Chicago Pneumatic Angle Die Grinder | CP3019-20ACFE | 20000 RPM | 1/4" (6 mm) Collet

Built for high-speed detail grinding in tight access points, the Chicago Pneumatic CP3019-20ACFE angle die grinder delivers 20,000 RPM free speed for fast deburring, contouring, cleaning, and light chamfering 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 drilled holes, weld details, casting flash, or machined edges. The short 90° angle body helps operators reach corners, internal edges, and close-quarter surfaces where a straight grinder or longer angle grinder may be difficult to position.

The CP3019-20ACFE uses a front exhaust configuration, meaning spent air exits near the tool head instead of through the rear of the handle. This layout can help when rear exhaust flow or hose routing would interfere with the operator’s grip, access angle, or nearby fixtures. At approximately 6.54" / 166 mm long and 1.12 lb / 0.51 kg, this model gives fabrication, foundry, maintenance, and production users a compact high-speed angle die grinder for repeated work in crowded assemblies and detail areas.

Features:

• 20,000 RPM free speed supports fast deburring, contouring, grinding, cleaning, and light chamfering with compatible mounted accessories.
• 0.5 HP / 375 W governed motor helps maintain productive abrasive speed during repeated contact with burrs, mounted points, abrasive wheels, and flap wheels.
• Short 90° angle-head layout improves access to corners, internal edges, weld details, casting features, and tight work areas.
• Front exhaust configuration directs spent air near the tool head instead of out the rear, which can help when rear exhaust flow would interfere with positioning.
• 1/4" / 6.0 mm collet capacity supports compatible shank-mounted accessories when the correct abrasive and shank size are selected.
• Highest durability in demanding applications, up to 2,000 hours maintenance intervals.
• Streamlined safety lever helps reduce accidental start risk during tool handling, setup, and daily operation.
• Compact body with an insulating composite over-housing provides a manageable grip surface during repeated grinding and finishing work.

Applications:

• Metal fabrication: fast deburring of drilled holes, cleaning cut edges, contouring parts, and blending small weld areas with compact angle-head access.
• Foundry and casting cleanup: removing flash, parting lines, and minor 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, 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 where a short high-speed 90° grinder improves access.

FAQs:

• Q: What is the CP3019-20ACFE best used for?
  A: The CP3019-20ACFE is used for compact angle-access deburring, grinding, contouring, cleaning, and light chamfering with compatible mounted accessories. Its short body helps when the work area is close, crowded, or difficult to approach with a longer angle grinder.
• Q: How is the CP3019-20ACFE different from the CP3019-12ACFE?
  A: Both models share the short front-exhaust angle configuration, but the CP3019-20ACFE runs at 20,000 RPM while the CP3019-12ACFE runs at 12,000 RPM. Choose the 20,000 RPM version for faster work with smaller accessories and lighter contact, and choose the 12,000 RPM version when lower speed and more controlled abrasive contact are preferred.
• Q: What does "front exhaust" mean on this grinder?
  A: Front exhaust means the tool vents spent air near the grinder head instead of through the rear of the handle. This can help when rear exhaust air or hose routing would interfere with the operator's grip, access angle, or nearby fixtures.
• Q: What air supply does the CP3019-20ACFE 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 a clean, regulated air system capable of maintaining 90 PSI / 6.3 bar at the tool through the recommended 0.31" / 8 mm minimum hose diameter.
• Q: Can this grinder use any mounted point, burr, or flap wheel?
  A: No. The accessory must match the installed collet size and must have a maximum operating speed equal to or higher than the grinder's 20,000 RPM free speed. Always confirm shank size, accessory type, workpiece material, and the accessory manufacturer's safety rating before use.
