Built from M42 cobalt high-speed steel, it delivers superior heat and wear resistance compared to standard HSS tooling. The cutter runs a 1.5-inch mill diameter with a 2-inch length of cut, a 1.25-inch shank diameter, and a 4.5-inch overall length. Four spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. The bright, uncoated finish suits applications where coating reactions with the workpiece material are a concern. Machinists and tool-and-die professionals install this end mill in vertical mills, CNC machining centers, and manual knee mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling operations across a broad range of primary workpiece materials including steel, stainless steel, cast iron, aluminum and non-ferrous alloys, and high-temperature alloys. Its centercutting geometry allows plunge entry directly into the workpiece without a pre-drilled hole. The right-hand cut and right-hand flute configuration is standard for conventional spindle rotation. The stub length-of-cut classification keeps the tool profile rigid, reducing deflection in heavier cuts on ferrous and difficult materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction provides elevated red hardness for cutting steel and high-temp alloys\u003c\/li\u003e\n  \u003cli\u003eFour spiral flutes at a 30-degree helix angle for efficient chip flow and surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge milling without pilot drilling\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish compatible with a wide range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eSingle-end, right-hand cut and right-hand flute configuration for standard spindle setups\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.0000 to -0.0030 inches ensures consistent fitment in close-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard end mill holders and collet chucks accepting a 1.25-inch shank diameter.

Secure the shank fully in a clean, properly sized collet or end mill holder to the recommended engagement depth, then torque the retention hardware according to the toolholder manufacturer specifications. Inspect the spindle and holder bore for runout before mounting; maximum TIR for this tool is 0.0010 inches. Never exceed the machine spindle speed and feed rate limits for the workpiece material and tool diameter combination.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5000 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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\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: +0.0000 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\u003eSeries\u003c\/strong\u003e: SPC408\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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: 17011890\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560131887410,"sku":"17011890","price":243.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45e003f1f7c442eaf4a97369cd791473_e61549eb-f098-4f82-959b-34456e5359a6.jpg?v=1786447175","url":"https:\/\/voomisupply.com\/products\/seco-17011890-square-end-mill-1-1-2-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
