3M 7100032738 Ceramic Flap Wheel 60 Grit 3 Inch

Product Description

The 3M 7100032738 is a ceramic flap wheel designed for light grinding, blending, deburring, and polishing on metal surfaces. Part of the 747D series, it uses a ceramic aluminum oxide abrasive blend bonded to X-weight cotton cloth flaps. The flap construction allows the wheel to conform to rounded and irregular workpiece profiles, delivering a smooth, consistent finish. Resin bonding holds the abrasive securely, resisting heat and chemical breakdown during extended use. A built-in grind-aid compound promotes cooler operation, particularly on stainless steel. This wheel is suited for use by fabricators, welders, and metal finishing tradespeople working on a range of ferrous and non-ferrous metals.

The 7100032738 is intended for light material removal, surface blending, and finishing applications in fabrication shops, maintenance environments, and field service work. It performs well on contoured or irregular surfaces where rigid abrasive tooling cannot maintain consistent contact. The 3-inch diameter and 60-grit ceramic abrasive make it appropriate for medium-cut finishing passes on stainless steel, carbon steel, and similar metals. It is typically mounted on a mandrel and driven by a die grinder or similar rotary tool.

Key Features

• Ceramic aluminum oxide abrasive blend provides high cut rate and extended wheel life
• X-weight cotton backing withstands aggressive grinding and sanding conditions
• Resin bond resists thermal and chemical deterioration for consistent performance over time
• Flap design conforms to curved and irregular surfaces for uniform stock removal
• Integrated grind-aid promotes cooler cutting on stainless steel and other metals
• 60-grit ceramic construction suits light grinding and blending operations

Compatibility

Designed for use on a variety of metals including stainless steel, carbon steel, and similar ferrous and non-ferrous materials. Intended for use with mandrel-mounted rotary tools such as die grinders rated for the wheel diameter and speed.

Installation Notes

Mount the flap wheel on a compatible mandrel rated for the wheel diameter before attaching to the rotary tool. Verify that the tool RPM rating does not exceed the maximum rated speed of the wheel before operation. Always wear appropriate eye protection and gloves when operating abrasive wheels. Inspect the wheel for damage before each use and do not use a wheel that shows signs of wear-through, delamination, or physical damage.
