VBMT 160404 T515 — ISO turning insert (rhombic) by Tungaloy

The VBMT160404-CM T515 is a rhombic ISO turning insert engineered for efficient external and internal turning, particularly optimised for economical machining of cast iron components.

• ISO rhombic insert VBMT160404-CM T515
• CVD-coated carbide for economical cast iron machining
• 0.4 mm corner radius, 5° relief angle
• Cylindrical hole with 40°–60° single-sided countersink

Minimise downtime with robust, CVD-coated carbide performance

The CVD-coated carbide composition of this insert delivers a balance of wear resistance and reliability tailored to cast-iron machining. The T515 grade is formulated to promote stable chip formation and to tolerate varying cutting speeds, which reduces unplanned interruptions and tool changes. For production environments where cycle time and tool life matter, this grade supports predictable edge behaviour and repeatable component quality. The coating also improves resistance to built-up edge and abrasive wear, helping to preserve dimensional accuracy over longer tool life.

Fit-for-purpose geometry and straightforward integration into existing systems

Designed as an ISO‑standard rhombic insert, the component features a 0.4 mm corner radius and a 5° relief angle, ensuring a controlled cutting edge suitable for both finishing and medium-depth cuts. The insert's compatibility with holders depends on shape, relief, tolerance class, fixation method, size and thickness; the system typically comprises the ISO insert, a matching outer holder or boring bar, a shim/clamping set and replacement screws. The central cylindrical hole with a single‑sided countersink (40°–60°) enables secure clamping and rapid indexing, so tool changeovers remain efficient and repeatable.

Practical benefits for process security and machining economy

Selecting the chipbreaker CM and the T515 grade makes this insert particularly economical for operations involving interrupted cuts or variable workpiece stability. The rhombic form and the specified geometry support good surface finish while allowing for robust cut-taking where required. These design choices together improve overall process security: fewer tool failures, more consistent part quality and lower cost per component. For workshop managers, the result is a pragmatic improvement in throughput without compromising on control or repeatability.

FAQ

Which materials is this insert suitable for?
The VBMT160404-CM T515 is optimised for machining cast iron; the T515 grade and the CVD-coated carbide substrate provide the necessary chip control and wear resistance for economical cast‑iron turning.

How is compatibility with tool holders ensured?
Compatibility depends on the insert’s form, relief angle, tolerance class, fixation, size and thickness; the ISO rhombic shape and the central cylindrical hole with single‑sided countersink allow secure mounting in matching holders and boring bars.

What cutting tasks suit the 0.4 mm corner radius?
A 0.4 mm corner radius provides a balance between a fine surface finish and edge strength, making it appropriate for finishing and light to medium roughing cycles in stable turning operations.

Is the insert indexable and how is it secured?
Yes — the insert is indexable; it is secured via the central cylindrical hole with a single‑sided countersink (40°–60°) and requires the corresponding clamping hardware for reliable seating and repeatable indexing.

What advantages does the CM chipbreaker deliver?
The chipbreaker CM is designed to produce controlled chip formation for cast iron, improving surface quality and reducing the likelihood of long, unmanageable chips during standard turning operations.
