DNMG 150404 NS520 — Tungaloy ISO indexable turning insert for finishing, 55°

DNMG 150404 NS520 is an ISO rhombic indexable insert intended for turning applications, optimised for finishing to light machining of steel with a focus on surface quality and dimensional stability

• ISO-compatible rhombic insert
• Optimised NS520 cermet grade
• Double-sided chipbreaker design
• 0° clearance, 0.4 mm corner radius

Superior surface quality and repeatable dimensional control

The NS520 cermet composition delivers a fine, wear-resistant cutting edge that supports exceptionally consistent surface finish and dimensional accuracy during finishing passes. Cermet grades are engineered for minimal built-up edge and stable flank wear, which translates into fewer interrupted batches and more predictable part quality. For operations where tight tolerances and high-quality external surfaces are required, this insert provides a balance between low cutting forces and sustained edge integrity.

Lower tooling cost through double-sided economy and chip control

A double-sided design with integrated chipbreaker reduces the number of inserts required per job and optimises chip evacuation for stable cutting conditions. The built-in chip control improves process reliability when machining medium-to-high carbon steels in finishing to light machining modes, thereby lowering tooling consumption and increasing productive cutting time. The result is a measurable impact on unit costs across serial production or short-run batches.

Reliable fit and reduced setup risk with ISO conformity

The ISO designation simplifies tool selection and holder matching: compatibility is determined by insert form, relief angle, tolerance class, fastening style, size and thickness. The DNMG150404 form and standard geometry reduce the risk of mismatches in the toolholder, making setup faster and less error-prone. Where consistency across multiple centres is essential, ISO conformity helps maintain uniform clamping and repeatable cutting performance.

Key dimensions that influence cutting behaviour

Corner radius and insert geometry directly affect feed, finish and edge strength. A 0.4 mm corner radius provides the blend of modest edge strength and fine finish desirable in finishing operations, while a 4.76 mm thickness contributes to stable clamping and reduced vibration. The 55° approach angle is suitable for external turning tasks, balancing radial cutting forces and surface integrity. These measurable parameters make it straightforward to select cutting parameters and predict process outcomes.

Material system and application advantages

Built on a carbide substrate and specified as cermet or coated cermet, the grade supports a broad range of steel applications in finishing to light machining. Cermet grades offer superior oxidation resistance at moderate cutting temperatures and typically produce improved workpiece finish compared with conventional carbides. Combined with the Tungaloy manufacturing standards, the insert is aimed at users seeking reliable finishing performance with consistent wear characteristics.
