TNMG 160408 T9215 ISO turning insert for medium‑steel turning — Tungaloy

A TNMG 160408 T9215 is an ISO‑standard triangular turning insert designed for external and internal turning of medium steels, delivering a balance of wear resistance and toughness for continuous to lightly interrupted cuts.

• CVD‑coated carbide grade T9215
• Optimised for medium steel turning
• Triangular ISO plate, 16 mm size
• Double‑sided with cylindrical hole

Increase throughput with a wear‑resistant grade

The T9215 grade is a CVD‑coated carbide developed to combine high wear resistance with reliable fracture toughness, making it a sound choice for productive turning of medium steels. By selecting this grade, production benefits from longer tool life under stable cutting conditions and fewer tool changes, which directly improves machine uptime and lowers per‑part cost. The CVD coating creates a hard, thermally stable surface that reduces adhesion and abrasion in typical steel turning operations.

Robust geometry for repeatable results

The insert features a triangular plate form with an included angle of 60°, a 0.8 mm corner radius, and a plate thickness of 4.76 mm, providing a stable cutting edge and predictable chip flow. The double‑sided design and cylindrical hole with secure clamping allow economical use of both cutting edges and straightforward indexing. Compatibility with a toolholder depends on form, clearance angle, tolerance class, fastening and plate size, so the mechanical fit must be checked when integrating into an existing toolset.

Practical guidance for machining and setup

For turning tasks, choose a chipbreaker and grade that match the workpiece material and the type of cut: the T9215 is recommended for continuous to slightly interrupted cuts in medium steel where a balance of wear resistance and toughness is required. When cracking or edge chipping is likely due to interrupted cuts or unstable setups, consider a more fracture‑resistant geometry or reduced cutting parameters. Insertion into the tool system normally requires a matching outer holder or boring bar, a suitable shim/clamp set and replacement screws to ensure correct seat and repeatability.

Clear advantages for workshop workflows

Using an ISO‑standard insert simplifies inventory and material planning, since holders and spares conform to widely accepted dimensions. The plate’s combination of CVD coating, carbide substrate and standardised form supports consistent surface finish and dimensional control in serial production. For operations seeking productivity gains, the indexable plate offers quick edge changes and lower overall tooling costs compared with brazed or solid alternatives.

FAQ

What materials is this insert suited for?
The TNMG160408 T9215 insert is specified for medium‑range steel machining; the T9215 grade balances wear resistance and toughness for steel turning.

Is the insert reversible and indexable?
Yes, the triangular plate is double‑sided and indexable, allowing reuse of multiple cutting edges before disposal.

What is the corner radius and why does it matter?
The insert has a 0.8 mm corner radius; this radius influences edge strength and surface finish—larger radii increase edge durability but may raise cutting forces.

How is the insert secured in the holder?
The TNMG160408 uses a cylindrical hole and is clamped into a matching ISO toolholder; compatibility depends on form, clearance, tolerance class, fastening and plate size.

Can this insert handle interrupted cuts?
The T9215 grade is intended primarily for continuous to slightly interrupted cuts; for heavily interrupted cutting, choose a more fracture‑resistant geometry or adjust cutting parameters.
