Norton NRT66261043392 Ceramic Abrasive Disc 3 in 120 Grit

Product Description

The NORTON NRT66261043392 is a 3-inch, 120-grit abrasive disc built around Norton SG ceramic alumina grain. The SG grain structure is engineered to fracture at a controlled rate, continuously exposing fresh cutting edges throughout the life of the disc. A self-lubricating supersize treatment reduces heat buildup at the workpiece, allowing faster material removal with less surface discoloration and lower risk of thermal damage. These characteristics make the disc well-suited for precision grinding and finishing operations where maintaining workpiece integrity is as important as cut rate. Licensed trade professionals and fabricators working in metal finishing, weld blending, and surface preparation will find this disc performs consistently from first contact to end of disc life.

This disc is intended for use on angle grinders and disc grinders in both shop and field environments. The 120-grit rating positions it for intermediate to fine finishing work, including deburring, surface conditioning, and final blending passes on ferrous and non-ferrous metals. It is sold in box quantities, making it practical for ongoing shop stock. Typical applications include structural steel fabrication, weld seam finishing, and general metal surface prep in manufacturing or mechanical service settings.

Key Features

• Norton SG ceramic alumina grain fractures progressively for consistent cut rate over the full disc life
• Self-lubricating supersize treatment dissipates heat at the contact zone, reducing burn risk on workpieces
• 120-grit rating suited for intermediate finishing, deburring, and weld blending
• 3-inch disc diameter fits standard angle grinders and disc grinder pads
• Sold by the box with a minimum order quantity of one box

Compatibility

Designed for use with 3-inch disc grinders and angle grinders that accept standard 3-inch abrasive discs. No specific equipment model compatibility data was provided; verify arbor size and grinder RPM rating against disc specifications before use.

Installation Notes

Disc mounting and grinder operation should be performed by a qualified operator familiar with abrasive safety standards, including ANSI B11.9 and applicable OSHA regulations. Always power down and unplug the grinder before mounting or removing a disc. Inspect the disc for cracks or damage before each use and never exceed the maximum RPM rating marked on the disc or packaging. Wear appropriate PPE including face shield, gloves, and hearing protection during operation.
