Pro-source 5530003545PRO Air Die Grinder 0.3 Hp 1/4 Inch

Product Description

The PRO-SOURCE 5530003545PRO is a pneumatic angle die grinder designed for material removal, deburring, porting, and surface finishing in shop and field environments. Powered by compressed air at 90 psi and 4 CFM, it delivers 20,000 RPM through a 1/4-inch collet with 0.3 horsepower output. The rear exhaust directs air away from the work surface, keeping debris clear of the operator and workpiece. This tool is sized for use by machinists, pipefitters, welders, and maintenance technicians who need a compact, angle-style grinder for precision material work in tight clearances.

The angle handle configuration makes this die grinder well suited for contour grinding, weld blending, and deburring on metal pipe, castings, and fabricated assemblies. It fits standard 1/4-inch shank mounted points, carbide burrs, and abrasive bits available from most industrial supply sources. Typical applications include metal fabrication shops, maintenance and repair operations, and trade contractors working on pipe and mechanical systems where a straight grinder cannot access the work zone.

Key Features

• Angle handle design for access in confined or awkward work areas
• 20,000 RPM speed rated for efficient material removal with mounted abrasives
• 1/4-inch collet accepts standard carbide burrs and mounted grinding points
• Rear exhaust location keeps airflow directed away from the workpiece
• Operates at 90 psi with 4 CFM air consumption, compatible with most shop compressors
• Compact 0.3 HP pneumatic motor with no motor heat buildup during extended use

Compatibility

Designed as a general-purpose replacement or addition for pneumatic angle die grinder applications requiring a 1/4-inch collet and a standard 90 psi shop air supply.

Installation Notes

Installation and operation should be performed by a qualified technician familiar with pneumatic tooling. Before attaching or changing accessories, shut off the air supply and bleed any residual pressure from the line. Ensure the air supply is filtered, lubricated, and regulated to 90 psi before connecting. Always confirm the accessory shank diameter matches the 1/4-inch collet and that the accessory speed rating meets or exceeds the tool speed before operation.
