Built from micrograin solid carbide and coated with TiCN (Titanium Carbonitride), it delivers wear resistance and thermal stability across a broad range of workpiece materials. The chipbreaker geometry breaks chips into shorter segments, reducing heat buildup and cutting forces during heavy roughing passes. At 3\/16 inches in diameter with a 3\/8 inch length of cut and 2 inches overall length, this is a compact tool suited for slotting, profiling, and pocketing in tight geometries. It is installed and run by machinists and CNC operators working in job shops, production environments, and tool rooms.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing operations in ferrous and non-ferrous materials where chip control is critical. The 4-flute, right-hand cut and right-hand flute configuration supports conventional and climb milling on vertical mills, CNC machining centers, and manual knee mills. The regular length profile fits standard tool holders without requiring extended reach setups. The TiCN coating makes it a practical choice for applications involving stainless steel, alloy steel, and hardened materials where an uncoated carbide tool would wear prematurely.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves surface hardness and oxidation resistance\u003c\/li\u003e\n\u003cli\u003eChipbreaker geometry reduces cutting forces and controls chip length during roughing\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard milling operations\u003c\/li\u003e\n\u003cli\u003eShank diameter matches mill diameter at 3\/16 inches for direct collet clamping\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style roughing end mill for use in standard 3\/16 inch collets and end mill holders on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or CNC operator using an appropriate collet, shrink-fit holder, or end mill holder rated for the 3\/16 inch shank diameter. Confirm runout at the spindle before commencing a roughing pass, as excessive runout accelerates uneven wear on the chipbreaker geometry. Follow the machine tool manufacturer and tooling guidelines for speed and feed parameters based on workpiece material. Inspect the cutting edges for chipping or coating wear before each use and replace when edge condition degrades.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\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: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\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\/Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.005 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: 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2500489\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51755188846898,"sku":"2500489","price":217.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7dece7e2dd97d5f271de7a925848ac52.jpg?v=1788951984","url":"https:\/\/voomisupply.com\/products\/hertel-2500489-roughing-end-mill-3-16-in-4-flute-ticn-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
