It carries a 0.5-inch (12.70 mm) cutting diameter and features five flutes with a 38-degree helix angle for aggressive chip evacuation and smooth surface finishes. The AlTiCrN coating provides heat and wear resistance, making this end mill well suited to hard materials and high-speed cutting applications. At 6 inches overall length with a 0.625-inch length of cut, it offers extended reach capability. Right-hand cutting and right-hand flute direction are standard. This tool is installed by machinists and CNC operators in job shop, production, and tool-and-die settings.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for milling operations on ferrous and non-ferrous metals where tool life and dimensional accuracy are priorities. The variable index geometry reduces harmonic vibration during cutting, improving finish quality and extending tool life in interrupted or deep-pocket operations. The single-end configuration is standard for replacement after wear. With a 0.5-inch shank diameter, it seats directly into standard 0.5-inch collets, end mill holders, or shrink-fit tooling. It is appropriate for vertical machining centers, horizontal mills, and manual knee mills equipped for carbide tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFive-flute spiral design promotes high material removal rates and improved surface finish\u003c\/li\u003e\n\u003cli\u003eAlTiCrN coating resists heat and abrasive wear in hard-material cutting\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle supports efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eVariable index spacing reduces chatter and harmonic vibration during milling\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows plunge entry into workpiece\u003c\/li\u003e\n\u003cli\u003eExtended reach of 4.125 inches accommodates deep-pocket and long-reach applications\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate provides rigidity and edge retention\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and direct-fit solid carbide square end mill for use in standard 0.5-inch end mill holders, collet chucks, and shrink-fit tooling systems on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool clamping torque and runout verification. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Verify holder bore cleanliness and shank seating depth before tightening. Confirm runout with a dial indicator after clamping to avoid premature edge wear or dimensional deviation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches (15.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6 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\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\u003eExtended Reach Length\u003c\/strong\u003e: 4.125 inches\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\u003eCoating\u003c\/strong\u003e: AlTiCrN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\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: 0.07 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: 312230\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733308834098,"sku":"312230","price":230.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ab3f7c5e96ed4725d6d92cc87c7e4b6.jpg?v=1788753974","url":"https:\/\/voomisupply.com\/products\/accupro-312230-square-end-mill-0-5-in-5-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
