It features a 7\/16 inch (0.4375 inch) cutting diameter, a 0.015 inch corner radius, and 4 flutes with a right-hand spiral and right-hand cutting direction. The tool is coated with TiAlN via a PVD process, improving heat resistance and extending tool life when cutting hard and abrasive workpiece materials. At 2.75 inches overall length with a 1 inch length of cut, this end mill is suited for both roughing and finishing passes. Licensed machinists and CNC programmers working in job shops or production environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in vertical and horizontal machining centers with a compatible toolholder accepting a 7\/16 inch straight cylindrical shank. It is optimized for cutting steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The centercutting geometry allows plunge entry, and the single-end configuration suits standard tool change workflows. The variable index geometry distributes cutting forces to reduce chatter, making it a practical choice for tight-tolerance slotting, profiling, and peripheral milling operations on difficult-to-machine materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard material cutting\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating improves thermal resistance and tool life in steel and superalloy applications\u003c\/li\u003e\n  \u003cli\u003e0.015 inch corner radius reduces stress concentration and extends edge life at workpiece corners\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flutes with variable index geometry reduce chatter and harmonic vibration\u003c\/li\u003e\n  \u003cli\u003eRated for roughing and finishing in steel, stainless steel, cast iron, superalloys, titanium, and hard materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with toolholders accepting a 7\/16 inch straight cylindrical shank (shank diameter tolerance h6).

Secure the shank fully in a clean, correctly sized toolholder collet or end mill holder and verify runout before cutting. Confirm spindle speed, feed rate, and depth of cut are within the machine tool and toolholder manufacturer recommendations for this diameter and material. Never exceed the rated length of cut to avoid deflection or tool breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inches (0.4375 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: 1 inch (0.7500 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inches (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches\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 End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN (PVD)\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 to -0.0015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VG434\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: VG434-4375\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51729303535922,"sku":"VG434-4375","price":101.53,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/abb800116c1f498d0776cb28b1db5303.jpg?v=1788702658","url":"https:\/\/voomisupply.com\/products\/osg-vg434-4375-corner-radius-end-mill-7-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
