VBMT160412-CM T5115 — VBMT 160412, T5115 turning insert (CVD‑coated carbide) by Tungaloy

The VBMT160412-CM T5115 is an ISO‑standard indexable turning insert for external and internal turning, designed to deliver stable chip formation and balanced performance when machining cast iron.

• CVD‑coated carbide grade T5115
• Universal grade for cast iron machining
• ISO VBMT geometry, 4.76 mm thickness

Reliable wear resistance from CVD coating

The CVD‑applied coating on this carbide grade provides a hard, heat‑resistant surface that reduces flank wear and preserves the cutting edge under interrupted cuts. Combined with the universal T5115 formulation, the insert delivers a well‑balanced mix of wear resistance and edge stability that is especially effective for cast iron workpieces. This technical advantage translates directly into predictable tool life and fewer tool changes during production, supporting a smoother machining cycle.

Geometry engineered for consistent finishes and durability

The rhombic VBMT shape and precise geometry contribute to stable cutting conditions. Key geometry data such as corner radius 1.2 mm, clearance angle 5° and a thickness of 4.76 mm ensure a robust edge and effective heat distribution. The insert size corresponds to an inscribed circle of 16 mm, while the nominal geometry angle is 35°. The CM chipbreaker is tuned for chip control in cast iron, helping to maintain surface quality and reduce secondary operations.

Clear guidance on holder compatibility and system setup

Compatibility with toolholders depends on form, clearance angle, tolerance class, fastening method, size and thickness. The ISO designation and the insert’s hole—cylindrical hole with one‑sided countersink (40°–60°)—allow secure clamping in compatible VBMT‑style holders and boring bars. Select the holder that matches these parameters and the intended machining stability; choosing the correct chipbreaker and grade for the application reduces the risk of edge chipping and improves process reliability.

Productivity gains and application fit

As a universal grade tailored for cast iron, this insert supports stable chip formation and broad material coverage, reducing the need for multiple tool variants. The combination of CVD coating, a balanced carbide matrix and a focused chipbreaker design helps to maintain high productivity with consistent surface finish, making it suitable for batch production and mixed‑series machining where process stability is a priority.

FAQ

What materials is this insert designed for?
The VBMT160412‑CM T5115 insert is a universal CVD‑coated carbide grade primarily intended for machining cast iron, offering a balance of wear resistance and edge stability.

Which chipbreaker is fitted and what is its effect?
The insert uses the CM chipbreaker, which improves chip control and contributes to consistent surface quality when turning cast iron with the VBMT geometry.

How does the 1.2 mm corner radius influence performance?
A corner radius of 1.2 mm increases edge strength and improves finish on external and internal turning operations, reducing the likelihood of edge chipping under variable cutting forces.

Is this insert compatible with standard VBMT holders?
Yes—VBMT160412‑CM follows ISO geometry, but holder compatibility must be checked for matching form, clearance angle, tolerance class, fastening and plate thickness before assembly.

What are the identifying codes and SKUs for ordering?
Order using the manufacturer article number 6864689 or SKU 6864689‑Tungaloy for the Tungaloy VBMT160412‑CM T5115 turning insert.
