Built from M42 cobalt high-speed steel with a TiAlN coating, it delivers heat resistance and edge retention under demanding cutting conditions. The 5\/16 inch diameter tool features 3 flutes in a right-hand spiral configuration with a coarse pitch, which breaks chips into smaller segments and reduces cutting forces compared to standard end mills. It carries a 3\/4 inch length of cut and a 2.5 inch overall length. Machinists and tool-and-die professionals use this style of end mill for roughing passes where material removal rate takes priority over surface finish.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing operations in manual mills and CNC machining centers. The coarse-pitch flute geometry handles steels, stainless, and alloy materials where chip clearance and heat buildup are primary concerns. The 3\/8 inch shank diameter seats in standard collets and end mill holders. It is a single-end, non-center-cutting tool, which means it is intended for side milling and peripheral roughing passes rather than plunge cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for elevated heat resistance and toughness\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life in high-temperature cutting environments\u003c\/li\u003e\n\u003cli\u003eCoarse-pitch, 3-flute design promotes chip evacuation and reduces cutting pressure\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flute orientation\u003c\/li\u003e\n\u003cli\u003eNon-center-cutting single end — optimized for peripheral roughing passes\u003c\/li\u003e\n\u003cli\u003e3\/8 inch shank fits standard collets and end mill holders\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 end mill holders and collet chucks accepting a 3\/8 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle at a complete stop and the machine locked out per applicable safety procedures. Seat the 3\/8 inch shank fully in the collet or end mill holder and torque the retention mechanism per the toolholder manufacturer specifications. Because this is a non-center-cutting tool, do not use it for direct plunge entry into solid material. Verify runout with a dial indicator before beginning a roughing pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 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\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\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\u003ePitch\u003c\/strong\u003e: Coarse\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\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: 62852579\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733050818866,"sku":"62852579","price":48.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc02b9c9510ce49dc70bdee5101cdb89.jpg?v=1788750958","url":"https:\/\/voomisupply.com\/products\/hertel-62852579-roughing-end-mill-5-16-in-3-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
