Chicago Pneumatic Straight Die Grinder | CP3109-15 | 15000 RPM | 1/4" Collet

Built for controlled straight-line deburring, grinding, contouring, and cleaning, the Chicago Pneumatic CP3109-15 straight die grinder delivers 15,000 RPM free speed for use with compatible carbide burrs, mounted points, abrasive wheels, and flap wheels. Its 1/4" / 6.4 mm collet capacity supports common shank-mounted accessories, while the 0.8 HP / 600 W pneumatic motor provides productive power for fabrication, foundry, maintenance, and toolroom work. Compared with the CP3109-15ES extended-shaft model, this standard-body version keeps the same 15,000 RPM speed in a shorter tool for accessible work areas, benches, fixtures, and open part edges.

The CP3109-15 is part of Chicago Pneumatic's high-durability CP3109 straight die grinder range, with manufacturer-listed maintenance intervals up to 2,000 hours under specified operating conditions. Its 8.74" / 222 mm length and 1.98 lb / 0.9 kg weight make it easier to control than longer reach models when the work surface is directly accessible. A streamlined safety lever helps reduce accidental start risk, while the steel housing with insulating composite over-housing supports repeated grinding, edge breaking, burr removal, and finishing tasks in compressed-air work environments.

FAQs:

• Q: What is the CP3109-15 best used for?
  A: The CP3109-15 is used for straight-line deburring, grinding, contouring, cleaning, and finishing with compatible shank-mounted accessories. Its standard body is best when the work area is open and does not require an extended-shaft grinder.
• Q: How is the CP3109-15 different from the CP3109-15ES?
  A: Both models run at 15,000 RPM and use 0.8 HP / 600 W pneumatic power, but the CP3109-15 has the shorter standard body at 8.74" / 222 mm. The CP3109-15ES is the extended-shaft version for deeper pockets, recessed surfaces, and hard-to-reach grinding points.
• Q: What collet size does this grinder use?
  A: The CP3109-15 is listed with a 1/4" / 6.4 mm collet capacity. Match the accessory shank to the installed collet before use, and confirm accessory speed rating before mounting any burr, mounted point, or abrasive wheel.
• Q: What air supply does the CP3109-15 require?
  A: Chicago Pneumatic lists 31 CFM / 15 l/s air consumption at load and a 3/8" air inlet. Use clean, regulated, lubricated air and confirm the correct fitting/thread standard for your shop air system before installation.
• 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 15,000 RPM free speed. Always confirm shank size, accessory type, workpiece material, and the accessory manufacturer's safety rating before use.
