Built from M42 cobalt high-speed steel with a TiCN coating, this end mill delivers elevated heat and wear resistance compared to standard HSS tooling. The 3\/16 inch cutting diameter and 4-flute configuration with a fine pitch provide efficient chip evacuation and smooth cutting action on ferrous and non-ferrous materials. With a right-hand cutting and right-hand flute direction, it suits standard CNC and manual milling setups. Installation and use require no center cutting entry — plunge cuts are not supported with this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for roughing passes in job shop, production, and toolroom environments. It fits applications where a reduced-diameter, short-length-of-cut tool is needed for profiling, slotting, or peripheral roughing in confined areas or on smaller workpieces. The 3\/8 inch shank diameter allows compatibility with standard milling chucks, collets, and end mill holders commonly found in both manual and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for improved red hardness and tool life over standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating provides additional surface hardness and lubricity for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003eFine pitch, 4-flute design optimized for smooth roughing cuts and efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with a 3\/8 inch shank for secure chuck or collet retention\u003c\/li\u003e\n  \u003cli\u003eNon-centercutting — suited for peripheral and slot milling entries only\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard roughing end mill replacement for use with 3\/8 inch collets, end mill holders, or milling chucks on CNC machining centers and manual knee mills requiring a 3\/16 inch cutting diameter tool.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 3\/8 inch shank fully into the holder and torque the retention mechanism per the holder manufacturer's specification. Confirm runout with a dial indicator before beginning a cut, and note that this tool is not centercutting — do not use for direct plunge entry into solid 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\/16 inch (0.188 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.00394 to -0.00197 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.66 x 0.59 x 0.51 inches\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\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: 44838605\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747554263346,"sku":"44838605","price":53.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/445776dfc11c982d122c922172d083f7.jpg?v=1788882459","url":"https:\/\/voomisupply.com\/products\/hertel-44838605-roughing-end-mill-3-16-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
