Built from M42 cobalt high-speed steel, this tool delivers hardness and heat resistance needed when cutting steel, stainless steel, cast iron, and high-temperature alloys. The cutting diameter is 0.125 inches with a 0.375-inch length of cut, a 0.375-inch shank diameter, and an overall length of 2.3125 inches. The 2-flute spiral configuration at a 30-degree helix angle promotes chip evacuation and surface finish quality. The bright uncoated finish is standard for cobalt tools used in general-purpose ferrous machining.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and plunge cutting operations in job shops, tool rooms, and production environments. The centercutting geometry allows direct plunge entry without a pre-drilled hole. Primary workpiece materials include steel (P), stainless steel (M), cast iron (K), and high-temperature alloys (S). Right-hand cut and right-hand flute orientation match standard CNC and manual milling machine spindle configurations. This tool belongs to the SECO SP205 series, designed for general-purpose cobalt end milling in fractional inch sizes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for elevated heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e2-flute spiral design with 30-degree helix for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge milling\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — compatible with cutting fluids and dry cutting on ferrous materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute for standard spindle use\u003c\/li\u003e\n\u003cli\u003eNo chipbreaker, no variable helix — straightforward geometry for consistent results\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard milling machines and CNC machining centers accepting a 0.375-inch shank.

Ensure the machine spindle is fully powered down and locked out before changing tooling. Use a properly sized collet or end mill holder rated for the 0.375-inch shank diameter to maintain concentricity within the stated TIR of 0.001 inches. Verify runout with a dial indicator before beginning a cut, and follow the machine manufacturer guidelines for speed and feed recommendations based on workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.3125 inches (2-5\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\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\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 \/ -0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SP205\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 17011624\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558250185010,"sku":"17011624","price":37.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/686dc3695ff3f36c37307c60b1cee92c_7e05f0cb-e0a6-4e1b-80f8-6ea56cc1f31e.jpg?v=1786407371","url":"https:\/\/voomisupply.com\/products\/seco-17011624-square-end-mill-1-8-in-2-flute-cobalt-sp205","provider":"Voomi Supply","version":"1.0","type":"link"}
