TPMT 130308 GT9530 triangular turning insert — coated cermet, PSS chipbreaker, 0.8 mm radius — Tungaloy

TPMT 130308 GT9530 is a triangular ISO turning insert for finishing to light universal turning of steel, designed to deliver improved surface finishes and longer tool life under stable cutting conditions.

• ISO triangular turning insert TPMT 130308 GT9530
• Coated cermet grade GT9530 for longer life
• PSS chipbreaker for reliable chip control
• 0.8 mm corner radius for fine finishes
• 11° clearance angle; with cylindrical hole & countersink

Consistent finishing performance for stable turning operations

The TPMT 130308 GT9530 is engineered as a finishing to light universal-turning solution with a coated cermet cutting material that prioritises surface quality and wear resistance. The grade is optimised for steel, where consistent cutting conditions and tool support produce the best returns. The combination of the cermet coating and the insert geometry reduces flank wear and helps maintain dimensional stability over longer tool life, which in turn raises process efficiency and lowers downtime.

Geometry that improves surface finish and chip control

A specifically chosen 0.8 mm corner radius and the PSS chipbreaker deliver two clear benefits: improved surface integrity and controlled chip formation. The moderate corner radius produces a fine machined profile without aggressive loading, while the PSS breaker channels chips predictably for safer evacuation. The 11° clearance angle reduces rubbing at the flank and further protects the cutting edge, enabling reproducible finishes in serial production and minimising rework.

ISO compatibility and system integration for reliable clamping

Designed to the ISO plate family, the insert’s form, relief angle, tolerance class, attachment method, size and thickness determine holder compatibility. The system build typically comprises an ISO insert, a matching external holder or boring bar, an underlay/clamp set and replacement fixing screws. The insert’s triangular shape and 13 mm size suit many standard toolholders, while the cylindrical hole with one-sided countersink (40°–60°) ensures secure clamping and accurate seating in the pocket — a prerequisite for repeatable turning results.

Coating and substrate combine for extended productivity

The GT9530 coated cermet substrate is a wear-resistant finishing to light universal grade that balances surface quality with durable edge life under steady conditions. Coated cermet offers lower built-up edge tendency and improved heat resistance compared with uncoated grades, making it suitable where a superior finish is required alongside reliable performance. Production engineers seeking to increase machining uptime without sacrificing finish will value this balance, and technical advisors can advise on optimal chipbreaker and holder choices for specific setups.

FAQ

What materials is this insert best suited for? The GT9530 coated cermet grade is optimised for steel machining; the TPMT 130308 GT9530 insert is designed for finishing to light universal turning where a high-quality surface and longer tool life are required.

Which chipbreaker is fitted and what benefit does it provide? The insert uses the PSS chipbreaker, which promotes predictable chip formation and safer evacuation, improving tool life and surface integrity during stable turning operations.

How is holder compatibility determined for this ISO insert? Compatibility depends on form, relief angle, tolerance class, attachment method, size and thickness; the TPMT130308-PSS follows ISO rules for triangular inserts and seats with a cylindrical hole plus countersink.

What pocket and clamping features are required for reliable seating? A matching holder with a compatible pocket and clamp set is required; the cylindrical hole with one-sided countersink (40°–60°) secures seating and accurate alignment for repeatable results.

Is this insert suitable for deep roughing cuts? This grade is a wear-resistant finishing to light universal sort; it is intended for finishing and light turning rather than heavy roughing where different grades and geometries are typically used.
