3M 7100138162 Flap Wheel 747D 3 Inch Ceramic 80 Grit

Product Description

The 3M 7100138162 is the 747D flap wheel, a ceramic abrasive grinding and finishing wheel built for light grinding, blending, deburring, and polishing on metals. The wheel features flexible abrasive flaps mounted on a central hub, allowing them to conform to curved, rounded, or irregular workpiece surfaces during operation. The ceramic aluminum oxide abrasive blend delivers a high cut rate alongside extended service life. An X-weight cotton cloth backing supports aggressive stock removal without premature breakdown. A grind-aid additive is integrated into the abrasive to reduce heat buildup when working stainless steel and other metals.

This flap wheel is suited for metal fabrication shops, maintenance and repair operations, and production environments where consistent surface finishing results are required. Typical applications include weld blending, edge deburring, and surface conditioning on ferrous and non-ferrous metals. The 3-inch diameter and 80-grit rating make it appropriate for moderate material removal combined with a smooth finish pass. It is commonly used by fabricators, machinists, and metal finishing tradespeople working with angle grinders or similar rotary equipment.

Key Features

• Ceramic aluminum oxide abrasive blend for high cut rate and extended wheel life
• Abrasive flaps conform to rounded and irregular surfaces for consistent contact
• X-weight cotton cloth backing withstands aggressive sanding and grinding loads
• Resin bond resists thermal and chemical deterioration during extended use
• Integrated grind-aid provides cooler running on stainless steel and other metals
• 80 grit rating balances material removal with a smooth, clean surface finish

Compatibility

Designed for use on a variety of ferrous and non-ferrous metals including stainless steel; compatible with rotary tools and angle grinders accepting 3-inch flap wheel arbors.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with rotary abrasive tooling. Verify that the tool spindle speed does not exceed the maximum rated RPM of the wheel before mounting. Ensure the workpiece is secured and appropriate personal protective equipment including eye and face protection is worn during operation. Inspect the wheel for damage before each use and discard if any cracks, tears, or delamination are present.
