With a 5\/16 inch cutting diameter, 1-5\/8 inch length of cut, and 4 inch overall length, this end mill delivers consistent material removal in tight tolerances. The 4-flute spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. A titanium nitride (TiN) finish adds surface hardness and wear resistance to the carbide substrate. This tool is installed and operated by machinists and CNC programmers working in job shops, production machining environments, and maintenance facilities.\u003c\/p\u003e\u003cp\u003eThe 750559 is suited for slot milling, peripheral milling, and plunge cutting in a range of workpiece materials. The centercutting geometry allows direct plunge entry without a pre-drilled hole, adding flexibility to tool paths. The right-hand cut, right-hand spiral flute design is compatible with standard CNC machining centers, knee mills, and manual vertical mills. The 5\/16 inch shank diameter fits standard ER collets and end mill holders commonly found in these setups. It is well matched to finishing and semi-finishing passes where dimensional accuracy is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life versus high-speed steel alternatives\u003c\/li\u003e\n\u003cli\u003eTiN coating increases surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003e4-flute spiral design with 30-degree helix angle for efficient chip flow and improved finish quality\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eRight-hand cut geometry compatible with standard spindle rotation on CNC and manual mills\u003c\/li\u003e\n\u003cli\u003eUniform 5\/16 inch shank and cutting diameter simplifies tool holding setup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill for standard ER collet chucks, end mill holders, and milling chucks accepting a 5\/16 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Secure the shank fully into the tool holder to the recommended gauge line depth and torque the collet nut or set screw per the tool holder manufacturer specifications before beginning any cut. Inspect the cutting edges and TiN coating for chips or wear before each use. Do not exceed the tool manufacturer recommended feed and speed parameters for the workpiece material being machined.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 1-5\/8 inches (1.625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 750559\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51745681899826,"sku":"750559","price":51.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/926c3a94d078edf851545727ef4564ee.jpg?v=1788864760","url":"https:\/\/voomisupply.com\/products\/hertel-750559-square-end-mill-5-16-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
