Proto J325AGS Air Die Grinder 0.30 Hp 1/4 Inch Collet

Product Description

The PROTO J325AGS is a straight-handle air die grinder built for grinding, deburring, porting, and surface prep in trade and industrial applications. Running at 30000 RPM with 0.30 HP output, it draws 2.70 CFM at 90 psi operating pressure. The 1/4 inch collet accepts standard mounted points, carbide burrs, and grinding wheels. Rear exhaust directs spent air away from the work surface and the operator. At 1 pound, it is light enough for extended overhead or confined-space work. Licensed mechanics, pipefitters, and fabricators reach for this tool when a straight-body profile is required for access to tight geometries.

The J325AGS fits residential and commercial maintenance shops, fabrication facilities, automotive service bays, and pipe and mechanical rooms where compressed air is already in use. Its straight die grinder profile suits inline drilling approaches and straight-bore work that angled grinders cannot reach cleanly. Any shop or service truck running a compressor capable of sustaining 90 psi and adequate CFM can put this tool to immediate use.

Key Features

• 30000 RPM free speed for aggressive material removal on metals and composites
• 1/4 inch collet accepts the most common mounted points and carbide burr shank size
• 0.30 HP motor balanced for light weight without sacrificing cutting speed
• Rear exhaust directs air discharge away from the operator and work area
• Straight handle profile provides access in confined or inline work positions
• 2.70 CFM air consumption is compatible with mid-range shop compressors

Compatibility

Designed as a standard straight die grinder accepting 1/4 inch shank accessories including mounted grinding points, carbide burrs, and small abrasive wheels commonly used in metal fabrication and mechanical service applications.

Installation Notes

A licensed mechanic or qualified technician should verify the compressed air supply meets the 90 psi and minimum CFM requirements before operation. Always depressurize and disconnect the air line before changing collet accessories. Inspect the collet and collet nut for wear before each use and tighten securely to prevent accessory ejection at speed. Follow OSHA and tool manufacturer wheel and burr speed ratings to ensure accessories are rated at or above the tool free speed.
