DNGN150408 LX10 — indexable turning insert for turning, 55° rhombic, Tungaloy

The DNGN150408 LX10 is an ISO‑standard rhombic indexable insert intended for external and internal turning, engineered to balance wear resistance and cutting-edge stability for robust production machining.

• ISO‑standard rhombic insert, 55° cutting angle
• Tungaloy LX10 grade for wear resistance and toughness
• 0.8 mm corner radius for controlled edge strength
• 4.76 mm plate thickness for secure clamping
• No chipbreaker design for flexible application

Improve productivity with a robust cutting geometry

The indexable insert delivers a predictable cutting performance through its 55° cutting geometry and 0.8 mm corner radius, which together provide a compromise between edge strength and form accuracy. The geometry is tailored for both finishing and medium‑duty roughing when process stability is sufficient; the modest corner radius reduces the risk of built‑up edge and helps maintain repeatable surface quality. As an ISO‑standard component, the insert contributes to shorter changeover times and consistent results across compatible toolholders.

Clear guidance on holder compatibility and mounting

Compatibility with toolholders is governed by the insert shape, clearance angle (0°), tolerance class, fastening method, size and thickness. The rhombic form and 4.76 mm plate thickness ensure positive clamping in appropriately matched external holders or boring bars. The absence of a mounting hole means clamping relies on the boss and screw system of the holder; secure clamping reduces vibration and supports tool life, while correct torque and seat cleanliness are essential to achieve the rated performance.

LX10 carbide grade explained for reliable tool life

The LX10 designation denotes Tungaloy’s carbide grade, formulated to offer a balance of wear resistance and toughness suitable for general turning tasks. The cemented carbide composition provides thermal stability and a durable cutting edge under typical production feeds and speeds. Selecting LX10 complements the insert geometry where moderate cutting forces and interrupted cuts are encountered; the grade aims to reduce flank wear while maintaining a stable cutting edge for repeatable component quality.

Practical machining recommendations and selection criteria

For best results, choose a chipbreaker and grade that match the workpiece material, machining method and machine rigidity; this insert is supplied without a chipbreaker, offering flexibility when customised chip control is required. Where heavy interruption or unstable setups occur, a larger corner radius and a more tolerant holder arrangement are advisable. In batch production, pairing the insert with a holder that provides strong support and minimal overhang will help to extend tool life and maintain surface finish consistency.

FAQ

What is the primary application for this insert?
The insert is designed for turning operations; the DNGN150408 LX10 indexable insert (SKU 6852045-Tungaloy) suits both external and internal turning where the geometry and grade match the process.

How does the 0° clearance angle affect use?
A 0° clearance angle offers a specific cutting orientation that must be matched by the toolholder and setup; correct matching ensures proper rake and chip flow for the intended turning task.

Is there a chipbreaker on the insert?
This grade is supplied without a chipbreaker, allowing the choice of holder and external chip control measures to be adapted to the workpiece and machining strategy.

Which materials is the LX10 grade suitable for?
The LX10 carbide grade is formulated to balance wear resistance and toughness for a broad range of turning tasks; selection should be based on workpiece material, feed, speed and stability requirements.

How should the insert be clamped?
Secure clamping in an ISO‑compatible holder with the correct seat and screw torque is essential; the absence of a hole means the clamping relies on the holder’s boss and screw system and on a precise seat.
