Chicago Pneumatic Straight Die Grinder | CP3109-24RT | 24000 RPM | 1/4" Collet

Built for high-speed straight-line deburring, grinding, contouring, and cleaning, the Chicago Pneumatic CP3109-24RT straight die grinder delivers 24,000 RPM free speed for productive work 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 governed pneumatic motor helps maintain abrasive speed when the accessory is loaded against burrs, weld details, casting flash, or machined edges. This model is suited for users who need faster abrasive action than 15,000 or 19,000 RPM grinders while retaining the straight-body control of the CP3109 range.

The CP3109-24RT uses the same 8.74" / 222 mm standard straight body length as the CP3109-24, with a higher listed weight of 2.64 lb / 1.2 kg. The straight configuration gives direct access to open work areas, benches, fixtures, and accessible part edges, while the steel housing with insulating composite over-housing provides a manageable grip surface during repeated grinding and finishing work. Its safety lever starting system helps reduce accidental start risk, and the CP3109 range is listed for high durability with maintenance intervals up to 2,000 hours under specified operating conditions.

FAQs:

• Q: What is the CP3109-24RT best used for?
  A: The CP3109-24RT is used for high-speed straight-line deburring, grinding, contouring, cleaning, and finishing with compatible shank-mounted accessories. Its 24,000 RPM speed is useful for smaller burrs and mounted points where fast abrasive action is needed.
• Q: How is the CP3109-24RT different from the CP3109-24?
  A: Both models run at 24,000 RPM and use a 1/4" / 6.4 mm collet, but the CP3109-24RT is listed under a separate SKU with a higher catalog weight and higher listed vibration and sound values. Confirm the RT configuration with Chicago Pneumatic or IntlAirTool if comparing it directly to the standard CP3109-24.
• Q: What collet size does this grinder use?
  A: SKU 6151702900 is listed with a 1/4" / 6.4 mm collet capacity. Match the accessory shank to the installed collet before use, and verify the accessory's maximum operating speed before mounting it.
• Q: What air supply does the CP3109-24RT require?
  A: Chicago Pneumatic lists 31 CFM / 15 l/s air consumption at load and a 3/8" air inlet. The CP3109 catalog table lists all models for use with a 3/8" / 10 mm hose at 90 PSI / 6.3 bar.
• Q: Can this grinder use any carbide burr, mounted point, or abrasive 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 24,000 RPM free speed. Always confirm shank size, accessory type, workpiece material, and the accessory manufacturer's safety rating before use.
