Built for demanding 7" wheel grinding, cutting, weld cleaning, contouring, and deburring, the Chicago Pneumatic CP3850-85AH7VE Angle Grinder delivers 8,500 RPM free speed for productive work with properly rated abrasive wheels. Its 2.8 HP / 2,100 W governed pneumatic motor provides high output for industrial maintenance, fabrication, repair, and metal preparation tasks, while the 7" / 180 mm wheel capacity gives operators wider coverage than compact 4-1/2", 5", and 6" grinder formats. This AH-version uses a Hexa output spindle, so wheel mounting hardware must be matched to the Hexa spindle configuration rather than a standard 5/8"-11 threaded setup.
The CP3850-85AH7VE is part of Chicago Pneumatic's CP3850 Series, a 7" and 9" Pneumatic Angle Grinder family built for rough industrial use and high power-to-weight performance. The built-in autobalancer helps reduce vibration by improving wheel balance while the grinder is running, and Chicago Pneumatic's spiral bevel gear design supports a 2,000-hour maintenance interval. A spindle lock button supports faster abrasive wheel changes, while the 360° adjustable air exhaust with integrated muffler helps manage exhaust direction during grinding and cutting work.

Features:
- 8,500 RPM free speed supports productive 7" grinding and cutting with compatible abrasive wheels.
- 2.8 HP / 2,100 W governed motor provides high output for weld cleaning, contouring, deburring, surface preparation, and repair work.
- Autobalancer helps reduce vibration during repeated grinding passes by improving wheel balance while the tool is running.
- Hexa output spindle supports compatible Hexa wheel mounting hardware for applications requiring this spindle configuration.
- Spiral bevel gear design helps reduce vibration and torque transmission stress while supporting a 2,000-hour maintenance interval.
- Spindle lock button helps reduce abrasive wheel change time between grinding, cutting, and cleanup operations.
- 360° adjustable exhaust with integrated muffler helps the operator direct spent air away from the work area.
- Double streamlined safety lever helps reduce accidental start risk while allowing practical one-hand engagement.
Applications:
- Industrial maintenance and MRO: grinding, cutting, weld cleaning, and repair work on plant equipment, fixtures, guards, and structural components.
- Metal fabrication: weld seam removal, edge grinding, contouring, deburring, and surface preparation on steel assemblies and fabricated parts.
- Heavy repair work: grinding frames, supports, brackets, repair plates, and larger service components where a 7" wheel is appropriate.
- Shipyard, rail, and equipment service: air-powered wheel grinding for rugged applications where high output and wheel coverage are required.
- Workshop and field service: pneumatic grinding and cutting for users with an air system capable of supporting the tool's 77 CFM load demand.
FAQs:
- Q: What wheels can be used with the CP3850-85AH7VE?
A: Use compatible 7" / 180 mm abrasive wheels that match the Hexa output spindle, guard configuration, wheel mounting hardware, and work application. The wheel's maximum operating speed must equal or exceed the grinder's 8,500 RPM free speed. - Q: What does the Hexa output spindle mean?
A: The Hexa output spindle is a non-standard-thread spindle configuration that requires compatible Hexa wheel mounting hardware. Do not assume this model uses the 5/8"-11 UNC spindle found on AB-series CP3850 variants. - 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 configurations. - Q: What air supply does this angle grinder require?
A: Chicago Pneumatic lists 77 CFM / 36 l/s air consumption at load and 36 CFM / 17 l/s at free speed. Use a compressed-air system that can maintain 90 PSI / 6.3 bar at the tool through the recommended 5/8" / 16 mm minimum hose diameter. - Q: How is the CP3850-85AH7VE different from the CP3850-85AB7VE?
A: Both are 7", 8,500 RPM CP3850 angle grinders with autobalancers, but the CP3850-85AH7VE uses a Hexa output spindle. The CP3850-85AB7VE uses a 5/8"-11 UNC spindle thread, so wheel mounting hardware must be selected for the exact model.
