Built from M42 cobalt high-speed steel, it delivers heat and wear resistance needed for interrupted cuts and tough ferrous materials. The 1\/2 inch cutting diameter pairs with a 2 inch length of cut and a 36-degree high helix angle to clear chips efficiently and reduce chatter. The bright uncoated finish suits applications where coating would be counterproductive or unnecessary. Licensed machinists and tool-and-die professionals select this style of roughing end mill when they need to hog stock fast before finishing passes.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard CNC machining centers, knee mills, and manual milling machines accepting a 1\/2 inch straight shank. The long-series overall length of 4 inches gives additional reach for deeper setups or fixtures that require clearance. Right-hand cut and right-hand flute direction are standard for conventional and climb milling on most horizontal and vertical spindle machines. It is center-cutting, allowing direct plunge entry into the workpiece without a pre-drilled hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for elevated heat resistance and extended tool life in hard or abrasive materials\u003c\/li\u003e\n\u003cli\u003e36-degree high helix angle promotes aggressive chip evacuation and smoother cutting action\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge milling without a starter hole\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with a wide range of cutting fluids and materials\u003c\/li\u003e\n\u003cli\u003eLong-series length type provides extra reach for deep-cavity or obstructed setups\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flutes suit standard spindle rotation on most milling machines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for 1\/2 inch ER or straight-shank collet chucks and milling machine spindles requiring a single-end cobalt roughing end mill in the RHC752 series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is powered down before loading or unloading the end mill. Seat the shank fully in the collet or end mill holder and torque the retention mechanism to the toolholder specification. Verify runout with a dial indicator before committing to a cut, particularly when tight diameter tolerances are required.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 36 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\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\u003eCenter Cutting\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: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: RHC752\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: +0.005 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: 0.2 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: 17014589\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560625635634,"sku":"17014589","price":102.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f208bec3ff78c11bb074a5c151ca60e.jpg?v=1786454963","url":"https:\/\/voomisupply.com\/products\/seco-17014589-roughing-end-mill-1-2-in-3-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
