TPMX 170408 AH8015 — Indexable insert for drilling (triangular, PVD-coated) by Tungaloy

The TPMX170408R‑G AH8015 is an indexable insert for drilling systems, designed for general machining of heat‑resistant alloys and requiring size and seat verification with the drill diameter.

• PVD-coated carbide grade AH8015
• Triangular 17 mm format
• 0.8 mm corner radius
• Optimised for heat-resistant alloys

Consistent cutting performance through balanced grade and geometry

The combination of a PVD‑coated surface with carbide substrate in grade AH8015 provides a well balanced pairing of wear resistance and cutting‑edge stability for demanding drilling tasks. The coating reduces chemical affinity and thermal load at the cutting zone, which helps to maintain edge integrity during interrupted cuts typical for indexable drilling. As a result, process windows are wider and tool life becomes more predictable, supporting steady production rates.

Secure seating and repeatable indexing reduce downtime

The triangular 17 mm format with a defined 60° geometry and a 4.76 mm plate thickness gives a stable contact area in purpose‑built drill bodies. The insert features a special hole and is intended for clamping in a compatible drill body, so matching the insert seat and drill diameter is essential for correct assembly. Proper seating and clamping support repeatable tool indexing and reduce vibration, which in turn improves surface consistency and lowers the risk of premature edge failure.

Practical application guidance for reliable results

Designed for use in indexable drilling systems, the insert performs well on internal and external cutting edges when used for drilling operations. The built‑in chipbreaker G helps to control chip formation when machining heat‑resistant alloys, reducing the likelihood of chip congestion in deep holes. For best results, check compatibility between the drill body and the insert geometry before installation and follow the tool manufacturer’s recommendations for feed and speed ranges.

Production advantages: efficiency, stability and predictable tool life

Adopting this insert in a matched drilling system brings tangible production benefits: lower process variability, extended effective life compared with uncoated grades, and easier planning of tool changes thanks to predictable wear behaviour. The insert’s specification—PVD coating, AH8015 composition and 0.8 mm corner radius—supports a cost‑effective balance between edge stability and consumable replacement intervals in series production.
