CNMG 120404 T6215 turning insert – ISO CNMG 120404, Tungaloy

CNMG120404 T6215 is an ISO-standard indexable turning insert engineered for external and internal turning of rostfreier Stahl under stable to slightly interrupted cutting conditions.

• CVD-coated carbide grade T6215
• Intended for rostfreier Stahl machining
• ISO CNMG 120404 with 0.4 mm radius

Consistent performance for demanding rostfreier Stahl turning

The CVD-coated carbide composition and the T6215 wear-resistant grade provide a balance between toughness and abrasion resistance that is especially suited to rostfreier Stahl. The coating improves flank wear behaviour and extends edge life, which translates into fewer tool changes and higher productive uptime. As a result, process stability increases and surface finish quality becomes more predictable when using this indexable insert in stable machining conditions.

ISO compatibility reduces setup time and increases flexibility

Manufactured to the ISO CNMG 120404 specification, the insert fits a wide range of commercial external holders and boring bars; compatibility depends on form, relief angle, tolerance class, fixing, size and thickness. The rhombic plate geometry and standard dimensions simplify tool planning and allow fast replacement without complex reprogramming. This interchangeability supports lean tool management and reduces fixture and inventory complexity on the shop floor.

Improved chip control and repeatable results

Equipped with a double-sided chipbreaker, the insert guides chip flow to reduce entanglement and avoid surface damage. Better chip control lowers the risk of rework and increases process reliability across batch production runs. The predictable chip form and consistent cutting forces contribute to repeatable part tolerances and a more efficient downstream process.

Design and mounting for everyday production use

Key geometric details—0.4 mm corner radius, 4.76 mm thickness and 12 mm inscribed circle—combine with an 80° approach angle and a 0° relief to provide a stable cutting edge suitable for general turning tasks. The plate is supplied with a cylindrical hole, enabling secure clamping with standard screws, backing pads and clamping sets. In practice the system comprises the ISO insert, a matching external holder or boring bar, and the necessary clamping components for reliable mounting and consistent repeatability.
