DNGA150404 LX21 indexable turning insert — ISO rhombic 55° form by Tungaloy

The DNGA150404 LX21 indexable insert is an ISO‑standard rhombic turning insert designed for external and internal turning, combining a cemented carbide body with the LX21 grade for a balance of wear resistance and toughness.

• DNGA rhombic form with 55° cutting angle
• LX21 grade for wear resistance and toughness
• 0.4 mm corner radius for accurate profiles
• Centre hole, cylindrical for secure clamping

High-performance cutting for sustained productivity

The DNGA150404 LX21 indexable insert is engineered to maintain a steady cutting edge under continuous turning loads. The LX21 grade supplements the substrate with a designed balance of wear resistance and toughness, which reduces frequent edge changes and supports longer uninterrupted production runs. For machining routines that prioritise cycle time and repeatability, the combination of cemented carbide substrate and LX21 conditioning delivers measurable improvements in tool life and process stability without compromising surface quality.

Precise geometry and straightforward integration

The rhombic plate geometry with a 55° cutting angle and 0° relief provides a reliable form for finish and medium turning operations, while the 0.4 mm corner radius ensures defined edge profiles. Being an ISO indexable design, the insert integrates with holders when the holder’s form, clearance, tolerance class, fastening method, size and thickness are matched. The 4.76 mm plate thickness and the cylindrical centre hole simplify secure mounting with standard clamping sets, supporting quick insert changes and minimal setup time in systematic production environments.

Grade characteristics that extend service intervals

The LX21 assorting of cutting characteristics is intended to combine edge stability with resistance to abrasive wear, which makes the insert suitable for a range of turning conditions where a balance between longevity and reliability is required. Choosing the correct chip control geometry and the LX21 grade according to the workpiece material and machining stability helps to reduce flank wear and maintain dimensional consistency. This targeted material‑grade approach supports predictable tool consumption and contributes to improved overall equipment effectiveness (OEE).

Practical handling and application guidance

For best results, pair the insert with an appropriate ISO holder and use the correct screw and clamping set for the cylindrical centre hole to ensure safe fixation. Compatibility with the chosen holder is determined by form, clearance, tolerance class, fastening, size and thickness; check these parameters before mounting. Where chip control is important, select a matching chipbreaker and adjust feeds and speeds to account for rig stiffness and material behaviour. Regular inspection of the cutting edge and adherence to recommended clamping torque will preserve the edge life and dimensional stability of the turned components.
