Proto J325AGSE Air Die Grinder 0.30 Hp 1/4 Inch Collet

Product Description

The PROTO J325AGSE is a straight-handle air die grinder built for material removal, deburring, and surface prep in professional trade and industrial environments. It runs on compressed air at 90 psi and delivers 0.30 horsepower at a rated speed of 28000 RPM. Air consumption is 2.70 CFM, making it compatible with standard shop compressor setups. The rear exhaust design routes spent air away from the work surface and operator, reducing debris blowback. The 1/4-inch collet accepts a wide range of standard grinding bits, burrs, and mounted points. Licensed HVAC, mechanical, and fabrication professionals rely on this tool for precision grinding in confined spaces where electric tools are impractical.

The J325AGSE is suited for use in commercial and industrial shop environments, automotive service bays, mechanical rooms, and fabrication settings. Its straight die grinder configuration makes it well-suited for internal grinding, port work, and weld cleanup in tight clearances. The lightweight, compact body at 7.2 inches in length and 1.5 pounds reduces operator fatigue during extended use. It is a practical fit for any trade professional requiring a reliable, high-speed rotary air tool.

Installation Notes

Installation and use should be performed by a qualified technician familiar with pneumatic tool safety practices. Before connecting or disconnecting air fittings, depressurize the supply line and verify the air source is shut off. Ensure the air supply is clean and dry, using an inline filter-regulator-lubricator (FRL) unit to extend tool life and maintain consistent performance. Follow applicable OSHA and shop safety guidelines for eye protection and RPM-rated accessory selection.
