Dotco 12L2082-01 Inline Grinder | 12-20 Series | 0.6 HP | 18,000 RPM | 1/4" Collet | Composite Housing | Rear Exhaust

For shops that need a controlled inline grinder with slightly lower accessory speed than the 20,000 and 25,000 RPM models in the same family, the Dotco 12L2082-01 delivers 18,000 RPM free speed in a compact 12-20 Series configuration. Its 0.6 HP air motor provides practical cutting power for deburring, blending, edge cleanup, and small-area material removal, while the 1/4" collet accepts common shank-mounted carbide burrs and mounted wheels used in die grinding work.

The composite housing keeps the tool light at 1.4 lb, which helps during repeated bench, fixture, and handheld finishing tasks. Its rear exhaust design routes spent air toward the back of the tool, helping keep exhaust flow away from the grinding point and work surface. A lock-off lever throttle (a safety-style lever that helps reduce accidental starts) makes the 12L2082-01 a good fit for production deburring stations, tool rooms, fabrication shops, and maintenance departments that rely on consistent 1/4" collet grinding tools.

Applications:

• Machining and CNC support — removing burrs from milled, drilled, and turned parts before inspection or assembly.
• Die and mold work — refining details, cleaning edges, and shaping small areas with compatible carbide burrs.
• Metal fabrication — smoothing cut edges, cleaning holes, and blending localized areas on brackets, frames, and fixtures.
• Industrial maintenance and MRO — preparing replacement parts, modifying small components, and handling routine shop deburring.
• Automotive and garage repair — cleaning gasket surfaces, dressing brackets, and performing general air-tool grinding when accessory speed ratings match the tool.

FAQs:

• Q: What is the difference between the 12L2082-01 and faster 12-20 Series models?
  A: The 12L2082-01 runs at 18,000 RPM, while nearby models in the same family include 20,000 and 25,000 RPM versions. The lower speed may be preferred when the accessory, material, or finish requirement calls for a more controlled cutting rate.
• Q: What accessories can I use with this grinder?
  A: This model uses a 1/4" collet and is listed for a 3/4" carbide burr and a 1.5" mounted wheel. Always confirm that the accessory’s maximum safe operating speed is equal to or greater than 18,000 RPM before use.
• Q: Why choose rear exhaust on an inline die grinder?
  A: Rear exhaust directs spent air toward the back of the tool rather than near the accessory. This can help keep exhaust flow from disturbing chips, dust, or fine debris at the grinding point.
• Q: Does the Dotco 12L2082-01 include a collet?
  A: Yes. The catalog lists standard equipment as the applicable collet and collet wrenches.
• Q: What air setup is needed for this tool?
  A: The tool is rated at 90 PSI / 620 kPa and requires a minimum 1/4" hose I.D. The available source data does not list air consumption, so confirm compressor capacity before assigning the tool to continuous-duty production work.
