TPMT 130308 GT9530 — ISO triangular turning insert by Tungaloy (for turning)

TPMT130308-PM GT9530 is an ISO-standard triangular indexable insert designed for finishing and light general-purpose turning on steel, offering a balance of surface quality and extended tool life under stable cutting conditions.

• ISO-standard triangular insert
• Coated cermet grade GT9530
• 0.8 mm corner radius for fine finishing
• 11° clearance angle; 3.18 mm thickness

Consistent finishing through a coated cermet substrate

The coated cermet composition of this grade ensures improved surface finish and extended tool life in finishing operations. Cermet combines ceramic hardness with metal toughness, which reduces built-up edge and produces a finer machined surface compared with conventional grades; this is particularly notable in stable turning setups where vibration is limited. The PM-style chipbreaker supports predictable chip formation, helping to maintain dimensional integrity during both external and internal turning tasks. The result is fewer interruptions for regrinding or replacement and a more economical machining cycle.

Reliable mounting and geometry for stable cutting performance

Designed to the ISO-standard, compatibility with holders depends on shape, clearance angle and tolerance class; the insert’s 11° clearance angle and 3.18 mm plate thickness contribute to mechanical stability in the clamping zone. The insert features a cylindrical hole with a one-sided countersink (40°–60°) for secure locating and clamping, which reduces micro-movements during cutting. These geometric choices minimise vibration and make the grade a dependable option when a secure, repeatable interface between insert and toolholder is required.

Practical machining advantages and recommended usage

With a 0.8 mm corner radius, the insert is optimised for fine finishing where edge strength and surface integrity matter. The GT9530, a coated cermet grade, is intended for finishing to light universal applications on steel, giving a compromise between wear resistance and edge sharpness. For best results, pair the insert with a holder that matches form, free angle and tolerance; select the chipbreaker and grade to suit material, cut type and machine rigidity. The predictable performance reduces scrap rates and contributes to higher first-pass yields in production environments.

Simple system setup and service considerations

The insert is part of a system consisting of the ISO indexable plate, an appropriate external holder or boring bar, an underlay/clamping kit and spare screws — all contributing to a rapid exchange workflow. Using the correct underlay and torque for the clamping screws preserves the insert’s seating and extends service life. For shops that prefer standardised tooling, the ISO conformity supports straightforward stock management and rapid replacement without bespoke adaptors, thereby lowering downtime and supporting continuous production.

FAQ

What materials is this insert suited for?
The TPMT130308-PM GT9530 is a coated cermet insert optimised for machining steel in finishing to light universal operations.

How does the PM chipbreaker influence machining?
The PM chipbreaker on the GT9530 grade promotes controlled chip formation and improved surface quality during turning operations with stable setups.

Which holders are compatible with this ISO insert?
Compatibility is determined by holder form, clearance angle, tolerance class, clamping method, size and thickness; use an ISO-compatible external holder or boring bar sized for a 13 mm inscribed circle.

What benefits does the 0.8 mm corner radius offer?
A 0.8 mm corner radius balances edge strength and finishing capability, producing finer surfaces while maintaining adequate wear resistance for light turning tasks.

Is the insert supplied with mounting hardware?
The system requires a suitable underlay/clamping set and replacement screws; these are part of the tool system rather than the individual insert supply.
