Built from micrograin carbide with an AlTiN (aluminum titanium nitride) finish, this tool delivers excellent wear resistance and heat tolerance in high-speed cutting environments. It features a 5\/8 inch cutting diameter, a 1-1\/4 inch length of cut, and a 40-degree helix angle with spiral flutes oriented in a left-hand direction. The right-hand cutting geometry and centercutting capability allow for both peripheral and plunge milling. Machinists, toolroom technicians, and CNC operators working in steel, stainless, and similar alloys will find this end mill suited to production and precision work alike.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in vertical and horizontal milling machines, machining centers, and CNC mills. Its 5\/8 inch shank diameter and 3-1\/2 inch overall length make it a standard-reach tool appropriate for most common setups where extended reach is not required. The four-flute configuration balances material removal rate with surface finish quality, making it suitable for finishing and moderate roughing passes. The AlTiN coating extends tool life in ferrous materials, particularly in dry or semi-dry cutting conditions where heat buildup is a concern.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eAlTiN finish provides high heat and oxidation resistance for extended tool life\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle with spiral, left-hand flute orientation reduces chatter and improves chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge milling in addition to peripheral cutting\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with four flutes balances stock removal and surface finish\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches and shank tolerance of -0.0001 \/ -0.0004 inches for precise fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for milling setups requiring a 5\/8 inch diameter, 5\/8 inch shank, solid carbide square end mill in ER collet chucks, end mill holders, or similar 5\/8 inch bore toolholding systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinist or toolroom personnel. Ensure the toolholder bore is clean and free of chips or debris before seating the shank. Confirm runout with a dial indicator after clamping to verify concentricity within acceptable limits. Follow machine manufacturer guidelines and applicable shop safety procedures when setting tool offsets and initiating cutting passes.\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\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inch (1.2500 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\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inch (3.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.561 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: 12176981\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747541549362,"sku":"12176981","price":192.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/657105b04428809345c41edbcfc55ad2.jpg?v=1788882204","url":"https:\/\/voomisupply.com\/products\/accupro-12176981-square-end-mill-5-8-inch-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
