TNMG160408 T9235 Turning insert by Tungaloy — CVD-coated carbide, 60° triangular form

The TNMG160408 T9235 is an ISO-format triangular insert for external and internal turning, designed to deliver reliable performance on steel where interrupted cuts or unstable setups occur.

• CVD-coated carbide grade T9235
• Suited to steel and interrupted cuts
• ISO TNMG 160408 triangular insert
• 0.8 mm corner radius, 60° insert angle

Reliable cutting under unstable conditions

The insert provides robust performance where fixture rigidity or interrupted cuts challenge process stability. The CVD-coated surface on the carbide substrate improves wear resistance and helps maintain a stable cutting edge during variable engagement. With a 60° triangular geometry and 0.8 mm corner radius, the component balances edge strength and versatility: it resists chipping better than finer radii while preserving access to smaller profiles. This makes the part well suited for workshops needing dependable results when clamping or workpiece support cannot be fully optimised.

Longer effective tool life and consistent surface quality

Choosing the T9235 grade brings a combination of toughness and thermal resistance tailored for steel machining at moderate speeds. The grade is formulated to withstand shock and generate predictable wear behaviour, which can reduce tool change frequency and improve process economics. The double-sided chipbreaker design allows reversing the insert to use the second cutting edge, effectively doubling usable life per index. As a result, operational interruptions are reduced and finish consistency on turned components is improved, especially where surface integrity is critical.

Compatibility, mounting and application guidance

Compatibility with holders depends on form, relief angle, tolerance class, clamping and plate thickness; the insert has a 4.76 mm plate thickness and is supplied with a cylindrical hole for secure mounting. The ISO classification clarifies fitment: ISO TNMG 160408 indicates the size and shape standard, which helps shops select the correct external holder or boring bar. The relief angle is 0°, suitable for many conventional turning holders. When selecting a holder, ensure matching pocket geometry and clamping hardware to keep the insert stable during cuts.

How to select the right chipbreaker and cutting strategy

The double-sided chipbreaker supplied on this triangular insert offers a balance between chip control and cutting forces. For heavily interrupted or unstable conditions, a tougher grade like T9235 combined with conservative cutting data reduces the risk of edge failure. For finishing passes, consider a reduced depth of cut and slightly higher spindle speed while maintaining consistent feed to enhance surface finish. The insert’s triangular shape provides three indexing positions per side, offering good cost-efficiency for batch work and general-purpose turning tasks.

FAQ

What materials is this insert designed to machine?
The TNMG160408 T9235 insert is designed primarily for steel machining; the T9235 grade is a tough CVD-coated carbide optimised for interrupted cuts and unstable conditions when turning steel.

How is holder compatibility determined for this insert?
Compatibility depends on form, relief angle, tolerance class, clamping method, plate size and thickness; the ISO TNMG 160408 designation and the 4.76 mm plate thickness guide the selection of a matching external holder or boring bar.

Can the insert be indexed to extend usable life?
Yes — the triangular geometry and double-sided chipbreaker permit multiple indexing positions, allowing reversal and rotation to access fresh cutting edges.

What does the 0.8 mm corner radius mean for machining?
A 0.8 mm corner radius offers increased edge strength versus finer radii, improving resistance to chipping in interrupted operations while still allowing acceptable detail in turned profiles.

Is the insert suitable for finishing passes?
The insert can be used for finishing with appropriate cutting data adjustments; a stable setup, reduced depth of cut and consistent feed will enhance surface finish when using this CVD-coated carbide grade.
