Chicago Pneumatic Orbital Sander | CP5506-R8HSV | 8000 RPM | 4.5"x8.5" Hook & Loop Pad | 3/16" Orbit

Built for larger flat-surface sanding, paint preparation, and pre-polishing work, the Chicago Pneumatic CP5506-R8HSV pneumatic orbital sander combines an 8,000 RPM free speed with a 0.5 hp / 375 W motor to keep abrasive sheets moving consistently across body panels, fabricated parts, and refinishing surfaces. Its larger 8.5" x 4.5" hook & loop rectangular pad gives technicians more contact area than smaller rectangular-pad models, helping cover broad surfaces efficiently while maintaining control.

The 3/16" / 5 mm orbit provides a balanced sanding action for surface prep and finishing- fine enough to help manage scratch pattern quality, while still capable of removing coatings, primer, filler, and surface imperfections. The self-vacuum configuration helps draw sanding dust away from the work surface when used with compatible dust collection components, making this CP55 Series sander a practical choice for autobody, metalworking, maintenance, and production sanding environments.

Features:

• 0.5 hp / 375 W pneumatic motor supports consistent sanding output for surface preparation, finishing, and pre-polishing work.
• 8.5" x 4.5" rectangular hook & loop pad provides broad surface coverage and quick abrasive sheet changes.
• 3/16" orbit diameter delivers a controlled sanding pattern for coating removal, primer prep, and finish refinement.
• Self-vacuum configuration helps remove sanding dust from the work area when paired with compatible dust extraction components.
• Integrated motor silencer helps reduce tool noise in busy shop and production environments.
• Lubrication-free motor helps protect sanding and finishing work from oil contamination in the exhaust stream.
• Safety lever starting system helps prevent accidental activation while positioning the tool or changing abrasives.
• Rated for 2,000 operating hours with low maintenance supports dependable service in regular production and repair use.

Applications:

• Autobody refinishing: Sanding larger body panels, primer, filler, and paint-prep surfaces before finishing or blending.
• Metal fabrication: Preparing sheet metal, formed panels, welded assemblies, and coated surfaces for finishing steps.
• Industrial maintenance and MRO: Removing surface marks, oxidation, old coatings, and repair-area imperfections during equipment refurbishment.
• Vehicle service and fleet shops: Smoothing repair panels and maintenance surfaces where a larger rectangular pad helps cover more area per pass.
• Workshop and garage use: General sanding on compatible materials when paired with the correct abrasive grit and a compressor sized for the tool’s air demand.

FAQs:

• Q: What is the main advantage of the CP5506-R8HSV over the smaller CP5506-R6HSV?
  A: The CP5506-R8HSV uses a larger 8.5" x 4.5" / 215 x 113 mm rectangular pad, giving it more coverage on broad surfaces. It is better suited to larger panels and longer sanding passes, while smaller-pad models may feel more maneuverable on tighter areas.
• Q: What does the 3/16" orbit mean?
  A: Orbit diameter is the size of the sanding motion made by the pad. A 3/16" / 5 mm orbit is a balanced choice for surface preparation because it removes material at a useful rate while helping maintain a more controlled finish pattern than more aggressive, larger-orbit tools.
• Q: What does self-vacuum mean on this sander?
  A: Self-vacuum means the tool is configured to help pull sanding dust away from the surface without requiring a central vacuum system. For best results, use compatible hook & loop abrasives and dust collection components that match the tool's vacuum setup.
• Q: What air supply does the CP5506-R8HSV 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 line and confirm the compressor can maintain enough continuous airflow for extended sanding sessions.
• Q: Can this sander be used for paint prep and primer sanding?
  A: Yes, this model is suited to paint preparation, primer sanding, filler smoothing, and pre-polishing work when used with the correct abrasive grit and dust collection setup for the material.
