Norton 69957370205 Ceramic Alumina Fiber Disc 36 Grit

Product Description

The NORTON 69957370205 is a ceramic alumina fiber disc engineered for aggressive material removal on metal, stainless steel, and hard alloys. Part of the BlazeX F970 Series, this disc combines a resinoid bond with a ceramic alumina abrasive grain to deliver fast, consistent stock removal across its service life. It is rated at a maximum of 11,000 RPM and carries a very coarse 36 grit designation, making it well suited for weld grinding, surface prep, and scale removal. The fiber backing provides the rigidity needed to hold the disc flat under pressure. Licensed tradespeople and metal fabricators working in both shop and field environments regularly specify this disc for high-production grinding tasks.

This disc is sized at 4-1/2 inches in diameter with a 5/8-11 threaded arbor hole for use with a threaded arbor backup pad. It attaches via a threaded arbor hole mount and is specifically called out for use with a Norton Speed-Change Back-Up Pad. Typical applications include angle grinder work on structural steel, pipe welds, and fabricated assemblies where rapid material removal is the priority. The orange disc color is a visual identifier for the BlazeX F970 Series product line.

Key Features

• Ceramic alumina abrasive grain for fast cutting and extended disc life under heavy use
• Very coarse 36 grit removes welds, scale, and surface imperfections efficiently
• Resinoid bond holds grain securely during high-pressure grinding applications
• 11,000 RPM maximum speed rating suits standard 4-1/2 inch angle grinders
• 5/8-11 threaded arbor hole for secure, tool-free mounting with compatible backup pads
• Rigid fiber backing maintains disc flatness and reduces flex during use

Compatibility

Designed for use with the Norton Speed-Change Back-Up Pad. Fits angle grinders equipped with a 5/8-11 threaded spindle. Intended for use as a coated abrasive disc in metal grinding and surface preparation applications.

Installation Notes

This disc is installed by a tradesperson or fabricator onto an angle grinder using a compatible 5/8-11 threaded backup pad. Before mounting or changing discs, power down and disconnect the grinder from its power source. Verify that the grinder spindle speed does not exceed the 11,000 RPM disc rating before operation. Inspect the disc for cracks or damage prior to each use and never use a damaged disc.
