TNMG220412 T5105 indexable turning insert — CVD-coated carbide, triangular 60° geometry, Tungaloy

The TNMG220412 T5105 is an ISO-standard triangular indexable insert for turning, optimised for high-speed machining of cast iron under stable cutting conditions.

• CVD-coated carbide for high-speed turning
• ISO-standard triangular insert, 60° geometry
• Double-sided chipbreaker for reliable chip control
• 1.2 mm corner radius, centring hole with cylindrical bore

Increased process efficiency through optimised carbide grade

The CVD-coated T5105 grade combines a wear-resistant coating with a tough substrate to deliver predictable tool life in sustained high-speed applications. By selecting a CVD-coated carbide insert with a balanced coating-substrate system, machine shops benefit from reduced flank wear and extended intervals between indexings. The rational advantage is clear: fewer unscheduled tool changes lower downtime, while consistent cutting-edge performance supports repeatable part tolerances and higher throughput on turning centres and conventional lathes.

Reliable fit and simple integration into ISO holder systems

As an ISO-standard turning insert, compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness. The insert features a triangular 60° geometry, a plate size of 22 mm and a plate thickness of 4.76 mm, together with a cylindrical centring hole, which facilitates accurate seating in compatible external holders or boring bars. Understanding these parameters enables precise holder selection and stable clamping, ensuring the insert performs as intended without trial-and-error adjustments. Clear technical specifications make planning for tool inventories and holder assortments straightforward.

Predictable machining results and improved chip control for cast iron

The double-sided chipbreaker and the 1.2 mm corner radius support controlled chip formation in external and internal turning operations on cast iron. The chip geometry produced by the chipbreaker reduces the risk of tangled or long chips, improving process safety and simplifying post-process handling. The 1.2 mm corner radius provides a practical balance between edge strength and surface finish, suitable for general-purpose turning where both tool life and component quality matter.

Practical handling and system considerations for daily workshop use

The insert is supplied as part of a system that includes the indexable plate, a matching external holder or boring bar, a clamping pad or clamp set and replacement screws. This system approach ensures that replacement is quick and repeatable, helping to maintain spindle stability and minimise setup time. The ISO-standard format also supports inventory rationalisation: stocked sizes and grades enable rapid changes between jobs and consistent performance across batches, which is especially valuable in small to medium production runs and maintenance workshops.

FAQ

What materials is this insert designed for?
The TNMG220412 T5105 insert is formulated for high-speed machining of cast iron; the T5105 CVD-coated carbide offers controlled wear and stable cutting when used under suitable conditions.

Can this insert be used in internal turning operations?
Yes, the triangular TNMG220412 insert is suitable for both external and internal turning when paired with the correct boring bar or holder and appropriate cutting parameters.

How does the chipbreaker affect machining performance?
The double-sided chipbreaker on this insert improves chip control and reduces the risk of long, entangling chips, contributing to safer and more consistent turning cycles.

Which holder features must be checked for compatibility?
Compatibility is determined by the holder form, clearance angle, tolerance class, fastening method, insert size and thickness — ensure the holder accepts a 22 mm triangular insert with a 4.76 mm plate thickness and a central cylindrical hole.

What benefits does the 1.2 mm corner radius provide?
A 1.2 mm corner radius increases edge strength compared with smaller radii and helps achieve a good surface finish for general turning tasks while extending tool life.
