TCMT 16T304 T9215 Indexable Turning Insert for Turning — Tungaloy

The TCMT16T304 T9215 is an ISO-standard triangular insert engineered for efficient external and internal turning of medium steels.

• CVD-coated carbide T9215 grade
• Optimised for medium steel machining
• 60° triangular insert with 0.4 mm radius
• Suitable for continuous to light interrupted cuts

Proven wear resistance for productive turning

The CVD-coated carbide substrate in grade T9215 combines high wear resistance with reliable fracture toughness, making it a rational choice for productive turning operations on medium steel. This composition reduces flank wear under sustained cutting and supports higher cutting speeds, which in turn lowers cycle times and increases throughput. Selection of this grade is particularly beneficial where consistent tool life is required across series production or extended batch runs, helping to reduce tool-change frequency and non-productive downtime.

Improved chip control and surface integrity

A single-sided chipbreaker paired with the 60° triangular geometry and a 0.4 mm corner radius offers controlled chip formation and favourable cutting forces for typical finishing and semi-finishing passes. Controlled chips prevent tangling and evacuation issues at the tool tip, resulting in steadier machining and improved surface quality. The result is fewer rework cycles, less operator intervention and a more predictable machining process for both external and internal turning tasks.

ISO compatibility for straightforward integration

As an ISO-standard insert, compatibility with holders is determined by form, clearance angle, tolerance class, fastening and size. The insert features a cylindrical hole with a one-sided countersink (40°–60°) to suit a wide range of clamping systems designed for TCMT-style inserts. This standardisation simplifies spare-part management on the shop floor and enables rapid integration into existing tool holders without requiring bespoke fixtures or adapters.

Cost-efficiency through optimised application

Using a grade developed for medium steel enables efficient material removal while maintaining tool life, which improves the cost-per-part calculation in high-volume or repeat production. The combination of continuous to light interrupted cut capability and robust coating technology supports higher metal-removal rates where machine stability permits. Over time, this translates into measurable savings in tooling expenditure and greater overall process reliability.

Secure clamping and practical dimensions

The insert's 3.97 mm thickness, triangular form and central hole design ensure secure clamping in compatible toolholders, reducing the risk of micro-movements that can degrade tolerances or surface finish. The specified 7° clearance angle contributes to lower friction and helps to avoid rubbing in applications with limited radial engagement, while the 16 mm inscribed circle provides a familiar size for common turning setups.

Application guidance and process selection

For best results, match the chipbreaker and grade to workpiece material, machining type and machine stability. The insert is optimised for medium steels and works well in continuous to slightly interrupted conditions; for more severe interruptions or highly alloyed materials, consider alternative geometries or tougher grades. Metav Werkzeuge offers practical advice on selecting the correct chipbreaker style and cutting data to support stable, economical machining.

FAQ

Which materials is this insert best suited for? The TCMT16T304 T9215 insert is designed primarily for medium steel machining; the T9215 grade balances wear resistance and toughness for this material group.

What are the key dimensions and geometry of the insert? The insert has a 16 mm inscribed circle, 3.97 mm thickness, 60° triangle geometry, 0.4 mm corner radius and a 7° clearance angle; it also features a cylindrical hole with a one-sided countersink (40°–60°).

How is holder compatibility determined? Compatibility with holders requires matching the insert form, clearance angle, tolerance class, fastening method, size and thickness; the ISO designation and central hole style support common TCMT-compatible clamping systems.

For which machining conditions is the T9215 grade recommended? Grade T9215 performs well in productive turning of medium steels, particularly under continuous to light interrupted cutting conditions where a balance of wear resistance and fracture resistance is needed.

What benefits does the chipbreaker provide? The single-sided chipbreaker promotes controlled chip formation and evacuation, improving surface finish and reducing the risk of chip interference during both external and internal turning.
