3M 7100099259 Quick Change Fiber Disc 60 Grit 5 Inch

Product Description

The 3M 7100099259 is a 5-inch Quick Change fiber disc built for aggressive material removal on hard-to-grind metals. It uses 3M Precision Shaped Grain, a ceramic abrasive mineral engineered to cut faster and run cooler than conventional fiber disc abrasives. Rated at 12000 RPM and specified at 60 grit, this disc is designed for heavy-duty weld removal, blending, beveling, and edge chamfering on stainless steel and high-nickel alloys. A built-in grinding aid reduces heat buildup, protecting heat-sensitive base materials during extended grinding sessions. Licensed tradespeople and fabrication shop technicians are the primary users.

This disc is suited for metalworking applications where surface heat and disc wear are primary concerns. It performs best on stainless steel and high-nickel alloy workpieces in both shop and field fabrication environments. Typical tasks include weld grinding, bevel prep, and finish blending where surface integrity matters. The stiff fiber backing and strong resin bond resist tearing under load, making the disc viable for sustained use in production settings. It attaches via a Quick Change interface and requires a compatible disc pad face plate or hub, sold separately.

Key Features

• 3M Precision Shaped Grain delivers higher cut rates and cooler grinding versus conventional abrasives
• 60 grit stock removal rating suitable for weld grinding, beveling, and edge chamfering
• Built-in grinding aid minimizes heat generation on stainless steel and high-nickel alloys
• Stiff fiber backing and high-strength resin bond provide tear resistance under heavy load
• Quick Change mount for fast disc swaps without additional tooling
• 5-inch diameter at 12000 RPM maximum operating speed

Compatibility

Compatible with 3M disc pad face plates and hubs designed for the Quick Change interface, sold separately. Designed for use on stainless steel and high-nickel alloy workpieces in weld grinding and blending applications.

Installation Notes

This disc must be installed and operated by qualified personnel familiar with angle grinder safety and abrasive disc handling. Always verify the grinder free speed does not exceed the 12000 RPM disc rating before mounting. Inspect the disc for damage before each use and discard any disc that shows cracks, tears, or delamination. Follow ANSI B7.1 and applicable shop safety standards when operating grinding equipment.
