It features a 3\/4-inch cutting diameter, a 2-inch length of cut, and a 0.015-inch corner radius that reduces stress concentration at the tool nose and extends edge life. The micrograin carbide substrate and TiCN coating provide wear resistance and thermal stability at elevated cutting speeds. With 4 right-hand spiral flutes and a centercutting geometry, this tool handles both plunging and peripheral milling in a single setup. It is sold as a single-end tool and is intended for use by machinists and tooling professionals in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finish and semi-finish milling applications where a controlled corner radius is required, such as pocket floors, slots, and contoured surfaces. The long-length configuration with a 6-inch overall length and 3\/4-inch shank diameter makes it appropriate for setups requiring additional reach. Right-hand cutting direction is standard for conventional CNC milling center spindles. The TiCN coating performs well in cast iron, alloy steels, and hardened materials at moderate cutting parameters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.015-inch corner radius reduces notch stress and extends tool life compared to sharp-corner end mills\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for improved rigidity and edge sharpness retention\u003c\/li\u003e\n\u003cli\u003eTiCN coating provides enhanced wear resistance and reduced friction in ferrous materials\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes with a 40-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eLong-length body at 6 inches OAL for extended-reach milling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-application end mill for CNC machining centers and manual mills accepting a 3\/4-inch straight shank in ER, side-lock, or shrink-fit toolholders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician familiar with CNC or manual milling equipment. Ensure the machine spindle is fully stopped and the tool changer or quill is locked before inserting or removing the tool. Shank runout should be verified with a dial indicator after clamping to confirm concentricity within acceptable limits. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth of cut for the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 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\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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: TiCN\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 End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 0.00150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12183621\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730674975026,"sku":"12183621","price":419.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d5702321fcb73c1d329c3cbaaf21c1a_6e121e80-3f20-4468-be21-7803ae9b50cc.jpg?v=1788721282","url":"https:\/\/voomisupply.com\/products\/accupro-12183621-corner-radius-end-mill-3-4-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
