SNMA120408 T5105 ISO indexable turning insert — CVD-coated carbide, 0.8 mm radius (Tungaloy)

The SNMA120408 T5105 is an ISO-standard square indexable insert for external and internal turning, designed for high-speed machining of cast iron under stable conditions and delivered with a cylindrical fixing hole.

• CVD-coated carbide for wear resistance
• ISO SNMA 120408 square insert
• 0.8 mm corner radius for stable cuts
• 90° geometry with cylindrical hole

Higher throughput through a wear‑resistant cutting grade

The combination of the T5105 CVD-coated carbide grade and a geometry intended for stable setups delivers measurable gains in throughput and consistency. The CVD-coated surface reduces flank wear during extended high-speed cycles, which translates into longer tool life and fewer index changes. For operations focusing on cast iron, the coating and substrate composition favour heat resistance and edge stability, enabling higher cutting speeds without compromising component tolerances. This results in shorter cycle times and more predictable production runs.

System compatibility that simplifies tool setup

Being an ISO-standard SNMA insert, the component fits into established clamping systems where form, clearance angle, tolerance class, fastening method, size and thickness determine compatibility. The square form with 90° geometry and a cylindrical fixing hole ensures secure locating in matched external holders or boring bars. Clear specifications for size (12 mm), thickness (4.76 mm) and the nominal 0.8 mm radius facilitate straightforward integration into existing tool lists and reduce setup time. Where holders are preselected for SNMA inserts, interchangeability supports rapid replenishment and consistent repeatability across batches.

Practical guidance for machining and surface quality

The neutral relief specification and absence of an integrated chipbreaker make this grade especially suitable where a robust cutting edge and predictable chip flow are required; the lack of a built-in chipformer means a chip management strategy should be chosen according to the workpiece and stability of the setup. The 0° relief angle and 0.8 mm radius combine to offer a balance between edge strength and surface finish: the larger corner radius improves load distribution for roughing passes, while maintaining a controllable cutting edge for finishing when machine rigidity permits. Select a chipbreaker and feed rate matched to component geometry to achieve the desired surface integrity with minimal rework.

FAQ

What materials is this insert suitable for?
The Tungaloy SNMA120408 T5105 insert is formulated for machining cast iron under stable cutting conditions and performs well in high-speed turning applications.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm radius increases cutting-edge strength and distributes cutting forces, which is beneficial for heavier cuts and contributes to improved tool life and process stability.

Is a chipbreaker included with the insert?
This grade is supplied without a chipbreaker, allowing selection of a chip control solution tailored to the specific workpiece material and machining setup.

Can this insert be used in standard SNMA holders?
Yes, the insert conforms to the ISO SNMA 120408 form and will fit holders designed for SNMA inserts provided the holder matches form, clearance, tolerance, fastening and thickness requirements.

What is the significance of the T5105 grade?
The T5105 designation indicates a CVD-coated carbide grade optimised for wear resistance and high-speed performance, particularly when machining cast iron with stable fixturing.
