It features a 3\/8 inch diameter, a 0.0150 inch corner radius, and four flutes with a 35-degree helix angle. The TiAlN PVD coating provides thermal resistance and wear protection, making this end mill well suited for roughing and finishing operations in a single tool. The Weldon flat shank ensures secure tool holding in compatible toolholders. This is a single-end, center-cutting design with right-hand flute direction and right-hand cutting direction.\u003c\/p\u003e\n\u003cp\u003eThe VG434-3758 is intended for use in CNC machining centers and milling operations targeting ferrous and exotic alloys. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The regular-length flute configuration and 7\/8 inch length of cut make it a practical choice for general-purpose profiling, contouring, and pocket milling where corner geometry must be maintained. The variable index geometry helps reduce harmonic chatter during aggressive cuts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0150 inch corner radius protects cutting edges and reduces stress concentration at part corners\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating delivers elevated heat resistance for dry and semi-dry cutting in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eFour-flute, variable index geometry reduces chatter and supports both roughing and finishing in a single pass\u003c\/li\u003e\n  \u003cli\u003e35-degree medium helix angle balances chip evacuation with cutting stability in ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive drive and resists pullout in high-torque applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard Weldon flat toolholders.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the Weldon flat fully in the toolholder bore and tighten set screws to the toolholder manufacturer's specified torque before operation. Verify runout with a dial indicator after installation to confirm proper seating before cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0150 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: 7\/8 inches (0.8750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 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 Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\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\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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\u003eCoating\u003c\/strong\u003e: TiAlN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter 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\u003eSeries\u003c\/strong\u003e: VG434\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: VG434-3758\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51736731091250,"sku":"VG434-3758","price":75.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/919377e0e8dc378a5fe3da12e6585b08.jpg?v=1788779581","url":"https:\/\/voomisupply.com\/products\/osg-vg434-3758-corner-radius-end-mill-3-8-in-4-flute-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
