Dynabrade 52635 Air Handheld Disc Sander 1.3 Hp 5 in

Product Description

The DYNABRADE 52635 is a pneumatic handheld disc sander built for surface preparation, material removal, and finishing work in demanding trade environments. It runs on compressed air at 90 psi and delivers 12,000 RPM through a 5-inch pad, powered by a 1.3 hp motor. Air consumption is 43 CFM, and the tool connects via a 3/8 NPT inlet fitting. The 52635 ships with a 51150 backing pad and mounting hardware, making it ready for disc installation out of the box. It is suited for metal fabrication shops, automotive body work, industrial maintenance, and general construction finishing applications.

This sander accepts 5-inch abrasive discs and is used in both shop and field settings where a compact, high-speed pneumatic disc sander is required. Typical applications include weld seam blending, rust and coating removal, and surface prep before painting or bonding. The 3/8 NPT air inlet is a standard connection found on most shop air systems, allowing straightforward integration into existing compressed-air setups. The tool is designed for use by skilled tradespeople in fabrication, maintenance, and finishing roles.

Installation Notes

Installation and operation should be performed by personnel familiar with pneumatic power tools and shop air systems. Disconnect the air supply before mounting or changing abrasive discs. Verify that the compressed-air source meets the 90 psi and 43 CFM requirements before connecting, as insufficient flow will reduce tool performance. Follow applicable OSHA and manufacturer safety guidelines for abrasive disc RPM ratings — never mount a disc rated below the tool free speed of 12,000 RPM.
