Built for fast angle-access deburring, contouring, and light chamfering, the Chicago Pneumatic CP3019-20ACES Angle Die Grinder delivers 20,000 RPM free speed for rapid work with compatible carbide burrs, mounted points, abrasive wheels, and flap wheels. Its 1/4" / 6.0 mm collet supports common shank-mounted accessories, while the 0.5 HP / 375 W governed pneumatic motor helps maintain working speed when the abrasive is loaded against weld details, casting flash, drilled holes, or machined edges. The long angle grinder/sander configuration improves reach into recessed surfaces and around obstructions where a shorter angle die grinder may not approach the work cleanly.
The CP3019-20ACES is part of Chicago Pneumatic's CP3019 angle die grinder range, built around a compact body with an insulating composite over-sleeve for better handling during repeated grinding and finishing tasks. The 90° angle head makes it useful for corners, contours, internal edges, and side-access surfaces, while the safety lever starting system helps reduce accidental start risk. At 1.34 lb / 0.61 kg and 9.7" / 246 mm long, it gives fabrication, maintenance, and production users a lightweight tool for faster material removal in confined or awkward access points.

- Streamlined safety lever helps reduce accidental start risk during tool handling, setup, and daily operation.
- Compact body with an insulating composite over-housing supports improved grip feel and thermal insulation during repeated grinding work.
Applications:
- Metal fabrication: deburring drilled holes, cleaning cut edges, contouring parts, and blending small weld areas with angle-head access.
- Foundry and casting cleanup: removing flash, parting lines, and surface defects from casting contours, pockets, and internal features.
- Industrial maintenance and MRO: smoothing repair parts, cleaning brackets, preparing equipment components, and correcting fit-up surfaces.
- Machining and toolroom work: edge breaking, light chamfering, detail finishing, and contour correction on fixtures, dies, molds, and machined parts.
- Vehicle and equipment repair: working around brackets, panels, frames, and fabricated repair pieces in compressed-air service environments.
FAQs:
- Q: What is the CP3019-20ACES best used for?
A: The CP3019-20ACES is used for high-speed deburring, contouring, grinding, cleaning, and light chamfering with compatible mounted accessories. Its long 90° angle layout helps reach surfaces that are awkward for straight die grinders or shorter angle models. - Q: What does the 20,000 RPM speed mean for accessory selection?
A: The abrasive accessory must be rated for at least 20,000 RPM and must match the tool's collet size and mounting requirements. Never use an accessory with a lower maximum operating speed than the grinder. - Q: What collet size does this grinder use?
A: The catalog data lists a 1/4" / 6.0 mm collet for the CP3019-20ACES. Match the accessory shank to the installed collet before use, and confirm the collet setup when ordering replacement collets or specialty burrs. - Q: How is the CP3019-20ACES different from lower-speed CP3019 angle die grinders?
A: This model runs at 20,000 RPM, making it better suited for fast work with smaller accessories and lighter contact. Lower-speed CP3019 models provide more controlled abrasive contact when the accessory or material calls for reduced speed. - Q: What air supply does the CP3019-20ACES require?
A: Chicago Pneumatic lists 21 CFM / 10 l/s air consumption at load and 14 CFM / 6.5 l/s at free speed. Use a clean, regulated air system capable of maintaining 90 PSI / 6.3 bar at the tool through the recommended hose size.
