Built from M42 cobalt high-speed steel and finished with a TiAlN coating, it handles tough ferrous and stainless materials while resisting heat buildup at the cutting edge. The fine-pitch, 4-flute spiral geometry with right-hand cutting and right-hand flute direction delivers smooth chip evacuation in slotting and peripheral milling operations. At 3\/16 inch in diameter with a 3\/8 inch shank and 1\/2 inch length of cut, this tool is suited for light profiling and roughing passes in confined features. Machinists and tool-and-die professionals will recognize the value of the TiAlN coating for extended tool life in dry or semi-dry cutting conditions.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in manual mills and CNC machining centers where roughing passes require controlled chip load and heat resistance. The non-centercutting design means it is not suited for plunge milling; it is optimized for ramping entries or side milling. The 2-3\/8 inch overall length keeps the tool rigid in short-reach setups, minimizing deflection during heavy passes on hardened or work-hardening materials such as stainless steel and tool steel alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for elevated heat and wear resistance versus standard HSS\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life in dry and semi-dry high-temperature cutting\u003c\/li\u003e\n\u003cli\u003eFine-pitch, 4-flute spiral geometry for efficient chip evacuation in roughing passes\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eNon-centercutting design requires ramp or helical entry — not for direct plunge\u003c\/li\u003e\n\u003cli\u003e3\/8 inch shank diameter fits standard ER and straight-bore toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style roughing end mill for use in standard milling machines and CNC machining centers accepting a 3\/8 inch straight shank toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following standard toolholding procedures. Confirm the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool. Seat the shank fully in the collet or toolholder and torque the retention hardware per the toolholder manufacturer specification. Because this tool is non-centercutting, program ramp or helical entry paths — direct plunge moves will damage the cutting edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal)\u003c\/strong\u003e: 0.1875 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\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\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: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 62914023\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728370532658,"sku":"62914023","price":61.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c4d337705b92a468705bcd672e59dcc0_dd602c06-13e3-46d2-9e2d-b0f34da934c9.jpg?v=1788690730","url":"https:\/\/voomisupply.com\/products\/hertel-62914023-roughing-end-mill-3-16-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
