Built from M42 cobalt high-speed steel and coated with titanium carbonitride (TiCN), it delivers extended tool life in applications where standard HSS tools wear prematurely. The cutter measures 9\/32 inch (0.2812 inch) in diameter with a 9\/16 inch length of cut, a 3\/8 inch shank, and a 2-5\/16 inch overall length. The two-flute, right-hand spiral geometry with a 30-degree helix angle promotes chip evacuation and reduces cutting forces. It is center-cutting, allowing plunge entry without a pre-drilled pilot hole. This tool belongs to the SP205 series short-length end mill line.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slotting, profiling, and plunge milling in steel, stainless steel, cast iron, and high-temperature alloys. Its short-length classification provides rigidity in tight-tolerance applications and shallow-to-moderate depth-of-cut work. The TiCN coating improves surface hardness and reduces friction against abrasive workpiece materials. Machine shops, tool-and-die operations, and maintenance machinists running manual or CNC milling equipment will find this cutter appropriate for general steel machining and difficult-to-machine alloy work where M42 cobalt outperforms standard M2 HSS.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt high-speed steel construction for improved hot hardness and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and reduces built-up edge on ferrous and high-temp alloy materials\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design permits direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand spiral flutes promote chip evacuation and reduce cutting pressure\u003c\/li\u003e\n  \u003cli\u003eShort-length (SP205 series) geometry provides added rigidity for close-tolerance milling\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.0000 to -0.0030 inch ensures consistent fit in standard toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard fractional-inch shank end mill compatible with 3\/8 inch collets, end mill holders, and milling chucks on CNC machining centers and manual knee mills.

Seat the 3\/8 inch shank fully into the toolholder and torque the retention mechanism to the holder manufacturer's specification. Verify runout against the stated TIR maximum of 0.0010 inch before beginning a cut. Do not exceed the rated length of cut when programming depth-of-cut passes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 9\/32 inch (0.2812 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/16 inch (0.5625 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-5\/16 inch (2.3125 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: TiCN\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\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SP205\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0030 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0005 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0620 \/ 0.0000 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0010 inch\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\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: 17016369\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563773886770,"sku":"17016369","price":46.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/686dc3695ff3f36c37307c60b1cee92c_642ebe44-6298-4d85-9775-7a726b2104f2.jpg?v=1786503159","url":"https:\/\/voomisupply.com\/products\/seco-17016369-square-end-mill-9-32-in-2-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
