TCMT 16T308 T9225 ISO turning indexable insert — 60° triangular, CVD-coated carbide by Tungaloy

TCMT 16T308 T9225 is an ISO-format indexable insert designed for turning operations, especially suited to medium–heavy steel machining and applications requiring toughness for interrupted cuts.

• CVD-coated carbide T9225
• Suitable for medium–heavy steel machining
• 60° triangular ISO geometry
• Cylindrical hole with 40°–60° countersink

Robust grade for variable steel conditions

The insert is furnished in T9225, a CVD-coated carbide grade optimised for a broad range of steel applications where a balance of toughness and wear resistance is required. This composition supports stable chip formation under changing engagement conditions and tolerates slight interruptions in the cut without premature edge chipping. The result is a consistent component finish and longer usable life per edge, which contributes to lower tool change frequency and improved process stability in batch and single-piece production alike.

Geometry and dimensions that aid reliability and access

Built to ISO form TCMT with a 60° triangle, the insert provides a compact footprint for versatile turning tasks while delivering robust cutting edges. The 0.8 mm corner radius helps to distribute cutting forces on the nose for greater edge strength, and the 7° relief angle reduces rubbing on the flank. The plate thickness of 3.97 mm and the cylindrical hole with a single-side countersink (40°–60°) ensure secure seating in standard clamping systems; compatibility with a holder depends on form, relief angle, tolerance class, fastening method, size and thickness, so correct matching to the clamping system is essential for optimum performance.

System integration and practical advantages in the workshop

As part of an ISO insert system, the item integrates with a matching outer holder or boring bar, plus a shim/clamp set and replacement screw. The single-sided chipbreaker geometry provides controlled chip flow for many turning tasks, reducing downtime caused by tangled chips and enabling safer automatic handling. For shops seeking predictable cycle times, the combination of a stable grade and defined geometry supports repeatable results and facilitates programming with established cutting data for medium–heavy steel machining.

Selection guidance and application notes

For external and internal turning, select the chipbreaker and grade based on workpiece material, machining strategy and machine stability. The CVD coating improves resistance to abrasive wear and helps maintain edge integrity in higher-temperature cuts, while the underlying carbide substrate ensures toughness. Where cutting conditions are highly interrupted or the setup is less rigid, the universal toughness of the T9225 grade reduces the risk of edge failure. For best results, pair the insert with a holder rated for ISO TCMT inserts and confirm seating geometry before production runs.
