VBMT160408-CM T5115 ISO turning insert by Tungaloy — CVD-coated carbide, 0.8 mm corner radius

VBMT160408-CM T5115 is an ISO turning insert designed for external and internal turning, offering a universal grade optimised for cast-iron machining.

• CVD-coated carbide grade T5115
• Universal grade for cast iron machining
• Rhombic 16 mm form, 0.8 mm corner radius
• Cylindrical hole with 40°–60° countersink

Consistent edge stability and wear resistance for cast iron

The combination of a CVD-coated surface and a wear-resistant carbide substrate provides a balanced performance profile: the T5115 grade offers enhanced wear resistance while maintaining edge stability under interrupted cuts and varying feed conditions. The modest 0.8 mm corner radius increases edge strength for heavy engagement, reducing chipping risk, while the CM chipbreaker is tuned to produce controlled chip shapes in cast iron, improving evacuation and lowering the chance of re-cutting. This results in longer tool life and fewer insert changes, supporting steady throughput in mixed-batch production.

Secure clamping and precise geometry for repeatable results

ISO standardisation ensures predictable seating and interchangeability with compatible toolholders: form, 5° clearance angle, tolerance class, fastening, 16 mm size and 4.76 mm thickness determine fit. The rhombic geometry with a 35° included angle gives flexibility for both finishing and semi-finishing operations, while the cylindrical hole with one-sided countersink (40°–60°) provides a stable mechanical seat and reliable torque transfer to the clamp. These measurable attributes support reproducible set-ups and less downtime during tool changes, particularly where tool-change precision is essential.

Shop-floor advantages and economical machining

Selecting an indexable insert with a balanced grade such as T5115 reduces per-part tooling costs through extended life and predictable wear behaviour. The chip control inherent to the CM chipbreaker minimises built-up edge and improves surface quality with fewer secondary operations. For job shops and production lines handling grey cast iron, the combination of ISO conformity, robust chipbreaker design and the rhombic profile offers a practical route to higher machine utilisation, reduced scrap rates and consistent part finish — especially on parts where dimensional stability and surface integrity are priorities.

Practical guidance for holder choice and application

Compatibility with a holder is defined by the insert’s form, 5° free angle, tolerance class, fastening method, size and thickness; the ISO series described here fits holders specified for VBMT-style rhombic inserts. Use the CM chipbreaker where medium to heavy interrupted cuts are expected in cast iron; choose stable clamping and a rigid setup to exploit the insert’s edge security. Where surface finish is critical, favour the smaller feeds and the rhombic nose positions; for higher metal removal rates opt for the stronger corner engagement provided by the larger corner radius and a conservative depth of cut. If further advice on matching holders or cutting parameters is required, consultants at Metav Werkzeuge can provide application-oriented recommendations.

FAQ

What materials is this insert optimised for?
The VBMT160408-CM T5115 insert is a universal grade optimised for cast iron, providing a balance of wear resistance and edge stability suitable for grey cast iron machining.

Which chipbreaker is fitted and what is its effect?
The insert features a CM chipbreaker, which promotes controlled chip formation in cast iron and reduces chip-related interruptions, aiding consistent surface quality.

How does the insert locate in the holder?
Locating depends on form, tolerance class, fastening and thickness; the cylindrical hole with one-sided countersink (40°–60°) ensures a secure mechanical seat for reliable clamping and repeatability.

Can this insert be used for internal as well as external turning?
Yes, the rhombic 16 mm form and 35° included angle make the insert suitable for both external and internal turning operations when combined with the correct holder geometry.

What measurable dimensions should be checked for compatibility?
Check the plate size (16 mm), thickness (4.76 mm), corner radius (0.8 mm), clearance angle (5°) and ISO code (160408) to ensure compatibility with a chosen toolholder.
