The tool measures 0.5 inches in diameter with a 2-inch length of cut and a 4-inch overall length, making it a long-series configuration suitable for applications requiring extended reach into deep pockets or slots. The 40-degree spiral helix angle promotes aggressive chip evacuation and smooth cutting action. An AlTiN (Aluminum Titanium Nitride) coating provides thermal resistance and extended tool life when cutting ferrous and hardened materials. Licensed machinists and CNC operators are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use on vertical and horizontal machining centers, CNC mills, and manual knee mills where a 0.5-inch shank is accepted. The long flute length supports full-depth slotting, profiling, and pocket milling in steel, stainless steel, cast iron, and similar hard materials. The centercutting design allows plunge entry directly into the workpiece without a pre-drilled pilot hole. Right-hand cut and right-hand flute geometry match standard spindle rotation on most commercial machine tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating extends tool life by reducing heat transfer into the carbide substrate\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eLong-series flute length of 2 inches supports deep pocket and slot milling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute match standard CNC spindle configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct application tool for CNC machining centers and manual mills accepting a 0.5-inch straight shank end mill holder or collet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. The shank must be fully seated and properly torqued in a clean, undamaged collet or end mill holder before spindle engagement. Inspect the collet and holder for runout before use, as excessive runout accelerates tool wear and degrades surface finish. Always confirm spindle rotation direction matches the right-hand cut orientation of this tool before initiating a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\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\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\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\u003eLength Type\u003c\/strong\u003e: Long Series\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: 12181733\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727401091378,"sku":"12181733","price":153.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9d6d74c411f420705254f69059bb5ae.jpg?v=1788677408","url":"https:\/\/voomisupply.com\/products\/accupro-12181733-square-end-mill-0-5-in-2-flute-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
