3M 7100142494 Extended Die Grinder 1 Hp 18000 Rpm

Product Description

The 3M 7100142494 is a straight-shaft extended pneumatic die grinder built for heavy-duty material removal in confined and hard-to-reach areas. Its shaft is extended 3 inches beyond a standard die grinder profile, giving technicians additional reach without sacrificing control. The tool delivers 1 HP and spins at 18,000 RPM through a 1/4 inch collet, making it well suited for weld removal, stock removal, deburring, and surface preparation. 3M Gripping Material is integrated into the housing to help dampen vibration and maintain a secure hold during extended use. An adjustable directional exhaust allows the operator to redirect airflow away from the work area or the operator in any direction.

This grinder is designed for trade and industrial professionals who need consistent pneumatic cutting and grinding performance in tight spaces. Typical applications include fabrication shops, welding operations, automotive service, and maintenance environments where standard-length tools cannot reach the work surface. It is driven by compressed air, making it appropriate for shop environments with an existing air supply system.
