Dotco 12L2674-5A Multiple Extension Die Inline Grinder | 12-26 Series | 0.9 HP | 18000 RPM | 1/4" Collet | Rear Exhaust

When grinding and deburring work is located beyond the reach of a conventional die grinder, the Dotco 12L2674-5A Multiple Extension Inline Die Grinder provides an extended pneumatic platform for accessing recessed surfaces, internal cavities, and deep features in fabricated or machined components. Its 0.9 HP motor supplies power for material removal and surface conditioning, while the 18,000 RPM free speed supports controlled use of compatible mounted abrasives and rotary cutting accessories.

The 1/4" collet accommodates commonly used industrial shank-mounted accessories, allowing the tool to perform deburring, weld blending, casting cleanup, and localized grinding operations. As part of the 12-26 Series, the 12L2674-5A combines its multiple extension configuration with rear exhaust, which routes discharged air away from the immediate abrasive contact area. This configuration serves fabrication shops, production facilities, foundries, and maintenance departments where both reach and controlled accessory positioning are important.

Applications:

• Metal fabrication shops removing burrs, blending welds, and finishing recessed surfaces within fabricated structures.
• Foundry and casting operations cleaning flash, gates, and accessible internal features on cast components.
• Industrial maintenance and MRO departments performing localized grinding and surface preparation inside machinery assemblies.
• Production manufacturing stations deburring machined openings, deep features, and components that require additional grinder reach.
• Equipment repair and component rework involving controlled use of 1/4" shank mounted abrasives and carbide burrs.

FAQs:

• Q: When should I choose a multiple extension die grinder instead of a standard inline grinder?
  A: A multiple extension grinder is useful when the abrasive contact point is located deeper inside a component or assembly than a standard-length tool can comfortably reach. The extended configuration allows the operator to position compatible accessories farther into recessed work areas.
• Q: Which accessory shank size fits the Dotco 12L2674-5A?
  A: This grinder is equipped with a 1/4" collet and accepts compatible accessories with 1/4" shanks. Always confirm both accessory dimensions and maximum operating speed before installation.
• Q: Can I use an abrasive accessory rated below 18,000 RPM?
  A: No. Every abrasive accessory used with this tool must have a maximum operating speed equal to or greater than 18,000 RPM. Operating an accessory above its rated speed creates a serious safety hazard.
• Q: What types of material-removal work can this grinder perform?
  A: When fitted with the correct accessory, the tool can be used for deburring, weld blending, casting cleanup, localized grinding, and surface preparation in areas that benefit from additional reach.
• Q: Where does the exhaust air discharge on the 12L2674-5A?
  A: This model uses rear exhaust, directing discharged air toward the back of the tool rather than across the immediate abrasive contact area.
