Merit Abrasives 69957399768 Quick-change Disc 120 Grit

Product Description

The MERIT ABRASIVES 69957399768 is a 1.5-inch quick-change abrasive disc designed for handheld disc sanders in metalworking and fabrication environments. It runs at a maximum of 30,000 RPM and uses aluminum oxide abrasive on a Y-weight 2-ply polyester backing rated X-weight, giving it a rigid, durable profile suited for aggressive stock removal and fine finishing. The 120-grit fine grade balances cut rate with surface finish, making it a practical choice for deburring, cleaning, and detailing operations. The Power-Lock Type 1 (TP/Type P) attachment system allows fast disc changes without tools. Licensed metalworkers, pipefitters, and fabrication technicians are the primary installers of this disc in production and field environments.

This disc is rated for use on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It is compatible with handheld disc sanders that accept Power-Lock Type 1 quick-change attachments. The coated brown disc is packaged individually but sold in multiples of 100, making it well suited to high-turnover production shops, maintenance facilities, and fabrication operations where consistent abrasive replenishment is part of normal workflow.

Installation Notes

Metalworkers and fabricators should confirm the sander spindle accepts the Power-Lock Type 1 attachment before mounting. Always verify the tool RPM rating does not exceed the 30,000 RPM maximum disc rating prior to use. Inspect the disc for damage or delamination before each use and discard any disc showing signs of wear beyond the abrasive layer. Follow applicable ANSI B7 abrasive product safety standards and wear appropriate PPE including eye and face protection during operation.
