It features a 5\/8-inch mill diameter, a 0.03-inch corner radius, and four right-hand spiral flutes with a high helix angle that promotes efficient chip evacuation and reduced cutting forces. The AlCromax (ALCRO-MAX) PVD coating provides high heat resistance and extended tool life in elevated-temperature applications. Single-end configuration with a straight cylindrical shank makes it compatible with standard toolholders used in CNC machining centers and milling operations. This end mill handles both roughing and finishing passes, making it a practical choice for shops running high-performance materials.\u003c\/p\u003e\n\u003cp\u003eThe TC21521 is suited for professional machining environments where tight tolerances and hard-to-machine materials are common. Its stub-length geometry with a 3\/4-inch length of cut and 3-inch overall length provides rigidity in applications requiring controlled depth and minimal deflection. Typical install scenarios include aerospace, medical, and precision manufacturing where superalloys and stainless steel are primary workpiece materials. The straight cylindrical shank with h6 tolerance fits standard milling toolholders and collet chucks without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and high-temperature alloys\u003c\/li\u003e\n  \u003cli\u003eAlCromax (ALCRO-MAX) PVD coating rated for high-heat cutting in superalloys, Inconel, and titanium alloy\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand spiral design with high helix for efficient chip clearance\u003c\/li\u003e\n  \u003cli\u003e0.03-inch corner radius with tight tolerance of -0.001 to +0.001 inch for consistent edge prep\u003c\/li\u003e\n  \u003cli\u003eStub-length body provides increased rigidity and reduced deflection at depth\u003c\/li\u003e\n  \u003cli\u003eCapable of roughing and finishing in a single tool setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard milling toolholders.

Ensure the toolholder is clean and free of debris before seating the shank; the h6 shank tolerance requires a properly matched collet or holder bore for accurate runout. Follow the machine tool manufacturer torque specifications for drawbar and collet nut tightening. Verify spindle speed, feed rate, and depth of cut against published speeds-and-feeds data for the specific workpiece material before cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 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: 3\/4 inch (2.2500 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 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\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches), Tolerance: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 \/ 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlCromax (ALCRO-MAX), PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Superalloys, Titanium Alloy, Inconel, Stainless Steel, Cast Iron, Alloy Steel, Ferrous Metal\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\u003eChipbreaker\u003c\/strong\u003e: No\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: 0.44 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: TITAN USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TC21521\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TITAN USA","offers":[{"title":"Default Title","offer_id":51741121904946,"sku":"TC21521","price":192.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f178fc2b1d31076b15d5798b72c3c276.jpg?v=1788829461","url":"https:\/\/voomisupply.com\/products\/titan-usa-tc21521-corner-radius-end-mill-5-8-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
