Merit Abrasives 69957399750 Quick-change Disc 36 Grit

Product Description

The MERIT ABRASIVES 69957399750 is a Power-Lock Type 1 quick-change abrasive disc engineered for fast stock removal and weld blending on metal surfaces. Built on a Y-weight 2-ply polyester backing, this disc is rigid enough for demanding grinding work while the special grain coating extends cutting life. At 36 grit, it falls in the extra-coarse range, making it well-suited for aggressive material removal. The disc measures 1 inch in diameter and is rated to 40,000 RPM, keeping it compatible with standard handheld disc sanders used in fabrication and metalworking environments. Licensed HVAC techs, metal fabricators, and maintenance pros will recognize this as a reliable consumable for prep work on weld seams and raw stock.

This disc is designed for use with handheld disc sanders and attaches via a Type P attaching system with TP (Type I) quick-change compatibility. Typical applications include surface prep, stock removal, and weld blending across a range of metals. Confirmed compatible materials include 300 Series Stainless, 400 Series Stainless, Aluminum, Brass, Bronze, Hard Carbon Steels, Soft Carbon Steels, and Titanium. It is sold in individual units with a minimum order quantity of 100 pieces, making it appropriate for shop replenishment and fleet stocking.
