Dotco 12L2081-01M6OH Inline Die Grinder | 12-20 Series | 0.6 HP | 20000 RPM | 6mm Collet | Rear Exhaust

For controlled deburring, shaping, and finishing with mounted points or carbide burrs, the Dotco 12L2081-01M6OH Inline Die Grinder combines 0.6 HP output with a 20,000 RPM free speed for fast material removal without stepping up to a larger wheel grinder. The inline body gives the operator a straight approach to the workpiece, while the 6mm collet accepts compatible metric shank accessories used for edge cleanup, weld blending, mold work, and precision surface preparation.

Part of the Dotco 12-20 Series, this rear-exhaust model includes the OH overhose configuration, which routes exhaust air through a 4 ft overhose for additional noise suppression. Its composite housing helps keep the tool light at 1.32 lb, making it easier to guide during repeated bench, fixture, and maintenance grinding tasks.

FAQs:

• Q: What accessories can be used with this Dotco die grinder?
  A: This model is listed with a 6mm collet and an abrasive capacity of 3/4" carbide burrs and 1-1/2" mounted wheels. Any accessory used with the tool must fit the collet properly and be rated at or above 20,000 RPM.
• Q: What does the OH designation mean on 12L2081-01M6OH?
  A: The OH version includes a 4 ft overhose for additional noise suppression. It is used on rear-exhaust tools to help route exhaust air farther away from the operator and work area.
• Q: Is this an inline die grinder or an angle die grinder?
  A: This is an inline die grinder, meaning the collet and body are aligned in a straight configuration. It is best for direct-access deburring, grinding, and finishing rather than 90-degree access into corners.
• Q: What air setup does this grinder require?
  A: The tool is performance rated at 90 PSI / 620 kPa and uses a 1/4" NPT air inlet with a minimum 1/4" hose I.D. A properly sized FRL and clean air supply help maintain speed and reduce premature wear.
• Q: Can this grinder be used for general garage work?
  A: Yes, when paired with the correct compressor, air line, and speed-rated accessories, it can be used for automotive repair, bracket cleanup, burr removal, and small metal finishing jobs. It is still a professional pneumatic tool, so accessory rating and PPE are especially important.
