It features a 3\/4 inch diameter, a 1\/8 inch (0.1250 inch) corner radius, and four flutes ground from micrograin carbide stock. The TiAlN PVD coating provides thermal resistance and wear protection at elevated cutting speeds. With a 1-1\/2 inch length of cut and 4 inch overall length, it handles both roughing and finishing passes in a single tool. A Weldon flat shank ensures positive drive retention in standard toolholders. It is installed and run by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe VG434-7503 is suited for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The variable index flute spacing reduces harmonic chatter during aggressive cuts, making it effective in both roughing and finishing operations. Its centercutting geometry allows plunge entry, and the right-hand spiral flute direction is compatible with conventional vertical and horizontal machining centers. The Weldon flat shank seats securely in side-lock and shrink-fit toolholders commonly used in production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4 inch mill diameter with 0.0000 \/ -0.0015 inch diameter tolerance for precise fit\u003c\/li\u003e\n\u003cli\u003e1\/8 inch corner radius protects workpiece edges and reduces stress concentration at shoulders\u003c\/li\u003e\n\u003cli\u003eTiAlN PVD coating extends tool life in ferrous, superalloy, and hard-material cuts\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate supports high surface footage and rigid setups\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank provides positive drive engagement and prevents axial pull-out\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces vibration and improves surface finish on long passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard Weldon flat toolholders accepting a 3\/4 inch shank diameter.

Always power down and lock out the spindle before changing tooling. Confirm the Weldon flat is properly aligned with the set screw before torquing the toolholder to prevent run-out. Verify spindle RPM, feed rate, and depth of cut against published cutting data for the specific workpiece material before beginning a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/8 inches (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches (1.0236 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: TiAlN (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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 Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: 0.0000 \/ -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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.9 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VG434\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: VG434-7503\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51733672231218,"sku":"VG434-7503","price":273.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8161e96fee7504bd8bad081c54a1b81.jpg?v=1788757875","url":"https:\/\/voomisupply.com\/products\/osg-vg434-7503-corner-radius-end-mill-3-4-in-4-flute-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
