It features a 5\/8 inch diameter, a 2-1\/8 inch length of cut, and a 0.045 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in demanding cuts. With 4 right-hand spiral flutes and a TiCN coating, this end mill handles harder workpiece materials at elevated surface speeds. The micrograin carbide substrate provides rigidity and edge retention. It is a single-end, centercutting design, meaning it can be plunged directly into the workpiece as well as used for peripheral and slot milling.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for job shops and production machining environments working with alloy steels, stainless steels, cast iron, and similar ferrous materials where TiCN coating provides a hardness and lubricity advantage. The long flute configuration with a 4-5\/8 inch overall length accommodates deeper pockets and extended-reach setups on vertical machining centers, CNC knee mills, and similar equipment. It is typically selected when a standard-length end mill cannot reach the required depth without tool holder interference.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.045 inch corner radius reduces edge chipping and improves surface finish at pocket floors and walls\u003c\/li\u003e\n  \u003cli\u003eTiCN coating provides elevated hardness and low friction for improved performance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for high rigidity and edge retention at the cutting diameter\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation in deeper cuts\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute spiral for conventional CNC milling spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard selection for CNC machining centers and manual knee mills using ER, CAT, BT, or HSK toolholders sized for a 5\/8 inch shank diameter.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Seat the shank fully into the collet or end mill holder and torque the retention mechanism to the toolholder manufacturer specification. Verify runout at the cutting diameter before beginning a production cycle, as excess runout accelerates corner radius wear and reduces surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.045 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 0.0015 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0025 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.68 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 12183120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730924732722,"sku":"12183120","price":226.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/db438ced449e9cf8a6761e508856fc9a.jpg?v=1788724871","url":"https:\/\/voomisupply.com\/products\/accupro-12183120-corner-radius-end-mill-5-8-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
