CNMG 120408 T515 Turning insert (CVD‑coated carbide, 0° clearance) — Tungaloy

A CNMG 120408 T515 indexable turning insert designed for ISO‑standard external and internal turning, optimised for economical cast‑iron machining and reproducible results

• CVD‑coated carbide T515 for cast iron
• CNMG 120408 geometry, ISO‑compatible
• 0.8 mm nose radius for consistent finishes

Economical turning with durable CVD coating and predictable results

The combination of the T515 grade and a CVD‑coated surface provides a balance between wear resistance and cost‑effectiveness for cast‑iron operations. The CVD layer reduces flank wear and improves heat resistance during interrupted cuts, so cycle times can be reduced without compromising insert life. This makes the insert well suited for batch production and mixed‑lot work where repeatable tool performance and low tooling costs are priorities. The CVD‑coated carbide substrate is the technical basis for consistent chip control and longer edge life under typical turning feeds and speeds.

Secure clamping and ISO compatibility for straightforward setup

Compatibility with the toolholder is defined by form, clearance, tolerance class, fastening and size; the rhombic CNMG shape and mounting with a cylindrical hole ensure secure seating and repeatable positioning. The insert has a plate thickness of 4.76 mm and a plate size of 12 mm, with an 80° approach angle and 0° clearance that suits many standard external and internal holders. The double‑sided chipbreaker design offers two usable cutting edges per side, improving economy through indexable reversal while preserving stable cutting during axial and radial engagement.

Application guidance for reliable surface finish and chip control

For cast‑iron turning select the double‑sided chipbreaker and the 0.8 mm nose radius to balance surface finish and tool strength; the modest nose radius helps achieve good finish without excessive cutting forces. The geometry performs well in both continuous and mildly interrupted cuts; the grade selection supports medium to high cutting speeds typical for economical roughing and finishing passes. When machining unstable set‑ups, choose a more robust approach and adjust feeds to maintain edge life and avoid premature chipping. The insert is manufactured from carbide and intended for turning applications where consistent results and stable chip formation are essential.

FAQ

What materials is this insert intended for?
The Tungaloy CNMG 120408 T515 insert is formulated for economical machining of cast iron; the T515 grade and CVD coating support stable chip formation and extended edge life in such materials.

How is the insert mounted and secured?
The insert fits ISO‑standard CNMG toolholders and is clamped via its cylindrical hole; compatibility depends on form, tolerance, fastening and thickness, matching the insert’s 4.76 mm plate thickness and 12 mm size.

What benefits does the 0.8 mm nose radius provide?
A 0.8 mm nose radius delivers a compromise between surface finish and cutting edge robustness, helping to produce consistent finishes while resisting chipping under moderate cutting forces.

Is the insert reversible and economical?
Yes — the double‑sided chipbreaker offers multiple usable edges, improving cost‑efficiency by allowing indexation to fresh edges without changing the insert geometry.

Which cutting conditions suit this grade best?
The T515 grade with CVD coating is optimised for medium to high cutting speeds in cast‑iron turning; select chipbreaker and feed according to workpiece stability and surface‑finish requirements.
