Built from M7 high speed steel and left uncoated, this tool delivers consistent cutting performance without the added cost of a coating. It runs a 3\/8 inch cutting diameter with a 3\/4 inch length of cut, a 30-degree helix angle, and a right-hand cut with right-hand spiral flutes. The centercutting geometry allows direct plunge entry into the workpiece. Machinists and tool and die professionals working on CNC mills, manual knee mills, or bridgeport-style machines will find this a dependable choice for slotting, profiling, and step milling.\u003c\/p\u003e\u003cp\u003eThis end mill suits light to moderate material removal in shop and production environments. The 3-flute configuration balances chip evacuation and surface finish, making it effective on aluminum, mild steel, and similar machinable alloys. The double-end design extends tool life by providing a second cutting end once the first is worn. At 3-1\/2 inches overall length with a 3\/8 inch shank diameter, it fits standard ER and straight-bore collet systems commonly found in vertical machining centers and manual mills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high speed steel construction for toughness and wear resistance in general-purpose milling\u003c\/li\u003e\n\u003cli\u003eDouble-end design doubles usable tool life per unit\u003c\/li\u003e\n\u003cli\u003e3-flute spiral flute geometry improves chip flow and finish quality\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle supports smooth cutting action and reduced chatter\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eUncoated finish suits applications where coating is not required or where regrinding is anticipated\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard OEM-style replacement or direct-use end mill for vertical milling machines and CNC machining centers that accept 3\/8 inch straight shank tooling in ER collets or straight-bore holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or tool holder and torque the retention nut to the tool holder specification. Confirm runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear and degrades surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\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\u003eLength of Cut Range\u003c\/strong\u003e: 0.7000 - 0.8000 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: 3-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble End\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: E1052024\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735020536114,"sku":"E1052024","price":63.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/233a8b453277093de608b94a27d2593a.jpg?v=1788769296","url":"https:\/\/voomisupply.com\/products\/hertel-e1052024-square-end-mill-3-8-in-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
