Built from M42 cobalt high-speed steel, it delivers hardness and heat resistance suited to tough ferrous and non-ferrous materials. The mill measures 1 inch in cutting diameter with a 2-inch length of cut and a 4.5-inch overall length. The 30-degree helix spiral flute geometry promotes efficient chip evacuation and stable cutting action. The bright uncoated finish is standard for this series. It is installed and operated by machinists and tool-and-die professionals on manual or CNC milling machines.\u003c\/p\u003e\u003cp\u003eThis end mill is rated for use on steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys, covering ISO material groups P, M, K, N, and S. The SPC408 series short-length configuration suits general-purpose face milling, slotting, profiling, and peripheral milling in job shop and production environments. The centercutting geometry allows plunge entry directly into the workpiece without a pre-drilled hole. Right-hand cut and right-hand flute direction are standard for conventional milling machine setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for improved red hardness over standard HSS\u003c\/li\u003e\n\u003cli\u003e4-flute spiral design with 30-degree helix for balanced chip load and surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge milling\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating buildup risk on aluminum or non-ferrous stock\u003c\/li\u003e\n\u003cli\u003e1 inch shank diameter with tight tolerance for secure tool holder engagement\u003c\/li\u003e\n\u003cli\u003eShort-length SPC408 series geometry reduces deflection in standard-depth cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for standard 1-inch-bore milling chucks, collet holders, and end mill adapters used with manual and CNC vertical milling machines accepting 1-inch straight shanks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist. The machine spindle must be fully stopped and locked out before inserting or removing the end mill from the tool holder. Confirm shank seating depth and runout with a dial indicator before cutting — maximum TIR for this tool is 0.0010 inches per specification. Follow shop-standard torque procedures for the tool holder style in use; do not exceed holder manufacturer specifications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut 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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eMaximum TIR\u003c\/strong\u003e: 0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SPC408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\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: 17011828\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560987689266,"sku":"17011828","price":122.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45e003f1f7c442eaf4a97369cd791473_968116dd-a22e-4814-a05c-92e18c1af622.jpg?v=1786460678","url":"https:\/\/voomisupply.com\/products\/seco-17011828-square-end-mill-1-inch-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
