TPGW16T308 DX140 Tungaloy turning insert (PCD, 60° triangle)

TPGW16T308 DX140 indexable turning insert for high-speed machining of aluminium and other non-ferrous and abrasive non-metallic materials

• PCD for high-speed machining
• ISO 16T308 triangular form
• Long tool life on aluminium
• 60° geometry with 0.8 mm radius

Maximise productivity with a PCD grade designed for aluminium

The DX140 grade, based on polykristalliner Diamant (PCD), is engineered to deliver high-speed performance and exceptional wear resistance when machining aluminium and other non-ferrous materials. The diamond cutting layer maintains a sharp edge far longer than conventional carbide, which translates into fewer index changes and more uptime on the shop floor. This leads to measurable efficiency gains in batch production and lowers the overall tooling cost per component when abrasive inclusions or non-metallic laminates would otherwise accelerate wear.

Consistent part quality thanks to precise geometry and secure clamping

A 60° triangular format with a 0.8 mm corner radius and an 11° clearance angle produces repeatable cutting engagement and stable chip formation in turning operations. The insert is supplied with a hole featuring a cylindrical bore and a one-sided countersink (40°–60°) to ensure reliable location and clamping force in standard ISO-compatible toolholders. With a plate thickness of 3.97 mm and ISO form 16T308, the component offers a compact, rigid interface that helps to reduce vibration and improves surface finish on external and internal turning tasks.

Easy integration into ISO-based tool systems and selection guidance

The indexable insert fits common ISO toolholder systems when matched by form, clearance angle, tolerance class, attachment style, size and thickness. The product is delivered as part of a system that typically comprises the insert, a suitable outer holder or boring bar, a shim/locking set and replacement screws. As the item does not include a chipbreaker, selection of an appropriate chip control strategy and machining parameters is advised for intermittent cuts or when processing long, continuous swarf; consideration of feed, depth of cut and lubrication will preserve the PCD performance and ensure consistent component quality.

FAQ

Which materials is this insert best suited for?
The TPGW16T308 DX140 insert from Tungaloy is specifically designed for aluminium, other non-ferrous metals and abrasive non-metallic materials thanks to its PCD cutting layer and the DX140 grade.

Is the insert compatible with standard ISO toolholders?
Yes; the ISO designation 16T308 and the defined form, clearance angle and thickness ensure compatibility with ISO holders when the correct tolerance class and clamping hardware are used.

What is the benefit of the cylindrical hole with countersink?
The cylindrical hole combined with a one-sided countersink (40°–60°) provides secure location and reliable clamping, reducing movement under load and promoting consistent cutting geometry across multiple index changes.

Are chipbreakers available for this type?
This specific insert is supplied without a chipbreaker; chip control must therefore be managed by cutting parameters, toolholder geometry or by selecting an alternative grade with integrated chip control if required.

How does the PCD layer affect tool life and productivity?
The PCD cutting edge offers significantly longer life on abrasive or non-ferrous workpieces compared with conventional coatings, enabling higher cutting speeds and fewer tool changes, which increases overall production throughput.
