CPMT 090304 AH6235 ISO turning insert for stainless steel — Tungaloy

CPMT 090304 AH6235 is an ISO-format indexable turning insert suited to external and internal turning, particularly for stainless steels and interrupted cuts.

• ISO rhombic insert CPMT 090304
• PVD-coated carbide grade AH6235
• Designed for stainless steel and interrupted cuts
• 0.4 mm corner radius, 11° relief angle

Consistent cutting with a tougher PVD-coated grade

The PVD-coated AH6235 carbide delivers a balance of toughness and wear resistance that is tailored for machining stainless steel and operations with interrupted cuts. The PVD coating improves adhesion and thermal stability at the cutting edge, reducing crater wear and extending usable life compared with uncoated grades. For process planners, this means fewer insert changes and more predictable tool life under variable cutting loads, which supports higher machine utilisation.

Secure seating and repeatability for reliable setups

Built to ISO dimensions, the CPMT 090304 format ensures compatibility with a wide range of external holders and boring bars; fit depends on form, relief angle and tolerance class. The rhombic geometry and cylindrical hole with single-sided countersink (40°–60°) provide precise location and repeatable clamping, while the 3.18 mm plate thickness and 11° relief angle contribute to stable cutting conditions. Clear standardisation of locating features reduces set-up time and minimises indexing errors in serial production.

Edge strength and chip control that maintain surface quality

A 0.4 mm corner radius enhances edge resistance to chipping and improves robustness during interrupted cuts, while the single-sided chipbreaker is designed to guide chips away from the component and the toolpath. The result is consistent surface finish and fewer workpiece rejections in short-chipping alloys. The combination of geometry and grade supports both finishing passes and light roughing where controlled chip flow and edge security are priorities, helping to increase throughput with stable results.

FAQ

What materials is this insert suitable for?
The AH6235 PVD-coated carbide is formulated for stainless steel machining and performs well in interrupted cuts and situations with increased breakout risk.

How does the insert locate in a holder?
The rhombic CPMT 090304 format uses a cylindrical hole with a single-sided countersink; this provides precise seating and repeatable clamping in compatible ISO holders.

What benefits does the 0.4 mm corner radius provide?
A 0.4 mm radius increases edge strength and reduces the likelihood of chipping during interrupted cuts, improving process stability and surface quality.

Is this insert suitable for internal and external turning?
Yes, the ISO rhombic design and standard dimensions allow use in both external holders and suitable bore bars for internal turning operations.

Which chip control features are included?
The insert is equipped with a single-sided chipbreaker to promote controlled chip flow and prevent accumulation near the cutting zone.
