Chicago Pneumatic Random Orbital Sander | CP5510-44H | 10000 RPM | 4.4" Hook & Loop Pad | 3/8" Orbit

Built for controlled circular-pad sanding, finishing, and pre-polishing work, the Chicago Pneumatic CP5510-44H pneumatic random orbital sander delivers a 10,000 RPM free speed with a 0.5 hp / 375 W oil-free motor to keep abrasive motion fast and consistent across prepared surfaces. Its compact 4.4" / 110 mm hook & loop circular pad gives technicians a smaller contact area for spot repair, panel edges, contour work, and tight sanding zones where larger 5" or 6" pads may be harder to control.

The manufacturer data for SKU 6151700770 lists a 5/16" / 8 mm orbit, which provides a balanced random orbital sanding pattern for surface preparation, coating removal, primer work, and finish refinement. This non-vacuum CP55 Series model is suited to shops that use separate dust control, booth ventilation, or cleanup systems rather than tool-integrated vacuum collection. The oil-free motor helps protect sanding and finishing processes from exhaust-related oil contamination.

Features:

• 0.5 hp / 375 W oil-free pneumatic motor supports sanding, finishing, and pre-polishing while helping protect work surfaces from exhaust-related oil contamination.
• 10,000 RPM free speed keeps the abrasive moving quickly for paint preparation, surface refinement, and light material removal.
• 4.4" / 110 mm circular hook & loop pad allows fast abrasive changes and controlled contact on smaller work areas.
• 5/16" / 8 mm orbit provides a balanced sanding pattern for coating removal, primer sanding, and finish preparation.
• Non-vacuum configuration keeps the tool setup simple for work areas that use separate dust extraction, booth ventilation, or manual cleanup.
• 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.
• Listed 2000 operating hours with low maintenance supports regular use in sanding and surface preparation workflows.

Applications:

• Autobody repair and refinishing: Sanding spot repairs, panel edges, primer, filler, and blend areas before paint or polishing steps.
• Paint and coating preparation: Refining painted, primed, and coated surfaces where a smaller circular pad improves control.
• Metal fabrication: Blending surface marks, smoothing fabricated parts, and preparing smaller components before finishing or coating.
• Industrial maintenance and MRO: Cleaning up covers, housings, equipment panels, and repair surfaces during refurbishment work.
• Workshop and garage use: General sanding on compatible materials when paired with hook & loop abrasives and a compressor sized for the tool's airflow demand.

FAQs:

• Q: What abrasive discs fit the CP5510-44H?
  A: This model uses 4.4" / 110 mm circular hook & loop abrasive discs. PSA adhesive-backed discs are not the correct attachment style for the hook & loop pad.
• Q: What is the advantage of the smaller 4.4" pad?
  A: The 4.4" pad gives more control on spot repairs, edges, contours, and smaller parts. Larger 5" or 6" sanders cover more area per pass, but this size is useful where precision and maneuverability matter.
• 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 control, shop ventilation, or cleanup procedures appropriate for the material being sanded.
• Q: Is the CP5510-44H suitable for finish preparation?
  A: Yes. The listed 5/16" / 8 mm orbit gives a balanced sanding action for surface preparation, primer sanding, and coating refinement before finishing steps.
• Q: What air supply does this random orbital sander need?
  A: The CP5510-44H is rated for 90 PSI / 6.3 bar and uses 23 CFM / 11 l/s at load. Use at least a 0.31" / 8 mm air hose and confirm the compressor can maintain airflow during continuous sanding.
