3M 7100142326 T27 Angle Grinder 1 Hp 4.5 Inches

Product Description

The 3M 7100142326 is a T27 right-angle grinder designed for demanding grinding and surface conditioning work in industrial and trade environments. Rated at 1 hp, it accepts 4.5-inch bonded, coated, and surface conditioning discs mounted on a 5/8-11 external thread spindle. The steel gear head features a right-angle design with a grease fitting to extend gear service life. A rear exhaust port directs air away from the work surface. The tool weighs 5.51 pounds, making it manageable for extended overhead or side-angle work. A 3/8-inch to 1/4-inch air inlet reducer is included, allowing connection to a range of compressed-air supply lines.

This grinder is suited for metal fabrication, weld blending, deburring, and surface preparation tasks in both shop and field settings. The included removable side handle supports two-handed control during prolonged use. The repositionable guard can be adjusted to improve surface visibility depending on the work angle. 3M Gripping Material is molded directly into the housing, reducing operator fatigue during extended operation. Licensed trade professionals and experienced fabricators will find this tool compatible with standard 4.5-inch disc accessories used in structural steel, manufacturing, and mechanical service work.
