Built for precision material removal in hard-to-reach areas, the Dotco 10L1181-36 Inline Extended Grinder combines a compact inline configuration with an extended reach to access recessed surfaces, deep cavities, narrow channels, and intricate components that standard die grinders cannot easily reach. Powered by a 0.3 HP pneumatic motor and operating at a 28,000 RPM free speed, this grinder provides the high rotational speed needed for efficient deburring, blending, polishing, and finishing while maintaining excellent control during detailed work. Its 1/4" collet accepts a wide range of carbide burrs, mounted points, and rotary accessories, making it a versatile choice for production environments and precision maintenance tasks.
The grinder features a lightweight aluminium housing that reduces operator fatigue during extended operation, while the rear exhaust directs spent air away from the workpiece to improve visibility and keep debris away from finished surfaces. As part of Dotco's proven 10-11 Series, this extended inline grinder is well suited for aerospace manufacturing, metal fabrication, industrial maintenance, foundries, and other applications where accuracy, accessibility, and consistent pneumatic performance are essential.
