TCMT 090204 AH725 Tungaloy turning insert — PVD-coated carbide, 0.4 mm nose radius

TCMT090204 AH725 turning insert for external and internal turning, designed for stable chip formation and reliable performance where material mix and process security are priorities

• ISO TCMT 090204 geometry for universal holders
• PVD-coated carbide grade AH725 for steels
• 7° clearance angle for secure cutting action
• 0.4 mm nose radius for consistent surface finish

Consistent cutting performance from a robust carbide grade

The PVD-coated carbide in grade AH725 delivers a universal, chip-resistant solution tailored for turning applications on steel and stainless steel. The coating improves wear resistance and thermal stability, which stabilises tool life under mixed-material production. This grade is especially suitable where small cutters are used or where frequent changes in workpiece materials demand a forgiving and process-secure insert. The result is reduced downtime and steadier cycle times in batch and continuous turning operations.

Precision geometry for predictable results and simple holder matching

The insert follows the ISO TCMT 090204 format, so compatibility with toolholders is governed by form, clearance, tolerance class, fastening method, size and thickness. The 7° clearance and 60° included angle give a reliable cutting geometry that reduces rubbing and improves edge life. The single-sided chipbreaker supports consistent chip control in a broad range of turning conditions; select the chipbreaker and grade according to workpiece material and machining stability to maximise process reliability.

Practical advantages that improve surface finish and productivity

A 0.4 mm nose radius helps achieve a steady surface finish without demanding excessive cutting forces, while the 2.38 mm plate thickness and triangular form provide secure seating and repeatable orientation in the clamping assembly. The insert’s hole configuration — cylindrical hole with a single-side countersink (40°–60°) — ensures secure fixing and straightforward replacement of screws and clamping kits. These attributes translate into fewer interruptions and improved overall productivity for routine turning tasks.

FAQ

What materials is this insert suitable for?
The TCMT090204 AH725 insert is specified for turning steel and stainless steel, offering a universal, chip-resistant solution for mixed-material production.

How does the AH725 grade benefit production?
AH725’s PVD-coated carbide composition enhances wear resistance and process security, which helps extend tool life and stabilise machining when workpiece materials vary.

Which holders are compatible with this insert?
Compatibility follows standard ISO TCMT dimensions; match the holder by form, clearance angle, tolerance class, fastening type, size and plate thickness to ensure correct seating.

What is the effect of the 0.4 mm nose radius on surface finish?
A 0.4 mm nose radius provides a balance between surface finish and cutting forces, enabling consistent finish quality without excessive load on the cutting edge.

Does the insert require a special screw or clamping kit?
The insert uses a cylindrical hole with a single-side countersink (40°–60°); standard clamping sets and replacement screws for ISO TCMT inserts are applicable, provided they match the specified hole style and tolerance.
