Built with four flutes and a variable helix geometry, it promotes smooth chip evacuation and reduces chatter across a range of materials. The 3\/8 inch mill diameter pairs with a 1\/2 inch length of cut and a 6 inch overall length, making it well suited for deep-cavity and extended-reach work. An AlTiN PVD coating provides thermal resistance and wear protection at the cutting edge. The Weldon flat shank ensures positive drive retention in compatible holders.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for machining steel, cast iron, aluminum, and other non-ferrous materials in CNC milling applications. The extended reach and 3-5\/8 inch neck length allow the tool to access deep pockets, slots, and contoured features that standard-length end mills cannot reach. It is center-cutting and right-hand cutting with a right-hand flute direction, so it can plunge directly into a workpiece. Typical installation scenarios include die and mold work, aerospace component machining, and general metalworking on vertical or horizontal machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and long tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides oxidation resistance and extended performance at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eVariable helix geometry reduces harmonic vibration and chatter during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eExtended reach design with 4-1\/8 inch reach length and 3-5\/8 inch neck length for deep-cavity access\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable for direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank for secure, positive drive in set-screw style toolholders\u003c\/li\u003e\n  \u003cli\u003eBall nose profile supports both roughing and finishing passes on contoured surfaces\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 that accept 3\/8 inch Weldon flat shank toolholders.

Ensure the spindle is fully stopped and the machine is in a safe state before loading or removing the tool. Seat the Weldon flat fully into the toolholder bore and torque the set screw 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\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inches (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 3-5\/8 inches (3.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.3600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 4-1\/8 inches (4.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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: Weldon Flat\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\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\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: STBN440\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Cast Iron, Aluminum, Non-Ferrous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.35 pounds\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: 17002082\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563900305714,"sku":"17002082","price":261.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6b4d3333929c9392db5fa4de5ea4c6ba_84eb6eda-e4d3-4275-b76c-7f71cc32c97f.jpg?v=1786506319","url":"https:\/\/voomisupply.com\/products\/seco-17002082-ball-end-mill-3-8-in-4-flute-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
