TPGT090204 UX30 Tungaloy turning insert — triangular 60°, 0.4 mm radius

The TPGT090204 UX30 is an ISO-standard triangular turning insert designed for external and internal turning, offering a sharp uncoated carbide grade that prioritises low cutting forces and reliable chip formation.

• ISO triangular insert 60° geometry
• Uncoated carbide grade UX30
• Corner radius 0.4 mm for fine finishing
• Central hole with countersink, single-sided chipbreaker

Predictable chip control and efficient cutting

This insert is engineered for processes where stable chip formation and low cutting forces matter. The UX30 grade is an uncoated carbide with a deliberately sharp cutting edge that reduces cutting resistance and improves feed response; as a result, operators benefit from more consistent cycle times and less tool-induced vibration. The presence of a single-sided chipbreaker focuses the chip flow for standard turning operations and helps to avoid long stringy chips in routine production. Explanation of technical terms: an uncoated carbide insert offers a sharp edge and good toughness for low-force cutting, while a chipbreaker shapes chips to reduce interference with the workpiece and tool.

Geometry tuned for accuracy and surface quality

The triangular shape with a 60° included angle and a corner radius 0.4 mm delivers a balance between strength and finishing capability. A small radius reduces edge contact and is especially suited to fine-profile turning or light finishing cuts, improving part geometry and surface quality with minimal secondary passes. The insert’s 11° relief angle aids in reducing rubbing on the flank, which, combined with the precise geometry, supports repeatable dimensional accuracy on turned contours. For users requiring a cleaner finish, the small corner radius and sharp grade produce measurable improvements in surface roughness without sacrificing edge life.

System compatibility for streamlined integration

Designed as an ISO-standard turning insert, compatibility with toolholders is ensured by matching the insert’s form, relief angle, tolerance class, fastening type, size and thickness. The central cylindrical hole with a one-sided countersink (40°–60°) enables secure clamping in indexable holders and boring bars; this reduces indexing errors and simplifies replacement during production. Typical system components include a matching external holder or boring bar, an underlay/clamp set and replacement screws. For mainline turning and internal profiling, selecting the correct chipbreaker and grade for the workpiece material and setup stability will maximise productivity and reproducibility.

FAQ

What applications is this insert suited for?
The insert is intended for external and internal turning; the TPGT090204 UX30 excels where low cutting forces and reliable chip control are required.

What material is the insert made from?
The product uses uncoated carbide (Hartmetall) in the UX30 grade, chosen for its sharp edge and predictable cutting behaviour.

How is the insert clamped and located in a holder?
Clamping uses the central cylindrical hole with a one-sided countersink (40°–60°); compatibility relies on matching form, relief angle, tolerance class, fastening, size and thickness.

What surface finish can be expected with the 0.4 mm radius?
The corner radius 0.4 mm is suited to fine finishing and profile accuracy, reducing the need for additional finishing passes in many turning operations.

Is the chip control suitable for automatic feeding and turning centres?
Yes; the single-sided chipbreaker provides controlled chip formation appropriate for standard automatic feeding and common turning centre setups.
