DNGA150404 DX140 – Indexable turning insert for high‑speed aluminium turning (Tungaloy)

DNGA150404 DX140 is an ISO-format indexable turning insert designed for high‑speed operations in aluminium and non‑ferrous materials, offering robust PCD performance in a rhombic, 55° geometry.

• ISO rhombic insert, 55° geometry
• PCD grade DX140 for aluminium
• 0.4 mm corner radius for fine turning
• Cylindrical hole for secure fastening

High-speed productivity with extended tool life

The DNGA150404 DX140 insert uses a polycrystalline diamond (PCD) cutting material specially formulated for aluminium and abrasive non‑metals, delivering markedly longer tool life compared with conventional grades. The DX140 grade enables significantly higher cutting speeds without compromising edge stability, which reduces cycle times and increases throughput. For production environments where uninterrupted machining and repeatable part quality are required, this insert offers a clear productivity advantage through reduced tool changes and consistent surface finish.

Reliable fitment and repeatable performance in ISO systems

Compatibility with standard toolholders is governed by the insert form, relief angle, tolerance class, fastening and thickness; the ISO designation ensures predictable interchangeability. The rhombic plate form with a 55° included angle and a cylindrical locating hole provides accurate seating and straightforward clamping in matching external holders or boring bars. Where process stability is critical, the consistent geometry and tolerance adherence of the ISO system simplify tool set‑up and contribute to reproducible results across batches.

Material suitability and process stability

The cutting material, PCD (polycrystalline diamond), is engineered for non‑ferrous workpieces such as aluminium and brass as well as abrasive composites. With a 0.4 mm corner radius, the insert is well suited to finishing cuts that demand a fine edge and superior surface quality. The underlying substrate is a cemented carbide body that supports the diamond layer and provides mechanical strength; this construction balances edge sharpness with robustness. Because the grade does not include a dedicated chipbreaker, machining strategy and clamping rigidity should be matched to feed and depth of cut to ensure effective chip control.

Practical handling and application guidance

The insert’s 4.76 mm plate thickness and 15 mm size offer a compact footprint that suits both external and internal turning operations when combined with the correct holder geometry. The cylindrical hole supports secure fastening and repeatable orientation, simplifying insert changes. For new applications, start with conservative feeds and progressively increase cutting speed within the DX140 capability while monitoring edge condition; this approach helps to exploit the insert’s high‑speed potential without risking premature wear. Technical advice and cutting‑parameter recommendations are available to ensure optimal integration into existing processes.

FAQ

What materials is this insert intended for?
The DNGA150404 DX140 insert is intended primarily for aluminium and other non‑ferrous materials, and it also performs well on abrasive non‑metallic workpieces thanks to its PCD cutting material.

Is the insert compatible with standard ISO holders?
Yes, the DNGA150404 follows ISO dimensions and will fit holders designed for 150404 inserts; compatibility depends on matching form, relief angle, tolerance class, fastening and thickness.

Why choose the DX140 grade for aluminium work?
The DX140 PCD grade offers superior edge retention and allows higher cutting speeds on aluminium, which translates into longer tool life and improved surface finish for the DNGA150404 insert.

How should chip control be managed given there is no chipbreaker?
Without an integrated chipbreaker, the machining strategy for the DNGA150404 should focus on appropriate feed, depth of cut and secure clamping to ensure controlled chip flow and process stability.

What indicates the end of tool life for this insert?
Wear signs such as edge rounding, increased cutting forces, loss of surface quality or unusual vibration suggest the DNGA150404 insert requires replacement to maintain part quality and tool life.

Can the insert be used for internal turning?
Yes, the DNGA150404 can be used for both external and internal turning when installed in the correct boring bar or holder that accommodates ISO 150404 inserts.
