It features a 13\/32-inch (0.4063-inch) mill diameter, four flutes, and a 30-degree helix angle that balances chip evacuation with cutting stability. The flutes run in a right-hand spiral with a right-hand cutting direction, and the tool is centercutting, allowing plunge entry into the workpiece. Material grade M42 cobalt construction provides elevated heat resistance compared to standard HSS, making this end mill well-suited for tougher workpiece materials. Machinists and tool-and-die professionals are the primary installers of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits conventional vertical and horizontal milling machines, CNC machining centers, and manual knee mills that accept a 3\/8-inch shank. The 1-inch length of cut (LOC) accommodates shoulder milling, slotting, and contouring at moderate depths. The 2-11\/16-inch overall length (OAL) provides enough clearance for standard work-holding setups without excessive overhang. The bright\/uncoated finish is compatible with cutting fluids and coolant systems typically used in steel and stainless milling operations. No extended-reach geometry is present, keeping the tool rigid for standard-depth applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip flow and reduced cutting force\u003c\/li\u003e\n  \u003cli\u003eFour flutes for a balance of chip clearance and surface finish quality\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute geometry for standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish compatible with a wide range of cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 3\/8-inch shank square end mill for use in collet chucks, end mill holders, and other toolholding systems that accept 3\/8-inch round shanks on milling machines and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists and toolroom professionals. Power down the spindle and confirm the machine is in a locked, de-energized state before changing tooling. Seat the shank fully into the collet or toolholder and tighten to the toolholder manufacturer's specification. Inspect the collet or holder for wear before use, as runout caused by a worn holder will reduce tool life and surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 13\/32 inches (0.4063 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 (LOC)\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 1.0000 to 1.2500 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\u003eOverall Length (OAL)\u003c\/strong\u003e: 2-11\/16 inches (2.6875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\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\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: E2039026\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736112791858,"sku":"E2039026","price":64.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e44e0adfa013592fdf46da2e70c512f3.jpg?v=1788775949","url":"https:\/\/voomisupply.com\/products\/hertel-e2039026-square-end-mill-13-32-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
