Dynabrade 54424 Air Disc Sander 0.7 Hp 3 Inch 18000 Rpm

Product Description

The DYNABRADE 54424 is a pneumatic handheld disc sander designed for surface finishing, paint prep, and material removal in professional trade and industrial environments. Powered by compressed air at 90 psi and consuming 40 CFM, this tool delivers 18,000 RPM with 0.7 horsepower through a 3-inch sanding disc. The rear exhaust directs airflow away from the work surface, keeping the area clear during operation. The 1/4 NPT inlet provides a standard connection to shop air supply lines. At 4 pounds, the tool is balanced for extended handheld use on metal fabrication, bodywork, woodworking, and general surface preparation tasks.

The 54424 is suited for production shops, fabrication facilities, and field service applications requiring a compact, high-speed disc sander. The 3-inch pad size makes it effective in tight contours and smaller work areas where larger orbital or straight-line sanders cannot reach. It ships with the 51347 Medium Density Locking-Type Backup Pad, 3-inch diameter, included in the box. This tool is typically used by metalworkers, auto body technicians, pipefitters, and maintenance professionals who rely on pneumatic tooling.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with pneumatic tool safety practices. Before connecting to an air supply, confirm the line pressure does not exceed 90 psi and that an inline filter-regulator-lubricator is present to protect the tool motor. Verify all disc and pad hardware is secured before operation, and inspect the backup pad for wear or damage prior to each use. Always disconnect the air supply before changing discs or performing any maintenance.
