Built for compact wheel-based grinding, cutting, and surface preparation, the Chicago Pneumatic CP3019-18AES3 angle grinder delivers 18,000 RPM free speed for work with compatible 3" / 75 mm abrasive wheels. Unlike collet-style die grinders that use burrs or mounted points, this model uses a guarded wheel setup with a 3/8"-24 UNF output spindle thread, making it suitable for small-area grinding and cutting where a full-size 4-1/2" or 5" grinder would be too large. The 0.5 HP / 375 W governed pneumatic motor supports productive material removal while keeping the tool compact for close-access work.
The CP3019-18AES3 is part of Chicago Pneumatics CP3019 compact angle grinder range, a series built around small wheel capacities, governed motor control, and a streamlined lever start. Its extended-style body provides additional reach compared with shorter 3" wheel grinders, while the aluminum housing and insulating composite over-housing help improve handling during repeated repair, finishing, and maintenance tasks. The band-style guard and keyed swiveling guard arrangement support wheel guarding for small abrasive wheel applications.

Features:
- 18,000 RPM free speed supports compact grinding and cutting with compatible 3" abrasive wheels.
- 0.5 HP / 375 W governed motor helps support controlled wheel speed during small-area grinding and surface preparation.
- 3" / 75 mm wheel capacity gives access to tighter repair areas where larger angle grinders may be difficult to position.
- 3/8"-24 UNF output spindle thread supports compatible small wheel mounting hardware when the correct guard and abrasive accessory are selected.
- Extended-style body gives additional reach for brackets, recessed edges, seams, tabs, and repair sections.
- Band-style guard with keyed swiveling guard setup provides guarded wheel operation for small abrasive wheel applications.
- Aluminum housing with insulating composite over-housing helps improve handling during repeated grinding and cutting tasks.
- Streamlined lever starting system supports practical daily use in fabrication, repair, and maintenance environments.
Applications:
- Metal fabrication: small-area grinding, edge cleanup, weld touch-up, and localized surface preparation.
- Body shop and vehicle repair: cutting and grinding around brackets, tabs, repair panels, and tight access points.
- Industrial maintenance and MRO: cleanup on guards, covers, fixtures, brackets, and repair components where a compact wheel grinder is preferred.
- Workshop repair: wheel-based cutting and grinding on small metal parts, hardware, and fabricated assemblies.
- Production finishing: localized burr removal and surface correction when a 3" guarded abrasive wheel fits the part geometry.
FAQs:
- Q: Does the CP3019-18AES3 use a collet?
A: No. The supplied title lists a 15/64" collet, but the CP3019-18AES3 is a 3" wheel angle grinder with a 3/8"-24 UNF output spindle thread. It should not be treated as a collet-style die grinder. - Q: What wheels can be used with this grinder?
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 tool's 18,000 RPM free speed. - Q: What air supply does the CP3019-18AES3 require?
A: Chicago Pneumatic lists 19 CFM / 9.1 l/s air consumption at load and 10 CFM / 4.9 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: How is this different from a 4-1/2" or 5" angle grinder?
A: This model uses a smaller 3" wheel for tighter access and localized work. Larger wheel grinders cover more area per pass, while the CP3019-18AES3 is better suited to smaller cuts, detail grinding, and confined repair areas. - Q: Does this model have an auto balancer or spindle lock?
A: No. The CP3019-18AES3 is listed without an auto balancer and without a spindle lock. Follow the manufacturer's accessory-change procedure and use the correct wheel mounting hardware.
