Built from M42 cobalt high-speed steel, it delivers greater heat and wear resistance than standard M2 HSS tools, making it well suited to interrupted cuts and harder alloys. The cutter measures 0.625 inches in diameter with a 3-inch length of cut and a 5.125-inch overall length. Four spiral flutes with a 30-degree helix angle promote efficient chip evacuation and a stable cutting action. The bright, uncoated finish maintains a sharp edge out of the box. This tool is installed by machinists and toolroom operators in manual mills, knee mills, and CNC machining centers.\u003c\/p\u003e\u003cp\u003eThe 17011752 is appropriate for milling 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 regular-length geometry and 0.625-inch shank diameter make it a direct fit for standard end mill holders, collet chucks, and Weldon-flat holders used in both job shop and production environments. The centercutting design allows plunge entry, expanding the range of operations to include slot milling, profile milling, and pocket ramping without a pre-drilled pilot hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for improved heat resistance and tool life over standard HSS in tough alloys\u003c\/li\u003e\n\u003cli\u003eFour spiral flutes with 30-degree helix angle for effective chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration — standard orientation for conventional and climb milling\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish maintains a sharp edge and suits a broad range of materials without coating compatibility concerns\u003c\/li\u003e\n\u003cli\u003eSeries SPC408 regular-length sizing for straightforward toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use cobalt end mill for standard 0.625-inch end mill holders, collet chucks, and Weldon-flat holders used in vertical milling machines and CNC machining centers.

Ensure the spindle is fully powered down and the machine is locked out before changing tooling. Verify holder bore and collet size match the 0.625-inch shank diameter and confirm the tool is seated to the correct gauge length before torquing the drawbar or clamping screws. Never exceed the tool manufacturer's recommended speed and feed parameters for the workpiece material being 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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.125 inches (5-1\/8 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\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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\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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 17011752\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51562755916082,"sku":"17011752","price":113.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45e003f1f7c442eaf4a97369cd791473_053cc42d-d1d0-42e0-9230-aa179443ec10.jpg?v=1786483982","url":"https:\/\/voomisupply.com\/products\/seco-17011752-square-end-mill-5-8-in-4-flute-cobalt-spc408","provider":"Voomi Supply","version":"1.0","type":"link"}
