Built from M42 cobalt high-speed steel and coated with TiCN for heat and wear resistance, it handles tough ferrous and non-ferrous materials under high chip loads. The tool features a 3\/4 inch mill diameter, a 4-1\/8 inch length of cut, and a 6-3\/8 inch overall length. Four right-hand spiral flutes with a 30-degree maximum helix angle and a regular length profile make it well suited for roughing passes in production and job shop environments. It is installed by machinists and CNC operators working in metalworking and manufacturing trades.\u003c\/p\u003e\u003cp\u003eThis end mill is used in vertical and horizontal milling operations where roughing cuts on steel, stainless, and similar alloys are required. The TiCN coating reduces friction and extends tool life in interrupted cuts and side milling. The 3\/4 inch shank diameter matches standard ER and side-lock toolholders commonly found in CNC machining centers and manual knee mills. The right-hand cutting direction and spiral flute geometry support conventional and climb milling setups. It is not center-cutting, so plunge milling is not a recommended application for this tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for elevated heat resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces tool wear and lowers cutting friction\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand spiral geometry at 30-degree maximum helix angle\u003c\/li\u003e\n\u003cli\u003e3\/4 inch mill diameter with 4-1\/8 inch length of cut and 6-3\/8 inch OAL\u003c\/li\u003e\n\u003cli\u003eSingle-end design with regular length profile for standard toolholder setups\u003c\/li\u003e\n\u003cli\u003eNot center-cutting — suited for peripheral and side roughing, not plunge entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style roughing end mill for use in standard 3\/4 inch bore milling toolholders on CNC machining centers and manual milling machines performing roughing operations on ferrous and non-ferrous alloys.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the shank fully in the toolholder and torque the retention hardware to the toolholder manufacturer's specification. Verify runout with a dial indicator before commencing a cut, as excessive runout accelerates premature wear on cobalt end mills.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (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\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42)\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: 4-1\/8 inches (4.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\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\u003eMaximum Helix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eSeries\u003c\/strong\u003e: REM710\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: 17015189\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558611747122,"sku":"17015189","price":206.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a98fd236090fa45a0e54e321483dac03_1b9454c0-ef0c-487f-92c2-8e62c0deb34f.jpg?v=1786415795","url":"https:\/\/voomisupply.com\/products\/seco-17015189-roughing-end-mill-3-4-in-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
