3M 7100170810 Scotch-brite Non-woven Finishing Belt 75x25 in

Product Description

The 3M 7100170810 is a Scotch-Brite non-woven finishing belt designed for light-pressure finishing applications across metals, whitewood, and composites. Built on a stretch-resistant nylon film backing, the belt stays firm and tracks smoothly on contact-wheel and platen belt grinders. Aluminum oxide abrasive delivers consistent wear resistance and extended service life compared to cork belts, rag wheels, or flap wheels. A built-in lubricant reduces heat buildup and minimizes loading, keeping the surface cleaner through longer runs. The belt measures 75 inches in length and 25 inches in width and weighs 7.831 pounds per unit.

This belt is suited for finishing operations in fabrication shops, woodworking facilities, and metalworking environments where light material removal and surface refinement are the goal. It performs well in place of cork belts, buffing compounds, coated abrasive belts, and bristle brushes. The soft, conformable nonwoven construction follows irregular contours, making it practical for finishing weldments, castings, and shaped wood or composite panels. It is typically run by machinists, fabricators, and finishing technicians on wide-belt sanders or contact-wheel machines.

Key Features

• Aluminum oxide abrasive for increased wear resistance and extended belt life
• Stretch-resistant nylon film backing tracks firmly and runs smooth under load
• Built-in lubricant reduces heat buildup and minimizes abrasive loading
• Soft, conformable nonwoven construction adapts to irregular surface profiles
• Suitable for metals, whitewood sanding, and composite materials
• Replaces cork belts, rag wheels with compounds, coated abrasive belts, and flap wheels

Compatibility

Designed as a direct-use replacement for cork belts, buffing compounds, coated abrasive belts, flap wheels, and bristle brushes on wide-belt contact-wheel finishing machines sized for 75-inch by 25-inch belts.

Installation Notes

Installation should be performed by qualified machine operators or finishing technicians familiar with wide-belt sander and contact-wheel equipment. Confirm the machine is fully powered down and de-energized before mounting or replacing the belt. Verify belt tracking alignment before running at full speed. Follow the equipment manufacturer guidelines for tension and tracking adjustment to avoid premature belt failure or machine damage.
