It measures 5\/16 inch in cutting diameter with a 2 inch length of cut, a 3\/8 inch shank diameter, and a 3-3\/4 inch overall length, placing it in the extra-long category for reach into deeper cavities and pockets. The tool is manufactured from M7 high speed steel in an uncoated finish and features a 30-degree helix angle with right-hand cut and right-hand spiral fluting. Machinists and CNC operators install this tool in standard end mill holders or collet chucks on vertical mills and machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling applications where extended reach is required. Its extra-long length of cut makes it a practical choice for deep-pocket work, stepped features, and contour milling where a standard-length tool would not reach the full depth. The single-end, non-centercutting geometry means it is intended for side-milling and peripheral passes rather than direct plunge entry. It is appropriate for use on job shop mills, knee mills, and CNC machining centers handling steel, cast iron, aluminum, and similar workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-flute spiral design provides good surface finish and chip evacuation in side-milling operations\u003c\/li\u003e\n\u003cli\u003eM7 high speed steel construction offers toughness and wear resistance for general machining\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting efficiency with tool rigidity\u003c\/li\u003e\n\u003cli\u003eExtra-long 2 inch length of cut enables deep-pocket and extended-reach milling\u003c\/li\u003e\n\u003cli\u003e3\/8 inch shank diameter fits standard collet sizes commonly available on knee mills and machining centers\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use with cutting fluids on a wide range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/8 inch collet chucks and end mill holders on vertical milling machines and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out. Verify collet and holder runout before tightening to minimize premature tool wear. Consult the machine tool manufacturer's guidelines for recommended speeds and feeds for the specific workpiece material. This tool is non-centercutting and should not be used for direct plunge entry without a pre-drilled pilot hole or a ramping toolpath.\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\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/4 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: 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\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\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 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: E1036020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739104149810,"sku":"E1036020","price":61.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a22c3c9e13e10d5e85626e6ddc73dd6.jpg?v=1788809454","url":"https:\/\/voomisupply.com\/products\/hertel-e1036020-square-end-mill-5-16-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
