TNMG160412 T9215 indexable turning insert — triangular ISO turning insert for medium steel by Tungaloy

A TNMG160412 T9215 indexable turning insert designed for external and internal turning in medium steel, offering a CVD-coated carbide grade for productivity in continuous to slightly interrupted cuts

• TNMG 160412 triangular ISO insert
• CVD-coated carbide grade T9215
• 60° cutting angle, 1.2 mm corner radius
• Double-sided chipbreaker, cylindrical hole

High productivity through CVD-coated carbide and optimised grade

The insert uses a CVD-coated carbide substrate in grade T9215, which combines elevated wear resistance with dependable fracture toughness to support high productivity in medium steel turning. This balance enables stable cutting performance during continuous and lightly interrupted cuts, reducing unplanned tool changes and increasing effective machining time. The coating improves abrasion resistance on the rake and flank faces, which helps preserve the cutting edge and contributes to consistent surface finish and dimensional stability over longer tool life.

Practical triangular format for economical machining

The TNMG160412 format is an ISO-standard triangular insert with a 60° cutting angle and a 1.2 mm corner radius, designed to deliver a versatile mix of strength and edge definition. Its double-sided chipbreaker layout and cylindrical hole allow straightforward indexing and secure clamping in compatible holders, effectively doubling the number of usable edges per insert compared with single-sided designs. The plate thickness of 4.76 mm and the 16 mm size provide sufficient body support to withstand moderate cutting forces while retaining the ability to produce accurate external and internal profiles.

System compatibility and application guidance for reliable results

Compatibility with a given tool holder is determined by form, relief angle, tolerance class, fastening method, size and thickness; the insert is intended for integration in standard ISO turning systems comprising an insert, appropriate external holder or boring bar, backing pad/clamp set and replacement screws. Selection of the chipbreaker and the T9215 grade should be matched to material, machining type and machine rigidity to achieve optimal chip control and surface quality.

FAQ

What materials is this insert suited for?
The TNMG160412 T9215 indexable turning insert from Tungaloy is optimised for medium steel machining; the T9215 CVD-coated carbide grade offers the wear resistance and toughness suited to continuous and lightly interrupted cuts in steel.

How does the double-sided chipbreaker benefit production?
A double-sided chipbreaker provides two usable cutting edges per plate side, increasing edge economy and reducing tooling cost per edge while maintaining consistent chip control for turning operations.

Which holders are compatible with this TNMG format?
Compatibility depends on insert form, relief angle, tolerance class, fastening and thickness; the TNMG160412 fits ISO-standard holders specified for TNMG inserts and requires the matching clamp set and screws for secure mounting.

Is the insert indexable and how many edges are available?
The triangular TNMG design is indexable and double-sided, offering multiple usable cutting edges that allow economical rotation of the insert to restore cutting performance without full replacement.
