Built from M42 cobalt high-speed steel and coated with TiCN (Titanium Carbonitride), this tool delivers improved wear resistance and longer tool life compared to standard HSS end mills. It features a 7\/16 inch cutting diameter, a 13\/16 inch length of cut, and a 2-flute, right-hand spiral flute geometry with a 30-degree helix angle. The centercutting design allows plunge cutting. Overall length is 2.5 inches with a 3\/8 inch shank diameter. Machinists and tool-and-die shops working with steel, stainless steel, cast iron, and high-temperature alloys use this end mill for slotting, profiling, and peripheral milling operations.\u003c\/p\u003e\n\u003cp\u003eThe 17016373 belongs to SECO's SP205 series, a short-length fractional inch end mill line intended for general-purpose milling in shop and production environments. The short overall length improves rigidity and reduces deflection when cutting harder materials such as stainless steel and high-temp alloys. This tool fits standard 3\/8 inch collet chucks and end mill holders used on vertical machining centers, knee mills, and CNC milling machines. It is sold as a single-end tool, meaning once the cutting end is worn, the tool is replaced rather than reindexed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt substrate for elevated heat and wear resistance versus M2 HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry permits direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand spiral flute for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eShort length-of-cut design maximizes rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eTIR maximum of 0.0010 inches for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for primary workpiece materials including steel (P), stainless steel (M), cast iron (K), and high-temperature alloys (S) per ISO material classification.

Ensure the spindle is fully stopped and locked out before mounting or removing the tool from its holder. Verify collet and holder condition before use — a worn or contaminated collet seat can introduce runout beyond the rated TIR maximum and accelerate tool wear. Set feeds and speeds appropriate to the workpiece material, tool diameter, and machine rigidity; consult the machine manufacturer's guidelines and SECO tooling data for recommended cutting parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 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: 13\/16 inch (0.8125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\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\u003eSeries\u003c\/strong\u003e: SP205\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\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\u003eTIR Maximum\u003c\/strong\u003e: 0.0010 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\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: 17016373\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558483394866,"sku":"17016373","price":58.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/686dc3695ff3f36c37307c60b1cee92c_33d222e0-3c02-442b-9407-efea791203eb.jpg?v=1786413489","url":"https:\/\/voomisupply.com\/products\/seco-17016373-square-end-mill-7-16-inch-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
