Built for aggressive spot sanding, surface blending, and compact-pad finishing work, the Chicago Pneumatic CP5318-30H Random Orbital Sander uses a 3" hook-and-loop pad to reach smaller work areas that larger 5" and 6" sanders cannot handle as easily. Its 12,000 RPM free speed keeps the abrasive moving quickly across metal, body filler, primer, and coated surfaces, while the manufacturer technical data lists a 9/16" / 14 mm orbit, giving this model a stronger cutting action than fine-finish 3/32" orbit sanders.
Part of the CP53 Series, the CP5318-30H uses a 0.3 hp / 210 W oil-free motor, helping protect surface preparation work from oil contamination. The non-vacuum configuration is suited for applications where dust extraction is handled separately or where onboard collection is not required. With a compact 3" circular pad and higher-orbit sanding motion, this tool fits spot repair, edge feathering, localized material removal, and pre-polishing operations in body shops, maintenance areas, and production finishing stations.

Features:
- 3" circular pad format gives the user better access for spot sanding, localized repair work, and smaller surface areas.
- Hook-and-loop pad attachment allows faster abrasive changes than adhesive-backed PSA sheets when switching grits during prep work.
- 9/16" orbit provides more aggressive sanding action than fine-orbit models, helping remove material faster on suitable surfaces.
- 0.3 hp / 210 W oil-free motor supports efficient sanding while helping reduce the risk of oil contamination on finish-sensitive work.
- Non-vacuum layout keeps the tool simple for shops that use separate dust-control methods or do not require built-in extraction.
- 5/8-24 UNF spindle thread supports compatible CP pads and accessories designed for this sander platform.
- Soft-grip body design helps maintain control during spot repair, edge blending, and compact-area sanding tasks.
- Orbital motion helps produce smoother surface preparation than straight-line sanding when the correct abrasive grit and technique are used.
IMPORTANT: Use only sanding discs, pads, and polishing accessories compatible with the tool, pad size, spindle thread, attachment style, and operating speed. Never use damaged abrasives. Always wear appropriate eye, face, respiratory, hearing, and body protection when sanding or polishing.
Applications:
- Autobody and collision repair: spot sanding, feathering repair edges, shaping body filler, and preparing small panel areas before refinishing.
- Paint and coating preparation: removing localized imperfections, smoothing primer transitions, and preparing compact surfaces for the next finish step.
- Metal fabrication: blending small surface marks, cleaning up edges, and preparing metal parts before paint, coating, or assembly.
- Industrial maintenance and MRO: sanding access panels, machine covers, guards, and localized repair areas where a larger sander is too broad.
- General shop finishing: compact-pad sanding and pre-polishing tasks where a 3" random orbital tool provides better control around contours and edges.
FAQs:
- Q: What is the advantage of the 3" pad size?
A: A 3" pad is useful for spot repairs, tight areas, contours, and smaller workpieces where a 5" or 6" sander may remove too much surrounding material. It gives the user more control when sanding localized defects or working near edges. - Q: What does hook-and-loop mean?
A: Hook-and-loop sanding discs attach to the pad with a reusable fastening surface, similar to a mechanical grip. This makes abrasive changes faster than PSA adhesive sheets when moving through multiple grits. - Q: Is the CP5318-30H a vacuum sander?
A: No. The CP5318-30H is a non-vacuum model. Use appropriate shop dust control, PPE, and cleanup procedures when sanding materials that create airborne dust. - Q: Is a 9/16" orbit good for final finishing?
A: A 9/16" orbit is more aggressive than fine-finish orbit sizes such as 3/32". It is better suited for faster material removal, spot repair, and blending work; final finish quality depends on abrasive grit, material, pressure, and sanding technique. - Q: What air supply does this sander require?
A: The catalog lists 23 CFM / 11 l/s air consumption at load and 90 PSI / 6.3 bar operating pressure. Use a properly regulated air system that can support the tool during sustained sanding.
