TPMT090208 AH725 – ISO indexable insert for turning, PVD-coated carbide, Tungaloy

TPMT090208 AH725 is an ISO-format triangular indexable insert designed for secure external and internal turning where process stability and predictable chip control are required

• ISO TPMT090208 fits standard holders
• AH725 PVD-coated carbide for steel and stainless
• 0.8 mm corner radius for stable cutting
• One-sided chipbreaker for controlled chips

Higher process security with PVD-coated carbide

The insert’s PVD-coated AH725 grade delivers a balance of wear resistance and fracture toughness, making it suitable for mixed batches and applications with varying material demands. The PVD coating improves edge life under intermittent cuts and raises thermal stability, which reduces unexpected tool changes and downtime. With its carbide substrate, the component provides predictable tool life in shop-floor conditions, so cycle times remain steady and regrinding intervals can be planned reliably.

Consistent chip control and geometry for dependable results

Engineered as an ISO-indexed triangular insert, the geometry and one-sided chipbreaker promote controlled chip formation during both external and internal turning. The defined 11° relief angle and 60° included angle support effective cutting engagement and reduce the tendency for built-up edge on stainless steels. This results in improved surface finish and fewer interruptions due to inconsistent chips, which is particularly beneficial for operators handling small tools or variable feed conditions.

Practical dimensions and mounting that speed up changeovers

With a plate thickness of 2.38 mm, a size 09 designation and a 0.8 mm corner radius, the insert provides a compact but robust cutting edge for fine turning and profile work. The insert is specified with a hole—a cylindrical hole with a single-sided countersink (40°–60°)—allowing straightforward clamping in compatible ISO holders and minimising setup time. Standardised dimensions mean replacements are immediately compatible with holders that accept TPMT090208 formats, simplifying inventory and reducing machine downtime.

Universal grade for mixed-material workflows

The AH725 grade is described for universal, break-resistant performance on steel and stainless steels, making this insert a useful choice where workpieces or batch materials change frequently. The combination of toughness and wear resistance reduces the risk of unexpected edge chipping on unstable setups while still preserving acceptable wear rates in continuous operations. For shops seeking a single, reliable indexable solution across a range of steels, this insert offers a productive compromise between life and edge security.

FAQ

What materials is the TPMT090208 AH725 best suited for?
The TPMT090208 AH725 insert is specified for steel and stainless steels; the AH725 PVD-coated carbide grade provides a compromise of wear resistance and toughness suited to mixed-material production.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius increases edge strength and improves surface finish in turning operations; it provides greater stability on short, rigid setups and reduces the risk of edge chipping on interrupted cuts.

Is the insert compatible with standard ISO holders?
Yes, the TPMT090208 follows ISO dimensions and the cylindrical hole with single-sided countersink is designed for secure clamping in compatible ISO-format holders.

What benefits does the AH725 PVD coating deliver?
The PVD coating on the AH725 grade enhances thermal resistance and reduces abrasive wear, extending edge life under higher cutting temperatures and intermittent cutting conditions.

Can this insert be used for both external and internal turning?
The geometry and chip control features of this triangular insert make it suitable for both external and internal turning tasks, provided the holder and setup match the ISO TPMT090208 format.
