3M 7100020239 Abrasive Belt 75x37 in 36 Grit Ceramic Ao

Product Description

The 3M 7100020239 is a coated abrasive belt engineered for high-demand stock removal and metal finishing applications. It combines 3M ceramic abrasive grain with aluminum oxide in a blend that cuts faster and lasts longer than standard aluminum oxide belts. The heavyweight polyester cloth backing handles high-pressure grinding and runs equally well dry or with a lubricant. A built-in grinding aid reduces heat buildup at the contact point, making this belt well suited for stainless steel and other heat-sensitive metals. Licensed metalworking and fabrication shops rely on this belt for consistent cut rate and extended service life between belt changes.

This belt is built for industrial and commercial metalworking environments where throughput and belt longevity are priorities. It performs in stock removal, weld blending, and surface finishing on ferrous and non-ferrous metals. The 75-inch length and 37-inch width fit wide-belt and stroke-sander configurations common in fabrication shops. The 36-grit designation targets aggressive material removal rather than finish work. The orange color aids in quick visual identification on the shop floor.

Key Features

• Ceramic and aluminum oxide grain blend delivers faster cut rate and longer life than traditional AO belts
• Heavyweight polyester cloth backing supports high-pressure applications without breakdown
• Runs wet or dry, giving operators flexibility with or without lubricant
• Grinding aid reduces heat generation, extending performance life on stainless steel and heat-sensitive metals
• Durable resin bond resists heat deterioration to maximize belt longevity
• 36-grit abrasive targets aggressive stock removal in weld blending and heavy finishing

Compatibility

Designed for wide-belt and stroke-sander machines accepting a 75-inch by 37-inch abrasive belt in industrial metalworking and fabrication applications.

Installation Notes

Belt installation and tensioning should be performed by a qualified operator following the machine manufacturer's guidelines. Power down and lock out the sander before changing belts. Confirm proper belt tracking and tension before resuming operation. Inspect the belt for tears or edge damage prior to each use, and never exceed the machine's rated operating speed.
