Chicago Pneumatic Random Orbital Sander | CP5518-50H | 10000 RPM | 5" Hook & Loop Pad | 3/4" Orbit

Built for industrial sanding, finishing, and pre-polishing work, the Chicago Pneumatic CP5518-50H pneumatic random orbital sander / polisher combines a 10,000 RPM free speed with a 0.5 hp / 375 W oil-free motor to help technicians refine painted, primed, and prepared surfaces without oil contamination from the tool exhaust. Its 5" / 125 mm hook & loop circular pad supports quick abrasive changes, while the long-body configuration gives added reach and two-hand control on panels, edges, and larger work areas.

This non-vacuum CP55 Series model is suited to shops that use separate dust control methods or where open sanding and polishing work does not require tool-integrated extraction. The manufacturer-listed 9/16" / 14 mm orbit gives the pad an aggressive random orbital motion for fast surface preparation and pre-polishing steps, making the tool useful for autobody repair, fabrication finishing, vehicle service, and industrial maintenance environments.

Features:

• 0.5 hp / 375 W oil-free pneumatic motor supports sanding, finishing, and pre-polishing work while helping protect surfaces from exhaust-related oil contamination.
• 10,000 RPM free speed provides fast pad motion for surface refinement, coating preparation, and polishing-related finishing steps.
• 5" / 125 mm circular hook & loop pad allows quick abrasive changes during staged sanding and finishing processes.
• 9/16" / 14 mm orbit provides aggressive random orbital action for faster surface preparation compared with smaller-orbit finishing tools.
• Long-body configuration gives added reach and control for technicians working across panels, curves, and larger surface areas.
• Non-vacuum configuration works well where separate dust collection, booth extraction, or cleanup processes are already in place.
• Integrated motor silencer helps reduce operating noise in body shop, repair, and production environments.
• Safety lever starting system helps reduce accidental activation while positioning the tool or changing abrasives.

Applications:

• Autobody refinishing: Preparing repair panels, smoothing primer, and refining surfaces before polishing or coating steps.
• Paint and surface preparation: Sanding painted, primed, and coated surfaces where a 5" circular pad provides maneuverability and controlled contact.
• Metal fabrication: Blending surface marks, preparing fabricated parts, and refining workpieces before finishing or coating.
• Industrial maintenance and MRO: Cleaning up panels, covers, housings, and repair surfaces during equipment refurbishment.
• Vehicle service and garage work: General sanding and pre-polishing tasks when paired with compatible hook & loop abrasives and a compressor sized for the tool's air demand.

FAQs:

• Q: Is the CP5518-50H a sander or a polisher?
  A: Chicago Pneumatic lists this model in the orbital sanders and polishing machines family and describes it as a 5" pad polisher. It can be used for sanding, finishing, and pre-polishing tasks when matched with the correct hook & loop abrasive or finishing media.
• Q: What does non-vacuum mean on this model?
  A: Non-vacuum means the tool does not have built-in self-vacuum or central-vacuum dust extraction. Use separate dust control, shop ventilation, or cleanup procedures appropriate for the material being sanded.
• Q: What abrasive pad style does this tool use?
  A: The CP5518-50H uses a 5" / 125 mm circular hook & loop pad. Use compatible hook & loop abrasive discs; PSA adhesive-backed discs are not the correct attachment style for this pad.
• Q: What air supply does the CP5518-50H require?
  A: The tool is rated for 90 PSI / 6.3 bar and uses 23 CFM / 11 l/s at load. Use a properly sized air hose and confirm the compressor can maintain airflow during continuous sanding or polishing work.
• Q: What does the orbit size affect?
  A: Orbit size is the diameter of the pad's random sanding motion. A larger orbit removes material faster and is useful for surface preparation and pre-polishing, while smaller orbit tools generally leave a finer finish pattern.
