Dynabrade 52222 Air Die Grinder 0.5 Hp 1/4 Inch Collet

Product Description

The DYNABRADE 52222 is a pneumatic angle die grinder built for material removal, deburring, porting, and surface finishing in industrial and fabrication environments. It runs on compressed air at 90 psi and delivers 0.5 horsepower at a rated speed of 20000 RPM, with a speed range spanning 18000 to 24999 RPM. The 1/4-inch collet accepts standard mounted points, carbide burrs, and abrasive wheels. Rear exhaust routes air away from the workpiece, keeping the work zone clear of debris and coolant. Overall length is 8.125 inches. Licensed mechanics, machinists, fabricators, and pipefitters are the primary installers and operators.

This grinder is suited for tight-clearance work where a straight grinder cannot reach. The 7-degree offset angle handle positions the spindle at an angle to the body, making it practical for port work, weld blending in confined areas, and die and mold finishing. It is commonly used in automotive shops, aerospace fabrication, metal fabrication facilities, and maintenance repair operations. Air consumption is 24.99 CFM at 90 psi, so an adequately sized compressor and supply line are required to maintain consistent tool performance.

Key Features

• Compact 8.125-inch overall length for use in tight work envelopes

Compatibility

Designed for use with 1/4-inch shank mounted points, carbide burrs, and rotary files compatible with angle die grinders operating at up to 20000 RPM. Verify accessory RPM rating meets or exceeds tool speed before use.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with pneumatic tool safety. Shut off and bleed compressed air from the supply line before changing collets or accessories. Ensure the air supply is regulated to 90 psi and that the supply line and fittings are rated for the required CFM to avoid speed drop under load. Inspect the collet and accessory shank for wear or damage before each use, and never exceed the RPM rating marked on the abrasive or burr.
