3M 7000119447 Abrasive Belt 75x36 Inch 120 Grit Alumina Zirconia

Product Description

The 3M 7000119447 is an alumina zirconia coated abrasive belt designed for high-production grinding, blending, and finishing operations. The 577F construction pairs a tough alumina zirconia mineral with a built-in grinding aid, delivering faster cut rates and longer service life compared to standard aluminum oxide belts. The heavyweight, water-resistant polyester cloth backing supports high-pressure contact and aggressive edge work without delaminating or stretching. At 75 inches long and 36 inches wide, with a 120 grit rating, this belt suits wide-format grinding applications in metal fabrication, welding shops, and industrial finishing environments. The alumina zirconia grain runs cooler than aluminum oxide, making it suitable for heat-sensitive metals such as aluminum and stainless steel.

This belt is used in wide-belt sanders and abrasive platen grinders found in metal fabrication shops, aerospace component finishing, and structural steel operations. The 120 grit classification positions it for intermediate stock removal and surface conditioning work, bridging the gap between aggressive material removal and finish preparation. Its cool-running mineral is especially useful when workpiece temperature control is critical, such as on stainless steel components where heat-induced discoloration or distortion must be avoided. Metal finishing professionals and industrial maintenance crews are the primary installers and operators of this belt type.

Key Features

• Alumina zirconia mineral with grinding aid cuts faster and lasts longer than aluminum oxide
• Runs cool, reducing heat buildup on heat-sensitive metals including aluminum and stainless steel
• Heavyweight water-resistant polyester cloth backing handles high-pressure applications and edge work
• 120 grit provides effective intermediate stock removal and surface conditioning
• Large 75 inch by 36 inch format suits wide-belt industrial grinding equipment

Compatibility

Designed for use on wide-belt abrasive machines that accept 75 inch by 36 inch belts; suitable for grinding and finishing operations on metal substrates including steel, aluminum, and stainless steel.

Installation Notes

Belt installation and tension adjustment should be performed by qualified personnel following the machine manufacturer's guidelines. Power down and lock out the machine before mounting or removing the belt. Inspect the belt for tears, edge damage, or delamination before each use. Ensure belt tracking is set correctly before resuming production to prevent edge wear and potential belt failure.
