Osg VG434-7510 Corner Radius End Mill 3/4in 4-flute Tialn

Product Description

The OSG VG434-7510 is a solid carbide corner radius end mill designed for high-performance milling in demanding metalworking applications. It features a 3/4 inch diameter, a 0.02 inch corner radius, and 4 flutes with a right-hand spiral configuration. The cutting edges are coated with TiAlN via a PVD process, providing thermal resistance and extended tool life when cutting ferrous and hard materials. With a length of cut of 1-5/8 inches and a 4 inch overall length, this tool handles both roughing and finishing passes in a single setup. A variable index geometry reduces harmonic vibration during aggressive cuts.

This end mill is suited for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials in production and job-shop environments. The centercutting design allows plunge entry, and the straight-cylindrical 3/4 inch shank seats directly in standard toolholders. It is appropriate for CNC machining centers and manual mills where consistent corner geometry and surface finish are required on tough workpiece materials.

Key Features

• 0.02 inch corner radius reduces stress concentration at the cutting edge for improved tool life
• TiAlN PVD coating provides high-temperature wear resistance for ferrous and hard-material cutting
• Variable index flute spacing minimizes chatter and vibration during roughing and finishing
• Centercutting design allows axial plunge entry without a pre-drilled hole
• Right-hand cut, right-hand flute spiral with medium helix suits a wide range of feed and speed parameters
• Straight-cylindrical shank with h6 tolerance ensures consistent runout in standard collet and endmill holders

Compatibility

Designed for use with standard toolholders accepting a 3/4 inch straight-cylindrical shank. Rated for primary workpiece materials including steel, stainless steel, cast iron, superalloys, titanium, and hard materials (ISO material codes P, M, K, S, H). Part of the OSG VG434 series.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Before mounting, ensure the toolholder bore and shank are clean and free of chips or burrs. Torque the toolholder to the machine spindle per the spindle manufacturer specifications. Confirm runout with a dial indicator before initiating the first cut, and verify feed and speed parameters against OSG published cutting data for the specific workpiece material.
