Chicago Pneumatic Straight Die Grinder | CP3119-010 | 1000 RPM | 1/4" Collet

Built for slow-speed grinding, finishing, and controlled surface work, the Chicago Pneumatic CP3119-010 Straight Die Grinder gives fabrication shops, maintenance teams, and repair benches a powerful pneumatic tool for 1/4" shank accessories. Its 1,000 RPM free speed is the lowest-speed option in this CP3119 group, making it useful when the user needs deliberate control rather than high spindle speed. The 1/4" collet accepts compatible carbide burrs, mounted points, abrasive stones, and other straight die grinder accessories when the shank size and accessory speed rating match the tool.

The CP3119-010 uses a 1.2 hp / 900 W governed motor, which helps the tool hold working speed as load changes during deburring, contouring, and material cleanup. The straight-body layout supports two-hand control on bench work and in-place maintenance tasks, while the rear exhaust helps direct discharged air away from the immediate work area. For shops that need a slower pneumatic grinder for controlled contact with the workpiece, this model fills a different role than higher-speed die grinders in the same series.

Type: Straight Die Grinder | Series: CP3119 | Model: CP3119-010 | SKU: 6151701680 | Free Speed: 1,000 RPM | Power: 1.2 hp / 900 W | Collet Capacity: 1/4" (6.4 mm) | Air Consumption at Load: 36 CFM / 17 l/s | Net Weight: 3.09 lb / 1.4 kg | Length: 8.74" / 222 mm | Vibration: 3.8 m/s² | Sound Pressure: 81 dB(A) | Sound Power: 92 dB(A) | Air Inlet: 3/8"

Features:

• Powerful 1.2 hp / 900 W governed motor supports controlled grinding and finishing under changing load conditions.
• 1,000 RPM free speed provides slower spindle control for applications where high-speed stock removal is not required.
• 1/4" collet capacity works with compatible straight die grinder accessories, including mounted points, burrs, and abrasive tools rated for the application.
• Straight housing allows direct alignment with the workpiece for bench finishing, deburring, and in-place maintenance work.
• Rear exhaust helps move discharged air away from the work surface and accessory contact point.
• Safety lever starting system helps reduce accidental activation during handling, repositioning, or accessory setup.
• Aluminum body with composite over-sleeve provides a practical grip surface while helping protect the tool housing in shop use.

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: controlled deburring, edge easing, and surface cleanup where slower accessory speed helps maintain contact control.
• Industrial maintenance and MRO: fitting worn components, cleaning small areas, and preparing metal surfaces before repair or assembly.
• Machining and tool room support: removing burrs from machined parts, refining profiles, and finishing cast or milled surfaces.
• Vehicle and fleet repair: cleaning gasket surfaces, removing localized corrosion, and dressing small imperfections on metal parts.
• General shop finishing: low-speed pneumatic grinding tasks where a straight-body tool and 1/4" accessory shank are required.

FAQs:

• Q: Why would I choose the CP3119-010 instead of a faster die grinder?
  A: The CP3119-010 runs at 1,000 RPM, so it is suited to slower, more controlled contact with the workpiece. Choose it when the accessory type, material, or finish requirement calls for lower spindle speed instead of fast stock removal.
• Q: What accessories fit this grinder?
  A: This model uses a 1/4" collet, so accessories must have a compatible 1/4" shank. The accessory must also be rated for the tool speed and intended use before installation.
• Q: Is this the same type of tool as a pencil grinder?
  A: No. The CP3119-010 is a straight die grinder with a 1/4" collet and a 1.2 hp motor. Pencil grinders are typically smaller, higher-speed tools used for fine-detail finishing with smaller collets.
• Q: What does the governed motor do?
  A: A governed motor helps manage tool speed as load changes. That helps the grinder stay more consistent when the accessory contacts the workpiece during deburring, shaping, or finishing work.
• Q: What air supply is required?
  A: The catalog lists air consumption at load as 36 CFM / 17 l/s with a 3/8" air inlet. Use a properly regulated air system and hose setup that can support the tool during sustained operation.
