Part of the XG-400 Series, it features an AlTiN coating that improves heat resistance and extends tool life at elevated cutting temperatures. The 3\/4 inch diameter cutter has a 1 inch length of cut (LOC) and a corner radius range of 0.028 to 0.030 inches, allowing it to produce smooth corner transitions while reducing stress concentrations in machined parts. With 4 flutes and a fine pitch, this end mill delivers a strong balance of chip evacuation and surface finish. It is centercutting, enabling plunge entry when required.\u003c\/p\u003e\u003cp\u003eThe XG-400-24 is suited for finish milling, profiling, and contouring operations in CNC machining centers. The stub length configuration keeps the tool stiff and minimizes deflection in tight-tolerance cuts. Its right-hand cutting and right-hand flute direction are standard for conventional CNC vertical and horizontal milling setups. This tool is appropriate for machinists and tool-and-die professionals working in job shop, aerospace, mold, and general precision manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for extended tool life in high-temperature cutting applications\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.028 to 0.030 inches reduces edge chipping and part stress risers\u003c\/li\u003e\n\u003cli\u003e4 flutes with fine pitch for improved surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge milling entry\u003c\/li\u003e\n\u003cli\u003eStub length design minimizes deflection in precision cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitment for CNC machining centers and manual mills accepting a 3\/4 inch shank diameter tool holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Secure the 3\/4 inch shank in a clean, properly sized collet or end mill holder and torque to the holder manufacturer specification. Verify runout with a dial indicator before beginning a production cut. Always power down the spindle and confirm it has stopped completely before changing tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.028 to 0.030 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Fine\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\u003eHelix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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\u003eSeries\u003c\/strong\u003e: XG-400\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ROBBJACK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: XG-400-24\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBBJACK","offers":[{"title":"Default Title","offer_id":52114874106162,"sku":"XG-400-24","price":509.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f54e6a8e3eb5975d02535f8a318e754c_0feed298-32c2-4a91-b845-f5178d6e5a26.jpg?v=1790079365","url":"https:\/\/voomisupply.com\/products\/robbjack-xg-400-24-corner-radius-end-mill-3-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
