Norton 662611-29718 Avos Speed Lok Disc 4.5 in 24 Grit

Product Description

The NORTON 662611-29718 is an Avos Speed Lok Plus abrasive disc engineered for aggressive material removal on stainless steel and metal alloys. The disc measures 4.5 inches in diameter and uses a 24-grit Zirconia Alumina abrasive, a self-sharpening grain that maintains cut rate under load and extends disc life compared to standard aluminum oxide. The Speed Lok attachment system allows fast, tool-free disc changes on compatible right-angle grinders. Sold in boxes of 10, this disc is a production-grade consumable suited for fabrication shops, pipe welders, and field service technicians who need consistent stock removal on hard-to-grind materials.

This disc is designed for use on stainless steel and high-alloy materials where contamination control and cut performance are both priorities. Typical applications include weld blending, surface prep, and deburring in structural fabrication, industrial maintenance, and pipefitting environments. The 24-grit designation makes it appropriate for heavy stock removal rather than finishing passes. It is used with right-angle grinders fitted with a Speed Lok hub or backing pad.

Installation Notes

This disc is installed and replaced by grinding technicians, fabricators, or pipe welders using compatible Speed Lok-equipped grinders. Always power down and disconnect the grinder from its power source before changing discs. Inspect the disc for cracks or damage before each use and never exceed the maximum RPM rating marked on the disc. Personal protective equipment including a face shield, gloves, and hearing protection is required during operation per standard grinding safety practice.
