3M 7100029134 Cubitron Ii 947A Abrasive Belt 120 Grit

Product Description

The 3M 7100029134 is a coated abrasive belt from the Cubitron II 947A line, engineered for aggressive material removal on metal workpieces. It uses 3M Precision-Shaped Grain technology, which slices through metal rather than gouging, resulting in faster cuts, lower grinding temperatures, and a longer-lasting abrasive surface compared to conventional ceramic belts. The belt measures 18 inches long by 1/2 inch wide and carries a 120-grit rating. A grinding aid is incorporated into the construction to reduce friction and keep cutting temperatures down. The X-weight poly-cotton backing adds the flexibility needed for contour and detail work.

This belt is designed for low to medium pressure grinding and finishing applications on stainless steel, mild steels, and aluminum. It is well suited for weld blending, deburring, and surface preparation tasks in fabrication shops, maintenance environments, and light manufacturing settings. Metalworkers and fabricators handling both production runs and precision finishing work will find the cooler cutting action particularly useful when heat-related workpiece damage is a concern.

Key Features

• Precision-Shaped Grain slices metal cleanly rather than plowing, reducing heat buildup
• Removes material faster with less applied pressure compared to conventional ceramic belts
• Integrated grinding aid reduces friction for cooler cutting action
• X-weight poly-cotton backing provides flexibility for contour and irregular surface work
• Optimized for stainless steel, mild steels, and aluminum
• Longer service life reduces belt change frequency on production lines

Compatibility

Designed for use on belt grinders and finishing machines that accept 18-inch by 1/2-inch abrasive belts, for low and medium pressure applications on stainless steel, mild steels, and aluminum.

Installation Notes

Belt installation should be performed by a qualified operator with the machine fully powered down and locked out per applicable OSHA lockout/tagout procedures. Confirm belt tracking and tension according to the machine manufacturer's guidelines before resuming operation. Inspect the belt for tears or edge damage before each use and replace immediately if defects are found.
