Manufactured from M7 high speed steel, it delivers reliable edge retention across a range of cutting conditions without a coating. The cutter measures 7\/8 inch in diameter with a 3-1\/2 inch length of cut, placing it in the long-series category. Four spiral flutes at a 30-degree helix angle promote efficient chip evacuation. The right-hand cut and right-hand flute configuration suit standard vertical and horizontal milling machine spindles. Licensed machinists and toolroom personnel are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is suited to slotting, peripheral milling, and profiling operations on knee mills, CNC machining centers, and manual milling machines. The long length of cut — 3-1\/2 inches — makes it appropriate for deep-pocket work and tall-wall profiling where a standard-length end mill would not reach. The non-centercutting design means it is not intended for direct plunge entry into solid material; ramp or helical entry should be used. The 7\/8 inch shank diameter accepts standard R8, CAT, BT, and direct-collet toolholding systems sized for 7\/8 inch shanks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM7 high speed steel construction for toughness in interrupted cuts and general-purpose milling\u003c\/li\u003e\n\u003cli\u003e4 spiral flutes with 30-degree helix angle for balanced chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003eLong-series length of cut at 3-1\/2 inches for deep-pocket and tall-wall applications\u003c\/li\u003e\n\u003cli\u003eUncoated finish — suitable for re-sharpening and regrinding in-house\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — compatible with standard milling spindle rotation\u003c\/li\u003e\n\u003cli\u003eNon-centercutting geometry — requires ramp or helical entry, not direct plunge\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use tooling option for milling machines accepting a 7\/8 inch shank diameter in standard R8, collet, or modular toolholding systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolroom technician. Power down and lock out the machine spindle before inserting or removing the end mill from the toolholder. Ensure the shank is fully seated and the collet or set-screw holder is properly torqued per the toolholder manufacturer's specification. Inspect the cutting edges for chips or wear before each use, as a damaged edge on a non-centercutting tool can cause deflection or workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/8 inch (0.8750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3-1\/2 inches (3.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/8 inch (0.8750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-3\/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\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long Series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.8 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: E1034056\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727189279026,"sku":"E1034056","price":100.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8011ee64891c627f26c6482adcd9ff0.jpg?v=1788674507","url":"https:\/\/voomisupply.com\/products\/hertel-e1034056-square-end-mill-7-8-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
