3M 7000119163 Fiber Disc 7 in 36 Grit Ceramic Extra Coarse

Product Description

The 3M 7000119163 is a 7-inch ceramic fiber disc designed for aggressive material removal on metal surfaces. Built around premium ceramic alumina abrasive bonded to a fiber backing with a resinoid bond, this disc delivers consistent cut rate and durability under high-pressure grinding applications. At 36 grit, it falls in the extra coarse grade range, making it well suited for rapid stock removal, weld seam cleanup, and edge chamfering. The threaded arbor hole accepts a 5/8-11 center hub and is compatible with the 3M GL Quick Change Backup Pad. Licensed tradespeople in fabrication, welding, and metal finishing are the primary installers of this disc.

This fiber disc is used in industrial and commercial metalworking environments where fast, controlled material removal is required. Typical applications include edge chamfering on structural steel, weld removal on fabricated assemblies, and general stock removal on ferrous and non-ferrous substrates. The maroon disc color is characteristic of the 3M 982C series. It mounts via a threaded arbor hole and is rated for use with compatible angle grinders and disc sanders operating within the specified RPM range.

Key Features

• Resinoid bond holds abrasive grain firmly under aggressive grinding pressure
• Fiber backing provides rigidity and resistance to tearing during heavy use
• 5/8-11 threaded arbor hole for secure attachment to standard backup pads
• Compatible with 3M GL Quick Change Backup Pad for fast disc changes

Compatibility

Designed for use with the 3M GL Quick Change Backup Pad. Fits angle grinders and disc sanders equipped with a 5/8-11 threaded arbor. Verify that the tool spindle speed does not exceed the disc maximum RPM rating before mounting.

Installation Notes

Installation should be performed by a qualified operator familiar with angle grinder safety and applicable ANSI B7 abrasive product standards. Power down and disconnect the grinder from its power source before mounting or removing the disc. Confirm the backup pad and spindle are in good condition and that the tool RPM does not exceed the disc maximum rating of 8,600 RPM. Always wear appropriate PPE including eye protection and gloves when operating grinding equipment.
