It features a 0.5000 inch mill diameter, a 5\/8 inch length of cut, and a 2-1\/2 inch overall length. The three-flute, right-hand spiral design runs at a 40-degree helix angle and carries an AlTiN (aluminum titanium nitride) finish, which improves heat resistance and tool life in dry or semi-dry cutting conditions. The micrograin carbide substrate provides the rigidity needed for aggressive material removal while maintaining edge sharpness. This is a centercutting tool, allowing for direct plunge entry into workpieces without a pre-drilled pilot hole.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling operations in ferrous and non-ferrous metals including hardened steels, stainless, cast iron, and titanium alloys where the AlTiN coating provides a thermal barrier. The stub length profile keeps deflection low during full-width slotting or side milling passes. Typical applications include profile milling, pocketing, slotting, and contouring on CNC machining centers and manual knee mills. It fits 1\/2 inch collets and milling chucks without adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eAlTiN finish extends tool life in high-temperature cutting environments\u003c\/li\u003e\n  \u003cli\u003eThree-flute, 40-degree right-hand spiral for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables direct plunge milling\u003c\/li\u003e\n  \u003cli\u003eStub length profile minimizes deflection in slotting and pocketing operations\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches for consistent fit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for 1\/2 inch shank square end mill applications using standard ER collets, end mill holders, or hydraulic chucks on CNC machining centers and manual mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully powered down and locked out before changing tooling. Seat the shank to the minimum engagement depth recommended for the holder type being used, and verify runout with a dial indicator before beginning a cut. Do not exceed the rated depth of cut for the material being machined.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.6250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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: 0.25 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: 12179741\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737620382002,"sku":"12179741","price":89.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/feb88271de97301235f4dbf267e12249.jpg?v=1788791501","url":"https:\/\/voomisupply.com\/products\/accupro-12179741-square-end-mill-1-2-in-3-flute-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
