3M 7100099033 Quick Change Fibre Disc 36 Grit 4.5 in

Product Description

The 3M 7100099033 is a 4.5-inch Quick Change 782C coated fibre disc designed for rapid stock removal on carbon steel. It uses 3M Precision Shaped Grain, an advanced abrasive geometry that cuts faster and lasts longer than conventional alumina oxide grains. At 36 grit, this disc is built for aggressive material removal tasks including weld grinding, beveling, and edge chamfering. A stiff fibre backing paired with a strong resin bond gives the disc the rigidity and tear-resistance needed to hold up under sustained pressure. Licensed HVAC, fabrication, and metalworking tradespeople rely on this disc for consistent, repeatable results across high-volume work.

This disc is suited for heavy-duty carbon steel grinding applications in fabrication shops, field welding operations, and structural metalwork environments. Typical use cases include weld removal, surface blending, and finish refinement on flat and curved carbon steel workpieces. The Quick Change attachment system allows for fast disc swaps without tools, reducing downtime during production runs. It is compatible with 3M disc pad face plates and hubs sold separately.

Key Features

• 3M Precision Shaped Grain delivers higher cut rates and more parts per disc compared to conventional fibre discs
• 36 grit aggression suits weld removal, beveling, edge chamfering, and heavy blending
• Stiff fibre backing and strong resin bond provide rigidity and tear-resistance under load
• Quick Change attachment allows tool-free disc replacement for reduced downtime
• Long-lasting abrasive mineral reduces per-part consumable cost over a production run
• Compatible with 3M disc pad face plates and hubs sold separately

Compatibility

Compatible with 3M disc pad face plates and hubs sold separately. Designed for use on carbon steel in grinding and finishing applications.

Installation Notes

This disc is installed and serviced by metalworkers, fabricators, and welding tradespeople. Before mounting, confirm the grinder is rated for the disc diameter and that the arbor speed does not exceed the disc's maximum rated RPM. Power down and disconnect the grinder before changing discs. Inspect the disc for cracks or damage before each use and do not use a damaged disc.
