Built for broad sanding work where faster material removal, quick abrasive changes, and dust-control configuration are important, the Ingersoll Rand R036C-S3-HL Premium Random Orbital Sander combines a 6″ hook-and-loop pad with a 5/16″ orbit for surface preparation on wood, composites, fiberglass, sheet metal, and similar shop materials. Random orbital sanding actionthe pad moves in overlapping orbits rather than one fixed circular pathhelps reduce directional sanding marks, while the larger 5/16″ orbit removes material more aggressively than the 3/32″ and 3/16″ orbit versions.The R036C-S3-HL uses a 0.3 HP motor and 13,000 RPM free speed to support productive sanding during primer leveling, coating prep, panel work, and general stock removal. Its 6″ pad size covers larger surfaces efficiently, while the hook-and-loop pad accepts compatible abrasive discs for faster grit changes during multi-step sanding. This Premium Random Orbital Sander is supplied in a self-generating vacuum configuration, identifying it as a dust-control version within the family.Type: Random Orbital Sander | Series: Premium Random Orbital Sander | Model: R036C-S3-HL | Pad Size: 6″ / 152 mm | Pad Style: Hook & Loop | Orbit Diameter: 5/16″ / 8 mm | Max Free Speed: 13,000 RPM | Rated Power: 0.3 HP / 0.22 kW | Vacuum Configuration: Self-Generating | Weight: 1.9 lb / 0.86 kg | Length: 6.69″ / 170 mm | Vibration: 4.6 m/s | Vibration Uncertainty K: 1.5 m/s | Sound Pressure: 82.3 dB(A) | Sound Power: 93.3 dB(A)Features:0.3 HP motor provides sanding power for coating prep, primer leveling, surface conditioning, and general material removal tasks.13,000 RPM free speed supports fast sanding action across wood, composites, fiberglass, sheet metal, and similar materials.5/16″ orbit delivers the most aggressive orbit option in this Premium Random Orbital Sander family for faster removal and surface leveling.6″ hook-and-loop pad accepts compatible hook-and-loop abrasive discs and provides broad coverage per pass on larger work surfaces.Self-generating vacuum configuration supports dust-control setups for particle removal during sanding.Extended handle provides additional support and hinges up for access to the air inlet.Recessed paddle helps avoid pinch points, while the tucked-away regulator allows quick changes during use.Contoured housing and ultimate comfort grip help the tool fit the users hands comfortably during extended sanding periods.Applications:Autobody and refinishing: Sanding larger panels, leveling primer, preparing repaired areas, and removing material before finer finishing steps.Woodworking and cabinet shops: Sanding doors, tabletops, cabinet panels, furniture parts, and broad wood surfaces using a 6″ hook-and-loop abrasive format.Composite and fiberglass work: Leveling molded parts, smoothing fiberglass panels, and preparing composite surfaces before coating or paint.Metalworking and fabrication: Surface cleanup, sheet metal prep, and sanding parts before primer, coating, or protective finish.Industrial maintenance and MRO: Refurbishment, coating-prep, and surface conditioning tasks where larger orbit action, quick disc changes, and self-generating vacuum configuration are useful.FAQs:Q: What is the R036C-S3-HL best used for?A: The R036C-S3-HL is suited for faster sanding and material removal on larger surfaces. Its 6″ pad covers broad areas efficiently, while the 5/16″ orbit provides a more aggressive sanding pattern than smaller-orbit models.Q: What does a 5/16″ orbit mean?A: Orbit diameter is the size of the pads sanding motion. A 5/16″ orbit creates a larger sanding pattern, which helps remove material faster but may leave a coarser scratch pattern than 3/32″ or 3/16″ orbit sanders.Q: What is the difference between the R036C-S3-HL and R036C-S3?A: Both models use a 6″ pad diameter, 5/16″ orbit, 13,000 RPM free speed, 0.3 HP motor, self-generating vacuum configuration, 1.9 lb weight, 6.69″ length, 4.6 m/s vibration, and the same listed sound levels. The R036C-S3-HL uses a hook-and-loop pad, while the R036C-S3 uses a vinyl pad.Q: How does this model compare with the R036C-C3-HL?A: Both models use a 6″ hook-and-loop pad, 5/16″ orbit, 13,000 RPM free speed, 0.3 HP motor, and the same listed vibration, weight, length, and sound values. The R036C-S3-HL is the self-generating version, while the R036C-C3-HL is listed as vacuum ready for connection to a compatible external dust extraction system.Q: What abrasive discs fit this model?A: Use compatible 6″ hook-and-loop abrasive discs matched to the material, removal rate, and finishing step. Confirm the abrasive backing style, grit, and speed rating before use. body{margin:0;padding:0;overflow-x:hidden;} .spec-accordion{width:100%;max-width:1100px;margin:1em
