Part of the STB440.2 series, it features a 0.5 inch mill diameter, a 1 inch length of cut, and a 4-flute configuration with a variable helix angle of 40 degrees. The AlTiN PVD coating provides thermal resistance and extended tool life in aggressive cutting conditions. With a right-hand cutting direction, spiral flute geometry, and centercutting capability, this end mill handles both roughing and finishing operations in a single tool. It is suited for use by machinists and CNC tool-and-die professionals in precision machining environments.\u003c\/p\u003e\u003cp\u003eThis end mill is built for applications in aerospace, mold-and-die, and precision manufacturing where stainless steel and high-temp alloys are common workpiece materials. The short length type and 0.5 inch Weldon flat shank provide rigidity and secure tool holding in standard end mill holders. The single-end configuration and 3 inch overall length make it appropriate for typical vertical machining center setups requiring tight tolerances and consistent surface finishes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.5 inch mill diameter with 0.25 inch nose radius for true ball end geometry\u003c\/li\u003e\n\u003cli\u003e4-flute spiral configuration with variable helix for reduced chatter and improved chip evacuation\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating rated for stainless steel, high-temp alloys, and hardened materials\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank for positive drive and reduced pullout risk\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 0.5 inch end mill holders and collet chucks.

Verify shank-to-holder fit and torque set screws to the holder manufacturer's specification using the appropriate hex key. Confirm runout does not exceed the maximum TIR of 0.0005 inches before beginning a cut. Follow your machine tool builder's guidelines for feeds, speeds, and depth of cut when working with hardened or high-temp alloy workpieces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.25 inches\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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel; High-Temp Alloy; Hardened Materials\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\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0600 \/ -0.0600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: STB440.2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 03083833\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51561080783154,"sku":"03083833","price":161.13,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/760537d97a12e33dfd9672fb6899f645.jpg?v=1786462382","url":"https:\/\/voomisupply.com\/products\/seco-03083833-ball-end-mill-0-5-in-4-flute-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
