3M 7100189044 Abrasive Belt 138x4 Inch P180 Silicon Carbide

Product Description

The 3M 7100189044 is a silicon carbide cloth abrasive belt designed for grinding, blending, deburring, and finishing on metal surfaces. The sharp silicon carbide mineral fractures consistently during use, maintaining a fresh cutting edge throughout the belt life and producing a uniform finish from start to finish. A heat-resistant resin bond locks the abrasive to the backing, holding up under sustained pressure, heat, and wet conditions. The tough polyester backing is water-resistant, supporting both wet and dry applications without tearing or nicking. At 138 inches long and 4 inches wide with a P180 grit rating, this belt suits backstand grinding and finishing operations in fabrication and metalworking environments.

This belt is suited for professional metalworking and fabrication shops where consistent surface finishing results are required across production runs. It performs well on ferrous and non-ferrous metals in both wet and dry setups. The P180 grit makes it appropriate for intermediate to fine finishing stages, blending weld seams, or deburring machined parts. The cloth backing provides the flexibility needed to conform to contoured workpieces on backstand equipment.

• Water-resistant polyester backing supports wet and dry applications without tearing or nicking
• Flexible cloth construction conforms to contoured workpieces
• Sized for backstand use at 138 inches long by 4 inches wide
• P180 grit rating suits intermediate to fine finishing, blending, and deburring

Compatibility

Designed for use on backstand grinders and finishing equipment that accept 138-inch by 4-inch abrasive belts in metalworking and fabrication applications.

Installation Notes

Belt installation and replacement should be performed by qualified personnel familiar with abrasive belt equipment. Power down and de-energize the backstand grinder completely before changing belts. Confirm belt tracking and tension per the equipment manufacturer guidelines before resuming operation. Always wear appropriate PPE, including eye protection, when operating abrasive belt equipment.
