3M 7100099303 Quick Change Fibre Disc 36 Grit 7 Inch

Product Description

The 3M 7100099303 is a 7-inch Quick Change fibre disc designed for aggressive material removal on carbon steel. Built on a stiff fiber backing with a strong resin bond, it uses 3M Precision Shaped Grain technology to deliver higher cut rates and longer service life compared to conventional abrasive discs. Rated at 8600 RPM, this 36-grit disc handles demanding grinding tasks including weld removal, beveling, edge chamfering, blending, and finish refinement. It is intended for use by metal fabricators, welders, and maintenance professionals working with angle grinders or disc grinders equipped with compatible Quick Change pads.

This disc is well suited for heavy industrial and fabrication environments where rapid stock removal on carbon steel is required. Typical applications include weld grinding, surface blending, and edge preparation on structural steel components. The 36-grit cut level makes it appropriate for rough stock removal and weld seam cleanup rather than fine finishing passes. Disc pad face plates and hubs compatible with this Quick Change design are sold separately.

Key Features

• 3M Precision Shaped Grain delivers higher cut rates and more parts per disc than conventional fiber discs
• 36-grit abrasive engineered for aggressive weld removal, beveling, and edge chamfering on carbon steel
• Stiff fiber backing and strong resin bond provide durability and resistance to tearing under load
• 8600 RPM maximum speed rating suits standard angle grinder applications
• Quick Change attachment design allows fast disc swaps without additional tooling
• Long-lasting abrasive mineral helps reduce per-part abrasive cost on high-volume jobs

Compatibility

Compatible with 3M disc pad face plates and hubs designed for the Quick Change system, sold separately. Verify that the grinder and pad assembly are rated at or above 8600 RPM before use.

Installation Notes

Installation and disc changes should be performed by qualified personnel with the grinder powered off and disconnected from its power source. Confirm the disc pad face plate and hub are rated for the disc diameter and RPM before mounting. Inspect the disc for damage before each use and do not use a disc that is cracked, torn, or delaminated. Follow all applicable ANSI B7.1 and grinder manufacturer safety guidelines when operating high-speed abrasive discs.
