It features a 3\/4 inch cutting diameter with a 0.03 inch corner radius end geometry and a 3-flute configuration that balances chip evacuation with cutting efficiency. The 40-degree helix angle promotes smooth cutting action and reduces vibration during high-feed passes. An AlTiN coating provides thermal resistance and extended tool life in ferrous and hardened materials. This end mill is suited for machinists and tool-and-die professionals running CNC milling operations that demand both roughing capability and a refined finish pass.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard CNC vertical and horizontal milling applications where a single tool needs to handle both stock removal and surface finishing. The 3\/4 inch shank diameter mounts directly into standard ER or side-lock toolholders. With a 3.25 inch length of cut and 6 inch overall length, it is well suited for deep-cavity milling, mold work, and die machining where extended reach into a workpiece is required. The right-hand flute direction and right-hand cutting rotation are compatible with conventional CNC spindle configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4 inch cutting diameter with 0.03 inch corner radius for reduced stress at the cutting edge\u003c\/li\u003e\n\u003cli\u003e3-flute design balances chip clearance and tool rigidity\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle for smooth, low-vibration cutting action\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for high-heat resistance and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e3.25 inch length of cut accommodates deep-cavity and mold machining\u003c\/li\u003e\n\u003cli\u003eSingle-end, right-hand cut configuration for standard CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-fit cutting tool for CNC milling machines accepting a 3\/4 inch straight shank end mill in ER collet, side-lock, or Weldon-style toolholders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully powered down and the tool changer is disabled before mounting or removing the end mill. Seat the shank to the minimum recommended insertion depth per the toolholder manufacturer and torque the retention hardware to the holder specification. Verify runout with a dial indicator before initiating a cutting program.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 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: 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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.27 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: PROMAX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 119-04844\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":51962348175666,"sku":"119-04844","price":502.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba60585a0663c14f851fa73f94a7d56c.jpg?v=1789947621","url":"https:\/\/voomisupply.com\/products\/promax-119-04844-3-4-in-3-flute-corner-radius-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
