SCMT 09T304 AH6225 – ISO turning insert, PVD-coated carbide, for turning (Tungaloy)

SCMT09T304 AH6225 is an ISO-standard square turning insert designed for external and internal turning applications, optimised for working with stainless steels and medium-precision finishing.

• PVD-coated cemented carbide AH6225
• Optimised for stainless steels
• Square 90° geometry, 0.4 mm radius
• Cylindrical hole with 40°–60° countersink

Consistent metal‑cutting performance for medium machining

The PVD-coated cemented carbide grade AH6225 delivers a balance between a sharp and a stable cutting edge, which is beneficial in mixed production runs and varying stainless materials. The coating increases wear resistance and helps maintain edge integrity under intermittent cutting conditions. Compatibility with ISO holders is determined by the insert's form, clearance angle and thickness, so the insert integrates into established tool systems without requiring special adapters. This results in fewer tool changes and more predictable cycle times in turning operations.

Robust geometry and secure clamping for repeatable results

The square plate with 90° lead angle and a 0.4 mm corner radius provides an effective compromise between edge strength and surface finish. A 7° clearance angle reduces rubbing and heat build-up at the flank, while the single-sided chipbreaker controls chip formation for typical turning feeds. The cylindrical hole with a one-sided countersink (40°–60°) is made for secure clamping with standard screws and shims; precise fixation reduces vibration and improves surface integrity. The plate thickness of 3.97 mm and ISO size 09 are matched to common external and internal toolholders.

Operational advantages that lower total machining cost

Using a grade tailored to stainless applications minimises frequent edge failures often caused by built-up edge and work-hardening. The AH6225 grade is designed for steady chip formation and consistent tool life in medium-duty turning, meaning less downtime for insert replacement. Insert compatibility within the ISO system allows rapid replenishment: a matching holder, shim and screw complete the system. Clear technical specifications and repeatable performance support process stability and predictable maintenance planning on the shop floor.

FAQ

Is this insert suitable for stainless steels?
Yes. The SCMT09T304 AH6225 insert is formulated and coated for turning stainless steels and provides a balance of sharpness and edge stability suitable for medium machining.

Which holder features are required for correct fitment?
Compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and thickness; the insert fits standard ISO square holders when these parameters match the SCMT09T304 dimensions.

What is the purpose of the 0.4 mm corner radius?
The 0.4 mm radius increases edge strength compared with a sharp corner, improving resistance to chipping while still allowing satisfactory surface finish in light to medium turning.

How does the PVD coating affect tool life?
The PVD coating on the AH6225 grade improves wear resistance and helps maintain a stable cutting edge under changing conditions, which generally extends effective tool life compared with uncoated grades.
