TCMT 110204 T9215 turning insert for turning — Tungaloy

The TCMT110204 T9215 is an ISO triangular indexable insert engineered for external and internal turning in medium steel applications, offering a balance of wear resistance and fracture toughness.

• CVD-coated carbide for wear resistance
• Optimised for steel turning operations
• ISO triangular 11 mm, 60° geometry
• 0.4 mm nose radius, one-sided chipbreaker

High wear resistance that raises throughput

The CVD-coated carbide composition of this grade combines a hard, wear-resistant surface with a tough substrate to extend tool life under continuous and lightly interrupted cuts. The T9215 grade is specified for mid-range steel machining and is formulated to deliver stable chip formation and good resistance to flank and crater wear. This results in longer productive tool life, fewer insert changes and a lower cost per component when machining medium-strength steels. The combination of wear resistance and fracture toughness supports higher machining speeds and consistent surface quality in serial production.

Designed for reliable seating and simple integration

The insert conforms to ISO geometry and is supplied as a triangular 11 mm format with a 60° cutting angle, 2.38 mm thickness and a 7° clearance angle, ensuring compatibility with a broad range of standard holders. The holder compatibility depends on the insert’s form, clearance angle, tolerance class, attachment method, size and thickness; when these parameters match, the insert seats securely for repeatable accuracy. The insert is supplied with a hole (cylindrical hole with a single-sided countersink 40°–60°) to suit many clamping systems. For a complete system, pair the insert with an appropriate external holder or boring bar plus a shim/clamp kit and replacement screws to maintain clamping integrity and minimise downtime.

Geometry and chip control for consistent surface finish

The 0.4 mm nose radius offers a practical compromise between strength and surface finish, suitable for semi-finishing and general turning tasks. The one-sided chipbreaker is designed to direct and fragment chips reliably in stable setups, reducing the risk of entanglement and facilitating safe chip evacuation. When combined with the T9215 coating and carbide substrate, the insert performs well across continuous to slightly interrupted cuts, giving predictable tool behaviour and repeatable component tolerances. Choose the chipbreaker and grade to match material, feed and component stability for the best balance of productivity and finish.

Practical use and selection guidance

This insert is intended for turning applications and should be selected as part of a system that includes the correct holder geometry and clamping method. For medium steel, the T9215 grade is a first choice, while adjusting feed, speed and depth of cut according to machine rigidity will optimise tool life. The ISO triangular insert form offers three usable cutting edges when rotated, improving cost efficiency per edge. For best results, check holder compatibility for the 7° clearance angle, 11 mm size and 2.38 mm thickness before assembly; incorrect matching can compromise seating and repeatability.

FAQ

What materials is this insert best suited for?
The TCMT110204 T9215 insert is optimised for medium steel machining; the T9215 CVD coating and carbide substrate provide wear resistance and toughness suitable for this material class.

How can I ensure the insert fits my holder?
Compatibility is determined by insert form, 7° clearance angle, tolerance class, attachment style, 11 mm size and 2.38 mm thickness; match these parameters with the holder specification to ensure correct seating.

Is the insert suitable for interrupted cuts?
Yes, the grade is designed for continuous to lightly interrupted cuts; for heavy interruptions consider grades or geometries specified for higher impact resistance.

How many cutting edges are usable on the insert?
The triangular form provides three indexed cutting edges per insert, improving cost efficiency per edge when rotated correctly.

What is the function of the chipbreaker?
The one-sided chipbreaker promotes controlled chip fragmentation in stable setups, aiding evacuation and reducing the risk of chip entanglement during turning.
