DNMG150404 T5125 DNMG turning insert – Tungaloy, CVD-coated carbide, 55°

The DNMG150404 T5125 is an ISO-standard rhombic indexable insert for external and internal turning, designed for interrupted cuts in cast iron and less stable machining conditions.

• ISO-standard rhombic turning insert
• CVD-coated carbide for robust cutting
• Double-sided chipbreaker for cost efficiency
• Cylindrical-hole, 55° geometry for stable clamping

Consistent performance for interrupted cast-iron machining

The combination of a CVD-coated carbide substrate and the T5125 grade delivers a balance of toughness and wear resistance that is especially suited to interrupted cutting conditions. The coating supports surface integrity while the substrate resists chipping when cutting cast iron; this reduces unexpected tool failures and extends in-process intervals. As a result, the insert provides a measurable improvement in process stability and fewer tool changes, which supports uninterrupted production runs and predictable machining cycles.

Secure fit and straightforward integration into ISO systems

With its rhombic 55° geometry and a cylindrical locating hole, this insert is compatible with common ISO turning holders when matched for form, relief angle and tolerance class. The 15 mm inscribed circle and 4.76 mm thickness ensure a solid seat in the toolholder, while the 0.4 mm corner radius gives a compromise between edge strength and surface finish. The double-sided design allows rotation to a fresh cutting edge, improving cost efficiency by doubling the available edge life compared with single-sided alternatives.

Chip control and economic machining benefits

The double-sided chipbreaker is engineered to manage chips consistently in cast-iron applications, reducing re-cutting and improving surface quality. The grade’s toughness helps absorb the shocks of interrupted cuts, decreasing the likelihood of edge breakage and downtime. Explained simply, the CVD coating forms a thin, hard layer that reduces abrasive wear, while the tougher substrate beneath resists mechanical impact — together delivering longer life and lower total machining cost per component without sacrificing component quality.

FAQ

What materials is this insert suitable for?
The DNMG150404 T5125 insert is specified for cast iron applications and performs well in interrupted cuts; the CVD coating and tougher grade support machining in less stable conditions.

Is the insert compatible with standard ISO holders?
Yes, the insert follows ISO dimensions for DNMG 150404 geometry and fits holders that accept rhombic 55° inserts with a cylindrical locating hole when the holder matches the listed thickness and tolerance class.

How does the T5125 grade affect tool life?
The T5125 grade combines a tough substrate with a CVD coating to resist chipping during interrupted cuts, which typically extends usable edge life and reduces the frequency of tool changes.

Can the insert be rotated or indexed?
The insert is double-sided, allowing rotation to a fresh cutting edge; this effectively doubles the available edges and increases cost efficiency for batch production.

What chip control can be expected with this insert?
The double-sided chipbreaker is designed to produce controlled chip formation in cast iron turning, supporting better surface finish and safer swarf handling.
