DNMG 150408 T9225 Turning Insert — Tungaloy (rhombic, CVD-coated carbide, 55°)

The DNMG150408 T9225 Tungaloy insert is an ISO-standard rhombic indexable insert designed for external and internal turning of steels, offering high toughness for interrupted cuts and variable engagement conditions.

• CVD-coated carbide universal grade T9225
• Rhombic 15 mm format, 55° lead angle
• 0.8 mm corner radius for robust edge strength
• Cylindrical-hole fixation, double-sided chipbreaker

Consistent performance for medium-to-heavy steel turning

The combination of a CVD-coated carbide substrate and the T9225 grade provides a balance of toughness and wear resistance that suits a wide range of steel turning tasks. The coating reduces flank wear and improves edge stability, while the substrate ensures resistance to chipping under variable cutting conditions. In practice, this means fewer unscheduled indexings and a steadier surface finish when machining bar and shaft workpieces. The 0.8 mm corner radius contributes to a stronger cutting edge and better load distribution during heavier depths of cut.

Designed for dependable holder compatibility and secure clamping

The insert follows ISO dimensions and the compatibility with toolholders is governed by form, clearance angle, tolerance class, fastening type, size and thickness. The rhombic form and 55° lead angle make the insert suitable for both external profiling and internal shoulder work, while the cylindrical hole and standard fixing ensure repeatable clamping. For shops integrating new tooling, the ISO designation simplifies procurement and reduces setup variability; selecting the matching external holder or boring bar and correct clamp is the decisive step for safe and precise use.

Productivity advantages and predictable tool life

Optimised for medium-to-heavy steel cutting, this insert’s geometry and double-sided chipbreaker help to control chips and maintain a consistent cutting force, which stabilises feeds and depths of cut. The result is improved process reliability and, over production runs, a favourable cost-per-component ratio. Where interrupted cuts occur, the enhanced toughness of the grade minimises edge degradation, supporting longer intervals between indexings and less operator intervention — practical benefits for batch production and mixed-series workflows.

Practical handling, indexing and system setup

The insert is double-sided and indexable, allowing reversal to a fresh cutting edge when the active edge becomes worn; this multiplies useful cutting edges per insert and reduces tooling stock on the shop floor. With a plate thickness of 4.76 mm and a standard 15 mm inscribed circle, replacements and inventory management are straightforward. Compatibility notes and the suggested system build include the ISO insert, a matching external holder or boring bar, a seating pad/clamp set and replacement screws — ensuring all components meet tolerance and fastening requirements for secure operation.

FAQ

What steels is this insert suited for?
The DNMG150408 T9225 insert is formulated as a robust universal grade for medium-to-heavy steel machining and performs well under variable engagement or slightly interrupted cuts.

How does the T9225 grade affect tool life?
Tungaloy’s T9225 grade combines toughness with wear resistance; the CVD coating reduces flank wear while the substrate resists chipping, resulting in predictable tool life under demanding steel turning conditions.

Is the insert reversible and how many cutting edges are available?
The insert is double-sided and indexable; reversing the insert provides additional cutting edges, multiplying usable edges per insert and lowering tooling cost per edge.

What holder features are required for correct compatibility?
Compatibility depends on the holder matching the ISO form, clearance angle, tolerance class, fastening method, size and thickness; choose a holder designed for DNMG inserts with cylindrical-hole clamping for secure fixation.

Can this insert be used for finishing passes?
While optimised for medium-to-heavy cuts, the geometry and coating can deliver acceptable surface finishes; for fine finishing, consider smaller corner radii and optimised feeds/slower cutting speeds.
