Osg VG434-7511 Corner Radius End Mill 3/4 in 4 Flute Tialn

Product Description

The OSG VG434-7511 is a solid carbide corner radius end mill engineered for demanding metal removal in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. It carries a 0.75-inch milling diameter, a 0.06-inch corner radius, and a TiAlN PVD coating that extends tool life in high-temperature cutting environments. The four-flute, single-end geometry supports both roughing and finishing passes. With a 2.25-inch length of cut and a 5-inch overall length, this is a long-reach tool suited for deeper-cavity work where standard-length end mills fall short. Installation is performed by machinists and toolroom technicians running CNC machining centers.

This end mill is designed for use in CNC milling operations on a wide range of ferrous and exotic workpiece materials. The centercutting geometry allows direct plunge entry, and the right-hand spiral flutes evacuate chips efficiently in slotting, profiling, and pocket-milling applications. The 0.75-inch straight-cylindrical shank is compatible with standard toolholders and collet chucks. The long flute length makes it particularly well suited for workpieces requiring deep-profile cuts or multi-pass finishing along steep walls. It belongs to the OSG VG434 series, which targets general-purpose to high-performance milling across P, M, K, S, and H material classes.

Key Features

• Solid carbide construction provides rigidity and wear resistance in hard and abrasive materials
• TiAlN PVD coating improves heat resistance and extends cutting edge life
• 0.06-inch corner radius reduces stress concentration at the cutting edge and improves surface finish
• Centercutting design enables direct plunge milling without a pre-drilled pilot hole
• Long 2.25-inch length of cut supports deep-cavity and deep-wall profiling operations
• Right-hand cutting, right-hand flute direction with normal pitch for stable, predictable chip flow

Compatibility

Designed for use with standard toolholders and collet-style clamping systems. Rated for machining 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 machinists using a compatible toolholder sized for a 0.75-inch straight-cylindrical shank; verify shank seating and runout before initiating a cut. Confirm spindle speed, feed rate, and depth of cut against the machine and workpiece specifications before operation. Inspect the cutting edge and coating for chipping or wear before each use. Do not exceed the tool's rated length-of-cut depth without verifying deflection limits for the specific setup.
