3M 7100405671 Cloth Abrasive Belt 220+ Grit 2x72 in

Product Description

The 3M 7100405671 is a closed-coat aluminum oxide cloth-backed abrasive belt designed for general-purpose metalworking and light woodworking applications. Measuring 2 inches wide by 72 inches long, it runs on standard belt grinders and finishing machines used in fabrication and shop environments. The XF-weight polyester cloth backing provides flexibility through a single-flex construction, allowing the belt to conform to contoured and flat workpiece surfaces. At 220+ grit, this belt is suited for fine finishing, light deburring, and surface blending passes. The Film-lok splice keeps the joint low-profile and durable under continuous operation. Metalworking professionals, fabricators, and finishing technicians are the primary users of this belt.

This belt is optimized for use on mild steel and carbon steel, and performs effectively on softer metals including aluminum, bronze, and brass. It can be used wet or dry, making it adaptable to both dry grinding setups and coolant-assisted operations. Woodworking applications are also within scope for general finishing work. The closed-coat construction maximizes abrasive surface contact per pass, which improves cut efficiency on metal surfaces and reduces the number of passes needed to achieve a consistent finish.

Key Features

• 220+ grit aluminum oxide abrasive for fine finishing and light deburring on metal and wood
• XF-weight polyester cloth backing resists tearing under load while maintaining flexibility
• Single-flex construction allows the belt to track cleanly on curved and flat contact surfaces
• Closed-coat abrasive layout maximizes surface coverage for consistent material removal
• Film-lok splice provides a low-profile, strong joint that reduces bump and vibration during operation
• Wet or dry rated for use with or without coolant or cutting fluids

Compatibility

Designed for use on standard 2 inch x 72 inch belt grinders and finishing machines. Suitable for mild steel, carbon steel, aluminum, bronze, and brass workpieces, as well as general woodworking finishing applications.

Installation Notes

Install abrasive belts only on machines rated for the belt dimensions and operating speed. Power down and de-energize the belt grinder before changing belts. Confirm belt tracking is properly adjusted before resuming operation to prevent edge wear or belt walk-off. Inspect the Film-lok splice for integrity before each use and remove the belt from service if the splice shows signs of lifting or separation.
