TPGA160308 DX140 turning insert by Tungaloy — ISO triangular insert for non‑ferrous machining

The TPGA160308 DX140 is an ISO‑format turning insert designed for external and internal turning of aluminium, non‑ferrous metals and abrasive non‑metals, providing high‑speed performance and extended life.

• PCD grade DX140 for abrasive materials
• ISO‑standard triangular insert 16 mm
• Suitable for high cutting speeds
• Cylindrical hole for secure clamping

Optimised high‑speed performance for non‑ferrous turning

The insert is engineered around a polycrystalline diamond (PCD) cutting layer, graded DX140, which is specified for high abrasiveness and aggressive feed rates. This combination results in very long tool life and reduced tool change frequency, improving uptime in serial production. The cutting concept is particularly efficient for aluminium and non‑ferrous alloys, where the hard PCD surface maintains a sharp edge at elevated speeds and resists abrasive wear from non‑metallic inclusions.

Precise geometry and measurable advantages in set ups

Compatibility with ISO holders is defined by form, clearance angle, tolerance class, attachment method, size and thickness, and this insert follows ISO conventions to simplify tool‑planning. Key geometry data such as a 16 mm inscribed circle, 0.8 mm corner radius and 3.18 mm thickness enable predictable cutting forces and surface finish. Using standardised inserts reduces set‑up time and ensures interchangeability across machines and carriers, making process planning more reliable.

Secure clamping and stable machining behaviour

The insert comes with a cylindrical hole, allowing controlled clamping and repeatable positioning relative to the toolholder. A triangular plate form with a 60° included angle and 11° clearance provides a stable cutting edge engagement and predictable chip formation when matched to an appropriate holder and feed strategy. Where surface quality and dimensional control matter, the stable geometry helps maintain concentricity and reduces vibration-induced deviation.

Application focus and practical benefits on the shop floor

Designed for turning, this insert performs best in applications requiring efficient removal of aluminium, brass and abrasive non‑metallic compounds. The absence of a chipbreaker means chip control relies on correct feed rates and holder geometry; this allows process engineers to tailor chip formation to machine capacity and workpiece geometry. The result is improved productivity through fewer interruptions and consistent component quality across batches.

FAQ

What materials is this insert suitable for?
The TPGA160308 DX140 insert is designed for aluminium, other non‑ferrous metals and abrasive non‑metallic materials, utilising its PCD cutting layer for high wear resistance.

Does the insert require a specific holder type?
Compatibility is defined by ISO form, clearance angle, tolerance class, attachment method, size and thickness; the insert is intended for holders matching the ISO TPGA form.

Can the insert be used at high cutting speeds?
Yes, the DX140 PCD grade is formulated for elevated cutting speeds typical in non‑ferrous turning, delivering extended life under suitably optimised conditions.

How does the cylindrical hole affect clamping?
The cylindrical hole allows secure, repeatable clamping and precise positioning in compatible toolholders, contributing to consistent machining performance.

Is a chipbreaker integrated into the insert design?
This variant is supplied without a chipbreaker, so chip control is achieved via appropriate feed, depth of cut and holder geometry.
