DCMT 070208 NS9530 Tungaloy – DCMT indexable turning insert for finishing

The DCMT070208 NS9530 Tungaloy is an ISO rhombic indexable turning insert designed for precision external and internal turning on steel, optimised for continuous cuts and small depths of cut.

• ISO rhombic DCMT 070208 geometry
• NS9530 uncoated cermet finishing grade
• 0.8 mm corner radius for fine finish
• Single-sided chipbreaker, with hole and countersink

High-quality finishing performance for steel components

The DCMT070208 NS9530 insert is a finishing-grade, uncoated cermet designed to deliver a superior surface finish and reduced cutting forces during light-depth passes. The NS9530 grade provides a sharp cutting edge that is particularly effective on steel in continuous cutting conditions, enabling consistent part quality and reducing subsequent machining or polishing steps. By favouring small feedrates and controlled cutting speeds, this insert helps achieve tight surface tolerances while lowering the risk of built-up edge. The result is improved process efficiency and fewer rework cycles in routine turning operations.

Predictable fit and secure clamping in ISO systems

Compatibility with the clamping system is governed by geometry, ISO designation, relief angle, tolerance class, size and thickness; the DCMT form and 7° relief angle ensure a standard interface with matching indexable holders. The insert’s 2.38 mm thickness and central hole with a cylindrical hole plus one-sided countersink (40°–60°) provide secure fastening and repeatable positioning in approved holders. This standardisation reduces setup variability, shortens changeover time and supports stable toolpaths in production environments where reproducibility is essential for throughput and part conformity.

Efficient chip control and reduced machining risk

Equipped with a single-sided chipbreaker and a central fastening hole, this insert promotes reliable chip evacuation during finishing cuts. The chipforming geometry is tuned for low‑volume chips under small depths of cut, which lowers the likelihood of chip entanglement and prolongs uninterrupted running time. Coupled with a 0.8 mm corner radius, the insert balances edge strength and cutting delicacy, improving edge life while preserving fine surface quality. Selecting the matching chipbreaker and grade according to workpiece stability and cutting strategy yields measurable gains in productivity.

Practical applications and workshop advantages

This rhombic DCMT insert is intended for both external and internal turning where a high surface standard is required. Typical use cases include precision shaft turning, finishing bores and small passes on turned faces in steel components. The geometry and grade combination reduce the need for secondary finishing and support leaner machining sequences. For mixed production runs, the standard ISO form simplifies tool inventory management and allows quick replacement without extensive requalification, contributing to lower total machining costs.
