Built from micrograin solid carbide and coated with AlTiN, it delivers extended tool life and thermal resistance during high-speed cutting operations. The 3 mm cutting diameter and 4-flute design support efficient chip evacuation and surface finish quality. A variable helix geometry reduces harmonic vibration, improving stability in demanding cuts. This tool is part of the STR440M.2 series and is installed and operated by machinists and CNC programmers working in precision manufacturing environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finishing and semi-finishing operations in ferrous hard materials and stainless steel. It is center-cutting with a right-hand flute direction and right-hand cutting direction, making it compatible with standard CNC milling machines and machining centers. The straight cylindrical shank seats directly into standard collet chucks or tool holders sized for a 6 mm shank. Typical applications include die and mold work, aerospace components, and precision part machining where tight tolerances and surface integrity are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides thermal barrier and oxidation resistance at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003eVariable helix design reduces chatter and vibration during aggressive cutting passes\u003c\/li\u003e\n\u003cli\u003e4-flute configuration balances chip evacuation with surface finish quality\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows plunge milling and ramping entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and flute direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style tooling solution for CNC milling machines and machining centers equipped with collet chucks or shrink-fit tool holders accepting a 6 mm straight cylindrical shank.

Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Secure the tool to the manufacturer-specified clamping method for the collet or holder type in use. Verify runout does not exceed the maximum TIR of 0.0005 inches after installation before beginning the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3 mm (0.1181 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 6 mm (0.2362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 58 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm (0.2362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eHelix Type\u003c\/strong\u003e: Variable Helix, 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\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\u003eMaximum TIR\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hard Material, Stainless Steel, High-Temperature Alloys\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: STR440M.2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.58 x 0.5 x 0.5 inches\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: 03083957\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560155840818,"sku":"03083957","price":84.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a2c94fc1fbf25527f8e99e657e36e194_8258fb66-8fd6-4f1b-94e1-d08c19bd8485.jpg?v=1786447698","url":"https:\/\/voomisupply.com\/products\/seco-03083957-square-end-mill-3mm-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
