3M 7000047055 Unitized Abrasive Wheel 4 Inch Silicon Carbide

Product Description

The 3M 7000047055 is a unitized, non-woven abrasive wheel from the Standard Abrasives 700 Series, designed for fine finishing work on hard and exotic metals. It features a medium to hard density construction with silicon carbide mineral, which delivers consistent cut and finish even on demanding materials such as titanium, stainless steel, and other ferrous and non-ferrous alloys. The open web design resists loading, extending the usable life of the wheel. It attaches to a standard tool arbor using a unitized wheel mandrel, sold separately. Weighing 2.322 pounds and measuring 4 inches in diameter, this wheel is suited for bench or portable grinding and finishing setups.

This wheel is intended for metal finishing applications where a controlled, fine surface profile is required. It is commonly used in fabrication shops, aerospace maintenance, and general metalworking environments. Suitable applications include edge blending, light deburring, and surface conditioning on hard metals including titanium and composites. The silicon carbide abrasive makes it compatible with both ferrous and non-ferrous base materials. The wheel runs clockwise and counterclockwise, offering flexibility in tool orientation and setup.

Key Features

• Medium to hard density construction for aggressive, long-lasting performance on hard metals
• Silicon carbide mineral rated for ferrous metals, non-ferrous metals, exotic alloys, titanium, and composites
• Open web structure resists loading and extends abrasive service life
• Runs clockwise and counterclockwise for versatile tool compatibility
• Increased edge durability compared to 600 Series Unitized Wheels
• Center hole design mounts with a unitized wheel mandrel (sold separately)

Compatibility

Designed for use with standard right-angle grinders and bench-mounted tools that accept a unitized wheel mandrel. Compatible with ferrous metals, non-ferrous metals, exotic metals including titanium, and composite materials.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety. Ensure the tool is powered off and unplugged before mounting or removing the wheel. Verify that the tool RPM rating meets or exceeds the wheel RPM rating before operation. A compatible unitized wheel mandrel is required and is not included with this wheel.
