Built for fast burr work, edge blending, and detailed material removal with metric-shank accessories, the Dotco 12L2580-01M6OH Inline Die Grinder pairs 0.9 HP output with a high-speed 23,000 RPM motor for quick stock removal in compact grinding applications. Its 6mm collet (the clamping sleeve that holds compatible metric rotary burrs and mounted abrasives) supports shops that use metric tooling for fabrication, repair, toolroom, and production maintenance work.
Part of the 12-25 Series, this Dotco inline die grinder uses a composite housing to help reduce hand fatigue during repeated deburring and finishing tasks. The rear exhaust with OH overhose routes exhaust air away from the work area and operator, helping reduce chip blowback and noise exposure compared with a direct front-exhaust layout. With capacity for a 1" carbide burr and 1.5" mounted wheel, the 12L2580-01M6OH is a strong fit for technicians who need speed, control, and clean exhaust routing in one compact pneumatic grinder.

Applications:
- Metal fabrication and welding — removing burrs, blending weld starts and stops, cleaning brackets, and preparing small areas before finishing.
- Toolroom and die maintenance — shaping small features, cleaning cavities, breaking sharp edges, and refining machined details with compatible 6mm accessories.
- Industrial maintenance and MRO — deburring replacement parts, cleaning repair surfaces, and handling general pneumatic grinding tasks around plant equipment.
- Transportation and equipment repair — cleaning castings, brackets, frames, and service parts where a compact straight grinder provides better access.
- Production finishing — repetitive edge cleanup, part blending, and small-area material removal where rear exhaust helps keep air away from the work zone.
FAQs:
- Q: What accessories fit the Dotco 12L2580-01M6OH?
A: This model uses a 6mm collet and is intended for compatible 6mm shank carbide burrs and mounted abrasive accessories. The listed capacity is up to a 1" carbide burr or 1.5" mounted wheel. - Q: What does the OH suffix mean?
A: The OH suffix identifies an overhose configuration. On this rear-exhaust grinder, the overhose helps route exhaust air away from the operator and work area. - Q: Why choose this 23,000 RPM model instead of a 12,000 RPM grinder?
A: The 23,000 RPM version is better suited for faster burr work, lighter stock removal, and finishing tasks where higher accessory speed is useful. The 12,000 RPM version may be preferred for larger accessories, more control, or applications where lower speed reduces heat or chatter. - Q: Can this grinder be used with 1/4" shank accessories?
A: This SKU is specified with a 6mm collet, so it should be used with compatible 6mm shank accessories unless the correct manufacturer-approved collet is installed. Do not force undersized or oversized accessory shanks into the collet. - Q: What air supply does this Dotco grinder require?
A: The tool is rated at 90 PSI / 620 kPa and requires a minimum 5/16" hose I.D. Use clean, regulated, lubricated air to help maintain grinder speed and protect internal components.
