• 0.4 mm corner radius for controlled chamfers
• 7° clearance angle, with locating hole

Productivity gains through a wear‑resistant cutting grade

The combination of a CVD‑coated surface and a wear‑resistant carbide substrate in grade T9215 ensures sustained cutting performance when machining steel. This specification is the logical choice for operations that demand a balance between tool life and machining speed; the coating reduces abrasive wear while the substrate maintains fracture toughness, lowering the incidence of unexpected edge failure. For production environments, the result is fewer tool changes and a steadier part flow, contributing directly to overall manufacturing efficiency and predictable cycle times.

Geometry engineered for reliable cutting and finish

The insert’s triangular form with an included angle of 60°, a 0.4 mm corner radius and 7° clearance provides a predictable cutting geometry that supports stable chip formation and consistent surface quality. The 3.18 mm plate thickness and an inscribed circle of 11 mm provide rigidity in the seat, helping to prevent chatter when used with a correctly matched holder. The cylindrical hole with a single‑side countersink (40°–60°) enables standard clamping arrangements; compatibility with a given toolholder depends on form, relief angle and tolerance class, so selection of the appropriate holder is crucial for transferring the insert’s performance into repeatable part quality.

Practical application advice and selection logic

Designed primarily for turning applications on steel, this insert is appropriate for both external and internal operations when paired with a suitable holder or boring bar. The single‑sided chipbreaker and the grade’s resistance characteristics make it well suited to continuous and slightly interrupted cuts typical in bar‑feeding or semi‑finishing cycles. When specifying tooling, choose the chipbreaker and grade to match the workpiece material and stability of the setup; a stiffer assembly and optimal cutting data will unlock the grade’s productivity advantage and extend effective tool life. For mixed material shops that handle a variety of steels, this insert offers a reliable baseline for standard turning tasks.

FAQ

What materials is this insert designed for?
The TCMT110304 T9215 insert is specified for machining steel, where its CVD‑coated carbide construction provides the necessary wear resistance and toughness for mid‑range turning operations.

How is the insert clamped and what hole style does it use?
Clamping is achieved via a central cylindrical locating hole with a single‑side countersink (40°–60°); the seating geometry suits standard ISO triangular indexable holders when matched for form and tolerance.

Which cutting conditions favour this grade?
Grade T9215 performs best in continuous to lightly interrupted cuts at moderate to high speeds for steel; optimise feed and depth of cut in line with holder rigidity to prolong tool life.

Can the insert be used for internal boring?
Yes, the insert is suitable for internal turning when fitted to an appropriate boring bar designed for ISO triangular inserts and the machining setup provides adequate rigidity.

How does the 0.4 mm corner radius affect surface finish?
The 0.4 mm radius offers a controlled chamfer that balances edge strength with the ability to achieve consistent surface finish; it reduces the risk of edge chipping compared with smaller radii while maintaining acceptable part geometries.
