DNMG150616 T9225 Tungaloy turning insert — CVD-coated carbide, 55° rhombic

A DNMG150616 T9225 Tungaloy turning insert designed for external and internal turning, offering a robust universal grade for interrupted cuts and variable engagement in steel machining

• CVD-coated carbide for robust performance
• Universally tough grade T9225 for steel machining
• 55° rhombic geometry for standard holders
• Double-sided chipbreaker with cylindrical hole

Predictable performance through a robust substrate

The insert is built on a CVD-coated carbide substrate that combines wear resistance with required toughness for medium-to-heavy machining. This T9225 grade is formulated to resist edge chipping under varying cutting conditions, which results in longer tool life and fewer indexing cycles. The double-sided design ensures two cutting edges per index, reducing tooling costs per part and enabling consistent component quality over longer production runs. As a result, cycle-time stability and process reliability are improved, making the insert a pragmatic choice for batch and continuous turning operations.

Straightforward compatibility with ISO turning systems

Compatibility of an insert depends on form, relief angle, tolerance class, fastening and dimensions. The rhombic 55° geometry and dimensions (15 mm size, 6.35 mm thickness, 1.6 mm corner radius) allow simple integration into standard ISO external holders and boring bars. The presence of a cylindrical hole supports secure clamping and repeatable seating, while the 0° relief angle provides stable engagement for outer and inner diameters. Clear specification of these parameters reduces setup time and helps ensure the cutting edge sits correctly in the holder, improving runout behaviour and surface finish without complex reconfiguration.

Practical guidance for machining and process gains

Select the double-sided chipbreaker and the universal grade when facing mixed engagement conditions or slightly interrupted cuts; this combination balances chip control and edge toughness. For steel machining, modest feeds and cutting speeds tuned to the T9225 recommendation yield an optimal balance between surface integrity and tool economy. The insert’s geometry supports controlled chip flow and reduces heat concentration at the cutting edge, which benefits batch consistency and minimises scrap rates. Where higher productivity is required, pairing this insert with a rigid holder and optimised coolant strategy increases achievable metal removal rates while maintaining surface quality.

Why this insert benefits workshop productivity

By offering a combination of a resilient carbides substrate, versatile chip control and standard ISO dimensions, this indexable solution reduces inventory complexity and supports a broad range of turning tasks. The result is lower per-part tooling costs, fewer downtime interruptions for indexing and more predictable production output. For operations seeking a balance of process security and economical cutting performance, the configuration described here delivers measurable improvements in throughput and repeatability.

FAQ

Is this insert suitable for interrupted cuts in steel?
Yes. The DNMG150616 T9225 insert uses a resilient CVD-coated carbide grade that is intended for medium-to-heavy steel machining and performs well under lightly interrupted cutting conditions.

How is the insert secured in the holder?
The insert features a cylindrical hole for positive clamping and is compatible with ISO-standard clamping systems when the holder matches the DNMG form, size and thickness.

How many usable edges does the insert provide?
The rhombic, double-sided design offers two indexed cutting edges, enabling economical use of each insert before replacement.

Which dimensions are critical for holder selection?
Key dimensions include the 15 mm size, 6.35 mm thickness and the 55° rhombic form; these determine seat geometry, clearance and clamping fit in ISO holders.

Can the insert be used for internal turning as well as external?
Yes. The geometry and relief angle support both external and internal turning applications when used with an appropriate boring bar or internal holder.
