Norton 69957370202 Ceramic Alumina Fiber Disc 7in 50 Grit

Product Description

The NORTON 69957370202 is a 7-inch ceramic alumina fiber disc designed for aggressive material removal on metal, stainless steel, and weld areas. Part of the BlazeX F970 series, it uses a resinoid bond over a fiber backing to deliver consistent cut rates under load. At 50 grit coarse grade, it removes stock quickly while holding its shape through extended use. The ceramic alumina grain self-sharpens during grinding, reducing heat buildup and extending disc life compared to conventional aluminum oxide. It mounts via a 7/8-inch arbor hole and is rated to 8,600 RPM. Metal fabricators, welders, and industrial maintenance techs are the primary users.

This disc is suited for angle grinder applications in fabrication shops, structural steel work, and maintenance environments where coarse stock removal or weld blending is required. The 50 grit rating makes it effective for removing mill scale, rust, and weld spatter. The fiber backing provides rigidity and resistance to tearing under side-load conditions. It is sold individually, with a minimum order quantity of 25 units per order.

Key Features

• Ceramic alumina grain self-sharpens for sustained cut rate and reduced heat
• 50 grit coarse grade for aggressive stock removal and weld blending
• Fiber backing provides rigidity and tear resistance under load
• Resinoid bond maintains grain adhesion through heavy grinding passes
• 7/8-inch arbor hole fits standard angle grinder backing pads
• 8,600 RPM maximum speed rating

Compatibility

Designed as an OEM-style replacement fiber disc for use with standard 7-inch angle grinder backing pads accepting a 7/8-inch arbor hole attachment.

Installation Notes

Installation is performed by metalworking professionals and industrial maintenance technicians using a compatible angle grinder and 7-inch backing pad. Ensure the grinder is unplugged or its power source is locked out before mounting or removing the disc. Do not exceed the rated maximum speed of 8,600 RPM. Inspect the disc for cracks or damage before each use and discard any disc that shows signs of delamination or backing deterioration.
