TCMT 16T312 T9215 Tungaloy — Turning insert, CVD-coated carbide, 1.2 mm radius

The TCMT16T312 T9215 is a triangular ISO turning insert intended for external and internal turning, combining a CVD-coated carbide substrate with a 1.2 mm corner radius for robust, repeatable performance.

• CVD-coated carbide T9215
• 1.2 mm corner radius
• Triangle 16 mm plate size
• 7° relief angle for positive cutting

Improved throughput through stable cutting edge life

The CVD-coated T9215 grade is designed for medium steel machining and combines wear resistance with fracture toughness, which translates directly into longer tool life and fewer insert changes. The coating reduces flank wear under continuous and slightly interrupted cuts, so throughput increases without sacrificing surface integrity. This results in more predictable production cycles and reduced machine downtime, making the grade well suited to medium-volume turning operations.

Predictable chip formation and surface quality

A single-sided chipbreaker geometry paired with the 1.2 mm corner radius promotes controlled chip formation and evacuation, reducing the risk of built-up edge and improving finish on turned components. In practical terms, this means cleaner part surfaces and fewer rework steps when turning common steels. The 60° included angle of the triangular insert provides stable support in the pocket, helping to maintain cutting-edge integrity under higher feed rates.

Compatibility and simple integration into ISO tool systems

The insert follows ISO dimensions and fits compatible external holders or boring bars; compatibility depends on form, relief angle, tolerance class, fastening, size and thickness. The plate has a cylindrical hole with a one-sided countersink (40°–60°) for secure clamping, and a thickness of 3.97 mm that matches standard ISO pockets. These standardised interfaces enable straightforward replacement and reduce set-up complexity when switching inserts during production.

Practical choice for process reliability and productivity

Selecting this triangular insert yields a balance between productivity and operational safety: the CVD coating enhances wear resistance while the substrate resists chipping in continuous to mildly interrupted cuts. For shops aiming to improve cycle times on steel components, the combination of coating, grade and geometry supports stable cutting forces and repeatable part tolerances, so fewer tool trials are needed to reach process stability.

FAQ

What materials is this insert best suited for?
The TCMT16T312 T9215 insert is optimised for medium steel machining; the CVD-coated carbide and chipbreaker are tuned for stability and wear resistance in steel turning.

How does the 1.2 mm corner radius affect performance?
A 1.2 mm corner radius improves edge strength and surface finish under standard feeds, offering greater resistance to chipping compared with smaller radii during turning operations.

Is the insert compatible with standard ISO holders?
Compatibility depends on holder form, relief angle, tolerance class, fastening and size; the TCMT16T312 conforms to ISO dimensions and uses a cylindrical hole with countersink for secure clamping.

Can this insert handle interrupted cuts?
The substrate toughness and coating combination make the insert suitable for continuous to slightly interrupted cuts, providing a balance of wear resistance and fracture toughness.

Which SKU should be quoted when ordering?
Please reference SKU 6774028-Tungaloy or manufacturer SKU TUN6774028 when enquiring about this triangular turning insert.
