3M 7100189350 Abrasive Belt 60 Grit 42x1 Inch Cloth

Product Description

The 3M 7100189350 is a Cubitrona II cloth abrasive belt designed for medium-pressure grinding and blending on metal surfaces. It uses 3M Precision-Shaped Grain, a blend of shaped ceramic and premium aluminum oxide minerals, to deliver faster stock removal and longer service life compared to conventional ceramic aluminum oxide belts. The belt measures 42 inches in length and 1 inch in width, runs at 60 grit, and features a YF-weight polyester backing with a waterproof construction and integrated grinding aid. It is suited for both wet and dry applications and is a common choice for fabrication shops running robotic or pressure-assisted grinding equipment.

This belt is built for grinding and blending on all metals, including heat-sensitive alloys where the grinding aid helps control surface temperatures. The moderately flexible backing conforms to both straight and contoured workpiece profiles, making it useful across a range of part geometries. Typical applications include weld blending, deburring, surface finishing, and stock removal on structural steel, stainless steel, aluminum, and other metal substrates. The durable resin bond resists heat-related deterioration, extending usable belt life and reducing changeout frequency in high-volume production environments.

Key Features

• 3M Precision-Shaped Grain blend of shaped ceramic and premium aluminum oxide for faster, more consistent cut
• Significantly longer belt life compared to conventional aluminum oxide belts
• Waterproof YF-weight polyester backing with moderate flexibility for straight and contoured surfaces
• Integrated grinding aid cools the abrasive process on heat-sensitive alloys
• Suitable for wet and dry use on all metals
• Durable resin bond resists heat deterioration and extends belt service life
• Reduces changeout frequency in robotic and pressure-assisted grinding setups

Compatibility

Designed for use on standard 1-inch-wide belt grinders and finishing machines configured for 42-inch belt length, in medium-pressure grinding and blending applications on metal substrates.

Installation Notes

Belt installation and replacement should be performed by qualified personnel following the machine manufacturer's instructions. Power down and lock out the grinder before mounting or removing a belt. Verify belt tracking and tension per machine specifications before resuming operation. Inspect the belt for tears or joint separation prior to each use.
