Dynabrade 48203 Straight Air Die Grinder 0.4 Hp 30000 Rpm

Product Description

The DYNABRADE 48203 is a straight air die grinder designed for precision material removal, deburring, porting, and surface finishing in industrial and trade environments. It runs at 30,000 RPM on 0.4 horsepower and requires 90 psi supply pressure at 23 CFM airflow. The lever-style throttle gives operators direct speed control during close-tolerance work. Rear exhaust directs spent air away from the workpiece, keeping debris clear of the cutting zone. The 48203 ships with both a 1/4 inch and a 6 mm collet insert, making it ready for standard tooling used in metalworking, fabrication, and maintenance repair operations.

This grinder fits residential and commercial maintenance shops, metal fabrication facilities, automotive service bays, and industrial manufacturing lines. It is suited for tasks such as weld cleanup, die grinding, gasket surface prep, and porting work on ferrous and non-ferrous metals. Any application requiring high-speed rotary tooling at a 1/4 inch or 6 mm arbor is a typical install scenario. A licensed or trained pneumatic tool technician or machinist would be the primary user in a production or MRO setting.

Installation Notes

A qualified pneumatic tool technician should connect this grinder to a properly regulated air supply before use. Shut off and bleed the air line before changing collets or tooling. Verify supply pressure is set to 90 psi and that the compressor can sustain 23 CFM to maintain rated performance. Always follow applicable OSHA and ANSI B186.1 standards for portable pneumatic tool operation and personal protective equipment.
