TPMX 280716 AH8015 — Indexable insert for drilling systems by Tungaloy

A TPMX280716R-G AH8015 indexable insert engineered for drilling applications, optimised for heat‑resistant alloys and general metalcutting tasks

• PVD-coated carbide for improved wear resistance
• 1.6 mm corner radius for enhanced edge strength
• Triangular form with 60° geometry for stable positioning
• Chipbreaker G for reliable chip control

Longer tool life through high-performance coating

The PVD-coated carbide grade AH8015 combines a hard, wear‑resistant surface with an underlying substrate engineered for toughness. The protective coating reduces adhesive wear and oxidation at elevated temperatures, which translates into extended tool life and fewer index changes during production. For operations where consistent cycle times are crucial, this balance of wear resistance and edge stability helps to maintain process reliability and reduces unplanned downtime.

Geometry tuned for precise, repeatable holes

Designed as a triangular indexable insert with a 1.6 mm corner radius and 60° geometry, the plate supports stable cutting conditions and improved hole quality. The defined corner radius increases the load‑bearing area at the cutting edge, reducing chipping under intermittent entry conditions. Combined with the chipbreaker G, the geometry promotes predictable chip formation and evacuation, yielding a consistent surface finish and more reliable size control on internal bores with minimal secondary rework.

System-friendly design and practical handling

The insert is part of a model series for drilling bodies and must be matched to the drill diameter and seat geometry for correct use. The assembly typically comprises a drill body, the appropriate insert, a clamping screw and the corresponding key; the insert’s 7.94 mm plate thickness and triangular form ensure secure clamping and straightforward indexing. For workshop planning, the insert’s special centre hole style allows compatibility with specific drilling systems and provides mechanical stability during machining. This practical configuration supports efficient tool management and predictable replacement intervals.

FAQ

Which materials is this insert suitable for?
The TPMX280716R-G AH8015 insert is aimed at machining heat‑resistant alloys and a wide range of metals thanks to the AH8015 PVD‑coated carbide formulation.

How does the 1.6 mm corner radius affect performance?
A 1.6 mm corner radius increases edge strength and load distribution, reducing the risk of chipping and improving repeatability in drilling operations.

What does the chipbreaker designation G mean?
The chipbreaker G is configured to promote controlled chip formation during drilling, which assists chip evacuation and supports stable surface quality on bores.

Is this insert compatible with standard drilling bodies?
The plate is designed for use in indexable drilling systems; the seat and drill diameter must be matched to the insert’s geometry and special centre hole specification.
