Built from micrograin solid carbide with an AlTiN (aluminum titanium nitride) finish, this tool delivers excellent heat resistance and wear life in ferrous and hardened materials. The 5\/8 inch diameter cutter features 7 flutes with a 37.5-degree spiral helix angle, producing smooth chip evacuation and reduced chatter at aggressive feed rates. The centercutting geometry allows plunge entry directly into the workpiece. At 6 inches overall length with a 3\/4 inch length of cut, this end mill is suited for reach-critical pocketing and profiling operations. It weighs approximately 0.961 pounds.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in production machining environments operated by machinists, CNC programmers, and tool-and-die professionals. The extended reach design, with a reach length of 3-1\/8 inches, makes it well suited for deep cavity milling, tall workpiece profiles, and multi-setup part programs where standard-reach tooling cannot reach the floor of a feature. The right-hand cut and right-hand flute configuration is compatible with conventional CNC machining center spindles. The AlTiN coating performs best in dry or minimal-lubrication high-speed machining of steel, stainless steel, and cast iron.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eAlTiN finish for elevated heat resistance in dry and high-speed cutting\u003c\/li\u003e\n  \u003cli\u003e7-flute design increases material removal rate and surface finish quality\u003c\/li\u003e\n  \u003cli\u003e37.5-degree helix angle reduces cutting forces and vibration\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows direct plunge milling\u003c\/li\u003e\n  \u003cli\u003eExtended reach at 3-1\/8 inches for deep cavity and tall-wall applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard CNC machining centers and manual mills accepting a 5\/8 inch straight shank toolholder, collet, or end mill adapter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine in a safe, locked-out state. Confirm toolholder bore tolerance is compatible with the shank diameter tolerance of -0.0001\/-0.0004 inches before seating. Verify runout with a dial indicator after clamping to avoid premature edge failure. Follow the machine manufacturer and tooling manufacturer guidelines for speeds, feeds, and depth of cut for the specific 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: 7\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\u003eFinish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 0.7000 - 0.8000 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: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 3-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37.5 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\u003eExtended Reach\u003c\/strong\u003e: Yes\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\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\u003eWeight\u003c\/strong\u003e: 0.961 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: 12178699\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733273116978,"sku":"12178699","price":356.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a682dad2f87c0a02a40c825283a24ab5.jpg?v=1788753461","url":"https:\/\/voomisupply.com\/products\/accupro-12178699-square-end-mill-5-8-in-7-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
