TPMT090208 AH725 — ISO turning insert for external and internal turning, Tungaloy

A TPMT090208 AH725 insert engineered for ISO-standard turning operations, offering robust edge security and universal performance in steel and stainless steel applications.

• ISO triangular insert TPMT090208, 11° relief
• PVD-coated carbide AH725 for steel & stainless
• 0.8 mm corner radius, reliable edge strength
• Cylindrical hole with one-sided countersink

Consistent chip control from geometry and chipbreaker

The triangular plate design with a single-sided chipbreaker provides stable chip formation and repeatable cutting behaviour, reducing vibration and improving surface finish. The fixed 11° clearance and the insert’s geometry promote predictable cutting forces; this leads to fewer rejects and smoother production cycles. Opting for a geometry-matched indexable plate enhances tool life by ensuring that the cutting edge meets holder specifications, which is especially valuable in small tools and high-precision turning.

Coating and substrate tailored for mixed-steel workloads

The combination of a PVD-coated surface and a carbide substrate in the AH725 grade gives a balance of toughness and wear resistance suited to both steel and stainless steel. PVD deposition forms a thin, adherent layer that reduces built-up edge and improves thermal resistance at the cutting edge. In practice, this means longer intervals between indexings and steadier dimensional control when machining variable materials, where a universal, break-resistant grade reduces the need for frequent insert changes.

ISO compatibility and secure mounting for reliable indexing

Manufactured to ISO plate dimensions, the insert’s fit depends on form, clearance angle, tolerance class, fastening method, size and thickness; the cylindrical hole with a one-sided countersink (40°–60°) ensures secure clamping in compatible holders. Verifying holder compatibility by checking these parameters prevents misalignment and premature wear. For both external and internal turning, the standardised specification simplifies stocking and replacement procedures and supports modular tool system planning.

Small dimensions, big impact on uptime

The modest 2.38 mm plate thickness and 0.8 mm corner radius combine to give a strong edge while permitting fine finish capability on smaller tools. The universal nature of the grade and the single-sided chipbreaker help reduce inventory complexity: fewer grades and geometries cover a wider range of tasks. When process security is the priority, these small technical choices reduce downtime, minimise set-up adjustments and support consistent output quality.

FAQ

What materials is this insert suitable for?
The TPMT090208 AH725 insert from Tungaloy is formulated for machining steel and stainless steel, offering a universal balance of toughness and wear resistance.

How is the insert secured in the holder?
Mounting uses the cylindrical centre hole with a one-sided countersink (40°–60°), ensuring correct indexing and a secure clamp in holders designed for ISO triangular plates.

What benefits does the AH725 grade provide?
The AH725 PVD-coated carbide grade provides a break-resistant edge and reliable process security across varying steels, reducing the frequency of insert changes in mixed-material production.

Can the insert be used for both external and internal turning?
Yes, the ISO-standard triangular format and the specified geometry make it suitable for both external and internal turning applications when paired with an appropriate holder.

What is the effect of the 0.8 mm corner radius?
A 0.8 mm corner radius increases edge strength and helps absorb intermittent cutting forces, improving tool life while still enabling good surface finish on many turning tasks.
