Chicago Pneumatic Angle Grinder | CP3650-120AH5V | 12000 RPM | 5" Wheel Size

Built for 5" wheel grinding, cutting, and surface preparation where lower vibration and wheel balance matter, the Chicago Pneumatic CP3650-120AH5V Angle Grinder delivers 12,000 RPM free speed for productive work with properly rated abrasive wheels. Its 2.4 HP / 1800 W governed pneumatic motor helps maintain wheel speed during weld cleanup, edge grinding, cutting, and surface preparation. The 5" / 125 mm wheel capacity gives users a compact grinding path for tighter access than larger 6" or 7" grinders, while the Hexa output spindle shaft requires the correct compatible wheel mounting hardware instead of standard threaded spindle assumptions.

The CP3650-120AH5V is part of Chicago Pneumatic's CP3650 Series and includes an autobalancer, a built-in balancing system that helps reduce vibration as the wheel runs. This is especially useful during repeated grinding passes where vibration can affect control, finish quality, and operator fatigue. A keyless pull-and-turn swiveling guard provides 360° rotation with indexed positions, while the spindle lock button helps speed up abrasive disc changes. The steel swiveling air inlet helps reduce hose pull, and the aluminum body with composite over-sleeve gives the tool a manageable grip surface during production, repair, and MRO work.

Features:

• 12,000 RPM free speed supports fast grinding and cutting with compatible 5" abrasive wheels.
• 2.4 HP / 1800 W governed motor helps maintain wheel speed during weld cleanup, cutting, edge grinding, and surface preparation.
• Autobalancer helps reduce vibration during repeated grinding passes, improving control compared with non-balanced configurations.
• Hexa output spindle shaft supports compatible Hexa wheel mounting hardware for applications requiring this output style.
• 5" / 125 mm wheel capacity gives users more coverage than a 4-1/2" grinder while staying compact for close work areas.
• Keyless pull-and-turn swiveling guard offers 360° rotation with 15 guard positions for faster guard adjustment.
• Spindle lock button helps reduce abrasive disc change time between cutting and grinding operations.
• Steel swiveling air inlet and vibration-damping side handle help improve handling around frames, weldments, fixtures, and workpieces.

Applications:

• Metal fabrication: grinding weld seams, cleaning cut edges, removing burrs, and preparing steel or aluminum parts for finishing.
• Industrial maintenance and MRO: surface cleanup, rust removal, wheel-based cutting, and repair work on guards, covers, fixtures, and plant hardware.
• Frame and equipment service: grinding brackets, supports, tabs, repair plates, and structural components where a 5" wheel is appropriate.
• Production grinding cells: repeated wheel-based grinding where the autobalancer can help reduce vibration during longer work cycles.
• Workshop and field service: pneumatic grinding and cutting for users with a compressed-air system capable of supporting the tool's high air demand.

FAQs:

• Q: What wheels can be used with the CP3650-120AH5V?
  A: Use compatible 5" / 125 mm grinding or cutting wheels that match the Hexa output spindle shaft, guard configuration, and work application. The wheel's maximum operating speed must equal or exceed the grinder's 12,000 RPM free speed.
• Q: What does the autobalancer do?
  A: The autobalancer helps reduce vibration by improving wheel balance while the grinder is running. This can improve control during repeated grinding passes and helps distinguish this model from non-autobalancer CP3650 variants.
• Q: How is the CP3650-120AH5V different from the CP3650-120AB5V?
  A: Both are 5", 12,000 RPM CP3650 angle grinders with autobalancers, but the CP3650-120AH5V uses a Hexa output spindle shaft. The CP3650-120AB5V uses a 5/8"-11 spindle thread, so wheel mounting hardware must be selected for the correct spindle style.
• Q: What air supply does this angle grinder require?
  A: Chicago Pneumatic lists 63.1 CFM / 29.8 l/s air consumption at load and 37.3 CFM / 17.6 l/s at free speed. Use a compressed-air system that can maintain 90 PSI / 6.3 bar at the tool through a minimum 1/2" / 13 mm hose.
• Q: Is this grinder the right choice for lower-vibration 5" grinding?
  A: Yes, when the application calls for a 5" pneumatic angle grinder with an autobalancer and the correct Hexa-compatible wheel setup. For standard threaded wheel hardware, compare against CP3650 models with 5/8"-11 or M14 spindle configurations.
