It features a 3\/4 inch diameter, a 1 inch length of cut, and a 6 inch overall length, making it well suited for extended reach applications. The 5-flute, right-hand spiral configuration runs with a variable index for improved vibration damping and surface finish. An AlCrTiN coating provides heat and wear resistance during high-speed cutting operations. The 0.030 inch corner radius reduces stress concentration at the cutting edge. Centercutting geometry allows plunge milling as part of a toolpath. Material grade is micrograin carbide for edge stability and consistency.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and milling machines where extended reach into deep pockets or cavities is required. The 3-3\/8 inch reach length and reduced neck diameter of 0.712 inches allow access past part features without tool holder interference. Typical applications include die and mold work, aerospace component machining, and precision part manufacturing where corner radius geometry is specified for stress relief or part design requirements. Single-end configuration keeps the tool compact and straightforward to preset.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4 inch mill diameter with 0.030 inch corner radius for edge strength and reduced stress risers\u003c\/li\u003e\n\u003cli\u003e5-flute, right-hand spiral with variable index for chatter reduction and improved finish\u003c\/li\u003e\n\u003cli\u003eAlCrTiN coating for high-temperature wear resistance in ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide substrate for consistent edge integrity and rigidity\u003c\/li\u003e\n\u003cli\u003eExtended reach design: 3-3\/8 inch reach length with 0.712 inch neck diameter\u003c\/li\u003e\n\u003cli\u003eCentercutting capable — supports plunge entry and full toolpath flexibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide corner radius end mill for CNC milling applications requiring a 3\/4 inch shank and extended reach geometry in the HS series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Secure the 3\/4 inch shank in a compatible end mill holder or collet chuck, ensuring proper engagement depth per holder manufacturer specifications. Verify runout at the cutting edge before beginning a production run. Follow machine tool manufacturer guidelines and applicable shop safety procedures 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: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (25.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches (152.4 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.712 inches (0.71 mm nominal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 3-3\/8 inches (3.3750 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.030 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: AlCrTiN\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\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\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: +0.000000 \/ -0.001000 inches\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: 1 pound\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: 312357\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733664104754,"sku":"312357","price":446.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/218a9bb0ec85e0bcef2be0718319066c_2a28a9bb-0c1b-47e2-a5ea-a27b5bab4e31.jpg?v=1788757734","url":"https:\/\/voomisupply.com\/products\/accupro-312357-corner-radius-end-mill-3-4-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
