It features a 1\/16 inch cutting diameter, a 0.01 inch corner radius, and four helical flutes ground from micrograin carbide stock. The WXS PVD coating improves wear resistance and heat dissipation, extending tool life in high-speed finishing and light roughing passes. With a 2.25 inch overall length and extended-reach geometry, this tool suits deep-pocket work and tight-clearance setups where standard-length tools cannot reach. It is a right-hand cut, centercutting, single-end tool from OSG Series 4471.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and milling machines used in job shops, aerospace, medical device manufacturing, and precision tooling environments. The extended reach and small diameter make it particularly well-matched to slotting, profiling, and corner-blending operations in hard materials. Its centercutting capability allows direct plunge entry. The high helix angle promotes efficient chip evacuation in ferrous and exotic alloy workpieces. A straight-cylindrical shank fits standard collet toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention in hard materials\u003c\/li\u003e\n\u003cli\u003eWXS PVD coating for improved wear resistance in steel, stainless steel, and superalloys\u003c\/li\u003e\n\u003cli\u003e0.01 inch corner radius reduces stress concentration and extends part and tool life\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003eExtended reach with 1\/4 inch reach length and 0.058 inch neck diameter for deep-pocket access\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, high helix, helical flute geometry promotes clean chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard collet-style toolholders accepting a 1\/8 inch straight-cylindrical shank. Primary workpiece materials are steel, stainless steel, cast iron, superalloys, titanium, and hard materials per OSG Series 4471 application data.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the toolholder collet bore matches the 1\/8 inch shank diameter and that runout is minimized before cutting. Power down and lock out the spindle before inserting or removing the tool. Do not exceed the tool's rated depth of cut or length of cut; the 0.4375 inch length of cut dimension defines the usable flute zone.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.01 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.058 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1\/4 inch (0.25 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: WXS (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 to -0.0008 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 4471\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.4 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 447100111\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51746560934194,"sku":"447100111","price":134.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a195512e5c26195f94f8fe84438c1c1f.jpg?v=1788871321","url":"https:\/\/voomisupply.com\/products\/osg-447100111-corner-radius-end-mill-1-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
