3M 7000144172 Unitized Abrasive Wheel 2 in Aluminum Oxide

Product Description

The 3M 7000144172 is a 2-inch diameter unitized abrasive wheel built for deburring, blending, and finishing operations on metal surfaces. Constructed with aluminum oxide mineral bonded into a non-woven fiber matrix, this extra-hard density wheel delivers aggressive material removal and durable edge performance. It is rated for the 900 Series Unitized Wheels line, positioning it as the densest and most aggressive option in that family. HVAC fabricators, sheet metal workers, pipefitters, and maintenance trades use this type of wheel for cleaning weld beads, removing burrs from cut edges, and surface conditioning prior to assembly or coating.

This wheel fits standard center-hole mandrel arbors and mounts to die grinders, bench grinders, or other rotary tools equipped with a compatible unitized wheel mandrel, sold separately. It is suited for use on ferrous and non-ferrous metals including mild steel, stainless steel, and aluminum. The wheel runs clockwise or counterclockwise, providing flexibility across a range of tool configurations and work orientations in shop or field settings.

Key Features

• Extra-hard non-woven aluminum oxide construction for aggressive edge deburring on hard metals
• Higher density and increased edge durability compared to 800 Series Unitized Wheels, extending service life on heavy-duty tasks
• Compatible with both ferrous and non-ferrous metals including aluminum
• Bi-directional operation — runs clockwise and counterclockwise for greater versatility
• Center-hole mounting design attaches to a unitized wheel mandrel (sold separately)

Compatibility

Designed for use with standard unitized wheel mandrels on die grinders and rotary tools accepting a center-hole abrasive wheel in a 2-inch diameter format.

Installation Notes

Installation is performed by qualified tradespeople familiar with abrasive wheel safety. Always power down and disconnect the tool before mounting or removing the wheel. Verify that the tool RPM rating meets or exceeds the wheel RPM rating before operation. Inspect the wheel for damage prior to each use and discard any wheel that shows cracking, fraying, or deformation. Follow ANSI B7.1 guidelines for the safe use, handling, and protection of abrasive wheels.
