CCMT 09T304 AH6235 – ISO indexable turning insert for stainless-steel turning (Tungaloy)

The CCMT09T304 AH6235 is an ISO-standard indexable insert designed for external and internal turning, optimised for machining rostfreie Stähle and interrupted cuts while offering improved resistance to edge breakouts.

• PVD-coated carbide grade AH6235
• Optimised for rostfreie Stähle and interrupted cuts
• 0.4 mm nose radius for precise profiling
• ISO CCMT rhombic geometry, 7° clearance

Consistent edge security for difficult stainless-steel work

The combination of a PVD coating with a tougher carbide composition provides greater resistance against built-up edge and chipping when turning stainless steels. The AH6235 grade is formulated for applications with elevated breakout risk and for interrupted cuts; this results in fewer unscheduled tool changes and more predictable component quality. By choosing a PVD-coated carbide insert, machinists gain a balance between wear resistance and edge toughness that supports consistent cycle-times in series production.

Geometry and clamping that simplify setup and accuracy

The rhombic CCMT geometry and the ISO-standard size ensure compatibility with a wide range of indexable holders; fit is determined by shape, relief angle, tolerance class, fastening and thickness. The insert features a 0.4 mm nose radius for fine profiling and an overall approach angle of 80°, enabling accurate external profiling and stable face turning. The insert is supplied with a cylindrical hole and a one-sided countersink (40°–60°) which supports secure clamping and repeatable indexing without complex fixture changes.

Productivity through targeted chip control and cutting strategy

A single-sided chipbreaker tuned to the grade provides controlled chip formation for typical turning operations, reducing the risk of entangling chips and improving surface finish expectations. With a plate thickness of 3.97 mm and a 7° clearance, the insert supports moderate depths of cut and good stability in conventional turning. Selecting the correct chipbreaker and matching feed/speed to the grade permits longer tool life and a higher first-pass yield, contributing directly to lower unit manufacturing costs over time.

Practical selection and system considerations

The ISO insert is part of a system that includes the matching external holder or boring bar, underlay/locating set and spare screws; compatibility must be checked by form, free angle, tolerance class, fastening, size and thickness. When retrofitting or replacing inserts, confirm the holder’s seat and screw type to ensure correct clamping. For interrupted cuts, prefer the AH6235 grade to reduce chipping, and adjust cutting parameters to account for workpiece material condition and fixture rigidity.

FAQ

Is this insert suitable for rostfreie Stähle?
Yes. The CCMT09T304 AH6235 insert is formulated specifically for rostfreie Stähle and applications with increased breakout risk, offering improved edge toughness.

Which holders are compatible with this CCMT insert?
Compatibility depends on holder form, free angle, tolerance class, fastening, size and thickness; the CCMT rhombic geometry matches standard CCMT holders when those parameters are aligned.

What is the recommended edge radius for fine finishing?
The insert has a 0.4 mm nose radius, which supports accurate profiling and a fine surface finish in both external and internal turning.

How does the AH6235 grade affect cutting strategy?
AH6235 provides tougher performance for interrupted cuts and stainless-steel machining; feed and speed should be adjusted to balance wear resistance and edge strength for longer tool life.

How is the insert clamped and indexed?
The insert uses a cylindrical hole with a one-sided countersink (40°–60°) for secure clamping and repeatable indexing when combined with the appropriate holder and clamping screw.
