Powered by compressed air at 0.9 HP and a free speed of 12,000 RPM, this tool delivers consistent material removal on metal, weld seams, and masonry. The JAT-451 accepts a 5-inch wheel with a 7\/8-inch arbor and features a 5\/8-inch 11 UNC spindle thread. A spindle lock simplifies wheel changes, and the adjustable wheel cover allows repositioning for different work angles. Air consumption runs at 4 CFM, making it compatible with most shop compressor setups.\u003c\/p\u003e\n\u003cp\u003eThe JET 505451 is suited for fabrication shops, maintenance facilities, and job-site metalwork where an electric grinder is not practical or permitted. It connects through a 1\/4-inch NPT air inlet and is typically paired with a 3\/8-inch ID air hose. The 5-inch wheel diameter handles material stock removal, weld grinding, and edge prep on structural steel, pipe, and plate. Licensed tradespeople and experienced fabricators are the primary installers and operators of this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.9 HP pneumatic motor delivering 12,000 RPM free speed for consistent stock removal\u003c\/li\u003e\n  \u003cli\u003e5-inch wheel capacity with 5\/8-inch 11 UNC spindle thread for standard grinding and cutting discs\u003c\/li\u003e\n  \u003cli\u003eSpindle lock for fast, tool-assisted wheel changes\u003c\/li\u003e\n  \u003cli\u003eAdjustable wheel cover for repositioning to match work angle\u003c\/li\u003e\n  \u003cli\u003eLow 4 CFM air consumption compatible with typical shop compressors\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch NPT air inlet with 3\/8-inch ID hose recommendation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 5-inch grinding and cutting wheels with a 7\/8-inch arbor and a 5\/8-inch 11 UNC spindle interface.

Before mounting or changing wheels, disconnect the air supply and verify zero pressure in the line. Inspect wheels for cracks or damage before each use and ensure the rated RPM of the wheel meets or exceeds the tool free speed of 12,000 RPM. Follow applicable OSHA and ANSI B7.1 safety standards for abrasive wheel use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Size\u003c\/strong\u003e: 5 x 7\/8 x 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Thread\u003c\/strong\u003e: 5\/8 inch 11 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower\u003c\/strong\u003e: 0.9 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Speed\u003c\/strong\u003e: 12,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Consumption\u003c\/strong\u003e: 4 CFM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Inlet\u003c\/strong\u003e: 1\/4 inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAir Hose ID\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSound Pressure\u003c\/strong\u003e: 83 dB(A)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSound Power\u003c\/strong\u003e: 91 dB(A)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVibration Value\u003c\/strong\u003e: 2.4 m\/s²\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: JET\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 505451\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JET","offers":[{"title":"Default Title","offer_id":51525043585330,"sku":"505451","price":456.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29508f108a99c5a0c833312ceb9538e8.jpg?v=1785463145","url":"https:\/\/voomisupply.com\/products\/jet-505451-5-inch-angle-grinder-0-9-hp-12000-rpm","provider":"Voomi Supply","version":"1.0","type":"link"}
