DNMA150408 T505 ISO turning insert – CVD-coated carbide for turning | Tungaloy

The DNMA150408 T505 is an ISO-standard rhombic turning insert intended for economical external and internal turning of cast iron in general workshop and production settings.

• ISO-standard rhombic insert
• CVD-coated carbide grade T505
• Designed for economical cast iron machining
• 0° clearance / 0.8 mm nose radius

High-efficiency cutting with a CVD-coated grade for cast iron

The insert is manufactured in CVD-coated carbide grade T505, developed for economical cast iron machining where stable chip formation and extended edge life are priorities. The coating process builds a wear-resistant layer that reduces flank wear and supports consistent surface finish over long production runs. As a result, cycle times are shortened and tool change frequency is reduced, which benefits throughput on repetitive turning operations.

Geometry designed for repeatable precision and secure clamping

Rhombic geometry with a 55° included angle delivers a balanced compromise between strength and versatility for various turning tasks. The geometry is presented with 0° clearance, a 0.8 mm radius and a plate thickness of 4.76 mm, all contributing to predictable cutting behaviour and good edge stability. The cylindrical hole and the ISO contour ensure secure location and repeatable indexing in compatible holders, reducing set-up variability and improving part-to-part consistency.

System-ready insert that integrates into production workflows

Delivered as an ISO-standard insert, the component fits into a system comprised of a matching outer holder or boring bar, a support/clamp set and replacement screws. Selection of an appropriate chipbreaker and the T505 grade should follow the workpiece condition, cutting mode and machine stability; this allows adaptation to interrupted cuts or heavy roughing without compromising productivity. The insert’s simple replacement routine supports short tool-change times and predictable maintenance planning.

Durable performance that supports cost-effective turning

The combination of substrate and CVD coating provides a stable cutting edge and good resistance to built-up edge in grey and nodular cast iron. That stability translates directly into lower tooling costs per workpiece and more consistent part quality. For operations seeking reliable indexable tooling for cast-iron turning, the insert offers a pragmatic balance of productivity, wear resistance and ease of handling within established ISO tooling systems.

FAQ

Which materials is the insert suitable for?
The DNMA150408 T505 insert is engineered primarily for machining cast iron; the T505 grade and CVD coating support stable chip control and wear resistance in grey and nodular cast iron.

Is the insert compatible with my ISO holders?
Compatibility depends on form, clearance, tolerance class, fastening, size and thickness; the DNMA150408 follows ISO contours and is intended to fit holders designed for DNMA inserts.

Can this insert be used for interrupted cuts?
Yes; choosing the appropriate grade and, if available, a matching chipbreaker is recommended for interrupted cuts to maintain edge stability during shock loading.

How is the insert secured in the tool?
The insert is located and clamped via its cylindrical hole and the ISO seating; a matching clamp set and replacement screws complete the system for secure mounting.
