Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention in demanding cuts. The cutter runs 6 flutes with a 30-degree right-hand spiral helix, a 1-inch mill diameter, and a 2-inch length of cut. The bright, uncoated finish is the out-of-box condition and suits applications where coating is applied in-house or where bare HSS cobalt performance is sufficient. Center-cutting geometry allows plunge entry as well as standard peripheral milling. Licensed machinists and CNC operators working in job shop or production environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill fits short-length tooling setups in vertical machining centers and manual knee mills. The SPC408 series is suited for cutting steel, stainless steel, cast iron, aluminum and non-ferrous materials, and high-temperature alloys. The 1-inch shank diameter fits standard ER, Weldon, and side-lock holders with a 1-inch bore. With a 4.5-inch overall length, this tool stays compact for rigidity in short-reach applications where deflection control matters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for elevated heat and wear resistance vs standard M2\u003c\/li\u003e\n\u003cli\u003e6-flute geometry increases feed rates and improves surface finish on finishing passes\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix promotes chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge milling without pre-drilled entry\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with re-coating or direct use on non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eShort length-type body maximizes rigidity and minimizes runout in tight setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with steel, stainless steel, cast iron, aluminum and non-ferrous materials, and high-temperature alloys per SECO SPC408 series application guidelines.

Secure the shank fully within the toolholder to the manufacturer-recommended engagement depth before tightening. Verify runout at the cutting edge with a dial indicator before beginning a cut, keeping TIR within acceptable limits for the operation. Always confirm spindle speed and feed rate are set appropriately for the workpiece material before engaging the cutter.\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\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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\u003eMaterial Grade\u003c\/strong\u003e: 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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\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\u003eCoolant Through\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: 0.0010 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\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\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: 17011834\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563861836082,"sku":"17011834","price":137.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45e003f1f7c442eaf4a97369cd791473_f17b62ec-f7e6-4af1-ba89-e5dd68bb09fc.jpg?v=1786505311","url":"https:\/\/voomisupply.com\/products\/seco-17011834-square-end-mill-1in-6-flute-cobalt-spc408","provider":"Voomi Supply","version":"1.0","type":"link"}
