The tool measures 3\/8 inches in cutting diameter with a 1 inch length of cut, a 3\/8 inch shank diameter, and a 3 inch overall length. It features four flutes with a 38-degree helix angle and a variable index design that reduces harmonic vibration during aggressive cuts. The submicron carbide grade provides edge integrity at elevated cutting speeds. A TiAlCN coating improves heat resistance and extends tool life in ferrous and hardened materials. This end mill is a single-end tool with right-hand cutting and right-hand flute direction.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling in CNC machining centers and manual mills. It is used in job shops and production environments machining steel, stainless steel, cast iron, and similar ferrous alloys. The centercutting capability allows plunge entry directly into the workpiece. The 38-degree helix and variable index geometry make it effective for applications where chatter control and surface finish are priorities. Machinists and CNC operators working in tight-tolerance environments are the primary installers and users of this tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8 inch cutting diameter with 1 inch length of cut for controlled radial engagement\u003c\/li\u003e\n\u003cli\u003eFour-flute spiral design with 38-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic vibration and chatter\u003c\/li\u003e\n\u003cli\u003eTiAlCN coating provides thermal resistance and wear protection in ferrous materials\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eSubmicron solid carbide grade maintains edge sharpness at high feed rates\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill suitable for use in standard 3\/8 inch collet, end mill holder, or shrink-fit tooling systems on CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by machinists and CNC operators using a compatible 3\/8 inch toolholder, collet, or shrink-fit system. Ensure the machine spindle is fully stopped and power is isolated before changing tooling. Verify runout with a dial indicator after seating to confirm proper holder engagement. Follow the toolholder manufacturer torque guidelines when tightening set screws or collet nuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eEnd Type\u003c\/strong\u003e: Single End\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\u003eVariable Helix\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3401272\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51732880425266,"sku":"3401272","price":87.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ba32a6c345bc1a81625bb9fb60cc37b_cc871de6-5196-4bf0-ab19-97c45c77db42.jpg?v=1788747901","url":"https:\/\/voomisupply.com\/products\/iscar-3401272-square-end-mill-3-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
