Dynabrade 54374 Angle Air Die Grinder 0.7 Hp 12000 Rpm

Product Description

The DYNABRADE 54374 is a 1/4 inch angle air die grinder designed for precision material removal, deburring, porting, and surface finishing in industrial and trade environments. Powered by compressed air at 90 psig, it delivers up to 0.7 horsepower and operates at 12,000 RPM with a speed range spanning 10,000 to 17,999 RPM. The lever throttle provides responsive speed control during extended use. At 3.8 pounds and with a compact angled head profile, this grinder is suited for work in confined spaces where inline tools cannot reach. A rear exhaust design directs air away from the work surface and the operator. Licensed machinists, toolroom technicians, and industrial maintenance mechanics are the primary users.

The 54374 is used in manufacturing, fabrication, and maintenance applications requiring controlled grinding or finishing at tight angles. Typical scenarios include die and mold work, weld cleanup, port blending, and burr removal on metal components. The included 1/4 inch and 6 mm collet inserts allow use with standard die grinder bits, carbide burrs, mounted points, and cut-off wheels rated for the tool speed. It is appropriate for both production floor and job-site use wherever a regulated compressed air supply at 90 psig and adequate CFM delivery are available. Air consumption is rated at 40 CFM, so supply line and compressor sizing should be confirmed before installation.

Key Features

• Angle head geometry allows access to recessed and confined work areas
• Lever throttle provides precise speed modulation during operation
• Includes both 1/4 inch and 6 mm collet inserts for broad accessory compatibility
• Rear exhaust routes spent air away from the operator and workpiece
• CE Certified and EAC Certified for compliance in applicable markets

Compatibility

Designed for use with standard 1/4 inch shank and 6 mm shank die grinder accessories including carbide burrs, mounted grinding points, and rotary files rated for speeds up to the tool maximum. Verify that all accessories are rated at or above the maximum free speed before use.

Installation Notes

Installation and operation of pneumatic die grinders should be performed by qualified personnel familiar with compressed air systems and abrasive tool safety. Shut off and bleed the air supply line before connecting or disconnecting the tool. Confirm that the supply line delivers a minimum of 40 CFM at 90 psig to maintain rated performance; undersized lines will reduce speed and torque. Always inspect accessories for cracks or damage before mounting, and ensure the spindle is secured before applying air pressure.
