TPGA110302 DX140 ISO triangular turning insert — PCD grade by Tungaloy

The TPGA110302 DX140 is an ISO triangular turning insert with a polycrystalline diamond cutting surface, optimised for high-speed turning of aluminium and non‑ferrous materials.

• PCD grade DX140 for extended tool life
• Triangular ISO form, 60° included angle
• 0.2 mm nose radius for fine detail
• Cylindrical-holed insert, 3.18 mm thick

Maximised productivity through PCD technology

The DX140 grade uses a polycrystalline diamond (PCD) cutting surface that is inherently hard-wearing and chemically stable against non-ferrous alloys. When machining aluminium and similar materials, the PCD edge enables significantly higher cutting speeds and a much longer tool life, which reduces downtime for insert changes and increases part throughput. The material behaviour of PCD minimises built-up edge on soft metals, which translates into more consistent surface finish and fewer scrap parts. This results-oriented design supports efficient production planning and clear cost-per-part improvements.

Geometry and clamping for repeatable accuracy

The insert’s triangular ISO form with a 60° included angle and a 0.2 mm nose radius provides a balance between cutting stability and detail capability. The 11° clearance angle ensures adequate relief to avoid rubbing while maintaining a strong cutting edge. Compatibility with standard ISO holders is governed by the insert’s form, clearance angle, tolerance class, fastening method, size and thickness, so reliable clamping and repeatable positioning are achieved when the correct holder and pad are selected. Predictable tool behaviour from the geometry reduces setup variability and supports tight process control.

Robust substrate and application range for economical machining

Brazed or bonded onto a cemented carbide substrate, the PCD layer on this insert is designed to combine the hardness of diamond with a shock‑resistant core. Grade DX140 is intended for aluminium, non-ferrous metals and abrasive non-metallic materials where long tool life and high cutting rates are required. The insert is supplied without a chipbreaker, so the selection of a chipformer and the appropriate grade should match workpiece material, machining type and machine stability. Reduced tool consumption and fewer tool changes mean lower process costs over production runs.

System considerations and practical use recommendations

An ISO insert functions as part of a system: the insert, a suitable external holder or boring bar, a support pad/clamping set and the correct fastening screws must be matched for secure operation. The TPGA110302 DX140 is supplied with a cylindrical hole for positive clamping and is 3.18 mm thick, which contributes to the overall stiffness of the cutting arrangement. For best results, select a holder that provides rigid support and favourable rake/clearance conditions; when machining thin-walled or unstable components, reduce feed or engage a different grade designed for lower vibration. If application conditions are uncertain, consultation on holder choice and process parameters is recommended to ensure consistent, economical machining.

FAQ

What materials is this insert best suited for? The TPGA110302 DX140 uses a PCD cutting surface and is optimised for aluminium, other non‑ferrous metals and abrasive non‑metallic materials where high cutting speeds and long tool life are required.

Can the insert be used for internal and external turning? Yes; the insert is designed for both external and internal turning when paired with the appropriate external holder or boring bar, clamping pad and fastening hardware.

How does the lack of a chipbreaker affect performance? The TPGA110302 DX140 is supplied without a chipbreaker, so chip control depends on the selected chipformer and machining parameters; this allows flexibility to match chip management to the workpiece and operation.

What does the cylindrical hole mean for clamping? The cylindrical hole ensures secure, repeatable clamping when used with compatible holders and clamping sets; correct matching of the hole style to the clamping hardware is essential for process stability.

Is the DX140 grade suitable for high-speed production runs? Yes, the DX140 grade is formulated for high cutting speeds and extended tool life in appropriate materials, offering economic advantages over frequent insert replacement.
