It features a 1\/4 inch diameter with a 0.0200 inch corner radius and a TiAlN coating that extends tool life in high-temperature cutting environments. The 4-flute, right-hand spiral geometry with variable helix and variable index design reduces chatter and improves surface finish. With a 3\/8 inch length of cut and a 4 inch overall length, this single-end, centercutting tool handles slotting, profiling, and plunge operations. A Weldon flat shank and extended reach make it well suited to deep-pocket work on CNC machining centers.\u003c\/p\u003e\u003cp\u003eThe 17002062 is engineered primarily for stainless steel machining, where TiAlN coating provides oxidation resistance and hardness at elevated temperatures. The extended reach configuration with a 2-1\/8 inch reach length and a 0.2400 inch neck diameter allows access into deep cavities while the variable helix suppresses vibration. It is appropriate for use on CNC vertical and horizontal machining centers in job shop, aerospace, and medical manufacturing environments where tight tolerances and difficult materials are routine.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with TiAlN coating for extended tool life in stainless steel and high-temp alloys\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index geometry reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design supports plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eExtended reach with 2-1\/8 inch reach length and 0.2400 inch neck diameter for deep-pocket access\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank provides secure tool holding and prevents pull-out under aggressive feeds\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction and right-hand cutting for standard CNC spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/4 inch diameter end mill holders and Weldon-style set-screw toolholders on CNC machining centers.

Ensure the spindle is fully stopped and the machine is in an e-stop or lockout\/tagout state before changing tooling. Seat the Weldon flat against the set screw in the toolholder and torque to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning the first cut, as excessive runout will accelerate edge wear on carbide tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (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\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.2400 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2-1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eExtended Reach\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\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.00100 to -0.00100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000100 \/ -0.002000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 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\u003eSeries\u003c\/strong\u003e: STRN440\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 17002062\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558895780146,"sku":"17002062","price":118.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d39be77445ec8dbd674a01a0d4b8b352.jpg?v=1786422099","url":"https:\/\/voomisupply.com\/products\/seco-17002062-corner-radius-end-mill-1-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
