SNGA 120404 DX140 Tungaloy indexable turning insert (PCD) for turning

The SNGA 120404 DX140 is an ISO indexable turning insert designed for external and internal turning of aluminium, non‑ferrous metals and abrasive non‑metallic materials.

• ISO indexable insert SNGA 120404 DX140
• PCD cutting material for aluminium and non‑ferrous
• Square shape, 12 mm size, 90° cutting angle
• 0.4 mm corner radius for precise profiling
• Cylindrical hole, 4.76 mm thickness for secure clamping

Boost throughput with PCD technology and high cutting speeds

The use of polykristalliner Diamant (PCD) in the cutting material provides a decisive productivity advantage when machining non‑ferrous alloys. Thanks to the DX140 grade, the insert enables high cutting speeds and delivers a very long tool life, especially on abrasive aluminium alloys and other non‑ferrous materials. This directly reduces tool changes and downtime, improving process economy in serial and continuous production. For applications requiring rapid material removal at stable surface quality, the PCD grade offers predictable performance and repeatable results.

Stable clamping and geometry for reliable turning

The square form and 90° cutting angle create a robust seating and allow multiple indexed edges per insert, increasing usable edge life. The cylindrical hole and 4.76 mm plate thickness ensure secure clamping in compatible ISO holders; compatibility depends on form, clearance angle, tolerance class, fastening, size and thickness. The moderate 0.4 mm corner radius supports precise profiling and maintains edge strength for light to medium cuts, supporting consistent dimensional accuracy across workpieces.

Applications, material range and process benefits

Designed for turning, the insert is optimised for aluminium, non‑ferrous metals and abrasive non‑metallics, where PCD excels. The carbide substrate provides stable support for the diamond cutting layer, combining toughness with wear resistance. With no integrated chipbreaker (without chipbreaker), process planning should consider feed and depth settings to manage chip formation; where required, select an appropriate holder or downstream chip control. The result is lower total tooling cost per part, improved surface finish and fewer interruptions for insert changes.

FAQ

Which materials are suitable for this insert?
The SNGA 120404 DX140 Tungaloy indexable turning insert is specified for aluminium, non‑ferrous metals and abrasive non‑metallic materials, where the PCD cutting material provides high wear resistance and extended life.

Is this insert suitable for roughing or finishing operations?
With a 0.4 mm corner radius and no integrated chipbreaker, the insert is particularly well suited to finishing and light to medium cutting tasks; for heavy roughing, pairing the insert with an appropriate holder and cutting parameters is recommended.

How is compatibility with tool holders ensured?
Compatibility is determined by the insert form, clearance angle, tolerance class, fastening method, size and thickness; the SNGA 120404 DX140 must be matched to an ISO‑compatible holder that accepts square inserts with a cylindrical hole.

What advantages does the DX140 PCD grade offer?
The DX140 grade delivers high cutting speeds and very long tool life in aluminium and non‑ferrous machining, reducing tool changes and improving process efficiency for high‑volume production.

What are the manufacturer and item references for ordering?
Manufacturer article number: 6806458; Stock SKU: 6806458‑Tungaloy; Manufacturer SKU: TUN6806458 — refer to these identifiers when specifying the Tungaloy indexable insert.
