TNMG 160408 T6215 — Tungaloy indexable insert for Turning, CVD‑coated carbide, 0.8 mm radius

The TNMG 160408 T6215 is an ISO‑format, triangular indexable insert designed for productive external and internal turning of stainless steel under stable to mildly interrupted cutting conditions.

• CVD-coated carbide for stainless steel
• ISO TNMG 160408 format
• 0.8 mm corner radius
• Double-sided chipbreaker with hole

Outstanding wear resistance for consistent production

The combination of a CVD‑coated carbide substrate and the T6215 grade delivers high wear resistance and stable cutting edges when machining stainless steel. This material pairing is optimised for extended tool life under continuous operation, which reduces changeovers and improves uptime. The coating acts as a thermal and chemical barrier, slowing flank wear and maintaining edge geometry; as a result, cycle times can be shorter and component tolerances are easier to hold, offering a clear efficiency advantage in series production.

Precision geometry that simplifies holder selection and setup

The insert follows the ISO TNMG 160408 geometry with a 60° included angle and a 0.8 mm corner radius, together with a plate thickness of 4.76 mm and a 16 mm inscribed circle. The design includes a cylindrical centre hole and a double‑sided chipbreaker, allowing the insert to be indexed and turned over to use both cutting edges. Compatibility with a toolholder is determined by form, clearance angle, tolerance class, fastening method, size and thickness; matching the insert to a suitable external holder or boring bar, plus the correct shim/clamp set and replacement screws, ensures secure clamping and repeatable positioning.

Chip control and process stability for improved surface quality

The double‑sided chipbreaker is tailored for turning operations where chip formation and evacuation are decisive for surface finish and tool life. Selecting a chipbreaker and grade based on workpiece material, machining parameters and component stability reduces the risk of built‑up edge and erratic chip flow. For short, interrupted cuts the robust cutting edge of this insert sustains performance; in continuous cuts it helps achieve consistent surface quality. Practical system components—insert, holder, underlay and fastenings—work together to maintain process reliability and predictable results.

FAQ

What materials is this insert best suited for?
The TNMG160408 T6215 insert is optimised for stainless steel machining; the CVD‑coated carbide grade provides wear resistance and edge stability for that material group.

How is the insert mounted and indexed?
The insert is secured via its cylindrical centre hole and clamping system; it is double‑sided so both edges can be indexed for extended tool life.

Which geometry parameters are most important for holder compatibility?
Holder compatibility depends on form, clearance angle (0° for this insert), tolerance class, fastening method, size (16 mm inscribed circle) and plate thickness (4.76 mm).

Can the chipbreaker handle interrupted cuts?
Yes; the robust edge and chipbreaker design are suitable for stable to slightly interrupted cutting conditions, delivering consistent chip control and surface quality.

What system components should be checked before turning?
Verify the external holder or boring bar, the shim/clamp set, and replacement screws for dimensional match and clamping integrity to ensure process repeatability.
