Dotco 12L1080-36OH Inline Die Grinder | 12-10 Series | 0.3 HP | 30000 RPM | 1/4" Collet | Rear Exhaust

When small-area grinding, deburring, and die/mold cleanup call for a straight, controlled air tool, the Dotco 12L1080-36OH Inline Die Grinder delivers compact material removal power in the 12-10 Series. Its 0.3 HP (0.22 kW) motor and 30,000 RPM free speed support fast burr work, edge cleanup, and mounted wheel finishing where larger grinders are too bulky. The 1/4" 300 Series collet accepts common rotary accessories, while the inline body helps the operator guide the tool along casting edges, machined surfaces, and tight detail areas.

The rear exhaust OH configuration includes a 4 ft Overhose, an exhaust hose used to help suppress noise and route spent air away from the work area. With a 0.88 lb tool weight and 6" length, this Dotco die grinder is sized for controlled bench work, fabrication touch-up, tool room finishing, and maintenance deburring. It is rated for use at 90 PSI (620 kPa) and supports abrasive capacity up to a 1/2" carbide burr or 1" mounted wheel when the accessory speed rating is correct.
