It features a 5\/8 inch diameter, a 2-1\/8 inch length of cut, and a 0.03 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in aggressive profiling and slotting applications. The TiCN coating adds hardness and lubricity at the cutting surface, helping the tool resist heat and abrasion during high-speed cutting. With 4 right-hand spiral flutes and a centercutting design, this end mill handles both ramping and plunging without requiring a pre-drilled entry point. It is sold as a single-end tool in micrograin carbide for consistent edge geometry.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for machining operations in metalworking shops, tool rooms, and production environments. Its long-reach geometry, with a 4-5\/8 inch overall length and 2-1\/8 inch length of cut, makes it appropriate for deep-pocket milling, contour profiling, and finish passes where a standard-length tool cannot reach. The 40-degree helix angle promotes smooth chip evacuation and reduces chatter on finishing cuts. It is installed in CNC machining centers and manual mills by machinists and tool-and-die professionals working to tight dimensional tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.03 inch corner radius reduces edge chipping and stress at part corners during profiling\u003c\/li\u003e\n\u003cli\u003eTiCN coating increases surface hardness and wear resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes with 40-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pilot drilling\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction maintains edge sharpness under high cutting loads\u003c\/li\u003e\n\u003cli\u003eLong-reach geometry with 4-5\/8 inch OAL supports deep-pocket and cavity milling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit cutting tool for 5\/8 inch collet or end mill holder systems used in CNC machining centers and conventional vertical mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists using a 5\/8 inch end mill holder, collet chuck, or shrink-fit toolholder. Ensure the holder and spindle taper are clean and free of chips or debris before seating the tool. Torque retention screws or collet nuts to the toolholder manufacturer specification. Follow shop safety procedures and machine guarding requirements before engaging the spindle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2-1\/8 inches (1.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 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\u003eCorner Radius Tolerance\u003c\/strong\u003e: 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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Configuration\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\u003eMaterial\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\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.68 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: 12183119\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730918834482,"sku":"12183119","price":226.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61fdae706d922a53c3e88e566645cc49.jpg?v=1788724779","url":"https:\/\/voomisupply.com\/products\/accupro-12183119-corner-radius-end-mill-5-8-in-4-flutes-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
