CCMT 09T308 AH8005 ISO turning insert for turning — Tungaloy

The CCMT09T308 AH8005 is an ISO-standard rhombic turning insert designed for precision external and internal turning of heat‑resistant alloys and hard materials in stable setups

• PVD-coated carbide grade AH8005
• ISO rhombic insert CCMT 09 profile
• 0.8 mm corner radius for precision
• One-sided chipbreaker, hole with countersink

Longer tool life through optimised coating and substrate

The combination of a PVD-coated surface and a wear‑resistant carbide substrate in grade AH8005 extends tool life under elevated temperatures and abrasive conditions. The hard, thin coating reduces adhesion and diffusion wear, which leads to fewer insert changes and more productive cutting time. For shops machining heat‑resistant alloys, this translates into predictable tool performance and reduced downtime, as the coated substrate maintains edge integrity during prolonged cuts.

Precision geometry for consistent surface finish and repeatability

A rhombic ISO CCMT geometry with a 0.8 mm corner radius provides a balance between strength and finishing capability. The moderately small radius allows controlled cutting forces while still producing a fine surface texture on the workpiece. The insert’s relief angle of 7° and the included 80° approach geometry contribute to stable contact conditions at the cutting edge, which benefits repeatable part quality when paired with an appropriate holder and machine stiffness.

Secure clamping and chip control for efficient turning cycles

The insert is supplied with a hole and a cylindrical hole plus a single‑side countersink (40°–60°), enabling positive seating and secure clamping to the toolholder. The one‑sided chipbreaker is engineered to produce manageable chip forms in stable cutting conditions, lowering the risk of chip tangling and improving process reliability. Together, these features support efficient cycle times and safer unattended cycles in production environments.

Application guidance: choosing the right grade and setup

Designed for turning applications, this ISO‑series insert suits both external and internal operations when the workholding and machine rigidity match the cutting conditions. The AH8005 grade is particularly suited to hard or heat‑resistant materials under stable machining; selecting the correct chipbreaker and holder geometry is essential to fully exploit the insert’s potential. For mixed or unstable setups, opt for a more robust radius or adjust feeds and speeds to maintain cutting stability.

FAQ

What work materials is this insert suited to? The CCMT09T308 AH8005 Tungaloy insert is designed for heat‑resistant alloys and other hard materials; the AH8005 grade and PVD coating provide enhanced wear resistance for such applications.

Can this insert be used for internal turning? Yes, the rhombic CCMT geometry and secure hole clamping make the insert suitable for both external and internal turning when used with a compatible holder and stable setup.

What does the chipbreaker type mean for machining? A one‑sided chipbreaker on this insert produces managed chip forms in stable cuts, which improves process reliability and reduces chip interference during turning cycles.

How important is the holder choice for this insert? Holder compatibility is critical: the insert’s form, relief angle, tolerance class, fastening method, size and thickness determine fit and performance; matching the holder ensures correct seat and cutting geometry.

Is the corner radius suitable for finishing operations? The 0.8 mm corner radius offers a compromise between strength and finish quality, enabling precise surface textures while maintaining edge robustness in finishing cuts.
