TNMG 160404 T9235 Wendeplatten - Tungaloy

The combination of a CVD-coated carbide grade and a robust triangular geometry delivers reliable performance in unstable and interrupted turning operations; the T9235 grade is tailored for steel applications at lower cutting speeds and improves tool life under shock loads. The reversible, double-sided design and secure cylindrical-hole clamping reduce tooling costs and simplify inventory.

TNMG 160404 T9235 — TNMG indexable turning insert for turning, Tungaloy

The TNMG160404 T9235 is an ISO-compliant triangular indexable insert engineered as a tough, CVD-coated carbide grade for external and internal turning, optimised for interrupted cuts and unstable machining conditions.

• CVD-coated carbide T9235 for steel
• Triangular 60° geometry, 0.4 mm radius
• Double-sided, reversible cutting edges
• Cylindrical hole, 4.76 mm plate thickness

Reliable performance for unstable and interrupted turning

The T9235 grade is a CVD-coated carbide developed to offer toughness where interrupted cuts and unstable setups challenge tool life. In practice, the tougher substrate and coating combination suppresses edge chipping and extends the usable period between indexings, which in turn lowers the overall cost per component. This behaviour is particularly beneficial for batch work and repair turning where sudden tool impacts can occur; the result is more predictable production and fewer unplanned stoppages.

Geometry and clamping that support process stability

A triangular 60° plate with a 0.4 mm corner radius balances robustness and edge utility, delivering a compromise between finishing quality and strength for light roughing. The insert’s 4.76 mm plate thickness and central cylindrical hole ensure secure mechanical clamping in suitable holders. Compatibility with a given holder is determined by the insert form, 0° relief angle, tolerance class, fastening method, size and thickness; selecting a matching holder and clamp maintains repeatable seating and concentricity, which directly improves surface finish and tool life.

Cost efficiency through reversible, double-sided design

The double-sided layout with an integrated chipbreaker offers multiple indexable edges, making the insert reversible and economical for high-volume or mixed-run production. Using the second cutting face after indexing halves the tooling requirement for the same number of effective edges compared with single-sided alternatives. As part of an ISO tooling system the insert works together with an appropriate external holder or boring bar, plus shim/clamp kits and spare screws, simplifying stock planning and maintenance procedures.

Practical selection advice and process benefits

Choose a chipbreaker and grade that match the workpiece material and machining stability; this model’s chipbreaker design and tough substrate suit steel workpieces, particularly under lower cutting speeds or interrupted engagement. For external and internal turning tasks the combination of chip control and edge robustness reduces rework and tool-change frequency. Where surface finish is critical, pair the insert’s geometry with light feeds and stable clamping to exploit its edge integrity and produce consistent results.

FAQ

Which materials is this insert best suited for? The TNMG160404 T9235 insert uses a tough CVD-coated carbide grade that is optimised for machining steel, especially in cases with interrupted cuts or unstable conditions.

How is the insert secured in the holder? The insert is clamped via its central cylindrical hole; secure seating depends on matching the insert form, tolerance class, 0° relief angle, size and plate thickness with the chosen holder and clamp kit.

Can this insert be indexed to use multiple edges? Yes, the design is double-sided and reversible, providing additional usable cutting edges and improving cost efficiency per edge.

Which holder types are compatible with TNMG160404? Compatible holders are ISO external turning holders or boring bars specified for the TNMG form and size; confirm compatibility by matching form, plate thickness and fastening method to the insert designation.

When should the T9235 grade be chosen over harder grades? Select the T9235 grade when toughness and resistance to chipping are priorities—typical for lower cutting speeds, interrupted cuts or unstable setups where a more wear-resistant but brittle grade would fail
