3M 7000047040 Silicon Carbide Unitized Wheel 6 in

Product Description

The 3M 7000047040 is a 6-inch diameter silicon carbide unitized wheel from the Standard Abrasives 500 Series. It is engineered with a soft, conformable density for light-pressure blending, finishing, and polishing on flat or contoured surfaces. The open-web, non-woven construction resists loading, which extends abrasive service life and maintains cutting consistency. This wheel is sized for center-hole mounting and attaches to a compatible tool via a unitized wheel mandrel sold separately. Fabricators, metal finishers, and aerospace maintenance technicians are the primary users of this product.

This wheel is suited for work on ferrous metals, non-ferrous metals, exotic alloys including titanium, and composite materials. It performs well in applications where close tolerances demand a controlled, predictable cut. Typical use cases include surface blending after welding or grinding, pre-paint finishing, and light deburring on flat or contoured workpieces. The wheel runs in both clockwise and counterclockwise directions, which allows it to pair with a wide range of handheld and bench-mounted tools.

Key Features

• Soft density silicon carbide construction delivers a fine finish with controlled material removal
• Conformable non-woven web adapts to flat and contoured part geometries
• Cuts faster than buff-and-blend non-woven products while maintaining finesse for tight-tolerance work
• Compatible with ferrous metals, non-ferrous metals, exotic metals, titanium, and composites
• Bidirectional rotation for use with a broad range of power tools and machines
• Open-web structure resists loading and contributes to longer service life

Compatibility

Designed for use with a unitized wheel mandrel, sold separately. Center-hole design accommodates standard mandrel arbors used with angle grinders, die grinders, and bench-mounted finishing equipment. Specific mandrel compatibility should be confirmed prior to installation.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety. Disconnect and de-energize the tool before mounting or removing the wheel. Confirm that the tool RPM rating meets or exceeds the maximum rated speed of the wheel before operation. Always inspect the wheel for damage prior to each use and do not use damaged or deformed wheels.
