Built from M42 cobalt high-speed steel, it delivers superior heat and wear resistance compared to standard HSS tooling. The cutter measures 1.25 inches in diameter with a 2-inch length of cut, a 1.25-inch shank diameter, and a 4.5-inch overall length. Six spiral flutes and a 30-degree helix angle combine to improve chip evacuation and surface finish quality. This is a single-end, right-hand cutting, right-hand flute tool with a bright uncoated finish, belonging to the Series SPC408 family. It is centercutting capable, allowing plunge entry into workpieces.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations on a broad range of materials including steel, stainless steel, cast iron, aluminum and other non-ferrous metals, and high-temperature alloys. It is appropriate for use in manual milling machines and CNC machining centers in job shops, production facilities, maintenance departments, and toolrooms. The bright uncoated finish makes it a practical general-purpose choice when specialized coatings are not required by the application.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction provides enhanced hardness and heat resistance over standard HSS grades\u003c\/li\u003e\n\u003cli\u003eSix flutes with a 30-degree right-hand spiral helix for improved chip flow and finish quality\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled entry point\u003c\/li\u003e\n\u003cli\u003e1.25-inch shank diameter matches the mill diameter for rigid, concentric tool holding\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suits general-purpose applications across multiple workpiece material families\u003c\/li\u003e\n\u003cli\u003eSeries SPC408 single-end configuration; no chipbreaker, no variable helix, no coolant-through features\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose replacement or production square end mill for use in standard milling chucks, collet holders, and end mill holders accepting a 1.25-inch straight shank.

The machine spindle must be fully stopped and locked out before inserting or removing the end mill from the holder. Verify that the holder bore tolerance is compatible with the shank diameter tolerance of -0.0001 to -0.0005 inches before mounting. Inspect the cutting edges for chips or damage before each use, and confirm correct tool stick-out and runout with a dial indicator prior to cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.25 inches\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: 1.25 inches\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 HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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 End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\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: +0.0010 \/ -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\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: 17011876\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559934853426,"sku":"17011876","price":209.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/27fd3fe69b0756ffcabcedb7a80600c0.jpg?v=1786444563","url":"https:\/\/voomisupply.com\/products\/seco-17011876-square-end-mill-1-1-4-in-6-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
