Ground from micrograin solid carbide, this tool delivers hardness and wear resistance well beyond high-speed steel alternatives. The 0.5-inch cutting diameter pairs with a 2-inch length of cut, giving machinists reach into deep pockets and complex profiles without sacrificing rigidity. A ZrN (zirconium nitride) coating reduces friction and extends tool life across a range of ferrous and non-ferrous workpiece materials. Installed in CNC machining centers and manual mills alike, this end mill is the go-to choice for tool-and-die, mold, and general precision machining work.\u003c\/p\u003e\u003cp\u003eThis end mill suits residential shop and industrial production environments where tight tolerances and smooth surface finishes are required. The 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces, making it well-suited for ramping, helical interpolation, and finish passes on contoured surfaces. The 0.5-inch shank diameter fits standard ER collet chucks, end mill holders, and shrink-fit tooling systems common in CNC setups. With a 4-inch overall length classified as a long-reach geometry, it handles deep-cavity work where standard-length tools cannot reach.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and extended edge life\u003c\/li\u003e\n\u003cli\u003eZrN coating reduces built-up edge and improves lubricity across multiple material types\u003c\/li\u003e\n\u003cli\u003e45-degree right-hand spiral helix for aggressive chip evacuation\u003c\/li\u003e\n\u003cli\u003e2-inch length of cut supports deep pocket and mold cavity profiling\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 0.5-inch shank for direct fit in standard toolholders\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000\/-0.002 inches for consistent fit and finish results\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit cutting tool for CNC machining centers and manual knee mills accepting a 0.5-inch shank diameter end mill holder or collet chuck.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Always power down and lock out the spindle before loading or removing tooling. Ensure the shank is fully seated to the minimum insertion depth recommended by the toolholder manufacturer and that all collet or set-screw clamping interfaces are clean and free of chips before tightening. Verify runout with a dial indicator after installation before initiating a cutting program.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCoating\/Finish\u003c\/strong\u003e: ZrN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 313674\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730797986098,"sku":"313674","price":194.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/12eba5e1e31b4bece3c2c0e8db2189e3.jpg?v=1788723029","url":"https:\/\/voomisupply.com\/products\/accupro-313674-ball-end-mill-0-5-in-2-flute-solid-carbide-zrn","provider":"Voomi Supply","version":"1.0","type":"link"}
