VBMT 160408 T505 VBMT160408-CM – ISO turning insert, 35° lead angle (Tungaloy)

A VBMT160408-CM T505 indexable turning insert designed for efficient external and internal turning, optimised for cast iron applications.

• ISO rhombic insert VBMT160408-CM T505
• CVD-coated carbide for economical cast iron machining
• 35° lead angle and 0.8 mm corner radius
• Cylindrical hole with 40°–60° countersink

High productivity through a grade tailored for cast iron

The combination of CVD-coated carbide and the T505 grade delivers a balance of wear resistance and reliable edge stability, making this insert a strong choice for productive turning of cast iron. The applied coating reduces flank wear under intermittent cutting conditions and allows higher cutting speeds without compromising tool life. Specified as an indexable insert, it provides a cost-effective option for serial machining where insert changes are faster than regrinding, supporting a smoother production flow and measurable gains in throughput.

Consistent cutting geometry for predictable results

Engineered with a rhombic 35° lead angle and a 0.8 mm corner radius, the geometry supports controlled engagement and stable cutting forces. The 4.76 mm thickness and the cylindrical hole with a 40°–60° countersink ensure secure clamping and repeatable seating in compatible toolholders. These features improve chip control, reduce vibration risk and contribute to reproducible surface finishes, which is particularly valuable when tight tolerances are required in component turning.

Integration into tooling systems and application guidance

This ISO-series insert is intended for standard turning systems and is used together with a matching external holder or boring bar, appropriate underlay/clamp set and replacement screws. Choice of the CM chipbreaker and T505 grade should match the workpiece stability, the nature of the cut (continuous or interrupted) and the desired cutting speed. Support for selection and setup is available to ensure the insert is paired with the correct holder geometry and clamping method, promoting efficient machining and reduced process variability.

FAQ

What materials is this insert suited for?
The insert is optimised for cast iron applications; the T505 grade and CVD-coated carbide make it effective when machining grey and nodular irons.

How does the CM chipbreaker affect performance?
The CM chipbreaker promotes controlled chip formation for turning operations, improving evacuation and reducing chatter compared with unrestricted geometries.

Which toolholders are compatible with this insert?
Compatibility depends on the holder nose form, clamping method and size; the insert seats in ISO-compatible external holders and boring bars designed for rhombic VBMT plates.

Can this insert be used for interrupted cuts?
Yes, the combination of T505 grade and the plate geometry is suitable for interrupted turning, provided the holder and setup offer sufficient stability.

How is the insert secured in the holder?
The insert uses a cylindrical hole with a one-sided countersink and is clamped with the appropriate screw and clamp set to ensure repeatable seating.

Is the VBMT160408-CM T505 suitable for fine finishing?
The insert can achieve good surface quality when paired with a fine feed and appropriate cutting parameters, leveraging the stable cutting edge of the T505 grade.
