TCMT 110308 T9215 indexable turning insert for ISO-format turning — Tungaloy

TCMT 110308 T9215 indexable insert for external and internal turning, designed for medium steel machining with a 60° triangular geometry and a 0.8 mm nose radius.

• CVD-coated cemented carbide grade T9215
• ISO TCMT 110308 format, 60° triangle
• 0.8 mm nose radius for reduced cutting forces
• Cylindrical hole with one-sided countersink 40°–60°

Reliable wear resistance for continuous to lightly interrupted turning

The TCMT 110308 insert combines a CVD-coated cemented carbide substrate with the T9215 grade to deliver an excellent balance of wear resistance and edge strength for medium-steel applications. The CVD coating improves resistance to abrasive wear and thermal effects, which supports longer, consistent tool life under steady cutting conditions. For production environments prioritising throughput, the coated carbide reduces the frequency of index changes and contributes to predictable cycle times and lower overall tooling costs.

Geometry engineered for stable machining and surface quality

The 60° triangular geometry and 0.8 mm nose radius give a stable cutting edge suitable for both finishing and light roughing in turning operations. The insert’s 7° clearance angle and a plate thickness of 3.18 mm ensure robust support in the pocket, reducing chatter and enabling better surface finishes. As an ISO-format insert, compatibility with holders depends on shape, clearance, tolerance class, fastening and thickness; matching these parameters preserves clamping integrity and repeatability across tool changes.

Practical benefits on the shop floor: productivity and process security

A single-sided chipbreaker paired with the T9215 grade helps to control chip formation when machining medium steels, improving evacuation and reducing interruptions. This combination supports higher metal-removal rates while maintaining edge stability, which is particularly useful in continuous or slightly interrupted cuts. The result is a lower cost per component through extended index life and reduced tool-change downtime, making the insert an efficient choice for small-batch to high-volume turning tasks.

System compatibility and selection advice for turning setups

The insert is supplied in the ISO indexable system context and is intended for use with a suitable external holder or boring bar, plus a matching underlay/clamping set and replacement screws where required. The plate’s cylindrical hole with one-sided countersink (40°–60°) enables secure fastening and precise seating. When selecting an insert variant, consider workpiece material, cutting parameters and machine stability; the T9215 grade is the recommended first choice for general medium-steel machining due to its balance of wear resistance and toughness.

FAQ

What materials is this insert best suited for?
The TCMT 110308 T9215 Tungaloy insert is optimised for medium steel machining; the T9215 grade offers a good balance of wear resistance and fracture toughness for continuous to lightly interrupted cuts.

Which geometry features improve surface finish and stability?
The 60° triangular geometry combined with a 0.8 mm nose radius and 7° clearance reduces cutting forces and improves support in the pocket, resulting in more stable cutting and improved surface quality.

How is the insert secured in a holder?
This ISO-format insert uses a cylindrical hole with a one-sided countersink (40°–60°) for positive clamping; compatibility requires matching insert form, thickness and tolerance class with the selected external holder or boring bar.

Is this insert suitable for interrupted cuts?
The T9215 grade provides sufficient toughness for light to moderate interruptions; for heavy interrupted cuts, assess machine stability and consider inserts with enhanced edge robustness.

Can the chipbreaker be used for a range of feed rates?
The single-sided chipbreaker on this insert supports controlled chip formation across typical turning feed ranges for medium steels, aiding evacuation and reducing the risk of built-up edge.
