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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.30 HP output suitable for deburring, grinding, and surface finishing tasks\u003c\/li\u003e\n\u003cli\u003e28000 RPM rated speed for fast material removal with standard mounted accessories\u003c\/li\u003e\n\u003cli\u003eRear exhaust directs airflow away from the work area and operator\u003c\/li\u003e\n\u003cli\u003e1\/4-inch collet accepts industry-standard burrs, bits, and mounted grinding points\u003c\/li\u003e\n\u003cli\u003eStraight handle design provides control in confined or recessed work areas\u003c\/li\u003e\n\u003cli\u003eLightweight at 1.5 pounds reduces fatigue during extended operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/4-inch shank rotary accessories including carbide burrs, mounted grinding stones, and surface conditioning discs.

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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorsepower\u003c\/strong\u003e: 0.30 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeed\u003c\/strong\u003e: 28000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Consumption\u003c\/strong\u003e: 2.70 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Pressure\u003c\/strong\u003e: 90 psi (6.20 bar \/ 620 kPa)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCollet Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExhaust Location\u003c\/strong\u003e: Rear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.07 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.89 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112700\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PROTO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: J325AGSE\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51544599560498,"sku":"J325AGSE","price":157.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae21c96089cc1b53c7012e58cc8ebb9c.jpg?v=1785931038","url":"https:\/\/voomisupply.com\/products\/proto-j325agse-air-die-grinder-0-30-hp-1-4-inch-collet","provider":"Voomi Supply","version":"1.0","type":"link"}
