It carries a 1.25-inch mill diameter with a 4-inch length of cut, an overall length of 6.5 inches, and a matching 1.25-inch straight shank. The four-flute, spiral-flute geometry runs a 30-degree helix angle with right-hand cut and right-hand flute orientation. Material grade is M42 cobalt, and the finish is bright\/uncoated. Licensed machinists and tool-and-die technicians are the primary installers for this type of tooling.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits milling operations on steel (ISO P), stainless steel (ISO M), cast iron (ISO K), aluminum and non-ferrous metals (ISO N), and high-temperature alloys (ISO S). It is designed for conventional vertical and horizontal milling machines, machining centers, and CNC knee mills where a 1.25-inch diameter, center-cutting tool is required. The centercutting design allows plunge entry as well as side milling and slotting passes. It fits applications requiring extended length-of-cut range starting at 2 inches and above within the SPC408 series envelope.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt steel construction provides higher heat and wear resistance than standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eFour spiral flutes with 30-degree helix angle for efficient chip evacuation in ferrous and non-ferrous cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish compatible with cutting fluids and coolant-flood setups\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for use in standard spindle rotation\u003c\/li\u003e\n  \u003cli\u003eSingle-end design; part of the SECO SPC408 series for consistent dimensional tolerancing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-application tooling selection for milling setups requiring a 1.25-inch diameter, 4-flute cobalt square end mill with a 1.25-inch shank within the SPC408 series.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. Secure the shank in a properly sized end mill holder or collet chuck, verifying runout does not exceed the 0.001-inch TIR maximum for this tool. Power down and lock out the spindle before changing tooling. Do not exceed the recommended depth-of-cut or feed rates for the workpiece material to avoid tool deflection or premature wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 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\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\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 \/ 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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum and Non-Ferrous, High-Temp Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SPC408\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: 0.09 pounds\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: 17011872\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51564175884594,"sku":"17011872","price":249.26,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45e003f1f7c442eaf4a97369cd791473_0615bfd2-2dad-4d4e-8583-3c3a3409a7c9.jpg?v=1786513330","url":"https:\/\/voomisupply.com\/products\/seco-17011872-square-end-mill-1-1-4-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
