TPGN 090204 DX140 Tungaloy indexable insert for turning — PCD, 60° triangle

A TPGN090204-DIA DX140 indexable insert engineered for precision turning of small components and bar-fed lathes

• PCD grade DX140 for high cutting speeds
• Long tool life for productive turning
• Triangle 60° geometry for fine parts
• 0.4 mm radius for precise edge control

High-speed performance for non‑ferrous and abrasive materials

The insert uses polycrystalline diamond (PCD) in the DX140 grade, optimised for machining aluminium, non‑ferrous metals and abrasive non‑metallic materials. The PCD cutting layer enables high cutting speeds, which reduces cycle times on bar‑fed lathes and small turning centres while maintaining dimensional stability. For production environments where throughput and consistent surface quality matter, this grade provides a predictable balance of speed and longevity, helping to lower per‑part machining costs.

Made for small-part turning and long-turning automatics

Designed as part of the MiniForce‑Turn series, the insert suits fine and small‑component workpieces typical in watchmaking, medical parts and micro‑mechanical assemblies. The triangular plate form and compact dimensions support secure clamping in mini toolholders and allow effective chip evacuation in continuous bar‑feed operations. Integration into automated turning lines is straightforward thanks to the standard ISO designation 090204, ensuring compatibility with common pocket and clamping systems.

Precision geometry that boosts surface finish and repeatability

A controlled geometry is central to performance: the 60° included angle and 0.4 mm corner radius produce accurate corner transitions and consistent part profiles, while the 11° relief angle reduces rubbing and heat generation at the cutting edge. The plate thickness of 2.38 mm contributes to mechanical stability during interrupted cuts, and the DIA chipbreaker promotes predictable chip formation when turning thin or difficult chips. Together, these features enhance surface finish and repeatability, especially on small diameters.

Robust substrate and economical production benefits

The body is manufactured from cemented carbide, providing a rigid foundation for the PCD layer and resisting deformation during prolonged runs. The insert is supplied without hole, simplifying indexing and reducing inventory complexity for certain toolholders. Long tool life and reduced tool change frequency translate into less downtime and lower tooling expenditure over production cycles. Traceable identification is available via the manufacturer SKU and article numbers for procurement and stock control.

FAQ

What materials is this insert suitable for? This insert uses the DX140 PCD grade and is suitable for aluminium, other non‑ferrous metals and abrasive non‑metallic materials when high cutting speeds and long tool life are required.

Which machines and applications is it intended for? The geometry and dimensions suit precision turning on small lathes and long‑turning automatics; the MiniForce‑Turn system compatibility supports bar‑feed production of fine components.

How does DX140 PCD compare with conventional carbide in this application? DX140 PCD on a cemented carbide body offers significantly higher wear resistance on non‑ferrous and abrasive workpieces than uncoated carbide, resulting in longer tool life and fewer tool changes for the same application.

What are the key geometric specifications to consider when selecting holders? Important values are the ISO code 090204, 60° included angle, 0.4 mm corner radius and 2.38 mm thickness; holders and pockets must accept triangular inserts with these dimensions.

Is the insert supplied with a hole for screw clamping? This article is supplied without hole, which is suitable for clamp‑style pockets designed for holeless triangular inserts.
