It features a 1\/8 inch cutting diameter with a 1\/4 inch length of cut and a 1-1\/2 inch overall length. The micrograin carbide substrate is coated with AlTiN via a PVD process, providing thermal resistance and wear protection at elevated cutting temperatures. A variable helix geometry at 40 degrees reduces harmonic vibration and improves surface finish consistency. This tool is center-cutting and single-end, suited for slotting, profiling, and finish passes in high-performance CNC machining applications.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for CNC machining centers and high-speed machining operations where tool rigidity and coating performance are critical. It is well suited for shops and field machinists working with aerospace alloys, medical-grade stainless, and hardened die steels. The short length type and straight-cylindrical shank make it a practical choice for tight-clearance work and benchtop CNC setups requiring consistent tolerances in the 1\/8 inch diameter range. It is part of the SECO STB440.2 series, catalog number STB440.2-0.125-D2-B.0-Z4.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides oxidation resistance and extended tool life in stainless steel and high-temp alloys\u003c\/li\u003e\n  \u003cli\u003eVariable helix at 40 degrees reduces chatter and improves surface finish on difficult-to-machine workpieces\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting and right-hand flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eSpiral flute geometry supports both roughing and finishing material removal in a single tool\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and milling machines accepting a 1\/8 inch straight-cylindrical shank.

Ensure the spindle is fully stopped and locked before inserting or removing the tool from the collet or tool holder. Use a properly sized collet or end mill holder to achieve the shank diameter tolerance range of -0.0001 to -0.0004 inches for secure seating. Verify TIR does not exceed 0.0005 inches after tool installation to maintain dimensional accuracy and prevent premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches (1.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.2500 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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable\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 (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\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: Stainless Steel, High-Temp Alloy, Hardened Materials\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\u003eTIR Maximum\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\u003eManufacturers Catalog Number\u003c\/strong\u003e: STB440.2-0.125-D2-B.0-Z4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.59 x 0.5 x 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 03083824\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51562564124978,"sku":"03083824","price":45.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9c2da7081e67eae2c1be50b89faff7e.jpg?v=1786479871","url":"https:\/\/voomisupply.com\/products\/seco-03083824-ball-end-mill-1-8-in-4-flute-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
