It features a 3\/8-inch diameter, a 0.03-inch corner radius, and four flutes with a right-hand spiral and right-hand cutting direction. The tool carries a PVD-applied TiAlN coating that extends tool life by resisting heat and wear at elevated cutting speeds. Micrograin carbide construction provides the hardness and edge retention needed for consistent results in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. This end mill is centercutting and suited for both roughing and finishing operations.\u003c\/p\u003e\u003cp\u003eThe VG434-3754 is designed for use in vertical and horizontal machining centers where a Weldon flat shank toolholder is employed. The stub-length flute geometry and 1\/2-inch length of cut make it well suited for slotting, profiling, and shoulder milling in close-tolerance applications on ferrous and exotic alloys. The variable index geometry helps reduce chatter during aggressive cuts. It is a single-end tool intended for professional CNC machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiAlN PVD coating for heat resistance and extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e0.03-inch corner radius reduces stress concentration and improves corner durability\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry into workpiece\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces vibration and chatter\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank for secure toolholder engagement\u003c\/li\u003e\n\u003cli\u003eSuited for both roughing and finishing passes in a single tool\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with standard Weldon flat shank toolholders accepting a 3\/8-inch shank.

Power down and lock out the spindle before installing or removing the end mill. Seat the Weldon flat shank fully into the toolholder and tighten the set screw against the flat per toolholder manufacturer guidelines. Verify runout with a dial indicator before beginning a cut, as excessive runout will accelerate tool wear and degrade surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inches (1.4961 inches actual)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\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\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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\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\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\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\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: VG434-3754\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51735383146802,"sku":"VG434-3754","price":75.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a59ab3d9250f76fe430cd3341ff46caf.jpg?v=1788772192","url":"https:\/\/voomisupply.com\/products\/osg-vg434-3754-corner-radius-end-mill-3-8-in-4-flute-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
