Built from M42 cobalt high-speed steel with a bright\/uncoated finish, it measures 1.25 inches in diameter with a 3-inch length of cut and a 5.5-inch overall length. The 6-flute geometry with a 30-degree maximum helix angle supports chip evacuation and cutting stability during roughing passes. This tool is installed and used by machinists and tool-and-die professionals on CNC mills and manual knee mills where high metal removal rates are required.\u003c\/p\u003e\u003cp\u003eThe 17010415 is suited for roughing passes on ferrous and non-ferrous metals in production and job-shop environments. Its 1.25-inch shank diameter matches the mill diameter, making it compatible with standard R8, CAT, BT, and HSK toolholders of the appropriate bore size. The right-hand cut and right-hand spiral flute direction are standard for conventional and climb milling on most vertical and horizontal machining centers. It is not center-cutting, so plunge entry is not recommended without a pre-drilled pilot hole or ramping entry strategy.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for heat and wear resistance during heavy roughing cuts\u003c\/li\u003e\n\u003cli\u003e6 spiral flutes with 30-degree maximum helix angle for chip flow and cut stability\u003c\/li\u003e\n\u003cli\u003e1.25-inch mill diameter and matching 1.25-inch shank diameter for rigid setup\u003c\/li\u003e\n\u003cli\u003e3-inch length of cut accommodates deep-pocket and side-wall roughing applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard milling machine spindle rotation\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish; no coolant-through feature — suitable for flood or mist coolant externally applied\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 milling toolholders accepting a 1.25-inch shank diameter, including collet chucks, side-lock holders, and hydraulic chucks of the appropriate bore size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and the control in a safe state per shop lockout\/tagout procedures. Secure the shank to the full recommended engagement depth in the toolholder and torque the retention fasteners to the toolholder manufacturer's specification. Because this end mill is not center-cutting, do not plunge directly into solid material — use a ramp, helical, or pre-drilled entry path. Inspect the cutting edges for chipping or wear before each use and replace when surface finish or chip character degrades.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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: Bright\/Uncoated\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: REM445\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.006 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: 1 pound\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: 17010415\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558303367474,"sku":"17010415","price":278.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc02fbdd14cb29a2ef9705c81c46f6d9_eddc7e16-5be2-42d0-b950-beb4c6a2431e.jpg?v=1786409069","url":"https:\/\/voomisupply.com\/products\/seco-17010415-roughing-end-mill-1-1-4-in-cobalt-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
