Dotco 12L2680-01 Extended Inline Grinder | 12-26 Series | 0.9 HP | 22,000 RPM | 1/4" Collet | Composite Housing | Rear Exhaust

Built for precision deburring, weld blending, porting, and finishing in areas that standard grinders cannot easily reach, the Dotco 12L2680-01 Extended Inline Grinder combines a 0.9 HP pneumatic motor with a 5 in. extended housing and a 22,000 RPM free speed to deliver controlled material removal in confined spaces. The extended nose provides improved access inside castings, fabricated assemblies, molds, and machined components while maintaining the balance and control expected from the Dotco 12-26 Series.

Featuring a 1/4" 200 Series collet, rear exhaust, and a composite housing, this grinder is well suited for carbide burrs and mounted points used in production manufacturing, aerospace, metal fabrication, and industrial maintenance. The rear exhaust helps direct airflow away from the work area, while the lightweight composite body supports comfortable handling during extended operation.
