Dynabrade 52515 Air Handheld Disc Sander 4-4.5 in 15000 Rpm

Product Description

The DYNABRADE 52515 is a pneumatic handheld disc sander designed for surface grinding, material removal, and finishing work in industrial and fabrication environments. It operates at 15,000 RPM and accepts disc sizes from 4 to 4-1/2 inches, making it well suited for work in moderately confined areas where a full-size grinder is too large. The tool runs on compressed air at 90 psi with an airflow requirement of 33 CFM and draws power through a 1/4 NPT inlet. Output is rated at 0.55 horsepower. Exhaust exits from the rear of the tool, directing air and debris away from the work surface and the operator. The package includes a 07184 guard.

This disc sander is used in metal fabrication shops, automotive body work, pipeline work, and general industrial maintenance. Its compact disc capacity and high RPM make it effective for edge blending, weld seam cleanup, and surface preparation on steel, aluminum, and similar materials. The rear exhaust design helps keep the work area visible during operation. Licensed tradespeople and industrial maintenance technicians are the primary installers and operators of this tool.

Installation Notes

Disconnect the air supply before mounting or changing discs. Confirm the shop air system delivers at least 90 psi and 33 CFM at the tool inlet to achieve rated performance. Inspect the disc, backing pad, and guard for damage before each use in accordance with ANSI B11 and OSHA 1910.243 abrasive tool standards. Always allow the tool to reach free speed before contacting the work surface.
