Chicago Pneumatic Random Orbital Sander | CP5303-35 | 12000 RPM | 3.5" PSA Pad | 3/32" Orbit

Built for fine circular-pad sanding, spot repair, and finish preparation, the Chicago Pneumatic CP5303-35 pneumatic random orbital sander delivers a fast 12,000 RPM free speed with a 0.3 hp / 210 W motor for controlled abrasive motion on smaller panels, contours, repair areas, and prepared surfaces. Its 3.5" / 90 mm PSA circular pad uses pressure-sensitive adhesive abrasive discs, giving technicians secure disc attachment for detail sanding and repeated finishing passes.

The 3/32" / 2.4 mm orbit creates a finer random orbital sanding pattern than larger 3/16" or 3/8" orbit models, making this CP53 Series sander useful for finish refinement, light surface preparation, primer smoothing, and pre-polishing work. This non-vacuum configuration is suited to shops that already use separate dust extraction, booth ventilation, or manual cleanup procedures. The compact palm-grip body helps keep the tool manageable on small work areas where larger 5" or 6" sanders may remove too much material or cover too much surface at once.

Features:

• 0.3 hp / 210 W pneumatic motor supports efficient sanding, finishing, and pre-polishing work on smaller prepared surfaces.
• 12,000 RPM free speed keeps the abrasive moving quickly for fine surface preparation and finish refinement.
• 3.5" / 90 mm circular PSA pad provides compact abrasive contact and secure adhesive-backed disc retention.
• 3/32" / 2.4 mm orbit creates a fine sanding pattern for finish preparation, primer smoothing, and light surface correction.
• Non-vacuum configuration works well in shops using separate dust collection, booth ventilation, or manual cleanup procedures.
• Ergonomic palm-shaped soft grip helps improve control during spot sanding, edge work, and detail repair tasks.
• Integrated motor silencer helps reduce operating noise in body shop, repair, and production environments.
• Lubrication-free motor helps reduce oil carryover concerns around paint preparation, sanding, and finishing work.
• Listed 2000 operating hours with low maintenance supports regular use in sanding and surface preparation workflows.

Applications:

• Autobody repair and refinishing: Sanding spot repairs, small panels, primer, filler, and blend areas before paint or polishing steps.
• Fine finish preparation: Refining prepared surfaces where a smaller 3/32" orbit helps limit sanding marks before finishing.
• Paint and coating preparation: Preparing primed, painted, or coated surfaces where a compact PSA pad improves control.
• Metal fabrication: Smoothing smaller fabricated parts, blending surface marks, and preparing components before coating or final finishing.
• Industrial maintenance and MRO: Cleaning up covers, housings, guards, repair patches, and smaller equipment surfaces during refurbishment.
• Workshop and garage use: Detail sanding on compatible materials when paired with PSA abrasive discs and a compressor sized for the tool's airflow demand.

FAQs:

• Q: What abrasive discs fit the CP5303-35?
  A: This model uses 3.5" / 90 mm circular PSA abrasive discs. PSA stands for pressure-sensitive adhesive, meaning the abrasive disc sticks directly to the pad rather than attaching with hook & loop backing.
• Q: What is the advantage of the 3/32" orbit?
  A: A 3/32" / 2.4 mm orbit produces a finer sanding pattern than larger-orbit sanders. It is useful for finish preparation, primer smoothing, and light surface correction where aggressive material removal is not the goal.
• 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, shop ventilation, or cleanup procedures appropriate for the material being sanded.
• Q: Is the CP5303-35 better for detail work or large panels?
  A: The 3.5" pad is better suited to spot repairs, contours, small panels, and detail sanding. For broad flat panels or faster coverage, a 5" or 6" random orbital sander may be a better fit.
• Q: What air supply does the CP5303-35 require?
  A: The tool is rated for 90 PSI / 6.3 bar and uses 17 CFM / 8 l/s at load. Use at least a 1/4" / 6 mm air hose and confirm the compressor can maintain airflow during continuous sanding.
