TCMT 16T304 T9225 turning insert — Tungaloy (ISO 16T304)

The TCMT16T304 T9225 is an ISO indexable turning insert designed for medium-to-heavy turning operations, offering a robust CVD-coated carbide grade for variable engagement conditions.

• CVD-coated carbide grade T9225
• Triangle ISO format TCMT 16T304
• 0.4 mm corner radius for sturdy cutting
• Cylindrical hole with single-side countersink

Longer cutting life through tougher coating and grade

The CVD-coated carbide in this grade delivers a balance of hardness and toughness that suits mixed and interrupted turning operations. The chosen grade, T9225, is a universal option for steel machining where changing engagement or light interruptions demand increased fracture resistance. This results in fewer insert changes, more consistent cycle times and reduced tooling costs per part. For production environments, the combination of coating and substrate translates directly into improved process reliability and predictable replacement intervals.

Secure seating and repeatable positioning for accurate parts

An ISO triangular format with a defined geometry guarantees secure clamping in compatible external holders or boring bars. The insert’s 7° relief angle and a thickness of 3.97 mm provide the necessary stiffness for heavier cuts, while the cylindrical hole with a single-side countersink (40°–60°) ensures correct orientation and simple fastening. Compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness; using the correct holder, shim and clamp set maintains repeatable positioning and dimensional stability across long production runs.

Effective chip control and surface quality with optimised geometry

The single-sided chipbreaker reduces the risk of long, entangling chips and helps maintain a stable cutting zone, which benefits surface finish and machine uptime. Selecting the appropriate chipformer and grade for the workpiece material and machining parameters improves evacuation and lowers the likelihood of secondary operations. For turning tasks in steel, this geometry supports sustained cutting parameters and contributes to consistent results in batch production, shortening cycle times and lowering scrap rates.
