TCMT 16T312 AH725 ISO turning insert — PVD-coated carbide, 60° triangle by Tungaloy

The TCMT16T312 AH725 is a triangular ISO turning insert designed for reliable external and internal turning where process security and stable chip formation are required.

• PVD-coated AH725 carbide grade
• Universal for steel and stainless steels
• ISO 60° triangular insert
• 1.2 mm corner radius for controlled finish

Consistent process security across mixed materials

The AH725 grade is a PVD-coated carbide developed for universal, breakage‑resistant performance on steel and stainless steel, delivering stable chip formation even when workpiece materials vary. Choosing this grade reduces the risk of unexpected insert failure and supports a steadier production rhythm. The coating improves wear resistance and helps maintain cutting-edge life under moderate to demanding conditions, translating into fewer tool changes and higher uptime.

Geometry engineered for repeatable clamping and surface quality

A 60° triangular format combined with a 1.2 mm corner radius provides a balance between strength and edge engagement: the included angle supports versatile cutting directions while the corner radius aids in achieving consistent surface finish without excessive cutting forces. The insert thickness of 3.97 mm and the cylindrical hole with single-side countersink (40°–60°) ensure secure seating and repeatable clamping in ISO‑compliant holders, reducing runout and improving dimensional stability on each changeover.

System-friendly selection and efficient handling for productive turning

As part of an ISO insert system, the TCMT16T312 fits into established toolholders, clamping assemblies and screws; compatibility depends on form, clearance angle, tolerance class, fixation, size and thickness. The one-sided chipbreaker provided supports controlled chip evacuation in many turning scenarios, while the AH725 grade offers a pragmatic balance between toughness and wear resistance. For stable, productive turning, combine the insert with a matching external holder and the correct clamp set; refer to the manufacturer SKU for ordering and inventory control.

FAQ

Which materials is this insert suitable for?
The TCMT16T312 AH725 insert is specified for machining steel and stainless steel; the AH725 PVD-coated carbide grade is optimised for universal use with emphasis on stable chip formation.

What does the 60° triangular shape mean for machining?
A 60° triangle offers versatile clamping positions and good access for external and internal turning; the geometry supports both roughing and finishing when paired with the appropriate corner radius and holder.

How is compatibility with holders ensured?
Compatibility depends on insert form, clearance angle, tolerance class, fixation, size and thickness; referencing the designation TCMT16T312 and Manufacturer SKU TUN6864990 will aid in selecting the correct ISO holder and clamping set.

What kind of chip control can be expected?
The one-sided chipbreaker together with the AH725 grade promotes controlled chip formation and evacuation, reducing the likelihood of entanglement or poor surface quality in many turning operations.

When should an alternative grade or chipbreaker be chosen?
Select an alternative when facing highly abrasive materials, very high cutting speeds or when processing hardened steels; adjust the chipbreaker and grade according to workpiece material, tool overhang and required process security.
