TPMT110308-PS AH8005 — ISO triangular turning insert, PVD-coated carbide

TPMT110308-PS AH8005 is an ISO‑standard triangular turning insert designed for demanding external and internal turning where wear resistance and process stability are required

• PVD-coated carbide AH8005 for high wear resistance
• Triangular ISO insert with 0.8 mm corner radius
• 11° clearance angle for stable cutting
• Centring hole with 40°–60° countersink

Stable cutting and reliable chip control for tough materials

The insert grade is PVD-coated AH8005, a wear‑resistant carbide designed for machining heat‑resistant alloys and other hard materials under stable cutting conditions. Combined with the PS chipbreaker, this geometry promotes controlled chip formation and evacuation, reducing the risk of built‑up edge and unexpected tool failure. The result is a predictable process that supports higher material removal rates and fewer interruptions for regrinding or tool change, which in turn improves overall machining efficiency.

Fast, repeatable clamping and ISO compatibility

Manufactured to ISO dimensions, the triangular insert features a centring provision: a cylindrical hole with a single‑side countersink (40°–60°) and a plate thickness of 3.18 mm, ensuring a positive fit in the corresponding holders. The 11° clearance and the triangular form simplify seating and orientation, shortening setup time and lowering the chance of misalignment. For production environments that change operations frequently, this predictability reduces setup variance and supports consistent part quality across shifts.

Better surface quality and longer in‑service intervals

With a 0.8 mm corner radius, this insert balances edge strength and surface finish: small radii increase edge robustness in interrupted cuts while still producing an acceptable finish on most turned components. The PVD coating enhances wear resistance, especially at elevated temperatures, which translates into longer intervals between insert changes and less operator intervention. As a result, machining becomes more economical through reduced tooling costs per part and a steadier production flow.

FAQ

What materials is this insert best suited for?
The TPMT110308-PS AH8005 is intended for machining heat‑resistant alloys and other hard materials; the AH8005 PVD‑coated carbide offers improved wear resistance under these conditions.

How does the PS chipbreaker affect performance?
The PS chipbreaker on this insert promotes controlled chip formation and evacuation during turning, which enhances process stability and reduces the likelihood of surface defects.

Can this insert be used in standard ISO holders?
Yes. The TPMT110308-PS AH8005 conforms to ISO dimensions; the centring hole and plate geometry ensure repeatable seating in matching ISO turning holders.

What cutting geometry helps achieve a good surface finish?
The 0.8 mm corner radius offers a compromise between edge strength and finish quality; combined with appropriate feeds and speeds, the radius supports improved surface finish while maintaining robustness.

Is the insert suitable for interrupted cuts or roughing operations?
The triangular geometry and 0.8 mm radius deliver sufficient edge strength for many interrupted and semi‑roughing operations, provided holder rigidity and cutting parameters are appropriate.
