Dotco 12L2080-01 Inline Grinder | 12-20 Series | 0.6 HP | 25,000 RPM | 1/4" Collet | Composite Housing | Rear Exhaust

Built for fast deburring, burr work, and compact finishing tasks, the Dotco 12L2080-01 Inline Grinder combines a 0.6 HP pneumatic motor with a high 25,000 RPM free speed for controlled material removal using properly rated carbide burrs and mounted wheels. The 1/4" collet accepts common die grinder accessories, while the rear exhaust configuration routes exhaust air away from the work area to help reduce chip disturbance on precision cleanup jobs.

Part of the Dotco 12-20 Series, this inline grinder uses a lightweight composite housing and compact 6.9" body to help operators guide the tool through close-access grinding, edge blending, casting cleanup, and weld finishing. At 1.4 lbs., the 12L2080-01 gives fabrication shops, maintenance teams, and finishing departments a small straight grinder with the speed needed for fine control in corners, pockets, and tight assemblies.

Applications:

• Metal fabrication and welding shops — removing burrs, blending weld starts and stops, and cleaning small edges before finishing or assembly.
• Industrial maintenance and MRO — touching up brackets, guards, replacement parts, and machinery components during repair work.
• Automotive, fleet, and performance work — port cleanup, gasket surface preparation, small casting correction, and general garage grinding with compatible accessories.
• Tool, die, and mold work — refining pockets, contours, and machined features where a straight inline grinder offers better hand control.
• Aerospace and composite departments — controlled trimming, deburring, and detail finishing on small features when the accessory is matched to the material and tool speed.

FAQs:

• Q: What accessories can be used with the Dotco 12L2080-01?
  A: This grinder uses a 1/4" collet and is listed for 3/4" carbide burrs and 1-1/2" mounted wheels. The accessory’s shank size, diameter, and maximum operating speed must match the tool before use.
• Q: Why choose the 25,000 RPM version instead of a slower inline grinder?
  A: The 25,000 RPM speed is useful for fast deburring and fine finishing with smaller compatible accessories. Slower models may be preferred when the accessory manufacturer requires a lower speed or when more control is needed on delicate materials.
• Q: What is the benefit of rear exhaust on this model?
  A: Rear exhaust vents air behind the tool instead of toward the workpiece. This can be helpful when forward airflow would scatter chips, abrasive dust, or layout marks near the grinding area.
• Q: What air supply does this grinder require?
  A: Cleco rates the 12-20 Series at 90 PSI / 620 kPa and lists a 1/4" minimum hose I.D. Use clean, regulated, lubricated air and avoid undersized fittings that restrict air volume.
• Q: Can this tool be used with saw blades or cut-off wheels?
  A: No. This inline grinder is intended for compatible die grinder accessories such as properly rated carbide burrs and mounted wheels. Saw blades and non-reinforced grinding wheels should never be mounted on this tool.
