3M 7100123219 Glass Seaming Belt 461F P80 24x3 Inch

Product Description

The 3M 7100123219 is a coated abrasive belt in the 461F series, engineered specifically for grinding, finishing, and polishing glass and mirror edges. Built on a water-resistant Y-weight polyester cloth backing with resin-bonded silicon carbide mineral, it delivers sharp, consistent cutting action across flat and curved glass surfaces. At P80 grit, it removes material efficiently while leaving a controlled finish suitable for seaming operations. The closed coat construction and anti-friction resin bond help resist heat buildup and extend belt life. Glass fabricators and glaziers rely on this belt for production seaming work where finish consistency is critical.

This belt is sized at 24 inches long by 3 inches wide, making it compatible with standard glass seaming belt grinders used in flat glass fabrication shops and mirror processing operations. It is suited for both wet and dry applications, and the water-resistant backing allows use with liquid lubricants, which is standard practice in glass edge finishing to control heat and debris. Typical applications include straight-line edge grinding, arris finishing, and polishing on architectural glass, mirrors, and decorative glass panels.

Key Features

• Silicon carbide mineral provides sharp cutting action and consistent finish on glass and mirror surfaces
• Closed coat construction delivers uniform material removal and a fine, repeatable surface finish
• Water-resistant Y-weight polyester cloth backing compatible with liquid lubricants for wet grinding
• Anti-friction resin bond resists heat buildup and extends belt service life
• Flexible construction conforms to flat and curved glass edge profiles
• P80 grit rated for efficient stock removal in seaming and edge grinding stages

Compatibility

Designed for use on standard glass seaming belt machines that accept 24-inch by 3-inch abrasive belts, suitable for flat glass, mirrors, and decorative glass edge finishing applications.

Installation Notes

Belt installation and replacement should be performed by qualified glass fabrication technicians familiar with the specific belt grinder in use. Disengage and lock out the machine before removing or mounting the belt. Verify belt tracking and tension according to the equipment manufacturer guidelines before resuming operation. When using liquid lubricants, ensure the work area and drainage are set up to handle coolant runoff safely.
