Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention in demanding cuts. It carries a bright uncoated finish, a 30-degree helix angle, and a 4-flute spiral configuration with centercutting capability. At 0.25 inches in diameter with a 1.25-inch length of cut, this is a right-hand cut, right-hand flute tool suited for precise work in steel, stainless steel, cast iron, aluminum, non-ferrous materials, and high-temperature alloys. It is a single-end tool in the SPC408 series.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard vertical and horizontal milling machines, CNC machining centers, and manual knee mills. Its 0.375-inch shank diameter accepts common ER and end mill collet holders. The centercutting design allows direct plunge entry into workpieces. Typical applications include slotting, shoulder milling, and contour milling in job shop, tool and die, and production machining environments. It is sized for light-to-medium material removal where tight tolerance and surface finish matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction provides elevated heat resistance versus standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge milling without pre-drilling\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip evacuation in steel and stainless\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suits use with cutting fluids and in aluminum or non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute, SPC408 series regular-length configuration\u003c\/li\u003e\n\u003cli\u003eNo coolant-through or chipbreaker — straightforward general-purpose geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with workpiece materials including steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys.

Seat the shank fully into the collet or end mill holder and torque the retention hardware to the tool holder manufacturer specification. Confirm runout with a dial indicator before cutting — maximum TIR is 0.001 inches per specification. Apply cutting fluid appropriate to the workpiece material and verify chip clearance before engaging full depth of cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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: +0.0010 \/ -0.0000 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\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0620 \/ 0.0000 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: SPC408\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: 17011708\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558288982322,"sku":"17011708","price":55.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45e003f1f7c442eaf4a97369cd791473_60583aea-0bff-42c2-9983-5c43db899e37.jpg?v=1786408633","url":"https:\/\/voomisupply.com\/products\/seco-17011708-square-end-mill-0-25in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
