Chicago Pneumatic Angle Grinder | CP3019-20AES2 | 20000 RPM | 2" Wheel Size

Built for very small wheel-based grinding and cutting in tight work areas, the Chicago Pneumatic CP3019-20AES2 Angle Grinder delivers 20,000 RPM free speed for use with compatible 2" / 50 mm abrasive wheels. This model is not a collet-style die grinder; it uses a guarded wheel setup with a 3/8"-24 UNF output spindle thread, making it useful for localized cutting, edge cleanup, spot grinding, and detail surface preparation where a 3", 4-1/2", or 5" grinder would be too large. The 0.5 HP / 375 W governed pneumatic motor helps manage wheel speed during compact grinding work while keeping the tool light enough for controlled positioning.

The CP3019-20AES2 is the 2" wheel model in Chicago Pneumatic's CP3019 Compact Angle Grinder range. Its long body layout gives extra reach into brackets, tabs, repair sections, narrow seams, and recessed edges, while the aluminum housing with composite over-sleeve helps improve handling during repeated use. The band-style guard and keyed swiveling guard arrangement support guarded operation for small abrasive wheel applications, and the safety lever starting system helps reduce accidental start risk during setup and positioning.

• 0.5 HP / 375 W governed motor helps control wheel speed during compact grinding, cutting, and surface preparation tasks.
• 2" / 50 mm wheel capacity gives access to narrow work areas where larger wheel grinders may not fit.
• 3/8"-24 UNF output spindle thread supports compatible small-wheel mounting hardware when the correct guard and abrasive accessory are selected.
• Long body configuration helps reach brackets, tabs, seams, repair sections, and recessed details while retaining a compact wheel format.
• Band-style guard with keyed swiveling guard setup supports guarded operation for small abrasive wheel applications.
• Aluminum housing with composite over-sleeve helps improve handling during repeated grinding and cutting work.
• Safety lever starting system helps reduce accidental start risk during tool handling, setup, and positioning.

Applications:

• Body shop and vehicle repair: compact cutting and grinding around brackets, tabs, panel sections, and narrow repair areas.
• Metal fabrication: localized edge cleanup, small cut line finishing, weld touch-up, and surface preparation on tight part geometry.
• Industrial maintenance and MRO: wheel-based cleanup on guards, covers, fixtures, brackets, and small repair components.
• Workshop repair: small-wheel pneumatic grinding and cutting on hardware, light fabricated assemblies, and service parts.
• Production finishing: localized burr removal and surface correction where a 2" guarded abrasive wheel fits the part better than a larger grinder.

FAQs:

• Q: Is the CP3019-20AES2 a die grinder?
  A: No. The CP3019-20AES2 is a 2" wheel angle grinder with a 3/8"-24 UNF output spindle thread. It is used with compatible abrasive wheels, not collet-mounted burrs or mounted points.
• Q: What wheels can be used with this model?
  A: Use compatible 2" / 50 mm abrasive wheels that match the 3/8"-24 UNF spindle setup, guard configuration, and work application. The wheel's maximum operating speed must equal or exceed the grinder's 20,000 RPM free speed.
• Q: How is the CP3019-20AES2 different from the CP3019-20AES3?
  A: Both models run at 20,000 RPM and use a compact long-body angle grinder format, but the CP3019-20AES2 is built for 2" / 50 mm wheels while the CP3019-20AES3 is built for 3" / 75 mm wheels. Choose the 2" model when access space is tighter or the work area is smaller.
• Q: What air supply does the CP3019-20AES2 require?
  A: Chicago Pneumatic lists 21 CFM / 10 l/s air consumption at load and 13 CFM / 6.5 l/s at free speed. Use clean, regulated air at 90 PSI / 6.3 bar through the recommended 0.31" / 8 mm minimum hose diameter.
• Q: Does this grinder have a spindle lock or auto balancer?
  A: No. The CP3019-20AES2 is listed without a spindle lock and without an auto balancer. Follow the manufacturer's accessory-change procedure and use wheel mounting hardware that matches the 3/8"-24 UNF output spindle thread.
