Tungaloy 6772481 Turning Insert VBMT160404-PSF T9215

Product Description

The TUNGALOY 6772481 is a VBMT160404-PSF turning insert in the T9215 grade, designed for precision metal cutting in CNC and manual lathe applications. It features a 35-degree diamond (V) insert shape with a positive rake angle of 20 degrees and a chamfered and honed cutting edge style for clean, controlled chip formation. The insert is CVD-coated with a multilayer TiCN, Al2O3, and TiN coating sequence, delivering thermal resistance and wear life across a range of ferrous workpiece materials. With a PSF chip breaker geometry, it is suited for finishing and semi-finishing passes where tight tolerances and surface finish are the priority.

This insert is intended for use on steel, stainless steel, and cast iron workpieces, corresponding to ISO material groups P, M, and K, with material grades P10 and P20. It supports multiple operations including turning, facing, boring, back turning, and back boring, making it a versatile option for shops running varied part programs. The VBMT160404-PSF is screw-held in compatible toolholders and is cataloged under ISO code VBMT160404-PSF and industry standard number VBMT 331 PSF. Typical users are CNC machinists and toolroom operators in production and job-shop environments.

Key Features

• CVD multilayer coating: TiCN, Al2O3, TiN for extended wear resistance on ferrous materials
• PSF chip breaker geometry optimized for finishing and semi-finishing cuts
• 35-degree diamond insert shape with positive 20-degree rake for reduced cutting forces
• Chamfered and honed cutting edge for edge stability and controlled engagement
• Two cutting edges per insert for cost-per-edge efficiency
• Multi-use capable: turning, facing, boring, back turning, and back boring

Compatibility

Designed for use in VBMT-style screw-clamp toolholders compatible with the VBMT 331 insert size code. Suitable for machining steel, stainless steel, and cast iron (ISO P, M, K material groups). Conforms to ANSI and ISO insert geometry standards.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom personnel. Ensure the toolholder seat and clamping pocket are clean and free of chips before seating the insert. Secure the insert with the appropriate torx or hex screw to the toolholder manufacturer's specified procedure. Do not exceed the maximum depth of cut specification for the PSF chip breaker geometry; this insert is engineered for light-to-medium finishing passes.
