Built from M7 high speed steel with a titanium nitride (TiN) coating, this tool offers improved surface hardness and wear resistance over uncoated HSS. The 3\/4-inch cutting diameter pairs with a 1\/2-inch shank, and the 30-degree helix angle promotes efficient chip evacuation during peripheral and slot milling. Right-hand cut and right-hand flute direction are standard. Overall length is 3.625 inches, keeping the tool rigid in standard milling setups. Machinists and toolroom operators working on knee mills, CNC machining centers, or manual bridgeports will find this a practical general-purpose end mill.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for light to medium material removal in job shop, maintenance, and production environments. The regular-length geometry and 1-5\/8-inch length of cut make it appropriate for slotting, profiling, and peripheral milling passes at standard depths. The non-center-cutting design means it is not intended for direct plunging; ramp-in or helical entry is recommended when full-slot entry is required. It is packaged individually and sold in single-unit quantities, making it a practical option for low-volume tooling requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM7 high speed steel construction with TiN coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003e4 spiral flutes with 30-degree helix angle for efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction\u003c\/li\u003e\n  \u003cli\u003eNon-center-cutting geometry — ramp or helical entry required for plunge operations\u003c\/li\u003e\n  \u003cli\u003eRegular length design provides rigidity for standard milling depths\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch shank diameter compatible with standard collets and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-shank replacement end mill for use in any milling machine or machining center equipped with a 1\/2-inch collet or end mill holder accepting a 3\/4-inch diameter cutter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 1\/2-inch shank fully in the collet or holder before torquing to the tool holder manufacturer's specification. Confirm runout with a dial indicator before beginning a cut, as excessive runout accelerates wear and reduces surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.750 inches (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\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches (1-5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.500 inches (1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.625 inches (3-5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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: TiN (Titanium Nitride)\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: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: E8031908\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727393128754,"sku":"E8031908","price":80.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772f5217ccb8fbc5aaf06d94022e0ea0.jpg?v=1788677246","url":"https:\/\/voomisupply.com\/products\/hertel-e8031908-square-end-mill-3-4-in-4-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
