It carries a 5\/16-inch cutting diameter with a 1-3\/8-inch length of cut, a 3\/8-inch shank diameter, and a 3-1\/8-inch overall length. The 30-degree spiral flute geometry promotes chip evacuation and balanced cutting forces across a range of ferrous and non-ferrous workpiece materials. This tool ships uncoated and is designed for right-hand cut with right-hand flute direction. Machinists and tool room operators working with manual mills, CNC knee mills, or VMCs are the primary users of this style of end mill.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits long-series applications where standard-reach tooling cannot access the required depth. The 1-3\/8-inch length of cut accommodates slots, pockets, and peripheral milling passes that fall within the 1.25-inch to 1.5-inch cut-depth range. It is well suited to general-purpose milling of low-to-medium alloy steels, tool steels, cast iron, and aluminum in both job shop and maintenance environments. The non-center-cutting geometry means plunge entry is not recommended without a pre-drilled lead hole or ramping strategy.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM7 high speed steel construction provides good toughness and wear resistance for general-purpose milling\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip flow and reduced cutting force\u003c\/li\u003e\n  \u003cli\u003e4-flute design balances material removal rate with chip clearance\u003c\/li\u003e\n  \u003cli\u003eLong-series length of cut (1-3\/8 inches) reaches deeper slots and pockets than stub or standard-length tooling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute configuration suits conventional and climb milling on standard spindles\u003c\/li\u003e\n  \u003cli\u003eUncoated finish allows resharpening without coating concerns\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit end mill for any standard milling machine, machining center, or mill-drill that accepts a 3\/8-inch straight shank tool holder, collet, or end mill adapter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or toolroom technician. The machine spindle must be at a full stop and the drawbar or collet nut fully tightened before any cutting operation begins. Verify runout with a dial indicator after chucking, as excessive runout accelerates edge wear and degrades surface finish. Because this tool is not center-cutting, avoid direct axial plunging into solid material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-3\/8 inches (1.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/8 inches\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\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel, Grade M7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\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\u003eCenter Cutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: E1034020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51728266690866,"sku":"E1034020","price":49.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/288dc9399b4743ac5d02f685dd1cc9cb.jpg?v=1788690156","url":"https:\/\/voomisupply.com\/products\/hertel-e1034020-square-end-mill-5-16-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
