TPMT 16T308 GT9530 – ISO triangular turning insert for Turning, 0.8 mm radius (Tungaloy)

A TPMT16T308-PS GT9530 is an ISO triangular turning insert designed for finishing and light universal turning on steel, offering a balance of surface quality and tool life in stable setups.

• Wear-resistant GT9530 cermet grade
• 0.8 mm corner radius for superior surface finish
• 11° relief angle for stable cutting
• ISO triangular 16 mm format with centring hole

High productivity through stable cutting performance

The coated cermet grade GT9530 combines wear resistance with a cutting geometry tailored for finishing and light general-purpose turning on steel, yielding extended tool life and fewer changeovers. The modest 0.8 mm corner radius reduces cutting forces while maintaining an excellent surface finish, which helps to lower rework and downstream polishing effort. In stable clamping and machine conditions, the result is a measurable improvement in process efficiency and cost per component.

Designed for consistent mounting and machine compatibility

Compatibility with toolholders is determined by form, relief angle and precise dimensions; the insert features an 11° relief angle, a 16 mm triangle format and a central hole with a cylindrical bore plus a one-sided countersink (40°–60°). These specifications ensure repeatable seating and clamping in standard ISO holders. Clear adherence to ISO norms simplifies tool inventory and reduces setup time across multiple machines.

Efficient cutting behaviour and chip control

Equipped with the PS chipbreaker and a coated cermet substrate, the grade prioritises stable chip formation and a fine workpiece surface. Cermet materials provide a harder edge than conventional carbides for finishing tasks, enabling a reduction in feed-related vibration and improved dimensional stability. The coating and substrate combination supports longer cutting lengths under stable cutting conditions, translating into lower tool consumption during batch runs.

Practical application guidance for turning operations

Best suited for finishing and light universal turning on steel, the insert’s geometry and thin 3.97 mm plate thickness favour rigidity in supported setups. Matching insert grade and chipbreaker to workpiece material and clamping stability is essential: select this grade where surface quality and extended life outweigh aggressive metal removal. For unfamiliar materials or marginally stable setups, trial cuts at conservative feeds and speeds are advisable to validate performance.

FAQ

What materials is this insert suited for? This insert is specified for finishing and light universal turning on steel; the GT9530 coated cermet provides wear resistance and good surface finish for such applications.

How does the chipbreaker PS affect machining? The PS chipbreaker on the TPMT16T308-PS promotes controlled chip formation and evacuation, improving process stability and surface quality during finishing operations.

Which holders are compatible with this ISO insert? Compatibility depends on holder form, relief angle (11°), tolerance class, fixation method, size and thickness; the insert requires an ISO triangular holder designed for a 16 mm insert with a central locating hole.

Can the insert be used for heavy roughing? This grade and geometry are optimised for finishing to light universal turning; for heavy roughing, a more robust grade or different insert geometry should be selected.

What benefits does the GT9530 cermet offer compared with conventional carbide? GT9530 cermet offers a harder edge and improved surface finish in finishing applications, extending tool life under stable cutting conditions and lowering the need for rework.
