It features a 3\/4 inch cutting diameter, a 1-5\/8 inch length of cut (LOC), and a corner radius range of 0.055 to 0.065 inches. The 4-flute geometry with a 40-degree high helix angle promotes efficient chip evacuation and smooth surface finishes. A TiCN coating adds hardness and wear resistance, making this end mill suitable for ferrous and non-ferrous materials alike. Machinists and tool-and-die professionals install this tool in CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and finishing passes in production and job-shop environments. The centercutting design allows plunge entry into the workpiece, adding versatility in multi-axis operations. The fine pitch classification and right-hand cutting and flute direction are standard for general milling applications in both ferrous alloys and harder non-ferrous materials. The 3\/4 inch shank diameter matches common ER and end mill holder sizes found in most machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4 inch cutting diameter with 1-5\/8 inch length of cut for medium-depth milling passes\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.055 to 0.065 inches reduces edge chipping and stress at part corners\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and dimensional stability at higher feed rates\u003c\/li\u003e\n\u003cli\u003eTiCN coating increases surface hardness and wear resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003e40-degree high helix angle promotes chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without a pre-drilled pilot hole\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/4 inch end mill holders, collet chucks, and ER-style tooling systems commonly found in CNC machining centers and manual knee mills running right-hand spindle rotation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's tooling guidelines. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Secure the shank to the full recommended engagement depth in the tool holder and torque the retention mechanism according to the holder manufacturer's specification. Verify runout with a dial indicator before beginning cuts to confirm proper seating.\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: 1-5\/8 inches\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: 0.055 to 0.065 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees (High)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Fine\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\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\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\u003eSeries\u003c\/strong\u003e: 101\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: 101-04812\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":52083679265074,"sku":"101-04812","price":404.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/826b13cac7248a685771cb5fbb541d79.jpg?v=1790057651","url":"https:\/\/voomisupply.com\/products\/promax-101-04812-corner-radius-end-mill-3-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
