Built for tire repair, patch preparation, and buffing accessory work, the Chicago Pneumatic CP871C High-Speed Air Tire Buffer gives tire shops and service bays a compact pneumatic tool for cleaning and preparing rubber surfaces before repair. Its 22,000 RPM free speed provides fast surface preparation where controlled material removal matters, while the 3/8" keyed chuck accepts compatible buffing accessories up to 10 mm for common tire repair tasks. The 0.47 HP / 350 W output, rear exhaust, and straight-handle configuration make the CP871C well suited for technicians who need a light, maneuverable tire buffer rather than a larger grinder or sander.
The CP871C uses a composite over-sleeve and aluminum body to reduce cold transfer from the air motor during use, and its lock-off safety lever helps prevent accidental start-up. Speed control allows the technician to adjust the tool response for different buffing accessories and tire repair steps, while the 1/4" NPT air inlet and 3/8" minimum hose size match common shop air setups.

FAQs:
- Q: What is the CP871C used for?
A: The CP871C is a high-speed pneumatic tire buffer used to prepare tire surfaces for patching and repair. It is commonly used with compatible buffing accessories to clean, texture, or prepare the repair area. - Q: What does 22,000 RPM mean for tire repair work?
A: The 22,000 RPM free speed refers to the tool speed without load. In practical use, it gives technicians fast surface preparation for rubber repair areas when paired with the correct buffing accessory. - Q: What air hose size should be used with this tire buffer?
A: Chicago Pneumatic lists a 3/8" / 10 mm minimum hose diameter for a 16 ft / 5 m hose length. Using an undersized hose can restrict airflow and reduce tool performance. - Q: Is the CP871C the high-speed or low-speed version?
A: The CP871C is the high-speed tire buffer in the CP871C / CP873C light-duty tire buffer range. The CP873C is the lower-speed version used for different tire repair operations. - Q: Does this tool require lubrication?
A: Yes. As a pneumatic tool, it should be run with clean, regulated, properly lubricated air according to Chicago Pneumatic operating instructions. A properly sized FRL helps protect the air motor and maintain consistent performance.
