Manufactured from M42 cobalt high-speed steel and coated with TiCN for improved wear resistance and heat tolerance, this end mill delivers consistent cutting performance in demanding production environments. It features a 3\/16 inch cutting diameter, a 7\/16 inch length of cut, and a 30-degree helix angle with right-hand cut and right-hand spiral flutes. The two-flute geometry is centercutting, allowing plunge entry as well as conventional milling. Machinists and CNC operators in job shop and production settings are the typical users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for short-reach milling operations on ferrous and difficult-to-machine alloy workpieces. Its 3\/8 inch shank diameter and 2-5\/16 inch overall length fit standard end mill holders, collet chucks, and shrink-fit tooling systems common in vertical and horizontal machining centers. The SP205 series designation indicates it is built to SECO fractional-inch short-length standards, making it a direct fit wherever that series is specified. It is appropriate for slotting, profiling, and plunge milling passes on steel and stainless steel components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction provides elevated red hardness compared to standard M2 HSS, extending tool life in tough materials\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and improves wear resistance for longer run times between tool changes\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip evacuation and reduces cutting forces on ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute geometry compatible with standard CNC and manual milling machine spindle rotation\u003c\/li\u003e\n  \u003cli\u003eShort-length (SP205 series) configuration minimizes overhang and improves rigidity in tight-clearance setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use tool for applications requiring a 3\/16 inch diameter, 2-flute cobalt square end mill in the SECO SP205 short series. Primary workpiece materials are steel (P), stainless steel (M), cast iron (K), and high-temperature alloy (S).\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this end mill should be performed by a qualified machinist or CNC operator familiar with toolholder torque requirements and proper runout inspection procedures. Before mounting, verify that the holder bore and shank are clean and free of chips or burrs. Maximum TIR for this tool is 0.0010 inches; exceed this and premature wear or breakage is likely. Always confirm spindle direction and feed-rate programming match the right-hand cut specification before initiating a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-5\/16 inches (2.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 grade)\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\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SP205\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 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High-Temp Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\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: 1 pound\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: 17016366\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558268174642,"sku":"17016366","price":40.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/686dc3695ff3f36c37307c60b1cee92c_fea0041d-9bb7-4c95-85b5-d81528067abd.jpg?v=1786407924","url":"https:\/\/voomisupply.com\/products\/seco-17016366-square-end-mill-3-16-in-2-flute-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
