Chicago Pneumatic Angle Die Grinder | CP3109-13ACES | 13000 RPM | 1/4" (6 mm) Collet

Built for angle-access deburring, grinding, contouring, and cleaning work, the Chicago Pneumatic CP3109-13ACES Angle Die Grinder delivers 13,000 RPM free speed for controlled use with carbide burrs, mounted points, abrasive wheels, and flap wheels. Its 0.8 HP / 600 W governed pneumatic motor helps maintain working speed under load, which matters when the tool is pressed into weld edges, casting flash, drilled holes, or machined contours. The angle-head layout helps reach surfaces that are awkward for a straight die grinder, while the extended housing improves access into recessed areas, fixtures, and assemblies where standard-length angle grinders may feel cramped.

The CP3109-13ACES is part of Chicago Pneumatic's CP3109 Angle Die Grinder range and is built for intensive daily use in metal fabrication, foundry cleanup, maintenance, and production environments. A safety lever starting system helps reduce accidental start risk, while the aluminum body with composite over-sleeve gives the operator a more manageable grip surface during repeated grinding tasks. The tool is listed with 3.09 lb / 1.4 kg weight and 11.3" / 287 mm length, giving it more reach than shorter angle die grinders without moving into a full straight extended-shaft configuration.

Features:

• 13,000 RPM free speed supports controlled grinding, contouring, deburring, and cleaning with compatible mounted abrasive accessories.
• 0.8 HP / 600 W governed motor helps maintain tool speed during heavier contact with burrs, mounted points, abrasive wheels, and flap wheels.
• Angle-head configuration improves access to edges, corners, weld details, castings, and surfaces that are difficult to approach with a straight grinder.
• Extended housing helps reach farther into recessed work areas, assemblies, fixtures, and fabricated structures.
• Very durable bevel gear supports intensive angle-grinding use where the head is repeatedly loaded during material removal.
• Streamlined safety lever helps reduce accidental start risk during tool handling and positioning.
• Aluminum body with composite over-sleeve provides a durable housing with an insulated, more manageable grip surface.
• Highest durability in demanding applications, up to 2,000 hours maintenance intervals.

Applications:

• Metal fabrication: deburring holes, cleaning flame-cut edges, blending welds, and contouring fabricated steel or aluminum parts.
• Foundry and casting cleanup: removing flash, cleaning parting lines, and reaching into casting contours where an angle-head grinder improves access.
• Industrial maintenance and MRO: grinding repair parts, cleaning brackets, smoothing machine components, and preparing surfaces for fit-up.
• Machining and toolroom work: edge breaking, detail finishing, and light contour correction on fixtures, dies, molds, and machined components.
• Vehicle and equipment repair: working around brackets, frames, panels, and fabricated repair parts in compressed-air service shops.

FAQs:

• Q: What is the CP3109-13ACES best used for?
  A: The CP3109-13ACES is used for grinding, contouring, deburring, and cleaning with compatible carbide burrs, mounted points, abrasive wheels, and flap wheels. Its angle-head layout helps when the work surface is hard to approach with a straight die grinder.
• Q: What does the "ES" configuration mean on this model?
  A: In this CP3109 model, the ES version is listed with an extended housing. That added length helps the operator reach farther into recessed work areas, fixtures, castings, and welded assemblies.
• Q: What collet size should I use with this grinder?
  A: The supplied title lists a 15/64" / 6.0 mm collet, while Chicago Pneumatic product data also describes the model as a 1/4" / 6 mm pneumatic angle die grinder. Confirm the installed collet before selecting burrs, mounted points, or replacement collets.
• Q: What air supply does the CP3109-13ACES require?
  A: Chicago Pneumatic lists 21 CFM / 10 l/s air consumption at load. Use an air system that can maintain 90 PSI / 6.3 bar at the tool through a minimum 0.38" / 10 mm hose.
• Q: Can this grinder use any abrasive wheel or flap wheel?
  A: No. The accessory must match the tool configuration, collet or mounting requirements, and material being worked. Its maximum operating speed must be equal to or greater than the grinder's 13,000 RPM free speed.
