The cutter measures 3\/8 inch in diameter with a 3\/8-inch length of cut and a 0.0200-inch corner radius that reduces chipping at the cutting edge and extends tool life in high-stress applications. A 4-flute, single-end configuration with a variable helix and right-hand cutting direction supports both roughing and finishing operations. The AlTiN PVD coating provides thermal resistance and hardness at elevated cutting temperatures. Series STR440.2 tooling is installed by machinists and tool-and-die professionals on CNC milling equipment.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for shops running stainless steel, titanium, nickel superalloys, and other hard or abrasion-resistant workpiece materials. The stub length type and 2-inch overall length make it well-matched for short-reach applications where rigidity is a priority. The Weldon flat shank seats securely in compatible side-lock toolholders, reducing pullout risk during aggressive passes. Centercutting capability allows plunge entry, expanding the range of operations this tool can handle in a single setup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0200-inch corner radius reduces edge chipping and improves surface finish on hard materials\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating delivers heat and wear resistance for stainless steel and superalloy cutting\u003c\/li\u003e\n\u003cli\u003eVariable helix design reduces harmonics and chatter during milling passes\u003c\/li\u003e\n\u003cli\u003e4-flute, centercutting geometry supports both roughing and finishing in one tool\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank provides positive retention in side-lock toolholders\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for dimensional stability and edge retention\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard side-lock and Weldon flat toolholders accepting a 3\/8-inch shank.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the Weldon flat fully against the toolholder setscrew and torque to the toolholder specification before use. Verify runout against the TIR maximum of 0.0005 inch after installation to confirm proper seating.\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\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees (high, variable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Stainless Steel, Superalloys, Titanium, Hard Material\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\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 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: STR440.2\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: 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 03084152\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559026164018,"sku":"03084152","price":95.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74690dbde8e491cb9e69a759064cb5f9.jpg?v=1786426096","url":"https:\/\/voomisupply.com\/products\/seco-03084152-corner-radius-end-mill-3-8-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
