It features a 1\/2 inch diameter with a 5\/8 inch length of cut and runs five flutes with a 38-degree helix angle for aggressive chip evacuation and smooth surface finishes. The AlTiCrN coating provides heat resistance and extended tool life in demanding cutting conditions. A variable index geometry reduces harmonic vibration during cuts. Machinists and tool-and-die professionals install this end mill in CNC machining centers and manual mills requiring a rigid, single-end cutting tool in a 1\/2 inch shank configuration.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for applications where high material removal rates and fine finishes are required in a single-end configuration. The extended reach of 1.5 inches allows access to deeper pockets and stepped features without tool changes. The right-hand flute direction and right-hand cutting orientation are standard for conventional CNC spindle setups. It is part of the ACCUPRO HS series, which targets production machining environments where tool consistency and coating durability are priorities. The centercutting capability allows direct plunge entry without pre-drilling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin substrate for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiCrN coating for high-heat and abrasion resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003e5 flutes with 38-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces chatter and vibration\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling\u003c\/li\u003e\n\u003cli\u003eExtended reach of 1.5 inches for deep pocket and stepped feature access\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for solid carbide square end mills in the 1\/2 inch shank class, compatible with standard ER collet chucks, shrink-fit holders, and side-lock holders accepting 1\/2 inch shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols and machine tool manufacturer guidelines. Secure the shank to the minimum recommended insertion depth in a clean, burr-free collet or tool holder before tightening. Verify spindle RPM and feed rate against the material being cut before engaging the workpiece. Never exceed the rated depth of cut for the flute length.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.6250 inches (15.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4 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: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.5000 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\u003c\/strong\u003e: AlTiCrN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\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\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 312182\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51735667638578,"sku":"312182","price":150.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b8b1130018d2d99c19436435352194cb.jpg?v=1788773546","url":"https:\/\/voomisupply.com\/products\/accupro-312182-square-end-mill-1-2-in-5-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
