CCMT09T312 AH6235 Tungaloy indexable insert — PVD-coated carbide, 1.2 mm nose radius

The CCMT09T312 AH6235 Tungaloy insert is a rhombic ISO turning insert designed for external and internal turning operations, optimised for stainless steels and interrupted cuts.

• PVD-coated carbide AH6235 for stainless steels
• 1.2 mm nose radius for accurate profiles
• Single-sided chipbreaker for interrupted cuts
• Central hole with 40°–60° countersink for secure clamping

Stable machining and improved edge life with a PVD-coated grade

The combination of a PVD-coated surface and the AH6235 carbide matrix provides enhanced edge stability and wear resistance when machining stainless steels and other demanding alloys. The coating reduces built-up edge and improves heat resistance, which translates directly into longer tool life and fewer insert changes per shift. As an ISO-design insert, compatibility with holders depends on shape, clearance, tolerance class, fastening method, size and thickness; this standardisation helps maintain consistent process parameters and repeatable results across production batches.

Secure clamping and geometry that supports productivity

The rhombic plate form with an 80° included angle, central hole and a cylindrical hole plus one-sided countersink (40°–60°) ensures a secure and repeatable clamping interface. The plate thickness of 3.97 mm and the 1.2 mm nose radius balance robustness with profile accuracy: the nose radius increases edge strength for interrupted cuts while still allowing fine surface finishes when set-up and feeds are adjusted accordingly. The single-sided chipbreaker is optimised for chip control under varying stability conditions, reducing chatter risk and contributing to a smoother production flow.

Measurable process benefits and recommended applications

Selecting the AH6235 grade with this insert typically improves process security on jobs involving interrupted cuts, work-hardening stainless alloys or operations with an increased risk of chipping. The insert is intended for both external and internal turning and is best used with a matched holder, shim and clamp set; a complete system comprising insert, compatible external holder or boring bar, underlay/clamp set and spare screws achieves the most reliable results. By choosing the correct chipbreaker and grade for the workpiece material and machining stability, the productivity gains become quantifiable through reduced downtime and fewer insert replacements.

FAQ

What materials is this insert best suited for?
The CCMT09T312 AH6235 Tungaloy insert is optimised for stainless steels and similar alloys, and it performs well in interrupted cutting conditions thanks to the tougher AH6235 grade.

How does the plate geometry support stable clamping?
The rhombic plate form with a central cylindrical hole and a 40°–60° countersink on the CCMT09T312 ensures secure, repeatable clamping and helps to reduce vibration during machining.

Which nose radius should be expected and what does it deliver?
The insert features a 1.2 mm nose radius, providing a compromise between edge strength for interrupted cuts and the ability to produce accurate profiles and acceptable surface finishes.

Can this insert be used for internal turning operations?
Yes — the ISO format and geometry of the plate make it suitable for both external and internal turning when paired with the appropriate boring bar or holder.

How should the chipbreaker selection be approached?
Choose the chipbreaker to match the workpiece material, cutting mode and machine stability; the CCMT09T312 comes with a single-sided chipbreaker designed to manage chips effectively in less-stable or interrupted-cut scenarios.
