TPGA 090202 DX140 Turning insert by Tungaloy — PCD, ISO triangular

The TPGA090202 DX140 is an ISO‑standard triangular indexable insert designed for external and internal turning of aluminium, non‑ferrous metals and abrasive non‑metallic materials.

• ISO triangular insert TPGA 090202
• PCD grade DX140 for aluminium & non‑ferrous
• 60° insert angle with 0.2 mm corner radius
• 2.38 mm thickness, cylindrical hole for clamping

Increase throughput with PCD performance

The combination of polished PCD cutting edges and the DX140 grade enables significantly higher cutting speeds when machining aluminium and other non‑ferrous materials. Polycrystalline diamond offers exceptional wear resistance and low adhesion, which translates into fewer tool changes and longer uninterrupted cycles. For applications where abrasive inclusions or abrasive non‑metals are present, the PCD edge keeps the cutting geometry intact for extended runtimes, helping to increase overall productivity while maintaining consistent surface quality.

Secure seating and ISO conformity for repeatable results

Built to the ISO TPGA standard, the insert’s geometry, 11° relief angle and tolerance class ensure compatibility with matching holders and bores. The cylindrical hole and standard clamping interface provide a stable seat that reduces vibration and improves surface finish stability. When combined with the correct holder, underlay and clamping screws, the system supports repeatable positioning and simple replacement, which lowers setup time and improves process reliability.

Precision geometry for fine finishes and form control

The triangular form with a 60° included angle and 0.2 mm corner radius produces a small nose radius suitable for fine profiling and finishing passes. The absence of an integrated chipbreaker means chip control must be matched to the workpiece and machining conditions; selecting the appropriate chip former and cutting parameters helps to avoid built‑up edge and to control chip flow. This geometry is particularly effective where profile accuracy and close tolerance surfaces are required.

Substrate and grade engineered for longevity

The insert combines a tungsten carbide substrate with a PCD cutting layer to balance toughness and edge hardness. That construction supports high productivity in light‑to‑medium interrupted cuts and continuous finishing operations on aluminium and abrasive non‑metals. The DX140 grade is tuned to deliver long tool life under elevated cutting speeds, which reduces tooling consumption and contributes to a lower cost per part in high‑volume turning operations.

FAQ

Which materials is this insert intended for?
The TPGA090202 DX140 insert from Tungaloy is intended for aluminium, other non‑ferrous metals and abrasive non‑metallic materials, utilising the PCD cutting edge for extended wear resistance.

Is the insert compatible with standard TPGA holders?
Yes. The insert conforms to the ISO TPGA designation and its compatibility depends on matching holder form, relief angle of 11°, tolerance class, size and thickness.

Can this insert be used for finishing operations?
With its 0.2 mm corner radius and sharp PCD edge, the TPGA090202 DX140 is suitable for fine finishing and profiling where high surface quality is required.

How is the insert clamped in the toolholder?
Clamping is achieved via the cylindrical centre hole together with the appropriate underlay/shim, clamp set and screws to ensure a secure, repeatable fit.

Does this insert include a chipbreaker?
This version is supplied without a chipbreaker; chip control should be managed by selecting a suitable chipformer and optimising cutting parameters for the workpiece and stability.
