Norton 66623313920 Quick-change Disc 1 in Ceramic Alumina

Product Description

The NORTON 66623313920 is a 1-inch diameter quick-change abrasive disc in the Bear-Tex Blaze Rapid Blend series. It uses Norton Blaze SG ceramic alumina grain on a flexible non-woven backing, rated for up to 35,000 RPM. The disc attaches via a Type S quick-change system, making it compatible with handheld disc sanders and straight grinders. Graded extra coarse, it delivers an aggressive cut rate and is engineered to resist grain shedding during extended use. Licensed tradespeople and metalworkers in fabrication, finishing, and maintenance environments rely on this disc for rapid material removal and surface blending.

This disc is well suited for deburring, blending, and light finishing on a range of metal substrates. Documented compatible materials include 300 Series Stainless, 400 Series Stainless, Aluminum, Brass, Bronze, Hard Carbon Steels, Soft Carbon Steels, and Titanium. It fits standard handheld disc sanders and straight grinders equipped with a Type S quick-change arbor. The 1-inch diameter makes it practical for tight spots, tube interiors, and small-radius contours that larger discs cannot reach. The orange non-woven construction conforms to irregular surfaces without loading.

Installation Notes

Installation and disc changes should be performed by a qualified operator with the grinder powered off and unplugged or air supply disconnected. Verify the spindle speed rating of the tool does not exceed the 35,000 RPM maximum disc rating before mounting. Inspect the disc for damage before each use and do not use a disc that shows tears, delamination, or missing backing material. Follow applicable ANSI B7.1 and tool manufacturer guidelines for abrasive disc mounting and guard requirements.
