Built from M42 cobalt high-speed steel and coated with TiCN for improved wear resistance and heat tolerance, this tool handles interrupted cuts and heavy stock removal where standard end mills fall short. It features a 3\/4 inch mill diameter, a 4.125 inch length of cut, and a 6.375 inch overall length. The 4-flute, right-hand spiral configuration with a 30-degree maximum helix angle promotes chip evacuation and stable cutting action. Machinists and tool-and-die professionals working in job shops, maintenance machining, and production environments rely on this style of roughing end mill for fast, efficient roughing passes on steel, stainless, and similar alloys.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is suited for vertical and horizontal milling machine applications where rapid stock removal is the priority before a finishing pass. The center-cutting design allows plunge entry, giving setup flexibility for pocket milling and ramping operations. The 3\/4 inch shank diameter matches the mill diameter, making it compatible with standard ER or end mill holders with a 3\/4 inch bore. It is a regular-length tool appropriate for most general-purpose roughing work that does not require extended reach.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for improved hot hardness and toughness over M2 HSS\u003c\/li\u003e\n\u003cli\u003eTiCN coating increases surface hardness and reduces built-up edge on ferrous materials\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand spiral design with 30-degree maximum helix angle for controlled chip load\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry into workpieces\u003c\/li\u003e\n\u003cli\u003e3\/4 inch shank diameter fits standard 3\/4 inch end mill holders and collet chucks\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration; part of the SECO REC700 series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style roughing end mill replacement for general milling applications requiring a 3\/4 inch diameter, 4-flute, single-end cobalt tool with a 3\/4 inch shank.

Secure the shank fully within the holder to the recommended engagement depth and verify runout before cutting. Do not exceed the tool manufacturer's recommended feed and speed parameters for the workpiece material and machine configuration. Inspect the cutting edges for wear or chipping before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.750 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: 4.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.750 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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0005 inches\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\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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 17015294\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557771542834,"sku":"17015294","price":183.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/75034769c6bcafee62465e34d1cfb3f7_51dd5b90-e01d-42f4-bbf0-027c78541412.jpg?v=1786394805","url":"https:\/\/voomisupply.com\/products\/seco-17015294-roughing-end-mill-3-4-in-4-flute-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
