Chicago Pneumatic Angle Die Grinder | CP3550-180 | 18000 RPM | 1/4" (6 mm) Collet

Designed for controlled grinding, deburring, blending, and finishing applications, the Chicago Pneumatic CP3550-180 Angle Die Grinder delivers 18,000 RPM free speed for use with compatible mounted points, carbide burrs, and abrasive accessories. Its 0.9 HP / 670 W pneumatic motor provides a balance of power and compact handling, while the 1/4" (6 mm) collet accepts common shank-mounted accessories for metal preparation, weld cleanup, and detail grinding tasks. The compact angled head design helps operators reach work areas where a straight die grinder may not provide the desired access or control.

The CP3550-180 is part of Chicago Pneumatic’s CP3550 Series of professional die grinders, designed for body shop, MRO, fabrication, and general industrial applications. The lightweight aluminum housing, insulated composite over-housing, and angled configuration help provide operator control during repeated grinding and finishing work. A safety lever starting system helps reduce accidental activation, while the rear exhaust directs spent air away from the immediate work area.

FAQs:

• Q: What accessories can be used with the CP3550-180?
  A: The CP3550-180 uses a 1/4" / 6 mm collet for compatible mounted points, carbide burrs, and other shank-mounted grinding accessories. Always confirm accessory shank size and maximum operating speed before use.
• Q: What is the advantage of an angle die grinder compared with a straight die grinder?
  A: An angle die grinder positions the accessory at an angle to the tool body, which can improve access and control when working around corners, edges, and recessed areas.
• Q: What air supply does this die grinder require?
  A: Chicago Pneumatic lists 25 CFM / 12 l/s air consumption at load and 28 CFM / 13.2 l/s at free speed. Use clean, regulated air at 90 PSI / 6.3 bar through the recommended 0.38" / 10 mm minimum hose diameter.
• Q: Can this tool be used with any 1/4" mounted accessory?
  A: No. Accessories must match the collet size and must have a maximum operating speed equal to or higher than the grinder’s 18,000 RPM free speed. Always follow the accessory manufacturer’s safety requirements.
• Q: Does this model include a spindle lock?
  A: The supplied product data does not list a spindle lock feature for the CP3550-180. Use the correct accessory-change procedure and compatible tooling for this model.
