3M 7100141690 Abrasive Belt 80 Grit 24x0.25 Inch Cubitron Ii

Product Description

The 3M 7100141690 is a coated abrasive belt from the Cubitron II 947A series, built around 3M Precision-Shaped Grain technology. Unlike conventional ceramic abrasives that gouge or plow through material, the triangular grain structure slices metal with a consistent cutting edge. The result is faster material removal at lower applied pressure, with significantly less heat generation at the workpiece. The belt measures 24 inches in length and 0.25 inches in width. An X-weight poly-cotton backing delivers the flexibility needed for contour and detail grinding work. Grit is 80, suited for moderate stock removal on metal surfaces. Licensed HVAC, fabrication, and metalworking professionals handling stainless steel, mild steel, or aluminum grinding tasks will find this belt well-suited to production and service environments.

This belt is designed for low to medium pressure grinding and finishing applications on stainless steel, mild steels, and aluminum. The 947A designation indicates a belt optimized for those metal types where heat buildup and surface discoloration are concerns. The narrow 0.25-inch width makes it appropriate for file belt tools, detail grinders, and narrow contact wheel setups used in weld blending, deburring, and pipe or tube finishing operations common in mechanical and fabrication trades.

Key Features

• Precision-Shaped Grain slices metal rather than gouging, improving cut rate and reducing heat
• Optimized for low and medium pressure applications on stainless steel, mild steel, and aluminum
• Includes a built-in grinding aid that reduces friction and keeps cutting temperatures low
• X-weight poly-cotton backing provides flexibility for contour and narrow-contact grinding
• 80 grit provides efficient stock removal on metal workpieces
• Designed to outlast conventional ceramic abrasive belts in extended grinding cycles

Compatibility

Designed as a coated abrasive replacement belt for narrow file belt tools and detail grinders accepting a 24-inch length by 0.25-inch width belt configuration.

Installation Notes

Belt installation should be performed by qualified personnel following the tool manufacturer's instructions for belt tensioning and tracking adjustment. Ensure the power tool is fully de-energized and unplugged before changing the belt. Inspect the contact wheel or platen for wear before mounting a new belt, as surface irregularities can cause premature belt failure. Appropriate PPE including eye protection and gloves should be worn during installation and operation per applicable workplace safety standards.
