VBMT 160412 T9225 VBMT160412-PSS – ISO turning insert for turning, by Tungaloy

VBMT160412‑PSS T9225 is an ISO‑standard indexable turning insert intended for medium-to-heavy turning applications, delivering robustness and consistent performance in steel machining.

• ISO‑standard rhombic insert, 35° clearance
• CVD‑coated carbide grade T9225 for toughness
• PSS chipbreaker for medium to heavy turning
• 1.2 mm corner radius for robust cutting edge

Consistent cutting performance for variable conditions

The VBMT160412‑PSS T9225 is built on a CVD‑coated carbide substrate designed to balance wear resistance with toughness. The T9225 grade performs particularly well where interrupted cuts or variable engagement occur, as the coating reduces flank and crater wear while the substrate maintains edge stability. The PSS chipbreaker shapes chips reliably in medium and heavy steel turning, reducing entanglement and supporting steady feed rates. This combination increases process reliability and reduces unscheduled tool changes.

Simple integration into ISO tool systems and fixture setups

Compatibility is governed by form, relief angle, tolerance class, attachment, size and thickness; this insert follows ISO standards for rhombic turning plates, which eases selection of a matching external holder or boring bar. The 35° lead angle and 5° relief angle influence approach geometry and surface contact, helping to control cutting forces and heat input. Using an ISO‑compliant insert base means existing clamping plates, underlay sets and replacement screws integrate without special adaptations, enabling quick tool changeovers and minimal downtime.

Practical benefits: edge life, surface finish and productivity

A 1.2 mm corner radius provides a stronger cutting edge for heavier engagement and contributes to a more uniform workpiece surface by smoothing micro‑irregularities. The CVD coating supports extended tool life under higher thermal loads typical of steel turning, while the PSS chipbreaker optimises chip flow and reduces the risk of built‑up edge. Together, these features translate into fewer interruptions, improved reproducibility and more productive machining cycles with predictable tool replacement intervals.

FAQ

What materials is this insert best suited for?
The VBMT160412‑PSS T9225 insert is optimised for steel machining; the CVD coating and T9225 grade provide a balance of wear resistance and toughness suited to medium‑to‑heavy turning.

How does the PSS chipbreaker affect machining?
The PSS chipbreaker promotes controlled chip formation and evacuation during medium and heavy turning, reducing chip buildup and supporting consistent cutting conditions with the Tungaloy insert.

Which toolholders are compatible with this ISO insert?
Compatibility depends on matching form, size, thickness, relief angle and attachment; the VBMT160412‑PSS follows ISO geometry, so standard holders for VBMT‑type inserts can be used when dimensions and tolerances align.

What is the significance of the 1.2 mm corner radius?
A 1.2 mm corner radius increases edge strength for heavier cuts and helps produce smoother surface finishes, extending effective edge life under tougher engagement.

Does the insert include fastening hardware?
The insert is supplied as the indexable cutting plate; holders, underlays, clamping sets and replacement screws are part of the system and must be selected to match the insert geometry.
