Built from M42 cobalt high-speed steel, it carries a TiCN (Titanium Carbonitride) coating that increases surface hardness and extends tool life compared to uncoated HSS tooling. The cutter measures 0.625 inches in diameter with a 4-inch length of cut, a 0.625-inch shank diameter, and a 6.125-inch overall length. Four right-hand spiral flutes at a 30-degree helix angle provide efficient chip evacuation and smooth cutting action. This is a centercutting tool, allowing direct plunge entry into the workpiece.\u003c\/p\u003e\u003cp\u003eThe 17016429 is suited for milling steel, stainless steel, cast iron, aluminum and other non-ferrous metals, and high-temperature alloys across its full range of compatible workpiece material codes (P, M, K, N, S). Its regular-length profile fits standard milling setups on vertical machining centers, knee mills, and manual bridgeport-style machines. The 4-inch length of cut accommodates deep slot milling, profiling, and peripheral cutting applications where extended reach is not required. It is sold and shipped as a single unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for elevated heat and wear resistance over standard M2 tooling\u003c\/li\u003e\n\u003cli\u003eTiCN coating increases surface hardness and reduces built-up edge on ferrous and high-temp materials\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge milling without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003e4-flute, 30-degree right-hand spiral geometry balances cutting speed with chip clearance\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 0.625-inch straight shank for direct collet or end-mill holder mounting\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement — compatible with flood, mist, or dry cutting setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 5\/8-inch end-mill holders, collet chucks, and shrink-fit tooling systems.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Seat the shank to the full recommended engagement depth in the holder and torque the retention screw per the toolholder manufacturer specifications. Verify runout does not exceed the 0.001-inch TIR maximum before beginning a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eLength of Cut\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-1\/8 inches (6.125 inches)\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\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\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\u003eLength Type\u003c\/strong\u003e: Regular\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 \/ -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: 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SPC408\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\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: 17016429\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560756379954,"sku":"17016429","price":114.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45e003f1f7c442eaf4a97369cd791473_fd9bbe4d-5016-485d-85dc-2d33c775dd3f.jpg?v=1786456649","url":"https:\/\/voomisupply.com\/products\/seco-17016429-square-end-mill-5-8-inch-cobalt-ticn-4-flutes","provider":"Voomi Supply","version":"1.0","type":"link"}
