Featuring an 8-flute geometry and a 40-degree helix angle, this end mill delivers improved surface finish and chip evacuation during aggressive cuts. The micrograin carbide substrate provides the rigidity and edge retention required for demanding machining operations in CNC milling environments. An AlTiCrN coating adds thermal resistance and reduces tool wear in high-heat cutting conditions. This tool is center-cutting capable, allowing direct plunge entry into the workpiece without pre-drilling.\u003c\/p\u003e\u003cp\u003eThe 317238 is suited for finish milling, slotting, and profiling operations in ferrous materials, hardened steels, and superalloys where heat and wear resistance are critical. Its 8-flute design makes it particularly effective for light-depth, high-feed passes on horizontal or vertical machining centers. The spiral flute configuration and right-hand cut direction are standard for conventional CNC milling setups. This end mill is intended for use by machinists and tool-and-die professionals working with precision CNC equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-flute configuration for improved surface finish and higher feed rates\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip flow and reduced chatter\u003c\/li\u003e\n\u003cli\u003eAlTiCrN coating for thermal resistance and extended tool life in high-heat applications\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate provides superior rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable for direct plunge milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flute direction for standard CNC milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement end mill for CNC vertical and horizontal machining centers accepting a 0.625 inch straight shank.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Verify shank seating depth and runout with an indicator before commencing cuts. Follow applicable shop safety standards when handling carbide tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 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: AlTiCrN\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\u003eCenter Cutting\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\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 pounds\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: 317238\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51735600464178,"sku":"317238","price":214.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8385e42ba3c69a485d98d1aa87cdc7fe.jpg?v=1788773199","url":"https:\/\/voomisupply.com\/products\/accupro-317238-square-end-mill-5-8-in-8-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
