3M 7100189033 Abrasive Belt 156x4 Inch P220 Silicon Carbide

Product Description

The 3M 7100189033 is a silicon carbide abrasive cloth belt designed for grinding, blending, deburring, and finishing operations on metal surfaces. At 156 inches long and 4 inches wide with a P220 grit rating, this belt delivers a fine, consistent finish across its full service life. The silicon carbide mineral fractures readily during use, continuously exposing fresh cutting edges that maintain cut rate and surface quality. A heat-resistant resin bond locks the abrasive to a tough polyester cloth backing, giving the belt the durability and flexibility needed for demanding backstand applications.

This belt is suited for finishing and blending operations on ferrous and non-ferrous metals in fabrication shops, manufacturing facilities, and maintenance environments. The polyester cloth backing is water-resistant, making it appropriate for both wet and dry grinding setups. Typical applications include weld blending, scale removal, deburring, and fine finishing passes where a uniform surface profile is required. Licensed trades and production grinders running backstands or wide-belt finishing equipment will find this belt sized for high-output applications.

Key Features

• Silicon carbide abrasive fractures consistently for sustained cut rate and uniform finish at P220 grit
• Water-resistant polyester cloth backing supports wet and dry use without tearing or nicking
• Heat-resistant resin bond holds abrasive securely under pressure, heat, and moisture
• Flexible cloth construction conforms to contours during blending and finishing passes
• Designed for use on backstands in grinding and finishing applications

Compatibility

Designed for use on backstand grinders and wide-belt finishing equipment that accept a 156-inch by 4-inch abrasive belt. Suitable for grinding and finishing all metals in wet or dry configurations.

Installation Notes

Installation should be performed by qualified personnel familiar with abrasive belt equipment. Power down and de-energize the machine before mounting or removing the belt. Verify belt tracking and tension according to the equipment manufacturer guidelines before resuming operation. Wear appropriate PPE including eye protection and gloves when handling and operating abrasive belts.
