Dotco 12L2580-36 Inline Grinder | 12-25 Series | 0.9 HP | 23,000 RPM | 1/4" Collet | Composite Housing | Rear Exhaust

Built for deburring, die work, weld cleanup, and fine material removal, the Dotco 12L2580-36 Inline Grinder delivers 0.9 HP in a compact straight-body tool that gives technicians strong cutting power without stepping up to a larger wheel grinder. It's 23,000 RPM free speed supports fast burr work and mounted point finishing, while the 1/4" collet (the clamping sleeve that holds compatible rotary burrs and mounted abrasives) fits common shop accessories used in fabrication, transportation, and industrial maintenance.

The 12-25 Series composite housing helps keep tool weight under 2 pounds for better hand control during detailed grinding, blending, and edge-break work. A rear exhaust configuration routes spent air away from the work area, which helps reduce chip and dust disturbance when working near fixtures, cavities, or finished surfaces. With capacity for a 1" carbide burr and 1-1/2" mounted wheel, this Dotco grinder is a practical choice for metal removal tasks that require both reach and precision.

Applications:

• Metal fabrication and welding — cleaning weld edges, blending small beads, removing burrs, and preparing tight areas before finishing.
• Tool and die work — shaping, porting, slot cleanup, and detail grinding where a straight inline body gives good directional control.
• Transportation and fleet maintenance — deburring brackets, grinding small castings, and cleaning repair areas on trucks, trailers, and equipment.
• Industrial MRO — removing sharp edges, cleaning machined parts, and performing general shop grinding with compatible carbide burrs or mounted wheels.
• DIY garage and restoration work — controlled metal cleanup on brackets, frames, engine parts, and repair panels when paired with a properly sized compressor.

FAQs:

• Q: What accessories fit the Dotco 12L2580-36?
  A: This model uses a 1/4" collet and accepts compatible 1/4" shank carbide burrs and mounted abrasive points. The manufacturer lists capacity up to a 1" carbide burr and 1-1/2" mounted wheel.
• Q: What does rear exhaust mean on an inline grinder?
  A: Rear exhaust routes spent air toward the back of the tool instead of toward the workpiece. This is useful when grinding in tight spaces or near finished surfaces because it helps reduce debris blowback at the point of work.
• Q: Is this grinder suitable for precision deburring?
  A: Yes, the inline body, light weight, 23,000 RPM speed, and 1/4" collet make it well suited for deburring, edge breaking, and controlled burr work. Accessory selection should match the material, finish requirement, and tool speed.
• Q: What air setup should be used with this grinder?
  A: The tool is performance rated at 90 PSI / 620 kPa and requires a minimum 5/16" hose I.D. Use clean, regulated, lubricated air and avoid undersized hose or fittings that can restrict airflow.
• Q: Does this model include an overhose?
  A: No, OH models include a 4' overhose. This rear exhaust model can be fitted with an available conversion kit if additional noise suppression is needed.
