Osg VG434-5000 Corner Radius End Mill 1/2 in 4 Flute Tialn

Product Description

The OSG VG434-5000 is a solid carbide corner radius end mill designed for high-performance milling across a range of demanding workpiece materials. Built on the VG434 series platform, it features a 1/2-inch diameter cutting edge, a 0.03-inch corner radius, and four flutes with a variable index geometry. The tool is finished with a TiAlN PVD coating, which enhances heat resistance and extends tool life in high-speed applications. A Weldon flat shank ensures secure clamping in compatible toolholders. This end mill is suited for both roughing and finishing operations and is installed by machinists and CNC tooling specialists.

The VG434-5000 is intended for use in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It is well-suited for general machining centers and CNC milling applications where corner integrity and surface finish are critical. The centercutting design allows plunge entry, adding versatility in multi-operation setups. The stub-length configuration provides added rigidity in shorter reach scenarios, making it appropriate for high-material-removal-rate passes as well as finish contouring work.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance in hard materials
• TiAlN PVD coating enhances thermal resistance for high-speed and dry cutting
• 0.03-inch corner radius reduces stress concentration and extends edge life
• Variable index geometry helps reduce harmonic chatter during aggressive cuts
• Centercutting design allows direct plunge milling without a pre-drilled hole
• Weldon flat shank for positive retention in standard toolholders

Compatibility

Designed for use with standard toolholders accepting a 1/2-inch Weldon flat shank. Compatible workpiece materials include steel, stainless steel, cast iron, superalloys, titanium, and hard materials (material codes P, M, K, S, H).

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and locked out before mounting or removing the end mill. Confirm the toolholder is clean and free of chips before seating the Weldon flat shank, and verify set screw torque per toolholder manufacturer specifications. Review feeds, speeds, and depth-of-cut parameters for the specific workpiece material before beginning a cut.
