Merit Abrasives 08834167100 Quick-change Disc 36 Grit

Product Description

The MERIT ABRASIVES 08834167100 is a quick-change coated abrasive disc designed for rapid material removal on metal surfaces. It uses a zirconia alumina abrasive grain bonded to a cloth backing, delivering aggressive cutting action at 36 grit (very coarse grade). The disc measures 1.5 inches in diameter and is rated to 30,000 RPM. It attaches via a Type R power-lock system, allowing tool-free disc changes on compatible right-angle grinders and die grinders. The blue cloth backing carries a Y-weight designation, indicating a stiff, durable substrate suited for heavy stock removal and weld blending applications.

This disc is used in metal fabrication, weld prep, and surface conditioning tasks where fast, aggressive cutting is required. At 1.5 inches, it fits compact die grinders and right-angle tools used in tight-access areas such as tube interiors, pipe joints, and structural steel connections. The Type R attachment system is common in production grinding and maintenance environments where disc changes must be completed quickly to minimize downtime. The flexible cloth backing conforms slightly to contoured workpieces without sacrificing cutting aggressiveness.

Installation Notes

Installation and disc changes should be performed with the grinder unplugged or the air supply disconnected. Verify the mandrel and spindle are rated to at least 30,000 RPM before mounting the disc. Confirm the workpiece is secure and all guards are in place before operating. Inspect the disc for damage before each use and discard any disc that shows cracks, tears, or delamination.
