Osg VGM5-0140 Corner Radius End Mill 1/2 in 5 Flute Carbide

Product Description

The OSG VGM5-0140 is a solid carbide corner radius end mill designed for high-performance material removal in demanding machining environments. Built on OSG's VGM5 platform, it features a 0.5 inch mill diameter, 5 flutes, and a 0.0100 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in abrasive materials. The EXO coating provides enhanced wear resistance and heat dissipation, making this end mill well suited for aggressive cutting cycles in both roughing and finishing operations. A variable index geometry helps suppress chatter and vibration during high-load passes. Machinists and CNC operators working with ferrous and hard materials will find this tool capable of handling tight tolerance work without sacrificing material removal rate.

The VGM5-0140 is engineered for use in steel, stainless steel, cast iron, superalloys, titanium, and hard materials. With a 1.25 inch length of cut and a 3 inch overall length, it suits standard vertical machining center setups and is compatible with straight-bore toolholders accepting a 0.5 inch shank. The single-end, centercutting configuration allows plunge entry and full helical interpolation, which is common in die and mold work as well as aerospace component machining where complex pocket geometry is the norm.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• EXO coating reduces friction and heat buildup, extending tool life in ferrous and superalloy cuts
• 5-flute design increases feed rate capability while maintaining chip evacuation in moderate-depth cuts
• Variable index flute spacing actively reduces harmonic vibration and chatter during heavy milling passes
• 0.0100 inch corner radius protects the cutting edge and improves surface finish at floor transitions
• Centercutting geometry permits plunge milling and helical ramping without a pre-drilled pilot hole
• Right-hand cut, right-hand spiral flute direction compatible with standard CNC spindle rotation

Compatibility

Designed for use with standard straight-bore toolholders accepting a 0.5 inch cylindrical shank. Intended for machining steel, stainless steel, cast iron, superalloys, titanium, and hard materials as noted in OSG VGM5 series application guidelines.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before inserting or removing the tool from the toolholder. Verify shank seating depth and runout with a dial indicator before beginning any cut cycle. Follow the toolholder manufacturer's torque specifications for set screws or collet nuts — do not overtighten, as carbide shanks are brittle and can fracture under excessive clamping force.
