Norton 69957370211 Fiber Disc 5 in 60 Grit Ceramic Alumina

Product Description

The NORTON 69957370211 is a 5-inch ceramic alumina fiber disc designed for aggressive material removal on metal, stainless steel, and other hard surfaces. Part of the BlazeX F970 Series, it runs on a threaded arbor hole attachment rated to 10,000 RPM. The resinoid bond holds the ceramic alumina grain firmly through high-heat grinding cycles, extending disc life compared to conventional aluminum oxide. At 60 grit, this disc delivers medium-coarse stock removal suited for weld blending, surface prep, and deburring tasks common in fabrication and maintenance work. Licensed trades and industrial grinder operators are the primary users.

This disc is intended for use with angle grinders equipped with a 5/8-11 threaded arbor and a compatible back-up pad. Norton specifies use with the Norton Speed-Change Back-Up Pad for proper support and vibration control. The 5-inch diameter fits a wide range of standard angle grinders used in metal fabrication shops, construction, and maintenance environments. The orange fiber backing provides structural rigidity under load, making it appropriate for flat and contoured surface grinding at sustained high speeds.

Key Features

• Ceramic alumina abrasive grain for extended cut rate and cooler grinding
• 60 grit medium-coarse grade for weld blending, deburring, and surface prep
• Threaded arbor hole (5/8-11) for secure, tool-free disc changes with Speed-Change system
• Resinoid bond holds grain through high-heat, high-load grinding cycles
• 10,000 RPM maximum rated speed for use with standard angle grinders
• Fiber backing provides rigid support and reduces disc flex under pressure

Compatibility

Designed for use with angle grinders fitted with a 5/8-11 threaded arbor. Norton specifies pairing with the Norton Speed-Change Back-Up Pad for proper backing and support during operation.

Installation Notes

Install and remove this disc only with the grinder unplugged or the power source locked out. Thread the disc onto the 5/8-11 arbor of the appropriate Norton Speed-Change Back-Up Pad until fully seated before mounting the assembly on the grinder. Do not exceed the 10,000 RPM maximum rated speed. Inspect the disc for cracks, chips, or damage before each use and discard any disc showing signs of deterioration.
