TPMT 110208 AH725 turning insert (triangular, PVD-coated carbide) — Tungaloy

The TPMT 110208 AH725 is an ISO-standard triangular insert for external and internal turning, optimised for Stahl and rostfreier Stahl and designed to offer reliable performance in mixed-material production.

• ISO triangular insert, size 11
• PVD-coated carbide grade AH725
• 11° clearance angle for stable cutting
• Cylindrical hole with 40°–60° countersink

Predictable set-up through ISO conformity and clear compatibility

The insert is built to an ISO-standard form so that compatibility with external holders and boring bars is predictable; compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness. Using an ISO-matched system reduces set-up time and ensures repeatable positioning when replacing indexable tools. The described system typically comprises the insert, a matching external holder or boring bar, a shim or clamping set and replacement screws, which together deliver secure seating and repeatable geometry for series production.

Durable grade and coating for varied workpieces

The AH725 grade is a PVD-coated carbide developed as a universal, breakout-resistant solution suitable for Stahl and rostfreier Stahl. This combination provides enhanced wear resistance and good surface finish in interrupted or mixed-material operations, while remaining economical for smaller tools and applications with high demands on process security. The coating reduces flank and crater wear, enabling longer tool life and more consistent component quality under varying cutting conditions.

Geometry and chip control that support consistent productivity

The triangular design and 60° included angle offer a compact insert footprint for flexible tool positioning, while the 0.8 mm radius contributes to robust cutting edge strength for many finishing and light roughing tasks. The single-sided chipbreaker is engineered to control chip formation on the relevant cutting edge, improving evacuation and protecting the cutting edge. A 11° clearance angle and 2.38 mm thickness ensure stable cutting behaviour; the insert’s cylindrical hole with one-sided countersink (40°–60°) secures firm clamping and repeatable seating in the toolholder.

FAQ

What materials is this insert suitable for?
The TPMT 110208 AH725 insert from Tungaloy is suitable for Stahl and rostfreier Stahl; its AH725 PVD-coated carbide composition provides balanced wear resistance across these materials.

Which toolholders are compatible with this insert?
Compatibility depends on form, size, thickness, tolerance class, fastening and free clearance; the ISO-standard TPMT 110208 designation ensures widespread compatibility with holders and boring bars designed for ISO triangular inserts.

How does the corner radius affect machining results?
The 0.8 mm radius increases edge strength and contributes to smoother finishes at light to moderate depths of cut, while supporting stable performance during interrupted cuts with the AH725 grade.

What is the benefit of the single-sided chipbreaker?
A single-sided chipbreaker directs chip flow and improves evacuation on the active cutting edge, reducing the risk of built-up edge and promoting consistent surface quality when using the TPMT 110208 AH725.

Is the insert suitable for smaller tool bodies and demanding process security?
Yes, the AH725 grade is described as universal and breakout-resistant, making the insert well suited to smaller tools and applications where high process security is required.
