Chicago Pneumatic Extended Low-Speed Air Tire Buffer | CP873C-HDES | 3500 RPM | 7/16" Hex Quick-Change Chuck

Built for tire retreading, repair prep, and controlled buffing work, the Chicago Pneumatic CP873C-HDES Extended Low-Speed Air Tire Buffer gives tire shops and retread operations a longer-reach version of the CP873C-HD platform. Its 3,500 RPM free speed supports low-speed buffing control when preparing rubber surfaces, while the 7/16" hex quick-change slip chuck helps speed up buffing wheel changes without slowing down the repair workflow. With 0.67 hp of power and an extended 11.85" overall length, this air tire buffer is suited for reaching deeper tire sections while keeping the tool manageable at 2.56 lb.

The CP873C-HDES combines an aluminum body with a composite over-sleeve for a lighter hand feel during repeated tire service tasks. A rear exhaust directs spent air away from the work area, while the safety lever and reinforced lock-off design help reduce accidental starts during handling. The air swivel inlet adds hose movement flexibility, which is especially useful when moving around large tires, repair stands, and retread stations.

FAQs:

• Q: What is the CP873C-HDES used for?
  A: It is used for low-speed tire buffing during tire repair and retreading preparation. The tool helps roughen and prepare rubber surfaces before patching, bonding, or other tire service steps.
• Q: What makes the CP873C-HDES different from the standard CP873C-HD?
  A: The CP873C-HDES is the extended version, giving the operator more reach than the standard CP873C-HD. That added length is useful when working on larger tires or areas where a shorter buffer is harder to position.
• Q: What does a 7/16" hex quick-change slip chuck do?
  A: The 7/16" hex chuck accepts compatible buffing wheel accessories and allows quicker accessory changes than a slower threaded setup. Always verify that the buffing accessory matches the chuck size and speed rating before use.
• Q: What air line size should be used with this tire buffer?
  A: Chicago Pneumatic specifies a minimum hose diameter of 3/8" or 10 mm for a 16 ft / 5 m hose length. Using an undersized hose can restrict airflow and reduce tool performance.
• Q: Is this a high-speed grinder?
  A: No. This is a low-speed air tire buffer running at 3,500 RPM, intended for tire buffing and retread preparation tasks. It should not be substituted for a general-purpose die grinder or cutting tool.
