CCMT 09T304 AH6235 Turning Insert — PVD-coated carbide, 0.4 mm nose radius (Tungaloy)

The CCMT09T304 AH6235 is an ISO-standard rhombic indexable turning insert designed for external and internal turning applications, offering a tough PVD-coated carbide grade suited to interrupted cuts and materials prone to chipping.

• ISO rhombic insert CCMT 09T304, 0.4 mm nose radius
• PVD-coated carbide AH6235 for stainless steel
• Single-sided chipbreaker for interrupted cuts
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance for stainless-steel turning

The combination of a PVD-coated surface and the AH6235 carbide substrate delivers a balance between toughness and wear resistance that is particularly suitable for stainless-steel machining and operations with increased breakout risk. The coating reduces built-up edge and improves abrasion resistance, while the tougher substrate resists chipping in interrupted cuts. This results in more stable tool life and more predictable process windows, which supports higher productivity and fewer unscheduled insert changes.

Geometry and clamping for repeatable stability

The insert’s rhombic ISO shape with a 0.4 mm nose radius and a 7° clearance angle provides a compromise between finish and strength; the 3.97 mm plate thickness contributes to rigidity when clamped. A cylindrical mounting hole with a 40°–60° countersink ensures secure and repeatable seating in compatible holders, reducing micro-movement and vibration. These geometric details allow the insert to deliver consistent surface quality and dimensional repeatability in both external and internal turning.

Process integration and practical advantages

Equipped with a single-sided chipbreaker, the insert supports chip control in unstable cutting conditions and during interrupted cuts; pairing the chipbreaker style and grade to the workpiece material and machining stability is essential for optimal results. The system approach comprises the ISO insert, a matching external holder or boring bar, an appropriate shim/clamp set and replacement screws, which together ensure a reliable setup. For general-purpose turning, the combination of chip control and a robust grade simplifies process planning and improves uptime.

FAQ

What materials is this insert best suited for?
The CCMT09T304 AH6235 insert is optimised for stainless-steel and applications with an increased risk of chipping; the AH6235 grade provides toughness for interrupted cutting.

How does the insert secure to the toolholder?
The insert features a cylindrical hole with a 40°–60° countersink, designed for secure clamping in compatible external holders or boring bars to ensure repeatable seating.

Is the chip control suitable for unstable cuts?
Yes, the single-sided chipbreaker is intended to improve chip formation and evacuation in interrupted cuts and other unstable machining conditions.

Which system components are needed to use this insert?
A compatible ISO external holder or boring bar, the correct shim/clamp set and the replacement screws are required to assemble the cutting system for the insert.

What benefits does the PVD coating offer?
The PVD-coated surface enhances abrasion resistance and reduces built-up edge, contributing to improved tool life and more consistent surface finish when machining stainless-steel.
