Norton 08834164502 Quick-change Disc 3in 80 Grit Aluminum Oxide

Product Description

The NORTON 08834164502 is a TR (Type III) quick-change coated abrasive disc designed for aggressive material removal on metal surfaces. It measures 3 inches in diameter and carries an 80-grit aluminum oxide abrasive, placing it in the coarse grade range. The disc features a Y-weight 2-ply polyester cloth backing that adds structural rigidity and extends service life. A coated construction delivers a faster cut rate compared to standard single-layer discs. This disc mounts via a Type R attaching system and is rated to 20,000 RPM. It is installed and used by metal fabricators, maintenance mechanics, and trade professionals working with handheld disc sanders.

This disc is suited for deburring, surface cleaning, and detailing operations on a range of ferrous and non-ferrous metals. Verified material applications include 300 Series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It is intended for use with handheld disc sanders equipped with a TR or Type R quick-change hub. The coarse 80-grit cut makes it appropriate for initial stock removal, weld cleanup, and surface prep before finishing operations. Sold individually, it fits into standard disc rotation schedules on production and field service work.

Disconnect or power down the tool before changing discs. Inspect the disc for cracks or damage before each use and do not use damaged discs. Follow applicable ANSI B7 and OSHA abrasive wheel safety standards when operating grinding and sanding equipment.
