It features a 5\/32-inch (0.1563-inch) cutting diameter with a 9\/16-inch (0.5625-inch) length of cut, making it well suited for slotting, profiling, and contouring in tight workpiece geometries. The 4-flute spiral design with a 30-degree helix angle promotes efficient chip evacuation and a smooth surface finish. A titanium nitride (TiN) coating adds surface hardness and extends tool life in ferrous and non-ferrous materials. Licensed machinists and CNC operators install this tool in standard end mill holders or collet chucks on vertical and horizontal machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in production machining environments where small-diameter precision cutting is required. The centercutting geometry allows the tool to plunge directly into the workpiece, enabling ramping and pocket-milling operations without a pre-drilled entry point. The 3\/16-inch shank diameter and 2-inch overall length make it compatible with standard toolholding systems on benchtop and full-size CNC mills. Right-hand cut and right-hand flute orientation are standard for conventional and climb milling passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003eTiN finish increases surface hardness and reduces tool wear\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry with 30-degree helix angle for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation for standard milling setups\u003c\/li\u003e\n\u003cli\u003eNo chipbreaker or variable helix — consistent geometry for smooth, predictable cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard small-diameter square end mill for use in CNC machining centers and manual mills equipped with collet chucks or end mill holders accepting a 3\/16-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC operators. Power down and lock out the spindle before inserting or removing the tool from the holder. Ensure the shank is fully seated and the collet or set screw is torqued to the toolholder manufacturer specification. Inspect the cutting edges for chips or wear before each use, as solid carbide tools can fracture if run with damaged geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/32 inch (0.1563 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/16 inch (0.5625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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\u003eFinish\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\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\u003eFlute 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\u003eVariable Helix\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: 0.03 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: 750311\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731048399154,"sku":"750311","price":31.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2dba0aff83f8542af55d3de879bc3e7c.jpg?v=1788726267","url":"https:\/\/voomisupply.com\/products\/hertel-750311-square-end-mill-5-32-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
