With a 5\/16 inch (0.3125 inch) mill diameter, 1\/2 inch length of cut, and a 0.03 inch corner radius, this tool delivers both roughing and finishing capability in a single-end, stub-length configuration. The 4-flute, right-hand helical design runs at a medium helix angle and is finished with an AlTiN (aluminum titanium nitride) PVD coating for heat resistance and extended tool life in abrasive and high-temperature materials. Shank diameter matches the mill diameter at 5\/16 inch with an h6 tolerance, ensuring secure toolholder engagement.\u003c\/p\u003e\u003cp\u003eThe TC73930 is suited for machining superalloys, titanium alloys, Inconel, stainless steel, alloy steel, cast iron, and other ferrous metals. Its stub-length geometry provides rigidity in tight setups, making it a practical choice for milling operations on CNC machining centers where minimizing deflection in hard-to-machine materials is critical. The centercutting designation in the raw data is noted as no in the attribute specs, so this tool is intended for peripheral and side milling rather than plunge cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and high-temperature alloys\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating provides thermal protection when cutting stainless steel, titanium, and Inconel\u003c\/li\u003e\n\u003cli\u003e0.03 inch corner radius reduces stress concentration and improves edge strength at the tool tip\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand helical design supports both roughing and finishing passes\u003c\/li\u003e\n\u003cli\u003eStub-length body maximizes stiffness and minimizes chatter in short-reach setups\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank with h6 tolerance for precise toolholder fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-bore toolholders accepting a 5\/16 inch shank diameter.

Ensure the toolholder bore is clean and free of debris before seating the shank, and torque set screws or collet nuts to the toolholder manufacturer specifications. Confirm runout with a dial indicator before beginning a cut, particularly when working with hard materials where tool deflection can cause premature edge wear. Do not use this tool for plunge entry given its non-centercutting geometry.\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\u003eShank 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\/2 inches (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.0010 to 0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 to 0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Superalloys, Titanium, Stainless Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TITAN USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TC73930\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51747535552818,"sku":"TC73930","price":56.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd47e8aa7038d40d36ccb972eb4125a1_c93ad66d-b6aa-46a8-b472-7234115e6b2d.jpg?v=1788882085","url":"https:\/\/voomisupply.com\/products\/titan-usa-tc73930-corner-radius-end-mill-5-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
