TNMG160412 T9215 turning insert for turning by Tungaloy

TNMG160412 T9215 is an ISO‑standard triangular turning insert designed for medium steel machining and matched to ISO holders by form, clearance angle and size

• CVD-coated carbide T9215 grade
• Optimised for medium steel turning
• Triangular ISO TNMG 16 × 4.76 mm
• Double-sided chipbreaker with cylindrical hole

Boosted productivity with proven cutting performance

The T9215 grade combines a CVD coating with a wear‑resistant carbide substrate, producing a cutting edge that sustains higher material removal rates in continuous and lightly interrupted cuts. The coated surface reduces adhesive wear and maintains edge stability, which translates directly into longer effective cutting time and fewer insert changes on the shop floor. For turning operations in medium‑hard steels the result is a measurable increase in throughput without sacrificing component quality.

Stable geometry for consistent surface finish

A corner radius of 1.2 mm and the triangular plate form deliver a balance between strength and finish capability. The moderate radius supports robust edge strength during turning, while still permitting acceptable surface integrity on the workpiece. The 4.76 mm plate thickness and the 60° plate angle contribute to mechanical rigidity, reducing chatter and improving repeatability across batches — particularly valuable for production runs where surface uniformity and dimensional consistency are essential.

Ease of use and secure mounting in standard holders

The insert is manufactured to ISO dimensions (TNMG160412) and includes a cylindrical hole, ensuring positive seating in compatible external holders or boring bars. Compatibility is governed by the plate form, clearance angle, tolerance class, fixing style, size and thickness, which makes the component straightforward to specify for existing tool systems. The double‑sided chipbreaker arrangement allows indexability, effectively doubling the number of available cutting edges and reducing tool change frequency in demanding turning operations.

Controlled chip formation and operational economy

The double‑sided chipbreaker is tuned for predictable chip flow with medium steels, supporting continuous swarf evacuation and minimising tool‑edge temperature peaks. Predictable chip behaviour reduces the risk of built‑up edge and surface defects, which in turn lowers scrap rates and rework. The combination of T9215 grade properties and the insert’s geometry helps to secure a cost‑efficient process over the life of the insert, making it a practical choice for shops aiming to optimise cycle times and tool consumption.

FAQ

What materials is this insert intended for?
The TNMG160412 T9215 insert is optimised for medium steel machining; the CVD‑coated carbide composition delivers wear resistance suited to continuous and light interrupted cuts.

How many usable cutting edges does the insert provide?
With a double‑sided chipbreaker and triangular form, the insert offers multiple indexable cutting edges, effectively extending service life before disposal.

Which holders are compatible with this ISO insert?
Compatibility depends on the holder’s form, clearance angle, tolerance class, fixing method, size and thickness; the insert follows ISO TNMG160412 dimensions for straightforward matching.

What advantage does the 1.2 mm corner radius bring?
A 1.2 mm corner radius increases edge strength for interrupted cuts and improves dimensional stability while maintaining a good surface finish in turning operations.

Is the coating suitable for high temperatures?
The CVD coating enhances heat resistance and reduces adhesive wear at elevated cutting temperatures, supporting higher cutting speeds in suitable applications.
