Built from M42 cobalt high-speed steel and coated with TiAlN, it handles heat and wear better than standard HSS tooling. The 3\/16 inch cutting diameter and coarse-pitch spiral flute geometry break chips efficiently, reducing load on the spindle and workpiece. With four flutes and a right-hand cutting and flute direction, this mill is suited for conventional and climb milling on ferrous and non-ferrous materials. It is a practical choice for tool rooms, job shops, and production environments where controlled stock removal is the priority.\u003c\/p\u003e\u003cp\u003eThis end mill is used in vertical and horizontal milling machines, CNC machining centers, and manual mills. Its 3\/8 inch shank diameter fits standard collets and end mill holders. The 1\/2 inch length of cut and 2-3\/8 inch overall length make it appropriate for shallow-to-medium-depth roughing passes in tight setups. The center-cutting design allows plunge entry where needed. Machinists and tool-and-die professionals working on steel, stainless, and similar materials will find the TiAlN coating particularly useful for extending tool life at higher surface speeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003eCoarse-pitch spiral flute design promotes aggressive chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable — supports direct plunge entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003e3\/8 inch shank fits common collets and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for milling machines and machining centers that accept a 3\/8 inch shank end mill holder or collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before seating or removing the tool from the holder. Ensure the shank is fully engaged in the collet or holder to the recommended grip depth and that the holder is properly torqued per the toolholder manufacturer specifications. Inspect the TiAlN coating and cutting edges before use — do not run a chipped or damaged end mill.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 3\/16 inches\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)\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: Coarse\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\u003eOverall Length (OAL)\u003c\/strong\u003e: 2-3\/8 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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eCenter Cutting\u003c\/strong\u003e: Yes\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: 62888458\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730320818482,"sku":"62888458","price":61.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c4c1ab8aa0f6c54c8c5276797a8a4ca_2c773b95-12a2-4a52-8970-621b417b9fdc.jpg?v=1788715338","url":"https:\/\/voomisupply.com\/products\/hertel-62888458-roughing-end-mill-3-16-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
