VNMA160404 T5105 indexable insert — ISO rhombic turning insert for cast-iron, CVD-coated carbide — Tungaloy

VNMA160404 T5105 is an ISO‑format indexable insert for external and internal turning, engineered for high‑speed machining of cast iron under stable set‑up conditions.

• VNMA160404 geometry, ISO standard
• CVD-coated carbide grade T5105
• 0.4 mm nose radius for fine finishes
• Cylindrical-hole design for secure clamping

High-speed cast-iron performance for longer tool life

The CVD-coated cemented carbide in grade T5105 is formulated for wear resistance during elevated cutting speeds when machining cast iron. This provides predictable tool life and consistent surface quality under stable machining conditions. The coating layer reduces abrasive wear and helps maintain the cutting edge for longer intervals, which translates into fewer indexings and reduced tool costs per part. The result is improved process efficiency and a steadier surface finish on turned components.

Precise fit in ISO turning systems reduces set-up errors

As an ISO‑compliant rhombic insert, the geometry and dimensions determine compatibility with holders and bars. Match the insert form, clearance angle (0°), tolerance class, fastening method, size and thickness to the chosen toolholder to ensure correct seating. The rhombic outline with a 35° lead angle and a 0.4 mm nose radius balances edge strength with finish capability: a smaller radius refines surface quality while still offering adequate edge stability for finishing passes. The cylindrical hole ensures secure clamping and reliable repeatability in production environments.

System integration and practical handling to reduce downtime

The insert is intended to be used as part of a system: the ISO insert plus a corresponding external holder or boring bar, a clamp/shim set and replacement screws. No chipbreaker is supplied with this grade, so select an appropriate chip control geometry for the workpiece and cut conditions if required. Correct seating, clean contact surfaces and recommended tightening torque minimise vibration and promote consistent cutting performance. Proper matching of insert grade and toolholder reduces rework, shortens cycle times and supports predictable, productive turning operations.

FAQ

What materials is the VNMA160404 T5105 suited for?
The VNMA160404 T5105 is designed primarily for high‑speed machining of cast iron; the CVD‑coated carbide grade T5105 provides wear resistance suited to stable turning conditions.

How does the 0.4 mm nose radius affect surface finish and strength?
A 0.4 mm nose radius improves surface finish by reducing scallop height during finishing passes while maintaining sufficient edge strength for controlled cutting when the set‑up is rigid.

Is a chipbreaker included with this insert?
This insert is supplied without a chipbreaker; chip control should be achieved by selecting a compatible holder or an alternate chipbreaker geometry when required.

Which toolholders are compatible with this ISO insert?
Compatibility is determined by form, clearance angle, tolerance class, fastening, size and thickness; use an ISO‑compatible external holder or boring bar sized for the VNMA160404 geometry.

What is the plate thickness and how does it influence choice of holder?
The plate thickness is 4.76 mm; ensure the chosen holder accepts this thickness and secures the insert correctly to maintain repeatable cutting performance.
