DNMA 150408 TH10 Wendeplatten - Tungaloy

Combining the sharp TH10 uncoated carbide grade with an ISO rhombic form and a 0.8 mm corner radius results in low cutting forces and consistently clean surfaces for non‑ferrous turning; order the inserts via Metav Werkzeuge or consult our specialists for tailored machining recommendations.

DNMA150408 TH10 indexable turning insert (ISO 150408) by Tungaloy

A DNMA150408 TH10 rhombic insert engineered for external and internal turning, optimised for non‑ferrous materials and applications requiring a sharp, uncoated cutting edge.

• ISO‑standard rhombic insert, 55° cutting angle
• Sharp uncoated carbide grade TH10 for clean finishes
• Cylindrical hole for secure clamp mounting
• 0.8 mm corner radius for fine turning details

Consistent finishing and low cutting forces for turning operations

The DNMA150408 TH10 insert delivers reliable machining of non‑ferrous components thanks to its uncoated carbide composition and pointed geometry. The rhombic form with a 55° cutting angle reduces cutting resistance and supports better chip flow when working with softer metals, resulting in clean surface finishes and reduced burr formation. As an ISO‑compliant insert, it integrates into standard toolholding systems and helps maintain process stability across batch and single‑piece production. The combination of sharp edge geometry and an uncoated grade is especially advantageous where low cutting forces are required to avoid part deformation.

Secure seating and compatibility with common turning systems

Compatibility with a toolholder depends on form, relief angle, tolerance class, fastening style, size and thickness; the DNMA150408 is supplied with a cylindrical hole to allow positive locating and clamping in compatible seats. The 4.76 mm plate thickness and the standard ISO dimensions permit repeatable indexing and simple replacement during tool changeovers. Correct clamping and a matched holder minimise micro‑movement at the cutting edge, which translates directly into dimensional repeatability and tool life. Where holder reference surfaces and clamping torque are controlled, the insert provides a consistent cutting line and dependable mechanical stability.

Practical guidance for machining and selection

This insert is primarily intended for turning tasks in which an uncoated, sharp cutting edge benefits the process—typical applications include external and internal turning of aluminium alloys, copper alloys and other non‑ferrous workpieces. Because the insert is supplied without a chipbreaker, selecting the appropriate chip control strategy is important: match the grade and cutting parameters to workpiece material, workholding rigidity and depth of cut. For reduced tool pressure and optimised finishing, use stable clamping and modest depths of cut; when chatter or heavy engagement are expected, choose a holder and machining parameters that prioritise rigidity.

Material compatibility and efficiency considerations

Produced from high‑quality carbide, the DNMA150408 TH10 offers a balance between edge sharpness and sufficient wear resistance for non‑ferrous machining. The TH10 grade is tuned to provide low cutting forces and good surface quality where coatings are not required or where coating could negatively affect the cutting edge behaviour. For production environments focused on part quality and predictable process control, the insert delivers economical performance through repeatable indexing and straightforward tool management.

FAQ

Is this insert suitable for aluminium and other non‑ferrous alloys?
Yes. The DNMA150408 TH10 insert uses an uncoated TH10 carbide grade designed to produce low cutting forces and clean surface finishes when machining aluminium, copper alloys and similar non‑ferrous materials.

Will the insert fit my existing ISO toolholder?
Compatibility depends on form, relief angle, tolerance class, fastening and thickness; the ISO‑compliant DNMA150408 is intended for standard holders that accept rhombic ISO inserts with a cylindrical hole.

Does this insert include a chipbreaker for improved chip control?
No. The DNMA150408 TH10 is supplied without a chipbreaker; chip control should therefore be managed via toolpath strategy, cutting parameters and holder selection.

What are the key dimensions to check before ordering replacements?
Confirm the plate size (15 mm), thickness (4.76 mm), corner radius (0.8 mm), relief angle (0°) and the presence of a cylindrical hole when selecting the DNMA150408 TH10 for a specific holder.
