TPMT16T308-TM T9225 – TPMT 16T308 ISO turning insert, CVD-coated carbide, 60° (Tungaloy)

TPMT16T308-TM T9225 is a triangular ISO indexable insert for precision turning in industrial machining, designed for medium to heavy steel applications with a robust chip control geometry

• ISO triangular insert for reliable turning
• CVD-coated carbide for increased wear resistance
• Robust grade T9225 for medium to heavy cuts
• 0.8 mm corner radius with 11° rake for chip control

Improve process reliability with a proven insert geometry

The triangular insert is engineered for consistent performance in ISO-standard turning systems. The CVD-coated carbide substrate delivers a favourable balance between wear resistance and toughness, while the T9225 grade is formulated as a robust universal solution for medium to heavy machining of steel. The 60° insert geometry spreads cutting forces over a stable edge, and the 0.8 mm corner radius helps absorb intermittent engagement without sacrificing surface finish. Together, these characteristics reduce the risk of unexpected edge failure and support steady production cycles.

Simple integration and predictable clamping for fast set-up

Compatibility with a tooling system is determined by insert form, relief/rake angle, tolerance class, clamping and thickness. This triangular insert features an 11° rake angle and a 3.97 mm plate thickness, with a cylindrical hole and single-side countersink (40°–60°) for secure seating. The ISO designation ensures easy matching with standard holders and turning bars; selecting the correct clamp and backup plate prevents movement and maintains repeatable cutting conditions. Clear, defined datum features mean shorter set-up times and fewer trial cuts on new batches.

Optimise costs through longer tool life and predictable chip control

By choosing a T9225 grade with a tailored TM chipbreaker, the tool offers improved chip control under varying engagement conditions, which is particularly valuable for interrupted cuts or unstable feeds. The CVD layer increases resistance to abrasive wear and thermal loading, resulting in longer tool life and more consistent component quality over time. For production planners and process engineers, that translates into fewer insert changes, reduced machine downtime and more predictable tooling budgets. If uncertainty remains about grade selection for a specific steel mix or machining strategy, technical advice is available to support the decision.

FAQ

What materials is this insert suited for?
The TPMT16T308-TM T9225 insert is formulated primarily for steel machining and performs well in medium to heavy cutting conditions; its T9225 grade offers toughness for varying engagement.

How does the TM chipbreaker affect machining?
The TM chipbreaker on this indexable insert improves chip control under interrupted or variable cuts, helping to avoid entangling chips and promoting stable surface quality during turning.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, relief angle and clamping style; the ISO designation of the TPMT16T308-TM ensures that standard triangular external or internal turning holders with the correct seat will accept the insert.

Is the insert suitable for interrupted cuts?
Yes, the T9225 grade and the 0.8 mm corner radius are selected to cope with intermittent engagement and variable cutting forces, offering enhanced resilience in interrupted-turning applications.
