Built from M42 cobalt high-speed steel, it delivers heat resistance and edge retention in demanding cuts. The 1.5-inch cutting diameter pairs with a 1.625-inch length of cut and a 30-degree helix angle for efficient chip evacuation. Two spiral flutes and a centercutting geometry allow both plunge and peripheral milling. The 1.25-inch shank diameter suits standard milling chucks and collets common on vertical and horizontal machining centers. Machinists and tool-and-die professionals working in job shops and production environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling steel, stainless steel, cast iron, and high-temperature alloys. Its uncoated bright finish makes it a practical choice in applications where coating adhesion or re-sharpening economics are priorities. The right-hand cut, right-hand flute configuration is standard for conventional and climb milling on CNC mills and manual Bridgeport-style machines. With an overall length of 4.125 inches and a non-extended-reach profile, it fits most standard toolholding setups without requiring special adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for elevated heat resistance and wear life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute geometry for conventional milling setups\u003c\/li\u003e\n  \u003cli\u003eUncoated bright finish compatible with regrinding and re-use cycles\u003c\/li\u003e\n  \u003cli\u003eTwo-flute configuration provides chip clearance in tougher, stickier alloys\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard milling operations on steel, stainless steel, cast iron, and high-temperature alloys.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the toolholder. Verify shank runout and toolholder cleanliness before securing; excess runout accelerates edge wear. Follow machine manufacturer torque specifications for collet nuts and set-screw holders — do not over-tighten.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 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\u003eOverall Length\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\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\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High-Temp Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SP205\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.25 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: 17011668\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558068814130,"sku":"17011668","price":234.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d7f036acf0c66b5cc86c586452c0dc0.jpg?v=1786402515","url":"https:\/\/voomisupply.com\/products\/seco-17011668-square-end-mill-1-1-2-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
