DNMG 150612 T5105 Turning insert by Tungaloy — CVD-coated carbide for cast iron turning

The DNMG150612 T5105 is an ISO-standard rhombic turning insert designed for stable external and internal turning, optimised for high-speed machining of cast iron under steady conditions.

• CVD-coated carbide for high-speed cutting
• Optimised for cast iron machining
• Rhombic 55° geometry with 1.2 mm corner radius
• Cylindrical hole — secure mounting

Consistent cutting performance for high-speed turning

The insert’s CVD-coated carbide grade T5105 is developed for high-speed machining of cast iron, providing wear resistance and predictable tool life during continuous production. The chemical vapour deposition layer increases abrasion resistance and thermal stability, which reduces flank wear at elevated cutting speeds. This leads to longer intervals between indexings and fewer tool changes, improving overall process efficiency. The outcome is reduced machine downtime and a more reliable production rhythm when stability in setup and cutting conditions is maintained.

ISO compatibility and secure clamping reduce integration effort

As an ISO-standard plate with defined form and tolerance, the insert integrates into standard toolholding systems with minimal adaptation. The rhombic 55° geometry and a cylindrical hole allow secure mounting on compatible external holders or boring bars, while the specified clearance angle and plate thickness contribute to assembly accuracy. A complete system comprises the ISO insert, a matching external holder or boring bar, a shim/clamping set and replacement screws; correct selection of these components ensures repeatable positioning and reduces vibration-related wear.

Predictable chip control and improved surface finish

The double-sided chipbreaker provides consistent chip formation, supporting stable cutting at higher feed rates and aiding swarf evacuation. The 1.2 mm corner radius balances edge strength and the ability to produce a smooth surface finish in semi-finish to finishing passes. A plate thickness of 6.35 mm contributes to rigidity, decreasing chatter risk and enabling more aggressive but controlled cutting conditions where the workpiece and setup provide adequate support. The result is reliable part geometry and a reproducible surface quality during series production.

FAQ

What materials is this insert best suited for?
The DNMG150612 T5105 insert from Tungaloy is optimised for machining cast iron, where its CVD-coated carbide composition offers strong wear resistance under high-speed conditions.

Can the DNMG150612 be used for internal turning as well as external turning?
Yes, the ISO-standard geometry and secure cylindrical hole mounting make the insert suitable for both external and internal turning when paired with the appropriate holder or boring bar.

How does the 1.2 mm corner radius affect cutting performance?
A 1.2 mm corner radius increases edge strength and contributes to a better surface finish on semi-finish and finishing passes, while also supporting stable cutting in repetitive production.

Is the insert reversible or indexable?
The DNMG150612 is a double-sided indexable insert, allowing multiple cutting edges to be used before replacement, which extends effective tool life.

Which toolholder features are required for correct assembly?
Correct assembly requires a holder compatible with ISO DNMG geometry, suitable clearance for the 0° relief angle, and a secure clamping system; matching the plate size and thickness ensures accurate seating.
