3M 7000000444 Flap Wheel 747D 2 Inch 80 Grit Ceramic

Product Description

The 3M 7000000444 Flap Wheel 747D is a coated abrasive wheel engineered for light grinding, blending, deburring, and polishing on metal surfaces. Built around a ceramic aluminum oxide abrasive blend, it delivers a strong cut rate with extended service life compared to standard aluminum oxide wheels. The abrasive flaps are mounted on an X-weight cotton cloth backing bonded with a resin system that resists thermal and chemical breakdown. At 2 inches in diameter and 80 grit, this wheel suits finishing work where surface conformity and a smooth, clean finish are the primary goals. Trades working with stainless steel, carbon steel, and non-ferrous metals will find this wheel a practical choice for production and maintenance applications.

The 747D Flap Wheel is suited for use on rounded, contoured, and irregular metal surfaces where rigid abrasive tooling cannot conform properly. It is commonly used in metal fabrication shops, HVAC sheet-metal work, plumbing rough-in, and general industrial maintenance. The flexible flap design allows the abrasive to follow the contour of the workpiece, reducing the risk of gouging and producing a uniform finish across the surface. A built-in grind-aid additive helps the wheel run cooler, which is especially useful when working on stainless steel or other heat-sensitive metals.

Key Features

• Ceramic aluminum oxide blend provides high cut rate and long abrasive life
• X-weight cotton cloth backing handles aggressive grinding without tearing
• Resin bond resists heat and chemical exposure for extended wheel life
• Flexible flap design conforms to rounded and irregular surfaces for a smooth finish
• Integrated grind-aid additive reduces heat buildup on stainless steel and other metals
• 80 grit coated construction suited for blending, deburring, and light stock removal

Compatibility

Designed as an OEM-style abrasive replacement wheel for use on standard rotary die grinders and finishing tools that accept 2-inch flap wheel arbors in metal fabrication and maintenance applications.

Installation Notes

Installation should be performed by a qualified technician familiar with rotary abrasive tooling. Verify that the tool spindle speed does not exceed the maximum rated RPM marked on the wheel or its packaging before mounting. Power down and de-energize the tool completely before changing wheels. Inspect the wheel for cracks or damage prior to each use and do not use a damaged wheel.
