Merit Abrasives 08834160458 3 in 36 Grit Ceramic Disc

Product Description

The MERIT ABRASIVES 08834160458 is a 3-inch quick-change abrasive disc designed for aggressive stock removal and surface finishing on metal. It uses a ceramic alumina blend with a self-lubricating treatment that cuts fast, generates less heat, and extends disc life compared to standard aluminum oxide. The Y-weight polyester backing provides heavy-duty durability under sustained grinding pressure. Rated at 20,000 RPM, this disc mounts via a Type R Power-Lock attachment system and is suited for handheld disc sanders used in professional fabrication, maintenance, and welding shops. Sold individually, minimum order quantity is 50 units.

This disc is engineered for use on 300 series stainless steel, 400 series stainless steel, cast iron, and soft carbon steels. The 36 grit extra coarse grade makes it well suited for weld blending, deburring, and rapid stock removal where surface finish is secondary to material takedown rate. It performs well in high-contact-pressure applications common in metal fabrication and industrial maintenance. The red disc color and black button are part of the SG R981 series product identification system.

Installation Notes

Installation should be performed by a trained operator familiar with abrasive disc safety requirements. Verify that the spindle speed of the tool does not exceed the 20,000 RPM maximum disc rating before mounting. Inspect the disc for damage before each use and discard any cracked or delaminated discs. Always wear appropriate eye and face protection when operating grinding equipment, and ensure all guards are in place per applicable ANSI and OSHA requirements.
