TNMG160404 T9215 — indexable turning insert for turning, CVD-coated carbide (Tungaloy)

The TNMG160404 T9215 is a triangular ISO indexable insert designed for general turning applications, optimised for medium-steel machining where a balance of wear resistance and fracture toughness is required.

• ISO triangular insert, CVD-coated carbide
• 0.4 mm corner radius for precise profiles
• Double-sided chipbreaker for productive turning
• Cylindrical hole, 60° geometry for stable clamping

High wear resistance that sustains productivity

The CVD-coated carbide grade T9215 provides a combination of wear resistance and fracture strength that keeps tool life predictable in medium-steel operations. This coating system reduces flank wear at elevated cutting speeds and helps maintain dimensional accuracy across long runs. For production-focused shops the result is fewer index changes and more uptime; the insert therefore supports continuous to light interrupted cutting without frequent tool replacement. Where repeatability and consistent part quality matter, this material and grade deliver measurable process stability.

Geometry and clamping designed for repeatable accuracy

With a 0.4 mm corner radius and a 60° triangular geometry, the insert offers a controlled contact area that influences both surface finish and edge strength. The 0.4 mm radius softens the cutting edge to resist chipping while still allowing fine profile work; the triangular form ensures three usable edges per side when indexable. The cylindrical locating hole and a plate thickness of 4.76 mm contribute to secure seating in compatible toolholders, reducing vibration and runout. These geometric parameters combine to facilitate reproducible results on production lathes and driven tools.

Controlled chip formation for safe, efficient turning

The double-sided chipbreaker is engineered to manage chip flow in medium-steel turning, promoting short, controllable chips that evacuate reliably from the cutting zone. This reduces the risk of chip entanglement and improves coolant access to the cutting edge, which in turn aids thermal control and tool life. By selecting the correct chipbreaker and insert orientation in the toolholder, machinists can avoid secondary operations for chip trimming and keep cycle times consistent — a direct contribution to process efficiency.

ISO compatibility and straightforward system integration

As an ISO-format insert, compatibility is determined by form, relief angle, tolerance class, fastening, size and thickness; the TNMG160404 fits into standard TNMG toolholders when these parameters match. Typical system components include the indexable insert, a matching external holder or boring bar, a shim/clamping set and replacement screws. The plate’s designation and thickness allow easy replacement within established tooling systems, simplifying stocking and planning. For users requiring rapid integration, the ISO standardisation reduces setup uncertainty and shortens time to production.

FAQ

What materials is this insert best suited for?
The TNMG160404 T9215 indexable turning insert (Tungaloy) is primarily intended for medium steel; the T9215 grade balances wear resistance and toughness for continuous to light interrupted turning operations.

Can the insert handle interrupted cuts?
Yes — the carbide substrate combined with the T9215 coating and robust geometry allows the insert to perform well in continuous and light interrupted cuts, though heavy interruptions may require a different grade or edge preparation.

How does the 0.4 mm corner radius affect results?
A 0.4 mm corner radius increases edge strength and reduces the tendency to chip, producing more consistent surface finishes while slightly influencing cutting forces compared with smaller radii.

Is the insert reversible and how many cutting edges are available?
The triangular TNMG form provides multiple usable edges; with a double-sided plate and correct indexing it is possible to use several edges before replacement, improving cost-efficiency per insert.

Which holders are compatible with this TNMG insert?
Compatibility depends on matching the insert form, free angle (0°), tolerance class, fastening and thickness; standard TNMG holders that accept a 16-size, 4.76 mm thick, cylindrical-hole triangular plate are suitable.
