Built from M42 cobalt high-speed steel, it provides greater heat and wear resistance than standard HSS tools, making it suitable for tougher cuts and longer run times. The tool features a 0.625-inch mill diameter, a 2.5-inch length of cut, and a 4.625-inch overall length. Four spiral flutes with a 30-degree helix angle and a bright uncoated finish support chip evacuation and surface finish in general-purpose milling. The centercutting geometry allows the tool to plunge directly into the workpiece. This is a single-end tool in the long-length SPC408 series.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for machining steel, stainless steel, cast iron, aluminum and other non-ferrous materials, and high-temperature alloys. It fits typical milling applications on vertical mills, CNC machining centers, and manual knee mills where a long-reach tool is needed. Right-hand cut and right-hand flute configuration follow standard spindle orientation for most setups. The long length of cut makes it useful for deep-pocket and side-wall milling where a standard-length tool cannot reach.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for improved heat resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003e4 spiral flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with or without cutting fluid\u003c\/li\u003e\n\u003cli\u003eLong series SPC408 with 2.5-inch length of cut for deep-reach applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tool for milling operations requiring a 5\/8-inch shank end mill with long-series reach in steel, stainless steel, cast iron, aluminum, non-ferrous, and high-temperature alloy applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or end mill holder matched to the 0.625-inch shank diameter to maintain runout within specification. Follow the machine manufacturer guidelines for tightening torque and confirm tool runout does not exceed the maximum TIR rating before beginning a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.5 inches (2-1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.625 inches (4-5\/8 inch)\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\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\u003eSeries\u003c\/strong\u003e: SPC408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\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\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: 17011751\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558994641202,"sku":"17011751","price":96.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45e003f1f7c442eaf4a97369cd791473_e986e3bc-0d7f-4ecd-aa83-10b956f60914.jpg?v=1786425216","url":"https:\/\/voomisupply.com\/products\/seco-17011751-square-end-mill-5-8-in-4-flute-cobalt-spc408","provider":"Voomi Supply","version":"1.0","type":"link"}
