Built from M42 cobalt high-speed steel with a 30-degree helix angle, it delivers strong heat and wear resistance during demanding cuts. The 1-inch mill diameter and 2-inch length of cut provide substantial material removal capability, while the TiCN coating reduces friction and extends tool life. Four right-hand spiral flutes with right-hand cutting direction ensure efficient chip evacuation. Machinists and tool-and-die professionals use this end mill on vertical mills, CNC machining centers, and manual knee mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits precision metalworking operations in job shops, tool rooms, and production environments. The cobalt M42 substrate handles harder workpiece materials better than standard M2 HSS, making it appropriate for alloy steels, stainless steel, and similar tough materials. With a 1-inch shank diameter matching the mill diameter, it seats securely in standard end mill holders and collet chucks sized for 1-inch shanks. The 4.5-inch overall length fits most standard spindle setups without requiring extended-reach toolholding.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-inch ball-nose diameter for contour milling and 3D profiling\u003c\/li\u003e\n  \u003cli\u003eM42 cobalt construction for improved hot hardness over standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and increases surface wear resistance\u003c\/li\u003e\n  \u003cli\u003e4 right-hand spiral flutes with 30-degree helix for efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with 1-inch shank diameter for rigid toolholding\u003c\/li\u003e\n  \u003cli\u003eRegular length geometry suited to standard depth-of-cut applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard end mill holders and collet chucks accepting a 1-inch shank diameter on vertical machining centers, CNC mills, and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully into the holder and torque the set screw or collet nut per the toolholder manufacturer specifications. Confirm runout with a dial indicator before beginning the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.7 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: E7020064\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728665837874,"sku":"E7020064","price":191.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a9483be9dd605663dfadfb0b2c5cff9.jpg?v=1788694612","url":"https:\/\/voomisupply.com\/products\/hertel-e7020064-ball-end-mill-1-in-4-flute-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
