Chicago Pneumatic Random Orbital Sander | CP5510-50H | 10000 RPM | 5" Hook & Loop Pad | 3/8" Orbit

Built for fast surface preparation, sanding, and pre-polishing work, the Chicago Pneumatic CP5510-50H pneumatic random orbital sander delivers a 10,000 RPM free speed with a 0.5 hp / 375 W motor for consistent abrasive motion across repair panels, primed surfaces, fabricated parts, and finishing areas. Its 5" / 127 mm hook & loop circular pad gives technicians a versatile sanding footprint for common autobody, maintenance, and workshop applications while allowing quick abrasive disc changes between grit steps.

The 3/8" / 10 mm orbit creates a more aggressive random orbital pattern than fine-finish orbit sizes, helping remove coatings, primer, filler, and surface imperfections efficiently before final finishing. This non-vacuum CP55 Series model is suited to shops that already use booth ventilation, separate dust extraction, or manual cleanup procedures. The handle-equipped body gives added reach and control during longer sanding passes on panels, edges, and larger work areas.

Features:

• 0.5 hp / 375 W pneumatic motor supports sanding, finishing, and pre-polishing work on prepared surfaces.
• 10,000 RPM free speed keeps the abrasive moving quickly for coating prep, surface refinement, and material removal.
• 5" / 127 mm circular hook & loop pad allows fast abrasive disc changes during staged sanding and finishing work.
• 3/8" / 10 mm orbit provides an aggressive sanding pattern for faster preparation compared with smaller-orbit finishing tools.
• Non-vacuum configuration keeps the setup straightforward for work areas using separate dust control or booth extraction.
• Handle-equipped body gives added reach and control when sanding panels, edges, and extended work areas.
• 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 abrasive discs.

Applications:

• Autobody repair and refinishing: Sanding repair panels, primer, filler, and blend areas before paint or clearcoat work.
• Paint and coating preparation: Removing surface imperfections and preparing painted, primed, or coated surfaces for the next finishing step.
• Metal fabrication: Blending surface marks, smoothing fabricated parts, and preparing components before coating or finishing.
• Industrial maintenance and MRO: Cleaning up panels, guards, covers, housings, and repair areas during equipment refurbishment.
• Workshop and garage use: General sanding on compatible materials when paired with hook & loop abrasive discs and a compressor sized for the tool’s airflow demand.

FAQs:

• Q: What abrasive discs fit the CP5510-50H?
  A: This model uses 5" / 127 mm circular hook & loop abrasive discs. PSA adhesive-backed discs are not the correct attachment style for the supplied hook & loop pad.
• Q: What does the 3/8" orbit do?
  A: Orbit diameter is the size of the pad’s random sanding motion. A 3/8" / 10 mm orbit removes material faster than smaller fine-finish orbits, making it useful for primer sanding, coating removal, and surface preparation.
• Q: What does non-vacuum mean on this sander?
  A: Non-vacuum means the tool does not include self-vacuum or central-vacuum dust extraction. Use separate dust collection, booth ventilation, or cleanup procedures appropriate for the material being sanded.
• Q: Is the CP5510-50H a good choice for paint preparation?
  A: Yes, it is well suited for paint prep, primer sanding, filler smoothing, and pre-polishing work when used with the correct abrasive grit. The 5" pad balances coverage and control for common panel work.
• Q: What air supply does this random orbital sander need?
  A: The CP5510-50H is rated for 90 PSI / 6.3 bar and uses 23 CFM / 11 l/s at load. Use a 3/8" / 10 mm air hose and confirm the compressor can maintain airflow during continuous sanding.
