Built from powdered metal, this tool delivers consistent edge toughness across a range of ferrous and non-ferrous workpiece materials. The 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces during peripheral and slot milling. With a 5\/8 inch cutting diameter, 1-5\/8 inch length of cut, and 3-3\/4 inch overall length, this end mill suits general-purpose CNC and manual milling applications. It is centercutting, allowing plunge entry directly into the workpiece. The uncoated finish makes it suitable for use with cutting fluids and compatible with regrinding services.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in vertical machining centers, knee mills, and similar setups where a 5\/8 inch straight shank is the standard holding interface. The 3-flute configuration balances chip clearance with tool rigidity, making it practical for slotting, profiling, and shoulder milling in job shops and production environments. Machinists and CNC operators working with aluminum, mild steel, and similar materials will find this a reliable general-purpose tool. The right-hand cut and right-hand spiral flute orientation match standard spindle rotation on most milling machines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8 inch cutting diameter with a 1-5\/8 inch length of cut for mid-depth milling operations\u003c\/li\u003e\n  \u003cli\u003ePowdered metal construction provides consistent hardness and edge retention across the tool\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle promotes smooth cutting action and effective chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003e3-flute spiral geometry balances chip room and core strength for general milling tasks\u003c\/li\u003e\n  \u003cli\u003eUncoated surface is compatible with standard cutting lubricants and regrinding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose square end mill compatible with standard 5\/8 inch end mill holders, collet chucks, and Weldon-style holders used on vertical machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by a machinist or CNC operator using a standard end mill holder or collet sized for a 5\/8 inch straight shank. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before changing tooling. Verify tool runout with a dial indicator after installation to confirm proper seating. Follow the machine manufacturer and tooling manufacturer guidelines for speed and feed parameters based on workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inch (1.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.003 \/ -0.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.9 pounds\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 39527\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727762424114,"sku":"39527","price":53.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b96239186b1cec6fc819105a7723431c.jpg?v=1788681922","url":"https:\/\/voomisupply.com\/products\/accupro-39527-square-end-mill-5-8-inch-3-flute-powdered-metal","provider":"Voomi Supply","version":"1.0","type":"link"}
