Built from micrograin solid carbide and coated with titanium nitride (TiN), this tool delivers hardness and heat resistance suited for high-speed roughing passes. The chipbreaker geometry on its 4 flutes breaks chips into smaller segments, reducing cutting forces and heat buildup during deep cuts. With a 3\/8 inch diameter and 5\/8 inch length of cut, it is sized for general-purpose roughing work on milling machines and machining centers. Right-hand cutting and right-hand flute direction are standard. Centercutting capability allows plunge entry without a pre-drilled hole.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use by machinists and toolroom operators running CNC or manual milling equipment. It is well suited for roughing operations on ferrous and non-ferrous metals where chip control is a priority. The regular length shank keeps deflection low in standard tool holders. The 3\/8 inch shank diameter fits common ER collets and end mill holders found in most shop environments. Applications include slotting, profiling, and pocketing where finish quality is secondary to material removal rate.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eChipbreaker flute geometry reduces cutting forces and improves chip evacuation during roughing passes\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction provides rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and extends tool life in metal cutting\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand helix for standard milling machine spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eShank diameter tolerance of +0.0001 to -0.0004 inches ensures consistent tool holder fit\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 compatible with standard 3\/8 inch end mill holders, ER collet chucks, and similar toolholding systems used on CNC and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist familiar with toolholding torque requirements and runout specifications. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Confirm the tool holder bore is clean and free of debris before seating the shank. Do not exceed the manufacturer-recommended depth of cut or feed rate for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.375 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: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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: 0.1 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: 2500506\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728121299250,"sku":"2500506","price":143.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/259f3b04882e836aaab0f175a5849175.jpg?v=1788688347","url":"https:\/\/voomisupply.com\/products\/hertel-2500506-roughing-end-mill-3-8-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
