Built from M42 cobalt high-speed steel and finished with a TiCN (Titanium Carbonitride) coating, it handles elevated cutting temperatures and abrasive workpieces better than standard HSS tooling. The cutter measures 0.750 inches in diameter with a 2.000-inch length of cut and a 4.250-inch overall length. A 30-degree right-hand spiral helix promotes efficient chip evacuation and smooth cutting action. This tool is center-cutting, allowing direct plunge entry. It is suited for CNC machining centers and manual mills operated by machinists and toolroom technicians.\u003c\/p\u003e\u003cp\u003eThe 17016432 is designed for use in metalworking environments where steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys are the primary workpiece materials. The TiCN coating extends tool life when cutting abrasive materials. A 3\/4-inch shank diameter fits standard collet chucks and end mill holders common on vertical machining centers and knee mills. This tool belongs to the SECO SPC408 series, which targets general-purpose and production milling across job shops and manufacturing facilities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction provides hardness and heat resistance beyond standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and wear on abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix promotes efficient chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge milling without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 4 flutes balances surface finish quality with material removal rate\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.0000 to -0.0030 inches ensures consistent fit in close-tolerance setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003ePart of the SECO SPC408 series.

Ensure the spindle is fully stopped and the machine is powered down before mounting or removing the end mill. Seat the shank fully in the holder to the recommended engagement depth and torque the set screw or collet nut per the holder manufacturer's specification. Inspect runout with a dial indicator before cutting — TIR maximum for this tool is 0.0010 inches.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.7500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting 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\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0030 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0005 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\u003eWeight\u003c\/strong\u003e: 0.3 pounds\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: 17016432\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563983339826,"sku":"17016432","price":120.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45e003f1f7c442eaf4a97369cd791473_2fc8366c-5cf8-487e-893a-c913ffbd631a.jpg?v=1786508447","url":"https:\/\/voomisupply.com\/products\/seco-17016432-square-end-mill-3-4-in-4-flute-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
