The tool carries a 3\/4-inch diameter with a 0.03-inch corner radius, a 40-degree right-hand helix, and a ZrN (zirconium nitride) coating that extends tool life in ferrous and non-ferrous materials. With three flutes and a 3.25-inch length of cut, this end mill handles deep-pocket and side-milling passes in a single tool. It is installed by machinists and CNC operators working in job shops, tool rooms, and production machining environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for peripheral and slot milling in both roughing and semi-finishing applications. The extra-long 6-inch overall length and 3.25-inch length of cut make it appropriate for deep-cavity work where standard-length tools cannot reach. The corner radius end style reduces corner chipping and stress concentration at the cutting edge, improving tool longevity in aggressive cuts. Right-hand cutting direction makes it compatible with conventional right-hand spindle setups found on virtually all vertical and horizontal CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eZrN coating reduces friction and improves heat resistance during extended cuts\u003c\/li\u003e\n  \u003cli\u003e0.03-inch corner radius reduces edge chipping and lowers stress at tool corners\u003c\/li\u003e\n  \u003cli\u003e40-degree right-hand helix promotes efficient chip evacuation in deep-pocket milling\u003c\/li\u003e\n  \u003cli\u003e3.25-inch length of cut on a 6-inch OAL provides extra reach for deep-cavity applications\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable for plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a drop-in replacement for standard 3\/4-inch straight-cylindrical shank end mills used in CNC machining centers and manual knee mills with ER, CAT, BT, or similar toolholding systems accepting a 3\/4-inch straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the spindle drive before loading or removing the tool from the holder. Ensure the shank is fully seated to the minimum engagement depth recommended by the toolholder manufacturer and that the collet or set-screw holder is torqued per the holder specification. Confirm runout with a dial indicator before beginning production cuts to avoid premature tool wear or workpiece damage.\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: ZrN (Zirconium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 119\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.27 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: PROMAX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 119-04846\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":51971357147442,"sku":"119-04846","price":504.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7b31a28f037c3841f7e631f828f6d84c.jpg?v=1789955788","url":"https:\/\/voomisupply.com\/products\/promax-119-04846-roughing-finishing-end-mill-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
