Chicago Pneumatic Angle Grinder | CP3019-20AES3 | 20000 RPM | 3" Wheel Size

Built for compact wheel-based grinding and cutting where higher speed is needed, the Chicago Pneumatic CP3019-20AES3 angle grinder delivers 20,000 RPM free speed for use with compatible 3" / 75 mm abrasive wheels. This model uses a guarded wheel setup rather than a collet-mounted burr system, making it suitable for localized cutting, edge cleanup, surface preparation, and small-area grinding. The 3/8"-24 UNF output spindle thread supports compatible wheel mounting hardware, while the 0.5 HP / 375 W governed pneumatic motor helps control speed during demanding compact-grinder work.

The CP3019-20AES3 is the 20,000 RPM extended 3" wheel model in Chicago Pneumatic's CP3019 Compact Angle Grinder range. Compared with the CP3019-18AES3, this version runs at a higher free speed while retaining the same compact 3" wheel format and extended body style. The insulating composite over-sleeve improves handling comfort, the rear-style body layout provides reach into tight areas, and the streamlined lever start supports practical operation in repair, fabrication, production, and MRO environments.

Features:

• 20,000 RPM free speed supports fast localized grinding and cutting with compatible 3" abrasive wheels.
• 0.5 HP / 375 W governed motor helps control wheel speed during compact grinding, cutting, and surface preparation tasks.
• 3" / 75 mm wheel capacity gives access to smaller work areas where larger angle grinders may be difficult to position.
• 3/8"-24 UNF output spindle thread supports compatible wheel mounting hardware when the correct abrasive accessory and guard setup are selected.
• Extended body style helps reach brackets, tabs, seams, repair sections, and recessed areas 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 insulating composite over-sleeve helps improve operator handling during repeated grinding and cutting work.
• Streamlined lever starting system provides practical tool control during daily fabrication, repair, and maintenance use.

Applications:

• Metal fabrication: localized grinding, edge cleanup, cut line finishing, and small-area weld touch-up.
• Body shop and vehicle repair: cutting and grinding around brackets, tabs, panel sections, and tight repair areas.
• Industrial maintenance and MRO: wheel-based cleanup on guards, covers, fixtures, brackets, and small repair components.
• Production finishing: removing localized burrs, correcting small surfaces, and preparing part edges where a 3" wheel fits the geometry.
• Workshop repair: compact pneumatic cutting and grinding on small metal parts, hardware, and fabricated assemblies.

FAQs:

• Q: Is the CP3019-20AES3 a die grinder or a wheel grinder?
  A: The CP3019-20AES3 is a 3" wheel angle grinder. It uses a 3/8"-24 UNF output spindle thread for compatible wheel mounting hardware, not a collet-mounted burr setup.
• Q: What wheels can be used with this model?
  A: Use compatible 3" / 75 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 CP3019-20AES3 different from the CP3019-18AES3?
  A: Both models use a 3" wheel and extended compact angle-grinder format, but the CP3019-20AES3 runs at 20,000 RPM while the CP3019-18AES3 runs at 18,000 RPM. Choose the 20,000 RPM model when the accessory and application call for the higher free speed.
• Q: What air supply does the CP3019-20AES3 require?
  A: Chicago Pneumatic lists 19 CFM / 9 l/s air consumption at load and 12 CFM / 6 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?
  A: No. The CP3019-20AES3 is listed without a spindle lock. Follow the manufacturer's accessory-change procedure and use the correct wheel mounting hardware for the 3/8"-24 UNF output spindle thread.
