TCMT 16T308 AH725 Turning indexable insert – Tungaloy

The TCMT16T308 AH725 is an ISO‑standard triangular turning insert designed for reliable external and internal turning in mixed‑material production environments.

• ISO‑standard triangular geometry
• PVD‑coated AH725 universal grade
• Suitable for steel and stainless steels
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance for mixed‑material production

The combination of a PVD‑coated surface and the AH725 universal grade carbide delivers consistent tool life across varied workpiece materials. The grade is formulated for fracture resistance, which reduces unexpected insert loss on interrupted cuts or unstable setups and thereby improves overall equipment effectiveness. Using a universal cutting grade minimises tool inventory while maintaining process security for continuous production.

Easy integration into existing ISO tooling systems

As an ISO‑standard indexable insert, compatibility with toolholders depends on geometry, 7° relief (frewinkel), tolerance class, fastening method, size and thickness. The 60° approach angle and standard TCMT form make the insert suitable for many commercially available external holders and boring bars. The modular system—insert, matching holder, shim/clamp set and replacement screws—ensures quick reassembly and short setup times, supporting higher uptime and consistent component quality.

Robust geometry and secure clamping for better part finish

The triangular plate shape with 0.8 mm corner radius and 3.97 mm thickness provides a balance between edge strength and surface finish capability. The central cylindrical hole with one‑sided countersink (40°–60°) ensures precise and repeatable clamping, reducing vibration and improving dimensional stability. The integrated one‑sided chipbreaker helps control chips in turning operations, enhancing surface integrity and evacuation when machining interrupted or variable feeds.

Practical recommendations for turning applications

Designed primarily for external and internal turning, the insert suits both conventional and semi‑finish cuts where process reliability is essential. Select the appropriate chipbreaker and match the grade to the workpiece and clamping stiffness: the AH725 grade is particularly effective when machining a mix of steel and stainless steels or when smaller tool sizes are required. For critical parts, pair the insert with a rigid holder and appropriate feed to exploit the grade’s fracture resistance and maintain consistent component quality.

FAQ

What materials is the TCMT16T308 AH725 suitable for?
The TCMT16T308 AH725 indexable insert is specified for machining steel and stainless steels; the AH725 PVD‑coated carbide provides stable chip formation and resistance to chipping on mixed‑material production.

How does the insert secure to the holder?
The insert uses a central cylindrical hole with a one‑sided countersink (40°–60°) for positive clamping; this ensures repeatable seating when combined with the correct shim and clamp set for the TCMT form.

Which operations are recommended for this insert?
The insert is intended for both external and internal turning, where a balance of edge strength and surface finish is required; it performs well in finish and semi‑finish passes under appropriate cutting conditions.

What does the 0.8 mm corner radius affect in practice?
A 0.8 mm corner radius increases edge strength and improves surface finish consistency; it helps absorb cutting shocks and is suitable for moderate‑feed finishing and semi‑roughing, depending on part tolerance and rigidity.

Is the AH725 grade suitable for unstable clamping setups?
Yes, the AH725 grade is engineered for fracture resistance and is especially useful when tool size is small or when setup rigidity is limited, as it reduces the risk of unexpected edge failures.
