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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e30,000 RPM no-load speed for high-speed material removal and finishing\u003c\/li\u003e\n\u003cli\u003eLever throttle provides positive, variable control during operation\u003c\/li\u003e\n\u003cli\u003eRear exhaust directs airflow away from the work surface\u003c\/li\u003e\n\u003cli\u003eIncludes both 1\/4 inch (50013) and 6 mm (50016) collet inserts\u003c\/li\u003e\n\u003cli\u003eCompact straight-body profile for access in tight workspaces\u003c\/li\u003e\n\u003cli\u003eCE Certified and EAC Certified for international compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eAccepts standard 1\/4 inch shank rotary tooling and 6 mm shank accessories.
