3M 7010359943 Coated Abrasive Belt 40 Grit 118x3/8 in

Product Description

The 3M 7010359943 is a coated abrasive belt designed for demanding stock removal and metal finishing applications. It combines 3M Ceramic Abrasive Grain with aluminum oxide in a blend that cuts faster and lasts longer than conventional aluminum oxide belts. The heavyweight polyester backing handles high-pressure grinding and can be run dry or with a lubricant, making it suitable for a wide range of metalworking conditions. A built-in grinding aid reduces heat buildup during use, which is especially beneficial when working on heat-sensitive metals such as stainless steel. This belt measures 118 inches in length and 3/8 inch in width, with a 40-grit cut rating, and weighs approximately 0.16 pounds.

This belt is used in industrial and trade metalworking environments where consistent stock removal and extended belt life are required. Typical applications include grinding, blending, and finishing on ferrous and non-ferrous metals. It is well suited for fabrication shops, maintenance operations, and production grinding setups. The orange-colored belt is easily identified on the shop floor and is sold individually (each unit).

Key Features

• Ceramic and aluminum oxide grain blend for faster cutting and longer belt life compared to standard aluminum oxide
• Heavyweight polyester backing supports high-pressure applications without premature breakdown
• Run wet or dry for flexibility across different metalworking processes
• Built-in grinding aid reduces heat generation, extending performance on stainless steel and other heat-sensitive metals
• Durable resin bond resists heat deterioration to maximize belt service life
• 40-grit aggressiveness suited for initial stock removal and heavy material blending

Compatibility

Designed as a direct-fit coated abrasive belt for standard belt grinders and finishing machines that accept a 118-inch by 3/8-inch belt configuration.

Installation Notes

Belt installation and replacement should be performed by qualified personnel familiar with abrasive belt equipment. Power down and lock out the grinder before changing the belt. Verify belt tracking and tension according to the machine manufacturer's guidelines before resuming operation. Inspect the belt for tears or damage prior to each use and replace immediately if defects are found.
