Built from M42 cobalt high-speed steel, it delivers the heat and wear resistance needed when cutting steel, stainless steel, cast iron, and high-temperature alloys. The cutting diameter is 0.4375 inches (7\/16 inches), with a 0.8125-inch (13\/16 inches) length of cut and a 0.375-inch (3\/8 inches) shank diameter. Overall length is 2.5 inches. The 30-degree spiral flute geometry promotes efficient chip evacuation, while the centercutting design allows plunge entry. The bright, uncoated finish suits applications where coating is not required or where regrinding is expected.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for short-reach milling operations in job shop, tool room, and production environments. The SP205 series targets applications in steel and stainless steel where a cobalt substrate provides a cost-effective alternative to carbide. Typical operations include slotting, profiling, and peripheral milling. It is designed for use in manual mills and CNC machining centers running appropriate feeds and speeds for M42 cobalt tooling. The right-hand cut and right-hand flute orientation are standard for conventional spindle rotation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for improved red hardness over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with regrinding and general-purpose use\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — standard orientation for most milling setups\u003c\/li\u003e\n\u003cli\u003eShort length type minimizes overhang and improves rigidity in tight setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style tooling solution for milling steel, stainless steel, cast iron, and high-temperature alloys.

Confirm the holder TIR does not exceed the tool specification before use. Power down and lock out the machine before changing tooling. Do not exceed the recommended depth of cut for a two-flute cobalt end mill in hard or abrasive materials, as overloading will cause premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.4375 inches (7\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.8125 inches (13\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 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\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\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\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: 17011642\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557678448946,"sku":"17011642","price":53.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/686dc3695ff3f36c37307c60b1cee92c_3c3007e2-f7fb-43c4-a5d0-498da76230ee.jpg?v=1786392648","url":"https:\/\/voomisupply.com\/products\/seco-17011642-square-end-mill-7-16-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
