3M 7100142488 Quick Change Unitized Wheel 3 Inch

Product Description

The 3M 7100142488 is a quick change unitized abrasive wheel from the Standard Abrasives 700 Series, designed for fine finishing work on smaller surface areas and tight geometries. Built with medium to hard density construction and silicon carbide mineral, it delivers consistent stock removal and smooth surface finish on hard metals including titanium, stainless steel, and other ferrous and non-ferrous alloys. At 3 inches in diameter, the wheel mounts to standard quick change tool holders for fast disc swaps without interrupting workflow. Metal fabricators, aerospace technicians, and industrial finishers working with exotic metals and composites are the primary users of this wheel.

This wheel is suited for finishing and blending applications on smaller workpiece sections where control and edge durability matter. The 700 Series construction offers increased hardness and edge life compared to 600 Series unitized wheels, making it appropriate for more aggressive finishing passes on hard substrate materials including titanium and composites. Typical use cases include weld blending, surface conditioning, and edge finishing in fabrication shops, aerospace maintenance, and precision metalworking environments.

Key Features

• Medium to hard density silicon carbide construction for tough finishing on hard metals and exotic alloys including titanium
• Increased edge durability over 600 Series unitized wheels for longer service life and more aggressive material removal
• Silicon carbide mineral works on ferrous metals, non-ferrous metals, exotic alloys, and composites
• Open web construction resists loading for extended abrasive service life
• Quick change mount allows fast disc swaps to maintain tool efficiency and reduce downtime

Compatibility

Designed for use with standard quick change tool holders compatible with 3-inch unitized wheels. Replaces or supplements 600 Series unitized wheels where harder density and greater edge durability are required.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using compatible quick change angle grinders or die grinders. Confirm the tool spindle speed rating meets or exceeds the wheel maximum RPM before mounting. Power down and disconnect the tool from its power source before changing wheels. Inspect the wheel for visible damage before each use and do not use a damaged or deformed wheel.
