Dynabrade 52662 Air Die Grinder 1 Hp 1/4 Inch Collet

Product Description

The DYNABRADE 52662 is a straight-handle pneumatic die grinder designed for material removal, deburring, grinding, and surface preparation in industrial and trade environments. Powered by compressed air at 90 psi, it delivers 1 horsepower and a governed speed of 3400 RPM, with a free speed capability up to 9999 RPM. The tool accepts a 1/4 inch collet, making it compatible with the wide range of carbide burrs, mounted points, and grinding bits standard in metal fabrication and finishing work. At 3.1 pounds, it balances well for extended use. The rear exhaust location directs air away from the workpiece and operator, reducing debris blowback during operation.

This grinder is suited for use in metal fabrication shops, automotive repair, aerospace maintenance, and general manufacturing environments. Typical applications include weld seam blending, port matching, gasket surface cleanup, and burr removal on castings or machined components. The straight handle profile gives the operator direct in-line control for precision work in tight access areas. It is installed and operated by machinists, pipefitters, tool and die technicians, and industrial maintenance mechanics who require a reliable pneumatic grinder for sustained production use.

Compatibility

Designed for use with standard 1/4 inch shank carbide burrs, mounted grinding points, and rotary abrasive accessories. Requires a compressed air supply capable of delivering 43 CFM at 90 psi with appropriate air line filtration and lubrication per tool manufacturer guidelines.

Installation Notes

Connection to the air supply should be made by a qualified operator familiar with pneumatic tool safety practices. Shut off and bleed the air line before attaching or changing collet accessories. Ensure the air supply includes an in-line filter, regulator, and lubricator set to the correct pressure before operation. Operate within the rated air pressure of 90 psi to avoid overspeed conditions.
