Built from M42 cobalt high-speed steel and coated with TiCN for increased surface hardness and heat resistance, this tool handles tough ferrous and non-ferrous materials where standard HSS tooling falls short. The 3\/4-inch diameter cutter carries four right-hand spiral flutes with a 30-degree maximum helix angle, producing efficient chip evacuation during heavy roughing passes. With a 3-inch length of cut and a 5-1\/4-inch overall length, this is a standard-reach tool suitable for a wide range of milling setups. It is centercutting, allowing plunge entry. Installed by machinists and tool-and-die professionals on vertical and horizontal milling machines and machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for roughing operations in job shop, production, and maintenance machining environments. The TiCN coating extends tool life in abrasive cuts, making it a practical choice when machining alloy steels, tool steels, and similar materials. The 3\/4-inch shank diameter matches the cutter diameter, fitting standard ER or straight-shank collet systems and end mill holders of the same bore size. The right-hand cutting direction and right-hand flute direction are the standard configuration for conventional milling machine spindles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for elevated heat and wear resistance compared to standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and reduces friction during heavy roughing cuts\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eFour right-hand spiral flutes at 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003e3-inch length of cut with 5-1\/4-inch overall length in a regular-length series configuration\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and flute direction compatible with standard milling machine spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-configuration roughing end mill for use in collet chucks, end mill holders, and milling machine spindles that accept a 3\/4-inch straight shank.

Before changing tooling, de-energize the machine and confirm the spindle has come to a full stop. Secure the shank in a properly sized collet or end mill holder and torque the retention fastener per the toolholder manufacturer specification. Confirm runout with a dial indicator before beginning a cut, and follow the machine tool manufacturer guidelines for feed rate and depth of cut when roughing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.25 inches\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\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 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\u003eHelix Angle (Maximum)\u003c\/strong\u003e: 30 degrees\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: REC700\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.003 to -0.000 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\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.062 to -0.000 inches\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: 17016592\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563914690866,"sku":"17016592","price":177.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bad1b005b600d92a1cbf13ab5b0641e8.jpg?v=1786506717","url":"https:\/\/voomisupply.com\/products\/seco-17016592-roughing-end-mill-3-4-in-4-flute-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
