With a 7\/64 inch (0.1094 inch) cutting diameter and four spiral flutes ground at a 30-degree helix angle, this end mill delivers clean, efficient chip evacuation and smooth surface finishes. The TiN (titanium nitride) coating increases surface hardness and extends tool life in abrasive cutting conditions. A 3\/8 inch length of cut and 1\/8 inch shank diameter make it well suited for tight-clearance work. It is installed by machinists and toolroom technicians using CNC machining centers or manual milling machines.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for light-to-medium milling applications where a small-diameter, high-precision tool is required. The centercutting design allows plunge cutting in addition to peripheral and slot milling. Right-hand cut and right-hand flute configuration are standard for conventional CNC and manual mill setups. Typical applications include slot milling, profiling, and contouring in ferrous and non-ferrous materials across job shop, tool-and-die, and maintenance machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eTiN finish improves surface hardness and reduces friction during cutting\u003c\/li\u003e\n\u003cli\u003e4-flute spiral design at 30-degree helix angle for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge entry into workpieces\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — compatible with standard mill spindle rotation\u003c\/li\u003e\n\u003cli\u003e1\/8 inch shank fits standard collets and end mill holders widely available in the trade\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or stock end mill for CNC machining centers and manual milling machines accepting a 1\/8 inch shank collet or end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and the control in an e-stop or tool-change state. Seat the shank fully into the collet or end mill holder and torque the retention mechanism per the toolholder manufacturer's specification. Inspect the cutting edges and coating for chips or wear before mounting. Follow applicable shop safety procedures and machine guarding requirements during setup and operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/64 inch (0.1094 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5000 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: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eWeight\u003c\/strong\u003e: 0.02 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: 750540\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747548856626,"sku":"750540","price":30.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e056c079937a55995fe5b4987ebc62a7.jpg?v=1788882370","url":"https:\/\/voomisupply.com\/products\/hertel-750540-square-end-mill-7-64-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
