It carries a 0.25 inch cutting diameter, a 1.25 inch length of cut, and a 0.375 inch straight shank, with an overall length of 3.0625 inches. The 30-degree spiral flute geometry promotes efficient chip evacuation during milling operations. Designated as a long-length tool, it provides additional reach for deeper pockets and slots compared to standard-length equivalents. This end mill is uncoated and suited for general-purpose milling in ferrous and non-ferrous materials. It is installed and operated by machinists and tool-and-die professionals working with manual or CNC milling machines.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for slotting, profiling, and peripheral milling applications in job shop, production, and maintenance machining environments. The long-length classification makes it appropriate for deep-pocket work where a standard-length tool lacks sufficient reach. Right-hand cut and right-hand flute geometry suit the vast majority of conventional vertical and horizontal milling setups. Because this tool is not center-cutting, it is not suited for direct plunge entry and requires a pre-drilled hole or ramping entry path when beginning a slot.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM7 high speed steel construction for toughness across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e4-flute configuration balances chip capacity with surface finish quality\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle on spiral flutes for smooth cutting action and chip evacuation\u003c\/li\u003e\n  \u003cli\u003eLong-length designation provides 1.25 inches of length of cut for deeper pocket access\u003c\/li\u003e\n  \u003cli\u003eUncoated finish allows straightforward regrinding and reconditioning\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute orientation for standard milling machine compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct substitute for 0.25 inch diameter, 4-flute, long-length square end mills with a 0.375 inch shank used in standard milling machine collets and tool holders.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist using an appropriate collet, end mill holder, or Weldon-style side-lock holder sized for a 0.375 inch shank. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the tool. Secure the shank to the full recommended engagement depth of the holder to prevent pullout under cutting loads. Because this tool is not center-cutting, do not program a direct axial plunge 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: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches (1-1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0625 inches (3-1\/16 inch)\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\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\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: 0.15 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: E1034016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736369234226,"sku":"E1034016","price":49.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7710635a7df3f60970bf7ab9d9a03a91.jpg?v=1788777519","url":"https:\/\/voomisupply.com\/products\/hertel-e1034016-square-end-mill-1-4-in-4-flute-hss-long","provider":"Voomi Supply","version":"1.0","type":"link"}
