Chicago Pneumatic Straight Die Grinder | CP3119-060 | 6000 RPM | 1/4" Collet

Built for grinding, deburring, and contouring metal components, the Chicago Pneumatic CP3119-060 Straight Die Grinder gives maintenance crews and metalworking shops a controlled, high-power option for material removal with 1/4" shank accessories. Its 1/4" collet accepts common carbide burrs, mounted points, and abrasive stones, while the 1.2 hp / 900 W governed motor helps maintain cutting performance when the tool is working against burrs, casting flash, weld edges, and machined surfaces.

The manufacturer technical table lists this model at 5,500 RPM free speed, placing it in the lower-speed CP3119 range for applications where control and torque matter more than ultra-high spindle speed. Rear exhaust directs air away from the work area, and the safety lever helps reduce accidental start-up risk during handling, accessory changes, and repositioning.

Features:

• Powerful 1.2 hp / 900 W governed motor supports controlled grinding, deburring, and contouring in production and maintenance work.
• 1/4" collet capacity fits widely used industrial die grinder accessories with compatible shank size and speed rating.
• Rear exhaust helps direct discharged air away from the workpiece and operator position.
• Streamlined safety lever helps reduce unintentional tool start-up during handling.
• Steel housing with insulating composite over-housing improves grip feel while protecting the tool body in shop use.
• Manufacturer-listed maintenance interval of up to 2,000 hours supports planned service schedules in high-use environments.

IMPORTANT: The maximum operating speed of any abrasive accessory must equal or exceed the maximum speed of the tool. Never mount saw blades or non-reinforced grinding wheels. Always wear appropriate eye, face, and body protection.

Applications:

• Metal fabrication: removing burrs, blending edges, and cleaning weld-adjacent surfaces on steel and non-ferrous components.
• Industrial maintenance and MRO: fitting parts, smoothing machined edges, and preparing small areas before repair or assembly.
• Vehicle service and fleet repair: cleaning gasket surfaces, removing corrosion in tight areas, and dressing small metal imperfections.
• Tool room and machining support: contouring castings, finishing profiles, and refining part details after machining operations.
• Oil, gas, and petrochemical maintenance shops: pneumatic grinding and deburring tasks where the tool specifications match site requirements.

FAQs:

• Q: What accessories fit the CP3119-060?
  A: This model uses a 1/4" collet, so accessories must have a compatible 1/4" shank and a maximum operating speed rating that equals or exceeds the grinder speed. Common compatible accessory types include carbide burrs, mounted points, and abrasive stones made for straight die grinders.
• Q: Is this a high-speed pencil grinder?
  A: No. The CP3119-060 is a straight die grinder, not a pencil grinder. It uses a larger 1/4" collet and a 1.2 hp motor for heavier deburring and contouring work than typical fine-detail pencil grinders.
• Q: What air setup should be used with this grinder?
  A: Match the grinder to an air system that can support the listed air consumption and 3/8" air inlet connection. A properly sized hose, clean regulated air, and lubrication are important for maintaining speed and reducing premature wear.
• Q: What does a governed motor do?
  A: A governed motor helps control speed under load, so the tool can stay more consistent when the accessory is cutting into metal. This is useful for deburring and contouring work where stalling or excessive speed drop can affect finish quality.
• Q: Can this tool be used with cut-off wheels?
  A: Use only accessories that are rated for straight die grinders, match the collet size, and meet the required speed rating. Do not mount saw blades or non-reinforced grinding wheels on this tool.
