Chicago Pneumatic Air Pencil Grinder | CP3000-600CR 3mm | 60000 RPM | 1/8" (3 mm) Collet

Built for precision deburring, fine finishing, and small-detail grinding, the Chicago Pneumatic CP3000-600CR 3mm Air Pencil Grinder delivers 60,000 RPM free speed for high-speed work with miniature carbide burrs, mounted points, and compatible abrasive accessories. Unlike full-size die grinders, a pencil grinder is a slim, lightweight air grinder made for close-control detail work rather than heavy stock removal. Its manufacturer-listed 3 mm collet capacity supports small shank-mounted accessories for fine edge cleanup, parting-line removal, mold finishing, and detail correction on metal, plastic, composites, and machined components.

The CP3000-600CR uses a compact 6.02" / 153 mm steel body and weighs only 0.31 lb / 0.14 kg, making it easier to guide with fingertip control in toolrooms, finishing benches, production cells, and repair areas. A rotary valve provides smooth power adjustment, while the grooved housing improves grip control during precise work. Chicago Pneumatic also lists a silencer hose included with this model, helping reduce operating noise during repeated high-speed finishing tasks.

Applications:

• Metal fabrication: fine deburring around drilled holes, small slots, cut edges, and tight contours where a larger grinder would remove too much material.
• Machining and production finishing: cleaning small features, removing minor burrs, and correcting sharp edges on machined components.
• Composite and plastic trimming: controlled finishing on small edges and detail areas when the accessory is suitable for the material.
• Repair and maintenance benches: precision cleanup on brackets, small hardware, instrument parts, and light-duty repair components.

FAQs:

• Q: What is the CP3000-600CR 3mm best used for?
  A: This air pencil grinder is best used for precision deburring, fine finishing, and small-detail grinding. Its 60,000 RPM speed and pencil-style body make it suitable for detailed work that requires control rather than aggressive material removal.
• Q: Is this a pencil grinder or a standard die grinder?
  A: It is a pencil grinder. Pencil grinders are smaller, lighter, and built for precision control with miniature accessories, while standard die grinders are larger tools used for heavier deburring and grinding.
• Q: What collet size does this model use?
  A: Chicago Pneumatic’s current product data identifies SKU 6151600330 as CP3000-600CR 3mm with a 3 mm collet capacity. The supplied title lists 15/64" collet, so the collet should be verified before publishing or matching accessories.
• Q: What air supply does this pencil grinder require?
  A: Chicago Pneumatic lists 5.5 CFM / 2.6 l/s air consumption at load, 7.6 CFM air consumption at free speed, and 90 PSI / 6.3 bar working pressure. Use clean, regulated air through the recommended 0.25" / 6 mm minimum hose diameter.
• Q: Can this grinder use any small burr or mounted point?
  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 60,000 RPM free speed. Always confirm shank size, accessory type, workpiece material, and accessory speed rating before use.
