3M 7000121949 Unitized Abrasive Wheel Ao Non-woven 2 in

Product Description

The 3M 7000121949 is an extra-hard density unitized abrasive wheel designed for aggressive deburring and finishing on ferrous and non-ferrous metals. Built on a non-woven aluminum oxide construction, this 900 Series wheel delivers the highest level of mineral density and edge durability within the Standard Abrasives Unitized Wheels line. At 2 inches in diameter, it mounts to standard unitized wheel mandrels and is suited for use on grinders, die grinders, and bench-mounted tools. Metal fabricators and finishing technicians turn to this wheel for heavy-duty burr removal and surface conditioning on harder metals where lesser wheels wear quickly.

This wheel is well suited for industrial and shop environments where consistent edge deburring and surface finishing are required on both ferrous and non-ferrous materials, including aluminum. Its extra-hard density construction makes it a practical choice for high-cycle production finishing operations and maintenance shops handling tough stock removal tasks. The wheel runs in both clockwise and counterclockwise directions, giving technicians flexibility when pairing it with various tool configurations. It attaches via a unitized wheel mandrel sold separately.

Key Features

• Extra-hard density non-woven construction delivers aggressive edge deburring and coarse-to-medium finishing
• Aluminum oxide mineral is compatible with ferrous and non-ferrous metals, including aluminum
• Increased edge durability compared to 800 Series Unitized Wheels, extending wheel life on heavy-duty tasks
• Bidirectional operation — runs clockwise and counterclockwise for tool versatility
• Center-hole design mounts to unitized wheel mandrels (mandrel sold separately)

Compatibility

Designed as an OEM-style replacement or standard consumable for use with unitized wheel mandrels on die grinders, right-angle grinders, and bench-mounted finishing tools accepting 2-inch diameter center-hole unitized wheels.

Installation Notes

Installation is performed by metalworking technicians or finishing shop personnel. Power down and disconnect the tool from its power source before mounting or removing the wheel. Ensure the mandrel is rated for the wheel diameter and RPM range of the tool before operation. Follow all applicable ANSI safety standards for abrasive wheel mounting and operation, and verify the tool guard is in place prior to use.
