Chicago Pneumatic Random Orbital Sander | CP5518-50 | 10000 RPM | 5" PSA Pad | 3/4" Orbit

Built for sanding, finishing, and pre-polishing work on prepared surfaces, the Chicago Pneumatic CP5518-50 pneumatic random orbital sander combines a 10,000 RPM free speed with a 0.5 hp / 375 W motor to keep the abrasive moving quickly across paint, primer, filler, and fabricated parts. Its 5" / 127 mm PSA circular pad uses pressure-sensitive adhesive discs, giving the abrasive a secure hold during surface preparation and finishing passes.

The manufacturer data for SKU 6151701980 lists a 9/16" / 14 mm orbit, which creates a more aggressive random orbital motion than smaller finishing orbits and helps speed up surface preparation before polishing or coating. This non-vacuum CP55 Series model is suited to shops that use separate dust control, booth extraction, or cleanup processes rather than tool-integrated self-vacuum or central-vacuum collection.

Features:

• 0.5 hp / 375 W oil-free pneumatic motor supports sanding, finishing, and pre-polishing work while helping protect the sanding process from exhaust-related oil contamination.
• 10,000 RPM free speed provides fast pad motion for paint preparation, surface refinement, and polishing-related finishing steps.
• 5" / 127 mm circular PSA pad holds adhesive-backed abrasive discs securely during repeated sanding passes.
• 9/16" / 14 mm orbit provides aggressive random orbital action for faster surface preparation compared with smaller-orbit finishing tools.
• Standard body configuration keeps the tool compact for panel work, spot repair, and general surface preparation.
• Non-vacuum configuration works well where separate dust collection, booth extraction, or manual cleanup processes are already in place.
• Integrated motor silencer helps reduce tool noise in body shop, repair, and production environments.
• Safety lever starting system helps reduce accidental activation while positioning the tool or changing abrasive discs.

Applications:

• Autobody refinishing: Preparing repair panels, smoothing primer, and refining filler before paint, clearcoat, or polishing steps.
• Paint and coating preparation: Sanding painted, primed, and coated surfaces where a 5" circular pad gives controlled contact.
• Metal fabrication: Blending surface marks, preparing fabricated parts, and refining workpieces before finishing or coating.
• Industrial maintenance and MRO: Cleaning up covers, housings, panels, and repair surfaces during equipment refurbishment.
• Garage and workshop projects: General sanding and pre-polishing on compatible materials when paired with PSA abrasive discs and a compressor sized for the tool’s air demand.

FAQs:

• Q: What does PSA pad mean?
  A: PSA stands for pressure-sensitive adhesive. This model uses adhesive-backed sanding discs that stick directly to the pad, rather than hook & loop discs.
• Q: What does non-vacuum mean on the CP5518-50?
  A: Non-vacuum means the tool does not include built-in self-vacuum or central-vacuum dust extraction. Use separate dust control, shop ventilation, or cleanup procedures based on the material being sanded.
• Q: Is the CP5518-50 mainly for sanding or polishing?
  A: Chicago Pneumatic lists this model in the orbital sanders and polishing machines family. It can be used for sanding, finishing, and pre-polishing tasks when matched with the correct PSA abrasive or finishing media.
• Q: What air supply does this sander require?
  A: The CP5518-50 is rated for 90 PSI / 6.3 bar and uses 23 CFM / 11 l/s at load. Use a properly sized 3/8" / 10 mm air hose and confirm the compressor can maintain airflow during continuous sanding work.
• Q: Can hook & loop abrasive discs be used on this model?
  A: No. This version is specified with a PSA pad, so use compatible 5" adhesive-backed abrasive discs unless the pad has been changed to a manufacturer-approved alternate pad.
