DNMG 150412 T9235 indexable turning insert by Tungaloy — CVD-coated carbide, rhombic 55° geometry

DNMG150412 T9235 is a rhombic indexable insert designed for external and internal turning operations where stability and chip control matter

• CVD-coated carbide grade T9235
• Rhombic DNMG geometry, 55° lead angle
• Double-sided chipbreaker, cylindrical hole for clamping
• Suited for interrupted cuts and unstable conditions

Precision and compatibility for dependable turning results

The DNMG150412 geometry combines a 55° lead angle with a 0° clearance to offer predictable contact conditions and repeatable seating in compatible toolholders. As an ISO-standard indexable turning insert, it is compatible where form, clearance angle, tolerance class, fastening method, size and thickness match the holder specification. This predictability reduces setup time and allows planning of toolpaths and feeds around a known contact geometry, which supports consistent production output.

Durable CVD-coated carbide for steel turning under stress

The carbides in grade T9235 are CVD-coated and formulated for toughness rather than extreme cutting speed; they resist chipping during interrupted cuts and perform well in less rigid setups. This means the cutting edge retains integrity when encountering varying cross-sections or built-in interruptions. By prioritising edge robustness, the insert extends effective tool life in demanding steel applications and reduces unscheduled tool changes, contributing to a steadier machining cycle.

Improved chip control and secure clamping minimise rework

The double-sided chipbreaker and rhombic profile promote controlled chip formation and evacuation on both cutting edges, helping to avoid snaring or irregular chip shapes that can damage components or interfere with automation. The cylindrical hole and corresponding fastening method ensure a stable seat and accurate repeatability when indexing the second cutting edge. Together, these features reduce the risk of redeployment errors and support cleaner finishing passes with fewer manual interventions.

Application guidance: choose the right setup for best economy

Select a matching external holder or boring bar and the correct insert grade for the workpiece and machining stability. For roughing with interrupted sections, the T9235 grade is recommended at moderate cutting speeds with conservative feeds to exploit its toughness. For finishing, consider the holder rigidity and balance feed and speed to maintain surface quality without compromising edge life. The system approach — insert, holder, shim and clamping screw — is key to repeatable performance and lower per-part machining costs.

FAQ

What materials is this insert intended for?
The DNMG150412 T9235 insert is intended primarily for steel machining; the T9235 grade is a tough CVD-coated carbide formulated for steel and for conditions with interrupted cuts.

Can this insert be used for both external and internal turning?
Yes, the rhombic DNMG150412 geometry suits both external and internal turning when paired with the appropriate holder and correct clamping components.

How does the double-sided chipbreaker help in production?
The double-sided chipbreaker on the insert promotes consistent chip formation on both edges, improving evacuation and reducing the likelihood of chip-induced surface defects during turning.

What should be considered when mounting the insert?
Use a holder that matches the DNMG form, 55° lead angle and the tolerance class for secure seating; the cylindrical hole and clamping system ensure accurate repeatability when indexing the second cutting edge.

Is the T9235 grade suitable for unstable machining conditions?
Yes, T9235 is a tough CVD-coated carbide grade selected for lower cutting speeds in unstable setups and for resistence against edge chipping during interrupted cuts.
