It features a 0.4724-inch (12 mm) cutting diameter and a 1.0236-inch (26 mm) length of cut, making it well suited for full-slot and peripheral milling operations that demand dimensional accuracy and edge integrity. The six-flute configuration paired with a 45-degree helix angle promotes smooth chip evacuation and reduces chatter at elevated feed rates. The WXS coating provides thermal resistance and surface hardness, extending tool life in abrasive and high-heat applications. At 0.27 pounds, this single-end mill delivers a solid balance of rigidity and mass for precision machining work.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use on CNC machining centers and manual knee mills where tight tolerances are required in ferrous and hardened workpiece materials. The micrograin carbide substrate supports higher cutting speeds compared to standard carbide grades, making it appropriate for production environments machining P, K, and H material group workpieces. The regular-length body fits standard tool holders and is compatible with 12 mm collets and end mill adapters. It is a single-end tool with right-hand cut and right-hand flute direction, positioned for general-purpose and finishing passes in shop floor and job shop applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for improved wear resistance and edge retention\u003c\/li\u003e\n  \u003cli\u003eSix flutes with 45-degree helix angle for efficient chip flow and reduced vibration\u003c\/li\u003e\n  \u003cli\u003eWXS coating rated for steel, cast iron, and hardened material applications\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows plunge entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand spiral flute for standard CNC spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with 0.4724-inch shank for direct collet or adapter mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for milling steel, cast iron, and hardened materials (material groups P, K, and H).

Torque collet nuts or set screws to the tool holder manufacturer specifications using calibrated tooling. Verify runout with a dial indicator after seating before beginning a cut. Inspect the cutting edges for chips or damage before each use, as carbide tooling is brittle and should not be dropped or subjected to impact.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.4724 inches (12 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.0236 inches (26 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 75 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4724 inches (12 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: WXS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Hardened Materials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 9140\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.27 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 91401211\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51747354280242,"sku":"91401211","price":428.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c863dcc3839228ceda3ffadfe5384ac_9a976776-7cf5-44c1-bd11-51956df2cfba.jpg?v=1788878935","url":"https:\/\/voomisupply.com\/products\/osg-91401211-square-end-mill-0-4724-in-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
