Built to Series 119 standards, it features a 3\/16-inch diameter, three flutes, and a 0.01-inch corner radius that reduces stress concentrations at the cutting edge. The ZrN (zirconium nitride) coating improves wear resistance and surface finish quality. With a 40-degree helix angle and right-hand cutting direction, this stub-length tool delivers aggressive chip evacuation while maintaining tight tolerances. It weighs 0.03 pounds and is suited for machinists and toolroom technicians running CNC mills or manual milling equipment.\u003c\/p\u003e\n\u003cp\u003eThis end mill is appropriate for use in precision machining environments where combined roughing and finishing passes are required on a single setup. The corner radius geometry makes it well suited for mold and die work, profiling, and contouring operations where sharp internal corners must be avoided. Its stub-length configuration provides added rigidity in shallow-to-moderate depth cuts. The micrograin carbide substrate supports higher spindle speeds and feeds compared to standard carbide grades, making it a practical choice for ferrous and non-ferrous workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for extended tool life and edge retention\u003c\/li\u003e\n  \u003cli\u003eZrN coating reduces friction and improves wear resistance at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e0.01-inch corner radius reduces edge chipping and stress at the tool tip\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation during aggressive passes\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction and straight-cylindrical shank for standard collet or end mill holder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 3\/16-inch straight-cylindrical shank.

Ensure the spindle is fully stopped and machine is powered off before changing tooling. Secure the shank to the full recommended engagement depth in the collet or end mill holder to prevent pullout under load. Verify runout with a dial indicator before beginning a production run.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.01 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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 Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: ZrN (Zirconium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002000 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\u003eSeries\u003c\/strong\u003e: 119\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: PROMAX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 119-01226\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROMAX","offers":[{"title":"Default Title","offer_id":51972374823218,"sku":"119-01226","price":79.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f6c33f965a3a86d993b07d813f5b5a8.jpg?v=1789967102","url":"https:\/\/voomisupply.com\/products\/promax-119-01226-corner-radius-end-mill-3-16-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
