Dotco 12L2080-01M6 Inline Die Grinder | 12-20 Series | 0.6 HP | 25000 RPM | 6mm Collet | Rear Exhaust

Built for fast deburring, edge blending, and controlled material removal with metric-shank accessories, the Dotco 12L2080-01M6 Inline Die Grinder delivers 0.6 HP output and a high 25,000 RPM free speed for smooth cutting action with properly rated carbide burrs and mounted wheels. It's 6mm collet supports common metric tooling, while the inline body gives technicians a straight working approach for cleaning ports, finishing slots, removing casting flash, and dressing small fabricated parts.

Part of the Dotco 12-20 Series, this model uses rear exhaust to route spent air away from the work surface, helping reduce chip movement around the grinding point. The composite housing keeps the tool compact and manageable at 1.4 lbs, making it a practical choice for production deburring, repair work, and detailed finishing where a full-size wheel grinder would remove too much material.

FAQs:

• Q: What is the difference between a 6mm collet and a 1/4" collet?
  A: A 6mm collet is sized for metric-shank accessories, while a 1/4" collet is for inch-size shanks. They are close in size but not interchangeable for safe, secure accessory holding.
• Q: What accessories can be used with the Dotco 12L2080-01M6?
  A: This grinder is rated for a 3/4" carbide burr or a 1-1/2" mounted wheel. Accessories must fit the 6mm collet and have a maximum operating speed equal to or greater than 25,000 RPM.
• Q: Why choose rear exhaust on an inline die grinder?
  A: Rear exhaust directs air away from the grinding point, which can help keep chips and debris from being blown across the work surface during detail work.
• Q: What air setup does this grinder require?
  A: The tool is performance rated at 90 PSI / 620 kPa and should be used with a minimum 1/4" hose I.D. A regulated, lubricated air supply helps maintain speed and protect the motor.
• Q: Is this grinder suitable for precision deburring?
  A: Yes, its inline shape, 6mm collet, and 25,000 RPM speed make it well suited for controlled deburring and small-area finishing when paired with the correct burr or mounted point.
