cracks, tears, or delamination. Always wear appropriate PPE including eye protection and gloves when operating abrasive discs.
