Built for precision deburring, sanding, and controlled finishing in confined work areas, the Dotco 12LF280-32OH Precision Right Angle Die Grinder combines a 0.4 HP pneumatic motor with a 12,000 RPM free speed for smooth material removal using properly rated accessories. Its 1/4″-28 internal thread collet supports compatible threaded accessories, while the compact right-angle head improves access around fixtures, inside assemblies, and along recessed surfaces. The rear exhaust directs discharged air away from the work area and supports overhose exhaust setups where airflow control is needed.Part of the 12LF Series, this compact Dotco tool is suited for detailed production work where control, reach, and repeatability matter. The lower 12,000 RPM speed helps improve handling during precision finishing, edge cleanup, mold work, aerospace component finishing, and industrial MRO applications where a straight grinder is difficult to position.Type: Precision Right Angle Die Grinder | Series: 12LF Series | Power: 0.4 HP | Free Speed: 12,000 RPM | Collet: 1/4″-28 internal thread | Housing: Composite | Exhaust: Rear | Air Inlet: 1/4″ | Minimum Hose I.D.: 1/4″ | Rated Pressure: 90 PSIFeatures:0.4 HP pneumatic motor supports controlled grinding, sanding, and finishing operations.12,000 RPM free speed provides improved control for detail work and precision material removal.Compact right-angle head reaches corners, recessed areas, and restricted workspaces.1/4″-28 internal thread collet accepts compatible threaded accessories.Composite housing helps reduce tool weight during repetitive production tasks.Rear exhaust directs discharged air away from the work surface and supports overhose installations.Balanced 12LF Series design supports steady handling during intricate finishing work.Supplied with angle-head grease and grease gun for routine maintenance.Made in USA: Applications:Precision deburring of machined parts and production components.Detail sanding and edge blending in fabrication and finishing departments.Die, mold, and fixture maintenance where right-angle access is required.Aerospace and composite finishing in restricted assembly areas.Industrial maintenance and repair work using compatible 1/4″-28 threaded accessories.FAQs:Q: What does 1/4″-28 internal thread mean?A: It refers to a threaded accessory connection. Use only compatible 1/4″-28 threaded accessories that match the tool and are rated for at least 12,000 RPM.Q: Is this the same as a standard 1/4″ collet grinder?A: No. This model uses a 1/4″-28 internal thread connection rather than a standard 1/4″ shank collet, so accessory compatibility must be verified before ordering.Q: Why choose the 12,000 RPM version?A: The 12,000 RPM speed provides better control for precision finishing, edge blending, and detail work where slower accessory speed is preferred.Q: What is the benefit of rear exhaust?A: Rear exhaust routes discharged air away from the work surface and can support overhose exhaust setups for cleaner airflow management. .spec-accordion{width:100%;max-width:1200px;margin:1em
