Merit Abrasives 69957399693 Quick-change Disc 24 Grit 1.5 in

Product Description

The MERIT ABRASIVES 69957399693 is a coated quick-change abrasive disc designed for aggressive material removal in metal fabrication, weld grinding, and surface preparation applications. Built on a rigid polyester backing with a Y-weight designation, this disc uses aluminum oxide grain bonded to a cloth-backed substrate for consistent cut rate and durability. At 24 grit, it falls in the very coarse grade range, making it well suited for rapid stock removal and weld blending. The disc is rated to 30,000 RPM and mounts via a Type R attaching system compatible with TR (Type III) quick-change holders. Weighing 0.001 pounds per unit, it is sold individually with a minimum order quantity of 100 pieces.

This disc is used in industrial and trade environments where fast, repeatable material removal is required on ferrous and non-ferrous metals. Typical applications include deburring, weld removal, rust stripping, and surface conditioning on steel and similar substrates. It is commonly used by fabricators, pipefitters, and maintenance technicians working with angle grinders or die grinders equipped with compatible quick-change mandrels. The rigid backing provides controlled cut geometry, particularly useful when working on flat or slightly contoured surfaces where disc deflection would reduce efficiency.

Key Features

• 24 grit aluminum oxide grain for very coarse, aggressive stock removal
• Rigid polyester Y-weight backing minimizes disc deflection during use
• Type R attaching system compatible with TR (Type III) quick-change holders
• 30,000 RPM maximum speed rating for use with high-speed die grinders
• 1.5-inch disc diameter suited for tight-access grinding and deburring work
• Brown coated finish consistent with MERIT R766 series abrasive line

Compatibility

Designed for use with TR (Type III) and Type R quick-change mandrels and holders on die grinders and angle grinders accepting 1.5-inch quick-change discs.

Installation Notes

Installation should be performed by qualified technicians familiar with abrasive tooling and applicable ANSI B7 safety standards for abrasive products. Always verify the tool spindle speed does not exceed the disc maximum RPM rating of 30,000 before mounting. Inspect the disc for cracks or damage before each use and discard any disc that shows signs of wear through the backing. Use the appropriate Type R mandrel and ensure the disc is fully seated and locked before operating the grinder.
