TPMT 090204 AH6235 Turning Insert — PVD-coated, 0.4 mm Radius (Tungaloy)

The TPMT090204 AH6235 is an ISO triangular turning insert optimised for external and internal turning, particularly effective for interrupted cuts and machining stainless steel.

• ISO triangular insert TPMT 090204
• PVD-coated AH6235 for stainless steel
• 11° clearance and 0.4 mm corner radius
• Central hole with cylindrical + countersink

Reliable edge performance for stainless machining

The insert combines a PVD-coated surface with a cemented carbide substrate to deliver enhanced resistance to chipping when machining stainless steel. The AH6235 grade is formulated as a tougher cutting grade suited to interrupted cuts and unstable cutting conditions; this reduces unplanned edge failures and helps maintain consistent component tolerances. Selecting a tougher grade mitigates built-up edge and improves process stability during medium-duty turning operations.

Precision geometry that ensures predictable results

The ISO triangular insert geometry with a 60° included angle and a 0.4 mm corner radius provides a balanced compromise between edge strength and surface finish. The 11° clearance (frewinkel) helps to reduce rubbing and heat generation at the flank, while the 2.38 mm plate thickness contributes to mechanical rigidity in the toolholder. For practical planning, compatibility depends on holder form, relief angle, tolerance class, fastening and insert size/thickness — check these parameters to ensure correct seating and repeatable indexing.

Practical chip control and secure mounting

Equipped with a one-sided chipbreaker, this insert promotes controlled chip formation on materials prone to long, stringy swarf. The central mounting hole is a cylindrical bore with a single-sided countersink (40°–60°), allowing secure clamping in a range of ISO-compatible holders and boring bars. This secure fixing reduces chatter and supports higher process reliability, meaning fewer interruptions and lower scrap rates in production runs.

FAQ

Is this insert suitable for stainless steel machining?
Yes. The AH6235 grade on the TPMT090204 insert is designed as a tougher, PVD-coated carbide for improved resistance to chipping when machining stainless steel.

Can the insert be used for interrupted cuts?
Yes. The toughness of the AH6235 grade makes the insert suitable for interrupted cuts and operations with elevated risk of edge breakout.

What toolholders are compatible with this insert?
Compatibility is determined by holder form, clearance angle, tolerance class, fastening method, insert size and thickness; the TPMT090204 fits ISO-compatible triangular holders with matching seating and clamping.

What are the key geometry parameters to check before fitting the insert?
Verify the 11° clearance, 60° included angle, 0.4 mm corner radius and the 2.38 mm plate thickness to ensure correct seating and expected cutting behaviour.

Is the hole style compatible with standard clamping systems?
The central cylindrical hole with single-sided countersink (40°–60°) provides a secure clamping solution for most ISO-style clamping systems.
