Dynabrade 49425 Angle Air Die Grinder 0.40 Hp

Product Description

The DYNABRADE 49425 is a right angle air die grinder built for professional grinding, deburring, and surface finishing tasks in industrial and trade environments. Powered by compressed air at 90 psi and 26.00 CFM, it delivers 3,200 RPM through a 1/4-inch collet with a lever-style throttle for controlled operation. The rear exhaust design directs airflow away from the work surface, keeping the workpiece clean during use. At 0.40 HP and a compact 7.7-inch overall length, this grinder is well suited for tight access areas on metal fabrication and maintenance work. Licensed machinists, pipefitters, and tool-and-die professionals are the primary users.

The 49425 is designed for use with carbide burrs, mounted points and discs, and rotary files. Its 90-degree angle head configuration allows access to recessed areas and inside profiles where inline grinders cannot reach. Typical applications include weld blending, port work, mold finishing, and general deburring on metal, composite, and hard plastic workpieces in shop and field environments. The lever throttle provides variable speed control suited to both aggressive stock removal and fine finishing passes.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with pneumatic tool safety practices. Before connecting to an air supply, verify the line pressure does not exceed 90 psi and that the air supply is equipped with a filter, regulator, and lubricator as appropriate. Inspect the collet and accessory shank for wear or damage before mounting any grinding attachment. Always power down and depressurize the tool before changing collet accessories.
