TCMT16T308 T9225 ISO turning insert for Turning by Tungaloy

TCMT16T308 T9225 is an ISO indexable insert engineered for medium-to-heavy steel turning, offering a triangle 60° geometry and a robust CVD-coated carbide grade for variable engagement and interrupted cuts.

• ISO triangle 60° geometry
• CVD-coated carbide grade T9225
• 0.8 mm nose radius for versatility
• With cylindrical hole + 40°–60° countersink

Engineered for productive medium-to-heavy steel turning

The CVD-coated carbide composition of this turning grade provides a balance between wear resistance and toughness, making it suitable for shifting engagement conditions. The T9225 grade is formulated as a robust universal grade, which translates into longer tool life and fewer insert changes when machining steel under mixed-cut or intermittently interrupted conditions. For production environments where stable chip formation and repeatable results matter, this insert reduces downtime and supports consistent cycle times.

Precision geometry for repeatable results and secure clamping

The triangle 60° geometry delivers four cutting edges per indexable insert and a compact cutting profile for external and internal turning operations. The 0.8 mm nose radius gives a compromise between edge strength and finish capability, while the 7° relief helps avoid rubbing on the flank face. Being ISO‑compliant, the insert integrates with standard toolholders; correct matching of holder form, relief angle, tolerance class, size and thickness is essential to ensure toolholder compatibility and reliable clamping during heavy cuts.

Chip control, clamping and handling that support faster throughput

A single-sided chipbreaker on the insert is designed to manage chip flow in typical turning operations, enhancing stability and surface quality in steel turning. The plate features a cylindrical hole + single-side countersink (40°–60°) to secure the insert accurately in the seat and permit safe indexing. With an inscribed circle 16 mm and 3.97 mm thickness, the geometry provides the rigidity required for medium-to-heavy cuts while keeping insert handling and replacement straightforward within a standard ISO tool system.

System perspective and recommended application practice

This insert is one element of a full cutting system: an ISO turning insert, an appropriate external holder or boring bar, a shim/clamp set and replacement screws. Selection of the correct chipbreaker and grade should be based on workpiece material, machine stability and the intended roughing versus finishing strategy. For variable engagement or intermittent cuts where toughness is required, the T9225 grade provides a sensible compromise between wear performance and fracture resistance. If further process data is required, technical consultation can clarify the best holder and cutting parameters for a given setup.

FAQ

Which materials is this insert intended for? This Tungaloy ISO turning insert, grade T9225, is intended primarily for steel machining and is formulated as a robust universal grade for medium-to-heavy steel turning.

How does the 0.8 mm nose radius affect surface finish and strength? A 0.8 mm radius increases edge strength and provides a balance between improved tool life and acceptable surface finish for general turning tasks when using the TCMT16T308 insert.

Is the insert compatible with standard ISO toolholders? Yes, the TCMT16T308 follows ISO geometry and is compatible with holders that match the form, relief angle, tolerance class, size and thickness specified for ISO triangle 16‑series inserts.

What benefit does the single-sided chipbreaker offer in practice? The single-sided chipbreaker improves chip control during turning operations and supports consistent chip flow, which helps maintain surface quality and process stability when cutting steel.

How should the insert be clamped to ensure reliable performance? Use a compatible external holder or boring bar with the correct shim/clamp set and replacement screws; the cylindrical hole with a single-side countersink ensures accurate seating and secure clamping for reliable performance.
