Built from M42 cobalt high-speed steel and coated with TiCN, it provides increased hardness and heat resistance compared to standard HSS tooling. The cutter measures 0.75 inches in diameter with a 3-inch length of cut, making it a long-series tool well suited for deep-pocket and shoulder milling. Four right-hand spiral flutes with a 30-degree helix angle promote efficient chip evacuation. The center-cutting geometry allows plunge entry without pre-drilling. Machinists and tool-and-die professionals select this series for production runs on ferrous and non-ferrous workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThe 17016433 is rated for use on steel, stainless steel, cast iron, aluminum and non-ferrous alloys, and high-temperature alloys, covering material codes P, M, K, N, and S. The long length-of-cut range, starting at 2 inches and extending to 3 inches, makes this tool a practical choice for mold work, fixture machining, and deep-slot applications where standard-length end mills cannot reach. The 0.75-inch shank diameter is compatible with standard ER and side-lock tool holders used in CNC machining centers and manual knee mills. Right-hand cut and right-hand flute configuration is the standard for conventional and climb milling on these platforms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS substrate for elevated hot hardness and wear resistance over standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life on steel and stainless applications\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand spiral flutes promote chip evacuation in deep cuts\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eLong-series geometry with 3-inch length of cut for deep-pocket and shoulder milling\u003c\/li\u003e\n  \u003cli\u003eNo chipbreaker, no variable helix, no coolant-through — straightforward geometry for general production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the SECO SPC408 series.

Secure the 0.75-inch shank in a clean, properly sized collet or end mill holder and torque to the tool-holder manufacturer's specification. Confirm runout does not exceed the 0.0010-inch TIR maximum before beginning a cut. Inspect the cutting edges and coating for chips or wear before each use; a damaged TiCN coating accelerates edge breakdown on hardened materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.25 inches (5-1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\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: Cobalt (M42 HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut Range\u003c\/strong\u003e: 2 inches and above\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0620 \/ 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003eSeries\u003c\/strong\u003e: SPC408\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 17016433\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51562820337970,"sku":"17016433","price":115.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45e003f1f7c442eaf4a97369cd791473_0c3c9864-17ce-4ead-8e1d-36d98ad393c2.jpg?v=1786485153","url":"https:\/\/voomisupply.com\/products\/seco-17016433-square-end-mill-3-4-in-4-flute-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
