TCMT090204 T9215 turning insert by Tungaloy — CVD-coated carbide, triangular, 7° clearance

TCMT090204 T9215 is an ISO-standard triangular turning insert designed for medium-steel turning applications where productivity and tool life must be balanced.

*ISO-compatible triangular insert
*CVD-coated carbide grade T9215
*7° clearance for reliable cutting
*0.4 mm nose radius for precision

Consistent productivity for medium-steel turning

The CVD-coated T9215 grade combines high wear resistance with good fracture toughness, making it a dependable choice for continuous to slightly interrupted cuts in medium-strength steels. The coating reduces flank wear and extends tool life, which lowers process costs per component and maintains output in series production. Specified as a cutting solution for turning, the insert supports higher cutting parameters while preserving dimensional repeatability.

Accurate geometry and assured holder compatibility

Designed to the ISO insert standard, the triangular form ensures straightforward interchangeability with ISO-compatible external holders and boring bars. Compatibility is governed by the insert’s form, clearance angle and tolerance class as well as its fixation and thickness; this insert features a 7° clearance and a 60° insert angle, supporting secure clamping and consistent seating. The pre-drilled hole with a cylindrical bore and a single-sided countersink (40°–60°) provides reliable locating and torque distribution during clamping.

Better chip control and surface quality

A one-sided chipbreaker is integrated to favour controlled chip formation when machining steels, improving evacuation and reducing re-cutting of chips in stable setups. The controlled chip flow contributes to a more consistent surface finish and minimises built-up edge tendencies at higher feed rates. Selecting the correct chipbreaker and the T9215 grade relative to workpiece stability will deliver the desired balance between productivity and surface integrity.

Practical system assembly and handling benefits

The insert is part of a complete system comprising the ISO turning insert, a matching external holder or boring bar, shim/clamp set and replacement screws. The plate thickness is 2.38 mm, with a nominal size designation of 09 and a 0.4 mm corner radius, allowing fine-profile turning and small-radius detail work. The combination of triangular shape, standardised dimensions and the CVD-coated carbide substrate enables quick changes, predictable tool performance and straightforward inventory management.

FAQ

What materials is this insert suited for?
The TCMT090204 T9215 insert is optimised for medium-steel machining; the T9215 grade pairs wear resistance with toughness for productive steel turning.

How does the insert fix to the holder?
The insert uses a central cylindrical hole with a single-sided countersink (40°–60°) to seat securely in ISO-compatible holders and ensure consistent clamping.

What chip control can be expected?
With its one-sided chipbreaker, the insert promotes predictable chip formation for improved evacuation and a better surface finish in stable turning operations.

Can this insert handle interrupted cuts?
Yes — the T9215 grade provides sufficient fracture resistance for continuous to slightly interrupted cuts, but very heavy interruptions may require a different geometry or grade.

Which parameters determine holder compatibility?
Compatibility depends on the insert’s form, clearance angle, tolerance class, fixation method, size and thickness; the TCMT090204 follows ISO standards for straightforward matching.
