Built to Series 8205 standards, it features a 0.6299 inch (16 mm) cutting diameter with a matching 0.6299 inch shank diameter, and runs four flutes with a variable helix and variable index geometry that reduces chatter and improves surface finish. The Duarise coating adds wear resistance and thermal stability. This is a centercutting tool, meaning it can plunge directly into a workpiece. It is installed and operated by machinists and CNC programmers in job shop, production, and tool-and-die environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for general-purpose milling applications including profiling, slotting, and peripheral cuts. With a 32 mm length of cut and 100 mm overall length, it fits standard toolholding setups on vertical machining centers and CNC mills. The straight flute design and micrograin carbide substrate make it a reliable choice for both roughing and finishing passes where dimensional accuracy is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable helix and variable index geometry reduce harmonics and chatter during cutting\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eDuarise coating provides enhanced wear resistance and heat dissipation\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers consistent edge retention\u003c\/li\u003e\n\u003cli\u003eRight hand cut, right hand flute configuration for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eMatched shank and cutting diameter at 0.6299 inches simplifies toolholder selection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill in the OSG Series 8205 line, suited for use in standard 0.6299 inch diameter toolholders on CNC machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before inserting or removing the tool from the holder. Verify runout with a dial indicator after mounting, and confirm toolholder bore cleanliness before clamping. Do not exceed the tool manufacturer-recommended depths of cut or feed rates for the target material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.6299 inches (16 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.6299 inches (16 mm)\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: 32 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 100 mm\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: Duarise\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: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.00 \/ -0.02 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 8205\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.1 x 1 x 0.95 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.57 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8555960\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51744633520434,"sku":"8555960","price":287.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/707f69980717c7412d824ee865014383_3c346bf7-f754-41f3-b203-f0ee9179ee5e.jpg?v=1788859258","url":"https:\/\/voomisupply.com\/products\/osg-8555960-square-end-mill-0-6299-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
