Built from M42 cobalt high-speed steel, this single-end mill features a bright uncoated finish and a 30-degree right-hand spiral flute geometry. The 5\/16-inch cutting diameter pairs with a 9\/16-inch length of cut, making it well-suited for shallow pocketing, profiling, and slotting operations. Centercutting capability allows direct plunge entry into workpieces. This tool is part of the SP205 short-length series and is installed by machinists and toolroom professionals working with manual or CNC milling equipment.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for milling operations on ferrous and exotic alloy workpieces in both job shop and production environments. The short overall length of 2-5\/16 inches provides rigidity in tight setups or close-tolerance fixtures. The 3\/8-inch shank diameter fits standard collets and end mill holders on vertical milling machines and machining centers. Right-hand cut and right-hand flute orientation match conventional milling configurations. The uncoated bright finish is appropriate for applications where coated tooling is not required or where regrinding is planned.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for heat and wear resistance in ferrous and high-temp alloy cutting\u003c\/li\u003e\n\u003cli\u003e2-flute geometry promotes chip clearance in slotting and full-width cuts\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge milling without pilot drilling\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix for efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eShort-length SP205 series provides added rigidity in compact setups\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish supports regrinding and use with cutting fluids on a wide range of materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use tooling for standard 3\/8-inch collets and end mill holders on vertical knee mills and CNC machining centers.

The machine spindle must be fully stopped and the tool changer or spindle lock engaged before mounting or removing the end mill. Use a properly sized collet or end mill holder torqued per the machine tool manufacturer specifications to avoid runout. Verify TIR at the cutting diameter before beginning production cuts, as maximum TIR for this tool is 0.0010 inches per specification.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/16 inches (0.5625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: Bright\/Uncoated\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\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\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\u003eTIR Maximum\u003c\/strong\u003e: 0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SP205\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\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: 17011636\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558036734258,"sku":"17011636","price":37.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/686dc3695ff3f36c37307c60b1cee92c_319fd23f-1dd5-4d07-b9d6-1999ca07f101.jpg?v=1786401513","url":"https:\/\/voomisupply.com\/products\/seco-17011636-square-end-mill-5-16-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
