Dotco 12L2674-2A Multi Extension Inline Die Grinder | 12-26 Series | 0.9 HP | 18,000 RPM | Composite Housing | Rear Exhaust

Built for extended-reach grinding and deburring where standard die grinders cannot comfortably reach the work surface, the Dotco 12L2674-2A Multi Extension Inline Die Grinder combines a 0.9 HP pneumatic motor with an 18,000 RPM free speed for controlled material removal with compatible mounted abrasives. The multi extension layout helps position the accessory inside recessed areas, deep cavities, and obstructed assemblies commonly found in aerospace, fabrication, and production maintenance work.

Part of the Dotco 12-26 Series, this inline die grinder features a composite housing and rear exhaust configuration. The inline body supports straight access into the work area, while rear exhaust directs spent air away from the grinding surface to help keep airflow from disturbing chips, dust, or finishing work near the accessory.

• Production machining environments requiring secondary finishing after milling, drilling, or casting operations.
• Tool rooms and repair shops using extended-reach pneumatic grinders for controlled material removal.

FAQs:

• Q: What does “multi extension” mean on this Dotco die grinder?
  A: It refers to an extended tool configuration that places the working end farther from the operator’s hand. This helps reach deep cavities, recessed areas, and other locations where a standard inline die grinder may not fit.
• Q: Why choose a composite housing?
  A: Composite housing can help reduce tool weight compared with all-metal housing styles, which may be helpful when the grinder is used for repeated positioning or extended-reach work.
• Q: What does rear exhaust do?
  A: Rear exhaust routes spent air out the back of the tool instead of toward the accessory. This helps keep airflow from blowing directly across the surface being ground or finished.
• Q: Can any abrasive accessory be used at 18,000 RPM?
  A: No. Any mounted point, burr, or abrasive accessory must be rated for at least 18,000 RPM and must be compatible with the grinder’s mounting configuration. Always follow the accessory manufacturer’s speed and safety requirements.
