TCMT110308 T9215 Turning Insert (CVD-coated Carbide) – Tungaloy

The TCMT110308 T9215 is an ISO triangle turning insert designed for external and internal turning on medium steels, offering a balance of productivity and edge stability.

• CVD-coated carbide grade T9215 for steel machining
• ISO TCMT110308 triangle insert, 7° relief angle
• 0.8 mm corner radius for robust edge strength
• Countersunk hole fit with 40°–60° seating, 3.18 mm thickness

Consistent machining through advanced CVD coating and grade selection

The combination of CVD-coated carbide and the T9215 grade provides a predictable balance between wear resistance and toughness, making the insert a dependable choice for continuous to lightly interrupted cuts in medium steels. CVD coating creates a ceramic barrier on the carbide substrate that reduces abrasive wear and improves thermal stability; this translates into longer interval times between indexings and more consistent part quality. The controlled substrate toughness helps to resist chipping, so machining processes remain stable even under variable cutting conditions, supporting higher overall output.

Stable seating and geometry for repeatable tool performance

Conformance to ISO geometry and the 7° relief angle ensure reliable clearance and chip flow when paired with suitable holders. The insert’s 3.18 mm thickness and triangular form provide a secure clamping surface, while the cylindrical hole with a single-sided countersink (40°–60°) guarantees correct seating and torque transmission. The 60° included angle of the triangle contributes to stiffness in the cutting zone, reducing vibration and improving surface finish. Correct holder selection is decisive: compatibility depends on holder form, tolerance class, fastening method, size and thickness, so the insert should be matched to the clamping system for optimal results.

Durable edge and efficient chip control for productive turning

A 0.8 mm corner radius gives the cutting edge extra reinforcement for rougher passes and intermittent engagements, reducing the likelihood of premature edge failure. The single-sided chipbreaker channel is designed to control chip formation for a wide range of turning operations, helping to avoid entanglement and to ease evacuation. Together, these features support higher feed rates and sustained cutting conditions, improving productivity while maintaining surface quality. The insert is intended to be used as part of a system—insert, external holder or boring bar, shim/seat and fastening hardware—to enable fast replacements and minimal setup time.

FAQ

What materials is this insert best suited for?
The TCMT110308 turning insert in grade T9215 is optimised for medium steel machining; the CVD-coated carbide construction delivers the wear resistance and toughness required for productive steel turning.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius increases edge strength and chip load capacity, which helps the TCMT110308 insert withstand rougher passes and light interruptions while maintaining surface quality.

Which holder features are required for secure clamping?
Secure clamping requires a holder that matches the ISO triangle form, accepts the 11 mm size and 3.18 mm thickness, and accommodates the cylindrical hole with a single-sided countersink as specified for correct seating.

What operational benefits does the T9215 grade offer?
T9215 provides a balance of high wear resistance and fracture toughness, enabling sustained cutting at higher productivity for continuous to lightly interrupted turning operations.
