3M 7100104898 Coated Fiber Disc 60 Grit 4 Inch

Product Description

The 3M 7100104898 is a coated fiber disc engineered for high-speed material removal on hard-to-grind metals. It uses 3M Precision Shaped Grain, a ceramic abrasive geometry that delivers higher cut rates and cooler grinding temperatures compared to conventional fiber discs. At 4 inches in diameter and 60 grit, this disc is suited for heavy stock removal tasks including weld grinding, beveling, blending, and edge chamfering. A built-in grinding aid further reduces heat buildup, making it appropriate for heat-sensitive alloys. Licensed tradespeople and fabrication shops working with stainless steel and high nickel alloys will find consistent performance across the disc's service life.

This disc is designed for use in metal fabrication and finishing environments where stainless steel and high nickel alloys are the primary workpieces. Typical applications include weld removal, bevel grinding, and surface blending on structural components, pipe, and sheet metal. The stiff fiber backing and strong resin bond resist tearing under aggressive load conditions. It is compatible with standard disc pad face plates and hubs sold separately. Suitable for both shop and field use by fabricators, welders, and metal finishing technicians.

Key Features

• Precision Shaped Ceramic Grain for higher cut rates and cooler grinding temperatures
• Built-in grinding aid minimizes heat on stainless steel and high nickel alloys
• Stiff fiber backing with strong resin bond resists tearing under heavy load
• 60 grit rating suited for aggressive stock removal, weld grinding, and beveling
• Compatible with 3M disc pad face plates and hubs (sold separately)
• Long service life helps lower cost per part compared to conventional fiber discs

Compatibility

Compatible with 3M disc pad face plates and hubs sold separately. Designed for use on stainless steel and high nickel alloys in weld grinding, blending, and finish refinement applications.

Installation Notes

Mount the disc securely to the appropriate backing pad and hub before use. Verify that the grinder speed rating does not exceed the disc's maximum rated RPM. Wear appropriate PPE including eye protection and gloves when operating angle grinders. Inspect the disc for damage before each use and replace if tears, cracks, or excessive wear are present.
