SNMG120412 T515 square turning indexable insert by Tungaloy — CVD‑coated carbide for economical cast‑iron turning

The SNMG120412 T515 is an ISO‑standard square indexable insert for turning, engineered for economical roughing and finishing of cast iron with a double‑sided chipbreaker and a cylindrical locating hole for secure clamping

• CVD‑coated carbide for cast iron machining
• ISO‑standard SNMG 120412 format
• Square 12 mm size, 4.76 mm thickness
• Double‑sided chipbreaker design

Consistent productivity through material and geometry

The combination of a CVD‑coated carbide grade and a precisely formed cutting edge supports economic machining of cast iron with predictable wear behaviour. The CVD coating builds a hard, wear‑resistant surface that delays flaking and keeps the cutting edge sharp for longer, which translates into fewer indexings and lower tooling costs per workpiece. The insert’s corner radius 1.2 mm balances edge strength and surface finish to allow stable cutting parameters without compromising component quality.

Secure seat and standardised format for fast tool changes

Designed to the ISO SNMG profile, the insert fits common external holders and boring bars where geometry, screw position and thickness match. The square 12 mm format and cylindrical hole enable reliable clamping and quick replacement, reducing machine downtime. Since the design is double‑sided, two usable cutting edges per index reduce tooling consumption and support efficient shopfloor logistics while maintaining process repeatability.

Chip control and edge preparation for reliable turning

The integrated double‑sided chipbreaker promotes controlled chip formation and evacuation during interrupted or continuous cuts, lowering the risk of built‑up edge and surface damage. The design works together with a 0° relief angle to present a neutral cutting geometry that suits a wide range of turning operations on cast iron. For machinists seeking consistent surface integrity and long runs between interventions, this insert’s geometry and coating combination is a practical solution.

FAQ

What materials is this insert intended for?
The SNMG120412 T515 is designed primarily for economical machining of cast iron; its CVD coating and grade selection favour chip control and tool life in that material family.

Will the insert fit standard SNMG holders?
Yes. The SNMG120412 follows ISO dimensions for SNMG inserts and will fit holders that match the SNMG 120412 profile, thickness and hole style.

How many cutting edges are available per insert?
The insert is double‑sided, providing two usable cutting edges per index to reduce tooling consumption and changeover frequency.

What is the effect of the 1.2 mm corner radius?
A 1.2 mm corner radius increases edge strength and improves life during heavier cuts while still delivering an acceptable surface finish for many turning operations.

Is this insert suitable for interrupted cuts?
The robust carbide grade and chipbreaker geometry of the SNMG120412 T515 favour interrupted cutting typical in turning cast iron, supporting stable chip formation and controlled edge wear.
