TPMX 170408 AH8015 – Indexable drilling insert, PVD-coated carbide (Tungaloy)

The TPMX 170408 AH8015 is an indexable triangular insert for drilling systems, designed for general machining of heat‑resistant alloys and for use in changeable‑plate drilling tools.

• PVD-coated carbide grade AH8015
• Designed for heat‑resistant alloys
• Triangular insert, 60° geometry
• 0.8 mm corner radius, 11° clearance

Precision and extended tool life for demanding alloys

The PVD‑coating and carbide substrate of this insert deliver a balance between wear resistance and edge robustness that suits demanding materials. The selected grade AH8015 is engineered as a first choice for general machining of heat‑resistant alloys, providing reduced flank wear and more consistent tool life. In production this translates into fewer indexings per micro‑batch, more predictable regrinds and steadier cycle times.

Consistent hole quality from optimised geometry

A triangular insert with a 60° geometry and a 0.8 mm corner radius ensures reliable engagement and uniform chip formation at the cutting edge. The 11° relief angle supports stable cutting without rubbing, helping to produce rounder holes and improved surface finish. For internal and external cutting edges the geometry reduces vibration sensitivity and contributes directly to dimensional repeatability.

Fast integration into indexable drilling systems

The insert is intended for use in complete drilling systems comprising a drill body, the matching insert, a clamping screw and the appropriate key; note that seat geometry and drill diameter must be matched to ensure correct fit. The design supports straightforward replacement of worn plates, which shortens downtime and simplifies tool logistics on the shop floor. Compatibility checks with the drill holder are recommended before first use.

Productivity gains and practical application guidance

By combining the PVD-coated surface with a carbide substrate the insert improves process security and overall productivity: stable cutting performance reduces scrap rates and helps maintain cycle times. Typical application is drilling with changeable‑plate tools where the material and cutting conditions call for an insert that balances edge stability and wear resistance. For optimal results, align feed and speed with the component material and toolholder rigidity; the insert is particularly effective in continuous production runs on heat‑resistant alloys.

FAQ

Which materials is this insert best suited for?

The TPMX170408R-BG AH8015 insert is optimised for general machining of heat‑resistant alloys and delivers a balanced combination of wear resistance and edge stability for such materials.

How does the 0.8 mm corner radius influence hole finish and tool life?

A 0.8 mm corner radius stabilises the cutting edge, reduces local stresses and contributes to improved hole geometry and surface finish while extending the time between indexings.

Can this insert be used with existing indexable drilling systems?

Yes — the insert is designed for use in indexable drilling systems, but correct matching of the insert seat and drill diameter is essential to ensure secure clamping and correct cutting geometry.

What is the purpose of the BG chipbreaker?

The BG chipbreaker on this plate promotes controlled chip formation and evacuation under typical drilling conditions, supporting stable cutting and consistent machining performance.
