Chicago Pneumatic Angle Die Grinder | CP3019-09AC | 9000 RPM | 1/4" (6 mm) Collet

Built for lower-speed angle-access deburring, contouring, grinding, and light chamfering, the Chicago Pneumatic CP3019-09AC angle die grinder delivers 9,000 RPM free speed for controlled abrasive contact 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 pneumatic motor provides useful power for repeated detail work in fabrication, maintenance, foundry, and production environments. The 90° angle-head configuration helps operators reach side surfaces, internal edges, casting features, and weld details that are awkward to approach with a straight die grinder.

The CP3019-09AC is the lowest-speed model in the CP3019 angle die grinder group, making it a practical choice when the accessory, workpiece material, or finish requirement calls for more control instead of maximum RPM. At 6.5" / 166 mm long and 1.1 lb / 0.5 kg, it gives operators a compact 90° pneumatic grinder for close-quarter work around fixtures, brackets, castings, panels, and machine parts. The safety lever starting system helps reduce accidental start risk, while the compact body with composite over-sleeve helps improve grip feel during repeated grinding and finishing tasks.

Features:

• 9,000 RPM free speed provides lower-speed control for deburring, contouring, grinding, cleaning, and light chamfering with compatible mounted accessories.
• 0.5 HP / 375 W pneumatic motor supports repeated abrasive work on metal parts, castings, fixtures, brackets, and repair components.
• 90° angle-head layout improves access to corners, internal edges, weld details, casting pockets, and side-facing surfaces.
• 1/4" / 6.0 mm collet capacity supports compatible shank-mounted accessories when the correct abrasive and shank size are selected.
• Compact 6.5" body helps operators work in close-quarter areas where longer angle die grinders may be harder to position.
• Safety lever starting system helps reduce accidental start risk during tool handling, setup, and daily operation.
• Composite over-sleeve provides a more manageable grip surface during repeated grinding and finishing work.
• Low sound pressure rating of 76 dB(A) helps reduce noise exposure compared with louder grinder configurations in the same tool category.

Applications:

• Metal fabrication: deburring drilled holes, cleaning cut edges, contouring small parts, and blending weld details with angle-head access.
• Foundry and casting cleanup: removing flash, parting lines, and minor surface defects from casting contours, pockets, and recessed 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 where a compact 90° pneumatic grinder improves access.

FAQs:

• Q: What is the CP3019-09AC best used for?
  A: The CP3019-09AC is used for controlled angle-access deburring, contouring, grinding, cleaning, and light chamfering with compatible mounted accessories. Its 9,000 RPM speed makes it useful when lower abrasive speed and control are more important than fast stock removal.
• Q: How is the CP3019-09AC different from the 12,000 and 20,000 RPM CP3019 models?
  A: The CP3019-09AC runs at 9,000 RPM, making it the slower, more controlled option in the CP3019 angle die grinder range. Choose higher-speed models when the accessory and material call for faster cutting or lighter high-RPM finishing.
• Q: What collet size does this grinder use?
  A: The supplied title and catalog-style data list a 1/4" / 6.0 mm collet for SKU 6151702660. Match the accessory shank to the installed collet before use, and confirm the collet setup when ordering replacement collets or specialty burrs.
• Q: What air supply does the CP3019-09AC require?
  A: The catalog-style data lists 6 CFM / 3 l/s air consumption at load with a 1/4" NPT air inlet and 90 PSI / 6.3 bar working pressure. Use clean, regulated air through the recommended minimum hose diameter to help maintain tool speed and reduce premature wear.
• 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 9,000 RPM free speed. Always confirm shank size, accessory type, workpiece material, and the accessory manufacturer's safety rating before use.
