Cleco 12S2674-2C Inline Die Grinder | 12-26 Series | 0.9 HP | 18,000 RPM | 3/8"-24 External Thread | Composite Housing | Rear Exhaust

When you need extended reach for deburring, blending, and mounted abrasive work inside deeper cavities, the Cleco 12S2674-2C Inline Die Grinder gives operators a high-speed material removal tool with a 0.9 HP motor and 18,000 RPM free speed for controlled work on metal edges, castings, weld areas, and machined components. This 12-26 Series multiple-extension grinder uses a 3/8"-24 external thread termination for compatible threaded abrasive accessories, while the 14.50" extension helps reach areas that standard inline die grinders may not access comfortably.

The rear exhaust directs spent air away from the work surface, helping reduce chip and abrasive dust disturbance during close-detail grinding. A composite housing keeps the tool manageable for extended handling, and multiple industrial bearings support balance and power transfer through the extended spindle assembly. All tool performance is rated at 90 PSI / 620 kPa air pressure.

• 0.9 HP motor output supports controlled material removal with compatible cone or plug wheel abrasives.
• 18,000 RPM free speed provides the surface speed needed for deburring, edge cleanup, and blending with properly rated mounted abrasives.
• 3/8"-24 external thread termination accepts compatible threaded abrasive accessories for cone or plug wheel work.
• Multiple industrial bearings help maintain balance and transfer power through the extended spindle assembly.
• Rear exhaust directs air away from the work area to help keep grinding debris from being blown forward across the part.
• Composite housing reduces unnecessary tool weight while maintaining a practical inline grip for controlled handling.
• Rated at 90 PSI / 620 kPa and matched to a minimum 5/16" hose I.D. for proper pneumatic supply setup.

Made in USA:

Applications:

• Metal fabrication and weld shops — blending weld transitions, cleaning internal corners, and reaching recessed areas with threaded mounted abrasives.
• Foundry and casting cleanup — removing flash, parting lines, and localized surface defects on cast metal components.
• Industrial maintenance and MRO — spot grinding, edge cleanup, and repair work on machinery parts where access is limited.
• Toolroom and machine shop work — deburring machined features, ports, slots, and interior surfaces that require an extended inline grinder.
• Automotive, fleet, and equipment repair — cleaning brackets, housings, frame sections, and component cavities with compatible cone or plug wheels.

FAQs:

• Q: What accessories fit the Cleco 12S2674-2C?
  A: This model uses a 3/8"-24 external thread termination and is listed with a 1.25" cone or plug wheel abrasive capacity. Always confirm the accessory thread, diameter, and maximum RPM rating before mounting it on the tool.
• Q: What does the 14.50" extension do?
  A: The extension increases reach between the operator’s hand position and the abrasive contact point. This helps when working inside cavities, around obstructions, or on deeper surfaces that a standard-length inline grinder cannot reach easily.
• Q: Can this grinder be used with a standard 1/4" collet burr?
  A: This specific SKU is the “C” termination version with a 3/8"-24 external thread, not the 1/4" collet configuration. Choose the correct 12-26 Series variation if your application requires collet-mounted carbide burrs.
• Q: Why does rear exhaust matter on an inline die grinder?
  A: Rear exhaust sends air away from the work surface and abrasive contact point. That can help reduce debris blowback and improve control when grinding in close quarters.
• Q: What air setup should be used with this tool?
  A: Cleco rates tool performance at 90 PSI / 620 kPa and lists a minimum hose I.D. of 5/16" / 7.9 mm. Use clean, regulated, lubricated air and avoid undersized hose or fittings that can restrict tool performance.
