TCMT16T308 AH725 indexable turning insert (ISO 16T308) by Tungaloy — PVD-coated carbide, 0.8 mm radius, for turning

TCMT16T308 AH725 is an ISO-standard triangular indexable insert engineered for reliable external and internal turning across a wide range of steels and rostfreier Stahl.

• PVD-coated carbide AH725 for steel and rostfreier Stahl
• Triangle 16 mm plate with 0.8 mm corner radius
• 7° clearance angle for stable cutting
• Cylindrical hole with countersink for secure clamping

Consistent performance through advanced grade and coating

The AH725 grade is a PVD-coated carbide designed for universal, chip-resistant performance when machining steel and rostfreier Stahl. Because the coating improves edge stability and wear resistance, the insert maintains cutting geometry longer under mixed-material conditions, which translates into fewer interruptions for tool changes and a more predictable production flow. The single-sided chipbreaker supports consistent chip formation in typical turning tasks, reducing the risk of built-up edge and improving surface finish. These technical characteristics create a tangible efficiency advantage on batch runs and mixed-series production.

Precise geometry and ISO compatibility for repeatable set-ups

The insert is an ISO-design triangular plate with a nominal size of 16 mm and a 0.8 mm corner radius, a 7° clearance angle and a plate thickness of 3.97 mm. The cylindrical hole with one-sided countersink (40°–60°) affords secure clamping and repeatable seating in ISO holders. Compatibility with a given toolholder is determined by form, freiwinkel, tolerance class, clamping method, size and thickness; these parameters ensure a correct fit and stable cutting conditions. When fitted in a suitable external holder or boring bar, the geometry supports stable cutting forces and predictable tool life, contributing to consistent part quality and reduced set-up variance.

Application guidance and selection for reliable machining

Intended primarily for turning, the insert is suitable for both external and internal operations where a universal, robust grade is required. Select the chipbreaker and cutting grade according to workpiece material, machining strategy and machine-tool stability; the AH725 grade is particularly useful for smaller tools and operations demanding high process security. For precise tool selection, compatibility checks and optimisation of cutting data, technical data sheets and machining trials are recommended.

FAQ

What materials is the insert suitable for?
The TCMT16T308 AH725 insert is engineered for machining various steels and rostfreier Stahl, offering good chip control and reliable edge stability in common turning applications.

What are the key geometric features and how do they affect use?
The insert features a 0.8 mm corner radius, 60° included angle and a 7° clearance angle; this combination supports a balance between strength and finish, favouring stable cutting and repeatable part geometry.

How is the insert clamped and which holders are compatible?
Clamping uses a cylindrical hole with a one-sided countersink (40°–60°); compatibility with a holder follows ISO standards and is determined by form, freiwinkel, tolerance class, clamping method, size and thickness.

Is the insert coated and what benefits does the coating provide?
Yes — the AH725 grade is a PVD-coated carbide; the coating improves wear resistance and edge stability, helping to extend tool life and maintain surface quality under mixed or demanding conditions.
