VBMT 160404 GT9530 – ISO turning insert for finishing by Tungaloy

The VBMT160404-PSF GT9530 is an ISO‑standard rhombic insert intended for external and internal turning, offering a PSF chipbreaker and a coated cermet grade for finishing operations on steel.

• Coated cermet grade GT9530 for finishing
• ISO rhombic insert, 16 mm size
• PSF chipbreaker for stable chip control
• 0.4 mm nose radius for fine surface quality

Consistent finishing results with a cermet cutting edge

The coated cermet composition of the GT9530 grade is engineered for low abrasion and wear resistance, which translates into longer intervals between index changes and a better surface finish in finishing passes. Cermet combines ceramic hardness with metallic toughness to reduce built‑up edge and provide a fine, repeatable part appearance; the 0.4 mm nose radius supports tight surface roughness targets without compromising edge strength. In practice this means fewer interruptions for regrinding and more predictable component quality on stable set‑ups.

Reliable tool life and process stability under controlled conditions

Built for stable cutting conditions, the insert’s geometry and coating reduce flank wear and maintain a sharp cutting edge over longer tool life. The combination of a 35° cutting angle and a 5° clearance angle helps to distribute cutting forces and limit rubbing, while the insert plate thickness of 4.76 mm contributes to stiffness in the clamped system. The PSF chipbreaker promotes short, controllable chip forms suitable for finishing steel, improving machine uptime and reducing secondary operations—an efficiency gain that supports tighter production schedules.

Straightforward integration for holders and process planning

Compatibility with toolholders is determined by insert form, clearance angle, tolerance class, fastening style, size and thickness; the rhombic ISO geometry and the specified hole with cylindrical bore and single‑side countersink (40°–60°) permit mounting in common ISO turning holders and boring bars. Selection of the PSF chipbreaker and the GT9530 grade should follow the workpiece material, machining method and setup rigidity; the insert forms part of a system consisting of an ISO insert, a matching outer holder or boring bar, a clamp/seat set and replacement screws, making procurement and spare‑parts management straightforward for production environments.

FAQ

Which materials is this insert best suited for?
The VBMT160404‑PSF GT9530 is optimised as a finishing to light universal grade for steel, delivering improved surface quality and extended life under stable cutting conditions.

What benefit does the PSF chipbreaker provide?
The PSF chipbreaker produces short, controlled chips for finishing, improving chip evacuation and reducing the risk of surface damage during turning operations.

How does the ISO designation relate to the insert geometry?
The VBMT160404‑PSF designation indicates a rhombic ISO insert with a nominal 16 mm size and a 0.4 mm nose radius; the suffixes specify the chipbreaker and grade.

Can the insert be used for internal turning as well as external?
Yes, the geometry and chip control of this insert make it suitable for both external and internal turning applications when paired with an appropriate holder or boring bar.

What should be checked when matching the insert to a holder?
Verify holder compatibility by matching the insert form, clearance angle, tolerance class, fastening method, size and thickness to ensure correct seating and clamping stability.
