It features a 3\/8 inch cutting diameter, a 0.0200 inch corner radius, and five flutes configured in a right-hand spiral with a 45-degree high helix angle. The AlTiN PVD coating provides thermal resistance and extended tool life when cutting steel, stainless steel, superalloys, titanium, and hard materials. At 2 inches overall length with a 1\/2 inch length of cut, this is a stub-length geometry designed for rigidity and reduced deflection in tight clearance situations. It is centercutting, allowing plunge entry, and accepts standard straight-cylindrical toolholders with a 3\/8 inch shank.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finish milling operations on ferrous and hard materials in CNC machining centers. The corner radius geometry reduces stress concentration at the cutting edge, improving edge life compared to a sharp-corner tool. It is appropriate for profiling, contouring, and slot finishing in steel alloys, stainless grades, nickel-based superalloys, titanium, and hardened materials. The normal pitch and fixed helix design provide predictable chip evacuation in finishing cuts with light radial engagement. It is used by CNC machinists and tool-and-die professionals in production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance in hard and exotic alloys\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating rated for steel, stainless steel, superalloys, titanium, and hard material applications\u003c\/li\u003e\n\u003cli\u003e0.0200 inch corner radius reduces edge chipping and improves surface finish on profiled walls\u003c\/li\u003e\n\u003cli\u003eFive-flute, right-hand spiral geometry optimized for finishing passes with light chip loads\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge entry without a pre-drilled start hole\u003c\/li\u003e\n\u003cli\u003eStub-length profile increases radial stiffness and minimizes deflection in close-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-cylindrical toolholders accepting a 3\/8 inch shank diameter.

Before changing tooling, confirm the spindle is at a complete stop and the machine is in a safe state per shop lockout procedures. Seat the shank fully in the toolholder to the recommended gauge-line depth and torque the retention mechanism per the toolholder manufacturer's specification. Verify runout against the stated TIR maximum of 0.0005 inch before running production cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches (2.0000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0200 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees (High)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\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 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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel; Stainless Steel; Superalloys and Titanium; Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.00100 to -0.00100 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 \/ 0.0000 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.0600 \/ +0.0600 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: S545R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17007004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557783634226,"sku":"17007004","price":120.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bdfd18e2e84f998028308168b3c643a8_94001f91-d7d7-46fb-9f50-d4dc58a13c40.jpg?v=1786395123","url":"https:\/\/voomisupply.com\/products\/seco-17007004-corner-radius-end-mill-3-8-in-5-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
