Norton 66261054184 Quick-change Disc 2in Silicon Carbide

Product Description

The NORTON 66261054184 is a Type III quick-change abrasive disc from the Merit Deburr/Blend series, designed for surface blending, deburring, and finishing across a wide range of materials. The disc measures 2 inches in diameter and 0.25 inches in height, uses silicon carbide grain bonded to a non-woven backing, and carries a fine grade rating. It attaches via a Type R quick-change system, making tool-free disc swaps fast during production work. Maximum operating speed is 22,000 RPM. Licensed HVAC, metalworking, and fabrication professionals use this disc where a consistent, smear-free scratch pattern is required on non-ferrous metals, ferrous metals, and wood-based substrates.

This disc is suited for deburring and blending operations on aluminum, brass, bronze, cast iron, copper, ductile iron, gray iron, hard woods, soft woods, drywall, ceramic, and glass. It is intended for use with die grinders, handheld disc sanders, inline grinders, and straight grinders in both shop and field environments. The fine grit and resin bond formula make it a practical choice when surface finish quality matters, particularly on non-ferrous metals where smearing is a concern. Sold as a single disc with a minimum order quantity of 60 units.

Key Features

• Silicon carbide grain delivers faster blending and a brighter scratch pattern than aluminum oxide alternatives
• Resin bond formula resists smearing on non-ferrous metals including aluminum, brass, and copper
• Type R quick-change attachment system allows rapid disc changes without additional hardware
• Non-woven backing provides consistent cut and finish throughout the disc life
• Rated to 22,000 RPM for compatibility with standard die grinders and inline grinders
• Fine grade suitable for final-stage surface blending and light deburring

Compatibility

Compatible with die grinders, handheld disc sanders, inline grinders, and straight grinders equipped with a Type R quick-change arbor. Suitable for use on aluminum, brass, bronze, cast iron, copper, ductile iron, gray iron, hard woods, soft woods, drywall, ceramic, and glass.

Installation Notes

Installation is performed by a machinist, fabricator, or maintenance technician using a die grinder or compatible straight grinder fitted with a Type R quick-change mandrel. Verify the tool spindle speed does not exceed the 22,000 RPM disc rating before mounting. Always inspect the disc for damage before use and ensure the quick-change button is fully seated and locked prior to operation. Follow ANSI B7.1 and applicable shop safety guidelines for abrasive disc use, including the use of appropriate eye and face protection.
