Built from micrograin solid carbide and coated with TiCN, it delivers the hardness and heat resistance required for high-feed roughing passes on ferrous and non-ferrous materials. The chipbreaker geometry reduces cutting forces and chip load, allowing heavier depths of cut without excessive heat buildup. With a 3\/8 inch diameter, 4 flutes, and a 1-1\/8 inch length of cut, this tool is suited for machining centers and CNC mills running right-hand spindle rotation.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in job shop, production, and maintenance machining environments where roughing cycle times need to be reduced before a finishing pass. The 3\/8 inch shank and regular-length geometry make it compatible with standard collet chucks, end mill holders, and shrink-fit tooling with 3\/8 inch bore. Typical applications include slotting, profiling, and peripheral roughing in steel, stainless, cast iron, and hardened materials where TiCN coating provides the necessary wear resistance. A licensed machinist or CNC operator typically selects and installs this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves wear resistance and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eChipbreaker flute geometry reduces cutting forces during aggressive roughing passes\u003c\/li\u003e\n  \u003cli\u003e4 right-hand flutes with right-hand cutting direction for standard spindle setups\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eShank diameter tolerance of +0.0001 to -0.0004 inches ensures consistent tool holding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use roughing end mill for CNC machining centers and manual mills accepting 3\/8 inch straight-shank toolholders including collet chucks, end mill holders, and shrink-fit systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator with the machine spindle fully stopped and locked out per facility lockout\/tagout procedures. Ensure the toolholder bore is clean and free of chips before seating the shank. Torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cutting program to confirm proper seating and avoid premature edge wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 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: 1.125 inches (1-1\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches (3\/8 inches)\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: TiCN\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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: Yes\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: +0.000 to -0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C430L3750-C4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51748589764914,"sku":"C430L3750-C4","price":513.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3bb35bed52b85e6bbf4246f530184f1d.jpg?v=1788895465","url":"https:\/\/voomisupply.com\/products\/hertel-c430l3750-c4-roughing-end-mill-3-8-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
