TCMT 090204 AH725 — TCMT turning insert (60°) by Tungaloy

TCMT 090204 AH725 is an ISO‑standard triangular turning insert for external and internal turning, offering a universal, breakage‑resistant grade suited to mixed‑material production.

PVD-coated AH725 universal grade
Suitable for steel and stainless steels
Triangle form TCMT, 60° geometry
Cylindrical hole with single-sided countersink

Consistent process security with a universal PVD grade

The AH725 grade is a PVD‑coated carbide designed for a broad range of steels and stainless steels, delivering stable chip formation and reliable edge life. This universality reduces the need for frequent insert changes when batches contain varying materials, improving uptime and cutting predictability. The coating enhances wear resistance under typical turning speeds, meaning more parts produced before index change is required, which contributes directly to process efficiency.

Geometry engineered for repeatable accuracy and surface quality

The triangular TCMT form with a 60° included angle and a corner radius of 0.4 mm offers a balance between strength and finish capability. The 7° clearance reduces rubbing while maintaining contact stability, and the 2.38 mm thickness gives secure clamping in standard holders. These geometric factors support repeatable dimensional results and predictable tool life, helping to meet tight tolerances on turned components without compromising cycle time.

Practical system setup for fast changeover and compatibility

The insert is supplied in the ISO format and requires a compatible outside holder or boring bar; compatibility depends on form, clearance, tolerance class, fastening method, size and thickness. The cylindrical hole with a single‑sided countersink (40°–60°) simplifies secure fastening and correct seating, aiding quick index changes. The one‑sided chipbreaker is suitable for general turning tasks, while the PVD coating helps maintain edge integrity under varying cutting conditions. For production settings that demand stability across small‑tool operations, this combination supports both productivity and reproducibility.

FAQ

What materials is this insert suitable for?
The AH725 grade is engineered for a wide range of steel and stainless steels, providing reliable chip control and wear resistance for mixed‑material turning tasks.

How does the PVD coating benefit cutting performance?
The PVD coating on this carbide insert improves hardness and wear resistance at the cutting edge, extending tool life and maintaining dimensional stability under typical turning conditions.

Which geometry details are critical for holder selection?
Select a holder compatible with the TCMT 090204 geometry: triangular seat, 60° included angle, 2.38 mm thickness and the cylindrical hole with single‑sided countersink to ensure correct clamping and seating.

What does the 0.4 mm corner radius mean for surface finish?
A 0.4 mm corner radius balances strength and finish capability; it supports moderate cutting depths while improving surface integrity compared with larger radii.

Is this insert suitable for small‑tool operations and high process security demands?
Yes, the universal, breakage‑resistant AH725 grade is particularly suited to smaller tools and applications where consistent process security is required
