TPGW 080202 DX140 – Turning indexable insert by Tungaloy (PCD, ISO 080202, for turning)

The TPGW080202-DIA DX140 is a triangular ISO indexable insert designed for high-speed external and internal turning of aluminium, non‑ferrous metals and abrasive non‑metallic materials, offering a robust chipbreaker and a carbide substrate for stable machining.

• PCD grade DX140 for aluminium and non-ferrous
• ISO 080202 triangular insert, 60° included angle
• Very long tool life at high cutting speeds
• Cylindrical hole with single-side countersink

Increase throughput with sustained high-speed turning

The use of polycrystalline diamond (PCD) in the DX140 grade enables substantially higher cutting speeds on soft and abrasive non‑ferrous materials compared with conventional carbide inserts. This material pairing reduces tool wear and the frequency of changeovers, delivering measurable productivity gains and a lower cost per part in continuous production. The long tool life of the PCD tip supports longer uninterrupted cycles and fewer process interruptions, which is a direct advantage for throughput-led operations.

Consistent surface quality through controlled chip formation

A precisely engineered DIA chipbreaker ensures predictable chip control and consistent surface finish on profiles and cylinders. The PCD cutting edge keeps its geometry for extended periods, which preserves dimensional accuracy over long runs. Where repeatability and surface integrity matter, the DX140 grade maintains form accuracy while reducing secondary operations, such as polishing or reworking, thereby streamlining downstream processes.

Secure clamping and geometry for repeatable results

The triangular shape with a 60° included angle, a 0.2 mm nose radius and an 11° relief angle provides a balance between edge strength and fine cutting capability. The insert’s cylindrical hole with single‑side countersink (40°–60°) improves seat stability and torque transmission when mounted in a matching holder, reducing micro‑movement and vibration. Compatibility with holders depends on form, relief angle, tolerance class, fastening, size and thickness, so correct system selection guarantees reproducible results.

Simple integration into ISO tool systems and easy maintenance

As part of an ISO‑standard insert system, the plate integrates with a wide range of external holders, shims and clamping sets. Replacement screws and underlays are standard components, allowing quick swaps on the shop floor and minimising downtime. The carbide substrate provides a firm base for the PCD layer, giving a robust combination that is suitable for both demanding single‑piece and batch production environments. The manufacturer’s system advice helps to match chipbreaker and grade to workpiece material and machine stability.

FAQ

What materials is this insert best suited for?
The DX140 PCD grade is optimised for aluminium, other non‑ferrous metals and abrasive non‑metallic materials; the TPGW080202‑DIA insert retains edge life under these conditions.

How is the insert secured in the holder?
The insert uses a cylindrical hole with a single‑side countersink (40°–60°) for positive seating; correct clamping parts and a matching holder form ensure stable fixation and repeatable positioning.

What is the purpose of the DIA chipbreaker?
The DIA chipbreaker promotes controlled chip formation and evacuation, improving surface finish and reducing the risk of chip entanglement during high‑speed turning.

Can the insert be used for internal as well as external turning?
Yes, the ISO triangular design and PCD cutting edge make it suitable for both external and internal turning where geometry and holder access permit.

Which product reference should be quoted when ordering?
Please quote the designation TPGW080202‑DIA DX140 or SKU 6821537‑Tungaloy to ensure the correct grade and geometry are supplied.
