Built on the HS Series platform, it features a 3\/16 inch diameter with a 0.030 inch corner radius and an AlCrTiN coating that resists heat and wear at elevated cutting speeds. With 5 flutes, a variable index, and a 38-degree helix angle, this end mill delivers smooth chip evacuation and reduced chatter. It is centercutting, allowing direct plunge entry, and the extended reach design with a 1\/2 inch reach length makes it suitable for deep-cavity and shoulder milling applications. Right-hand cut and right-hand flute direction are standard configuration.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers handling precision work in tool steel, stainless, and high-temp alloys. The extended reach neck geometry and reduced 0.178 inch neck diameter allow access to tight pockets and stepped features where standard end mills cannot reach. It is a single-end tool intended for production and prototype machining environments where consistent corner geometry and surface finish are required. Machinists and CNC programmers working in aerospace, die-and-mold, and medical component shops will find this geometry particularly applicable.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlCrTiN coating provides thermal resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e5-flute variable index design reduces harmonic chatter and improves finish quality\u003c\/li\u003e\n\u003cli\u003eExtended reach with 0.500 inch reach length and reduced 0.178 inch neck diameter for deep-pocket access\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without pre-drilling\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate offers rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003e0.030 inch corner radius reduces stress concentration and extends corner life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill for use in standard 3\/16 inch collet or end mill holders on CNC machining centers requiring extended-reach tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Secure the shank in a properly sized collet or end mill holder, ensuring full shank engagement to minimize runout. Verify spindle and tool holder are clean and free of debris before seating. Follow machine tool manufacturer guidelines for maximum RPM and feed rate recommendations when using extended-reach tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1875 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: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.178 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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\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\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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: 0.01 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: 312060\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727368388914,"sku":"312060","price":70.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/218a9bb0ec85e0bcef2be0718319066c_40e636ac-2f3b-4b09-9d23-b97af1ca91aa.jpg?v=1788676829","url":"https:\/\/voomisupply.com\/products\/accupro-312060-corner-radius-end-mill-3-16-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
