Built to Series 8200 standards, it features a 3\/4-inch cutting diameter, a 1-1\/2-inch length of cut, and a 4-inch overall length. The variable helix geometry and variable index spacing reduce harmonic vibration during cutting, improving surface finish and tool life. Four flutes provide efficient chip evacuation. The Duarise finish enhances wear resistance. This tool is used by machinists and CNC operators working in job shops, tool rooms, and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials. The straight flute configuration and centercutting capability allow plunge entry as well as lateral passes. The right-hand cut and right-hand flute orientation are standard for conventional CNC machining centers. A 3\/4-inch shank diameter ensures secure tool holding in standard ER or side-lock collet chucks. It is well-matched to full-depth roughing and finishing passes where vibration control is a priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable helix and variable index geometry reduces chatter and vibration during aggressive cuts\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance versus HSS tooling\u003c\/li\u003e\n\u003cli\u003eDuarise finish improves surface hardness and lubricity at the cutting edge\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eFour-flute straight configuration balances chip clearance with cutting contact\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill for use in standard 3\/4-inch tool holders on CNC machining centers and manual mills accepting a 3\/4-inch shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the spindle fully stopped and the machine in a safe, de-energized state. Secure the shank to the specified clamping torque for the tool holder type in use, referencing the tool holder manufacturer guidelines. Inspect the cutting edges and shank for chips or runout before each use. Tool selection and feeds and speeds should be verified against the workpiece material and machine capability before cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Duarise\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\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0012 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 8200\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.2 inches L x 1.15 inches H x 1.05 inches W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.79 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: 82002621\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731106169138,"sku":"82002621","price":549.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d60df0395eed4a048056f879a293aea9_1a507e6a-f99f-48d4-bc07-9d2144a8ca62.jpg?v=1788727033","url":"https:\/\/voomisupply.com\/products\/osg-82002621-square-end-mill-3-4-inch-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
