3M 7100178215 Quick Change Fibre Disc 60 Grit 4.5 Inches

Product Description

The 3M 7100178215 is a quick-change coated fibre disc engineered for high-speed material removal on carbon steel. Built on a stiff fiber backing with a strong resin bond, this disc uses 3M Precision Shaped Grain technology to deliver cut rates significantly higher than conventional abrasive discs. At 4.5 inches in diameter and 60 grit, it is suited for heavy-duty grinding, weld removal, beveling, and edge chamfering. Licensed HVAC techs, fabricators, and trade professionals working with carbon steel will find this disc handles demanding stock-removal tasks while outlasting standard fibre discs.

This disc is designed for use in industrial and trade environments where rapid cutting and durability are required. Typical applications include weld grinding, blending, beveling, edge chamfering, and surface finish refinement on carbon steel workpieces. The quick-change attachment system speeds up disc swaps, reducing downtime during high-volume work. It is compatible with 3M disc pad face plates and hubs, which are sold separately.

Compatibility

Compatible with 3M disc pad face plates and hubs sold separately. Designed for use on carbon steel in applications requiring aggressive cut and surface blending.

Installation Notes

This disc is installed by grinding professionals and trade workers using angle grinders fitted with appropriate 3M quick-change backing pads. Ensure the grinder is powered off and disconnected from its power source before mounting or removing any abrasive disc. Inspect the disc for damage before each use and do not exceed the maximum RPM rating of the disc or the grinder. Follow applicable ANSI B11 and OSHA abrasive wheel safety standards during installation and operation.
