Cleco C3120A5-M14OH Right Angle Grinder | 5" Wheel Dia. | 1.7 HP | 12000 RPM | 3.03" Head | Rear Exhaust

Built for weld blending, edge cleanup, and material removal with 5-inch abrasive wheels, the Cleco C3120A5-M14OH Right Angle Grinder combines a 1.7 HP pneumatic motor with 12,000 RPM free speed to remove metal quickly while keeping the tool compact enough for fabrication benches, repair bays, and production work areas. The 5" wheel capacity supports common grinding and cutting accessories, while the M14 x 2 spindle thread matches compatible threaded-hub abrasives used in many metric grinding setups.

This C31 Series grinder uses a 3.03" head height to help operators work around weldments, brackets, and tight part geometry where larger grinders can be difficult to position. The rear exhaust routes air away from the work area, helping reduce debris blowback toward the abrasive contact point. Its quick-change spindle lock and adjustable guard make accessory changes and wheel positioning more practical during repeated grinding, deburring, and surface preparation tasks.

Applications:

• Metal fabrication: Grinding welds, smoothing cut edges, and preparing steel components before finishing or coating.
• Welding shops: Blending beads, removing spatter, and cleaning joint areas with properly rated 5" abrasive accessories.
• Transportation equipment manufacturing: Surface cleanup and bracket-area grinding on frames, panels, and fabricated assemblies.
• Industrial maintenance and MRO: Removing burrs, corrosion, and excess material from machinery parts during repair work.
• Pipe and structural work: Grinding around weldments, flanges, and fabricated joints where a compact right angle head improves access.

FAQs:

• Q: What abrasive wheels can be used with the Cleco C3120A5-M14OH?
  A: Use only compatible 5" abrasive wheels that match the M14 x 2 spindle thread and are rated at or above the grinder’s 12,000 RPM free speed. Always verify wheel type, guard compatibility, and manufacturer safety requirements before use.
• Q: What does rear exhaust mean on this grinder?
  A: Rear exhaust means spent air exits toward the back of the tool instead of near the grinding head. This helps keep exhaust air away from the immediate contact area and can reduce debris disturbance on the work surface.
• Q: Is this a die grinder or a wheel grinder?
  A: This is a right angle wheel grinder, not a collet-style die grinder. It is intended for compatible abrasive wheels rather than mounted points, carbide burrs, or other shank-mounted accessories.
• Q: What air hose size should be used?
  A: The listed minimum hose I.D. is 1/2". Using an undersized hose can restrict airflow and reduce grinding performance, especially under sustained material removal.
• Q: Can this grinder be used for automotive or garage work?
  A: Yes, when the compressor, hose, and abrasive accessories are properly matched. Its 1.7 HP output is better suited to serious repair, fabrication, and shop use than light-duty hobby grinding.
