Cleco C3120A5-58OH High-Performance Right-Angle Grinder | 5" Wheel | 1.7 HP | 12,000 RPM | 3.03" Head | Rear Exhaust

Built for weld cleanup, edge grinding, abrasive cutting, and metal surface preparation, the Cleco C3120A5-58OH right-angle grinder delivers 1.7 HP of pneumatic power for fast material removal on steel, fabrication parts, repair brackets, and shop-built assemblies. Its 5" wheel capacity gives operators more abrasive coverage than a 4-1/2" grinder while still keeping the tool compact enough for handheld control. The 12,000 RPM free speed supports efficient grinding and cutting when matched with accessories rated at or above the tool speed.

The C3120A5-58OH uses a 5/8"-11 spindle thread, a common grinder spindle size for compatible abrasive wheels and flange hardware. Its 3.03" head height helps the grinder work around frames, weldments, fixtures, and other restricted areas where larger grinders may be difficult to position. Rear exhaust routes spent air away from the work surface, while the quick-change spindle lock, anti-vibration handle, composite housing, and 270-degree adjustable guard support practical daily use in fabrication, maintenance, welding, and repair environments.

FAQs:

• Q: What is the main difference between the C3120A5-58OH and the C3120A45-58OH?
  A: The C3120A5-58OH is the 5" wheel version, while the C3120A45-58OH is the 4-1/2" wheel version. Both use a 5/8"-11 spindle thread, but the guard and wheel capacity differ.
• Q: What wheel type should be used with this grinder?
  A: This grinder is used with compatible Type 27, Type 27 threaded hub, or Type 1 abrasive discs when the disc size, spindle thread, guard, flange setup, and RPM rating match the tool. Always confirm wheel compatibility before mounting an accessory.
• Q: Why does the 12,000 RPM speed rating matter?
  A: The abrasive accessory must be rated at or above 12,000 RPM. A wheel with a lower maximum operating speed is unsafe, even if the wheel diameter and spindle thread appear to fit.
• Q: What does rear exhaust do on this Cleco grinder?
  A: Rear exhaust sends spent air toward the back of the tool instead of directly onto the workpiece. This helps keep airflow away from the grinding area and can improve visibility during cutting and cleanup work.
• Q: What size air hose should be used with the C3120A5-58OH?
  A: The manufacturer lists a 1/2" minimum hose I.D. for this model. Using undersized hose can restrict airflow and reduce grinder output under load.
