It features a 3\/8 inch cutting diameter, a 1 inch length of cut, and five flutes with a 38-degree right-hand helix angle. The variable index geometry reduces chatter and improves surface finish consistency. A TiAlCN coating provides thermal and wear resistance, extending tool life in ferrous and hardened materials. The shank diameter matches the cutting diameter at 3\/8 inch, and the overall length is 3 inches. This tool is intended for machinists and toolroom professionals working on CNC mills and machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and pocketing operations on steel, stainless steel, cast iron, and similar materials where a high-flute-count, coated carbide tool delivers an advantage. The centercutting capability allows for plunge entry. The right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations. It is a single-end tool packaged individually. Typical applications include production machining, mold work, and precision die cutting in both job-shop and production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/8 inch cutting diameter with matching 3\/8 inch shank for direct collet or end mill holder mounting\u003c\/li\u003e\n\u003cli\u003eFive flutes with variable index spacing to reduce harmonic vibration and improve finish\u003c\/li\u003e\n\u003cli\u003e38-degree right-hand helix angle optimized for chip evacuation and cutting efficiency\u003c\/li\u003e\n\u003cli\u003eTiAlCN coating for elevated heat and abrasion resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge milling entry\u003c\/li\u003e\n\u003cli\u003eSubmicron carbide grade for edge strength and extended tool life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and production tooling option for CNC machining centers and manual mills accepting 3\/8 inch shank end mills in standard collet chucks or end mill holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank to the full recommended engagement depth in the holder and torque the set screw or collet nut per the holder manufacturer specifications. Inspect the tool for chips or edge damage before each use and confirm runout with a dial indicator when precision finishing is required.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 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: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (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\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\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\u003eCoating\u003c\/strong\u003e: TiAlCN\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.22 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3398525\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51730284183858,"sku":"3398525","price":103.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f4db0e48a1997cfe5dd176c66a02da0_876e9e45-25b8-44f2-bb75-9152038e98bd.jpg?v=1788714628","url":"https:\/\/voomisupply.com\/products\/iscar-3398525-square-end-mill-3-8in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
