3M 7100142323 Die Grinder 1 Hp 12000 Rpm 1/4 Inch Collet

Product Description

The 3M 7100142323 is a straight-shaft pneumatic die grinder built for material removal, deburring, grinding, and surface preparation in demanding trade and industrial environments. Running at 12,000 RPM with a 1 HP output, it delivers consistent power for extended use on metal, welds, and composite surfaces. The 1/4-inch collet accepts a wide range of mounted points, carbide burrs, and abrasive accessories. At 2.77 pounds, the tool is light enough to reduce operator fatigue during repetitive overhead or confined-space work. Licensed tradespeople and industrial technicians are the primary installers and operators of this tool.

This die grinder is suited for metal fabrication shops, HVAC duct work, pipefitting, and general mechanical service where precision grinding or finishing in tight spaces is required. The straight-shaft design allows direct inline access to workpieces in areas where angle grinders cannot reach. It is appropriate for both bench work and in-place component finishing on installed systems.

Installation Notes

This tool is operated by qualified tradespeople familiar with pneumatic tool safety procedures. Verify that the air supply pressure and CFM rating of the compressor match the tool's requirements before connecting. Always inspect the collet and accessory shank for wear or damage before mounting a grinding bit, and ensure the accessory is rated for the tool's maximum RPM. Disconnect the air supply before changing accessories or performing any maintenance.
