Merit Abrasives 69957399708 Quick-change Disc 50 Grit 2in

Product Description

The MERIT ABRASIVES 69957399708 is a coated quick-change abrasive disc built for handheld disc sanders in demanding trade and fabrication environments. It uses aluminum oxide abrasive grain bonded to a rigid, X-weight two-ply cloth and polyester backing — a construction that holds up under aggressive deburring, surface cleaning, and detailing work. The disc measures 2 inches in diameter, runs a coarse 50 grit, and is rated to a maximum of 30,000 RPM. The Power-Lock Type 3 (TR/Type III) attachment system provides fast, secure disc changes without tools, keeping downtime low during production runs.

This disc is suited for deburring, cleaning, and detailing on a wide range of metals including 300 and 400 series stainless steel, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. The rigid backing and coarse grit make it well matched to material removal tasks where a flexible disc would deflect. It is intended for use with handheld disc sanders that accept TR (Type III) or Type R quick-change attachments, common in metal fabrication shops, welding operations, and maintenance environments.

Installation Notes

Installation is performed by metal fabricators, welders, and maintenance technicians using compatible handheld disc sanders. Confirm the tool spindle accepts TR (Type III) or Type R quick-change attachments before mounting. Always verify the tool's maximum RPM rating meets or exceeds 30,000 RPM before use, and ensure the disc is fully seated and locked before powering on. Wear appropriate PPE including eye protection and gloves during disc changes and operation.
