TPMT 110304 AH8015 Wendeplatten - Tungaloy

Combine the PVD‑coated AH8015 grade with a compact 0.4 mm corner radius and 11° relief for a reliable balance of wear resistance and cutting‑edge stability in the machining of heat‑resistant alloys; order the insert directly via Metav Werkzeuge or consult the technical team for holder compatibility.

TPMT110304-TM AH8015 – ISO triangular turning insert, 0.4 mm radius, 11° relief (Tungaloy)

The TPMT110304-TM AH8015 is an ISO‑standard triangular turning insert designed for external and internal turning of heat‑resistant alloys with a focus on stable edge performance and broad machining versatility.

• PVD-coated carbide AH8015 for heat-resistant alloys
• 0.4 mm corner radius for consistent edge strength
• 11° relief angle for stable cutting geometry
• ISO triangular shape with central hole and countersink

High productivity through balanced wear resistance

The AH8015 grade is a PVD‑coated carbide formulated as a first choice for general machining of heat‑resistant alloys, offering a considered compromise between wear resistance and cutting‑edge stability. In practice, this balance reduces unplanned tool changes and supports longer tool runs, which contributes to improved machine utilisation and a more consistent surface finish. The applied coating increases thermal resistance at the cutting edge, which is particularly relevant when turning alloys that tend to work‑harden or generate elevated temperatures.

Stable cutting geometry for repeatable results

A combination of a 0.4 mm corner radius, 11° relief and a triangular 60° insert angle creates a robust cutting edge that copes well with variable feed and depth‑of‑cut conditions. The moderate corner radius enhances edge strength and helps avoid premature chipping during interrupted cuts, while the relief angle minimises rubbing and supports efficient chip formation. The insert’s 3.18 mm thickness and central hole with a cylindrical bore and single‑side countersink (40°–60°) ensure secure clamping in standard ISO holders, maintaining positional repeatability and dimensional stability in serial production.

Easy integration into ISO turning systems

As part of an ISO series, the plate integrates into standard turning tool systems where compatibility is defined by form, relief angle, tolerance class, fastening, size and thickness. The system build typically comprises the ISO insert, a matching external holder or boring bar, a seating pad or clamp set and replacement screws. Selecting the correct chipbreaker (TM) and insert grade for the workpiece material and machining strategy enables a predictable machining window and reliable surface quality, simplifying process planning and reducing setup iterations.

FAQ

Which materials are best suited for this insert?
The TPMT110304-TM AH8015 insert is primarily intended for heat‑resistant alloys; the AH8015 grade provides a balance of wear resistance and edge stability suited to such materials.

Is the insert compatible with standard ISO triangular holders?
Yes. The plate follows ISO dimensions and requires a holder matching the insert form, relief angle, tolerance class, fastening type, size and thickness.

What does the TM chipbreaker offer in practice?
The TM chipbreaker supports controlled chip formation in a range of turning conditions, improving surface finish and helping to avoid problematic long chips during both external and internal turning.

How does the 0.4 mm corner radius affect cutting performance?
A 0.4 mm radius strengthens the cutting edge against chipping and is advantageous for stable finishing passes or when occasional interruptions occur, while still allowing good surface integrity.

Which reference is useful when ordering replacements?
Use the manufacturer article number 6825797 or the SKU 6825797-Tungaloy when reordering to ensure the correct insert and grade are supplied.
