TCMT 16T304 T9215 Turning Insert by Tungaloy — CVD-coated carbide, 60° triangle

A TCMT 16T304 T9215 indexable turning insert designed for external and internal turning in medium steel machining, combining wear resistance with fracture toughness for sustained productivity

• CVD-coated carbide grade T9215
• 60° triangular geometry for versatile turning
• 0.4 mm nose radius for fine profile control
• With hole and 40°–60° countersink for positive clamping

Sustained productivity for medium steel applications

The CVD-coated carbide composition of this insert, identified by grade T9215, is formulated to balance wear resistance with fracture toughness, making it a dependable choice for continuous and slightly interrupted cuts. This material pairing reduces flank wear and extends tool life, which in turn lowers tool-change frequency and supports higher part output. The clear benefit is improved process economy: fewer stoppages and more consistent component dimensions during batch and single-piece turning.

Precise geometry for consistent clamping and finish

Manufactured to the ISO series specification, the triangular insert features a 60° cutting angle, a 0.4 mm nose radius and a plate thickness of 3.97 mm, ensuring geometric repeatability in standard toolholders. The insert is supplied with a hole and a single-sided countersink (40°–60°) to secure a stable clamping interface, while the specified 7° relief angle helps control cutting forces and surface integrity. These attributes translate into reliable seating in matched holders and improved surface finish on turned parts, reducing rework requirements.

System compatibility and application guidance

The indexable plate integrates into a standard turning system consisting of the insert, a suitable external holder or boring bar, a support shim/clamping set and replacement screws. Selection of the single-sided chipbreaker and the T9215 grade should be matched to workpiece material, machining type and machine stability to exploit the insert’s potential fully. For external and internal turning tasks on medium-steel components, this solution offers a pragmatic balance of productivity and robustness while simplifying tool management across varied turning operations.

FAQ

Is this insert suitable for internal boring as well as external turning?
Yes. The TCMT 16T304 T9215 turning insert is specified for both external and internal turning and can be used in compatible boring bars or external holders, provided holder geometry and clamping meet ISO standards.

Which materials are best machined with this grade?
Grade T9215 is intended as a first choice for medium steel machining, offering a good balance of wear resistance and fracture toughness for continuous to slightly interrupted cuts.

How does the insert secure to the holder?
The plate is supplied with a hole and a single-sided countersink (40°–60°) to enable positive clamping; secure seating depends on matching the holder’s form, tolerance class, fastening and plate thickness.

What chip control can be expected from this insert?
The single-sided chipbreaker has been designed for controlled chip formation in medium-steel turning; matching the chipbreaker to workpiece and machining conditions improves evacuation and surface quality.

Are replacement screws and shims required for mounting?
Yes. Proper assembly requires the matching shim/clamping set and replacement screws to ensure repeatable clamping and to exploit the insert’s ISO compatibility.
