Take advantage of the combination of a coated cermet grade (GT9530) and a defined 0.8 mm nose radius to achieve consistent finishing and longer tool life in stable turning operations; order the insert directly via Metav Werkzeuge or consult the technical team for holder compatibility.

TPMT16T308-PSS GT9530 ISO turning insert for finishing and light universal turning, Tungaloy

A TPMT16T308-PSS GT9530 indexable turning insert designed for finishing to light universal turning on steel, combining a coated cermet grade with an optimised chipbreaker for improved surface quality and extended interval between indexings.

• Coated cermet grade GT9530 for wear resistance
• ISO triangular insert 16T308, 60° geometry
• 0.8 mm nose radius for superior surface finish
• Central hole with cylindrical seat and 40°–60° countersink

Consistent fine finishing with a wear-resistant cermet grade

The GT9530 coated cermet is formulated for finish to light general-purpose turning of steel where surface integrity and longevity are priorities. The combination of a hard cermet top layer and an engineered coating reduces flank wear under stable cutting conditions, so fewer indexings are required and part finishing is more consistent. The 0.8 mm nose radius produces a fine surface without sacrificing dimensional control; this radius, together with the insert’s edge preparation, helps to achieve repeatable part quality across batches while keeping tool-change downtime low.

Secure seating and precise geometry for reliable clamping

A triangular 60° insert form provides rigidity and flexible orientation in ISO holders, while the central cylindrical hole plus a one-sided countersink (40°–60°) ensures positive clamping and repeatable positioning. The nominal thickness of 3.97 mm and the ISO designation 16T308 support a standardised system build consisting of a matched external holder or boring bar, backing pad and clamping set. Compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness, so selecting the correct holder and clamp is decisive for process security and tool life.

Improved machining efficiency for steel with a PSS chipbreaker

The integrated PSS chipbreaker is optimised for finishing cuts and light turning, promoting stable chip formation for steels and reducing the risk of built-up edge. Under stable machine and workpiece conditions, the grade offers extended life while maintaining an excellent surface finish, which can lower downstream dressing or polishing effort. The economic advantage arises from reduced frequency of insert changes and from predictable performance in repetitive production, which supports planning and reduces unplanned stoppages.

Workshop-ready specifics for easy integration and replacement

This ISO-standard insert is supplied in the TPMT form and is intended for use as part of a complete turning system: ISO insert, matching external holder or boring bar, backing pad/clamp set and replacement screws. The substrate is a cemented carbide base with a coated cermet cutting layer, combining toughness and wear resistance for finishing tasks. The product is identified under manufacturer article number 6998365 and manufacturer SKU TUN6998365, which simplifies procurement and inventory. The triangular form, centre hole style and precise clearance angle allow straightforward replacement without special modifications to standard ISO clamping systems.

FAQ

What materials is this insert suited for?
The TPMT16T308-PSS GT9530 insert is specified for turning steel in finishing to light universal operations; the GT9530 coated cermet supports good surface finish and extended life under stable conditions.

Which holders are compatible with this insert?
Compatibility is defined by the insert form, clearance angle, tolerance class, fastening, size and thickness; use ISO triangular turning holders designed for 16T308 inserts with appropriate clamping and backing pad geometry.

How does the PSS chipbreaker influence machining?
The PSS chipbreaker promotes stable chip formation during finishing cuts, reducing built-up edge and supporting consistent surface quality when machining steel under stable setups.

What are the key geometric specifications to check before purchase?
Verify the 16 mm inscribed circle size, 3.97 mm thickness, 0.8 mm nose radius and 60° geometry to ensure correct fit and performance in the intended holder.

How is the insert identified for reordering?
Reorder using the manufacturer article number 6998365 or the SKU 6998365-Tungaloy; the manufacturer SKU TUN6998365 is also a reliable reference.
