DNMG 110412 T9225 — Tungaloy indexable turning insert (CVD‑coated carbide, 55°)

DNMG110412 T9225 is an ISO‑specified, rhombic indexable insert designed for robust external and internal turning in varied steel applications

• Rhombic DNMG geometry, 55° approach angle
• CVD‑coated carbide grade T9225 for steel
• Double‑sided chipbreaker, versatile cutting
• Compatible with standard ISO holders

Improved productivity for medium‑to‑heavy steel turning

The CVD‑coated T9225 grade delivers a balance of toughness and wear resistance tailored for medium‑to‑heavy steel machining where changing engagement conditions or slightly interrupted cuts require additional edge strength. The coating provides a hard, temperature‑resistant surface while the carbide substrate maintains core toughness; this combination reduces flank wear and extends tool life under demanding operating parameters. As an ISO‑formed indexable insert, the geometry and coating together enable stable cut formation and consistent surface finish with fewer tool changes.

Secure mounting and universal ISO compatibility

The rhombic DNMG geometry with a 55° approach angle and a cylindrical locating hole ensures precise positioning and reliable clamping in standard ISO external holders or boring bars. The 0° clearance specification and the specified plate thickness support repeatable set‑ups and predictable cutting forces, which cuts down on secondary adjustments and machine downtime. The reversible, double‑sided design allows economical use of both cutting edges before replacement, enhancing uptime and simplifying inventory management for production workshops.

Confidence in chip control and process stability

Equipped with a double‑sided chipbreaker, the insert promotes stable chip formation across a range of feeds and depths of cut, helping to avoid built‑up edge and reducing the risk of surface damage. The moderate corner radius supports finishing and semi‑roughing passes while preserving edge strength for interrupted cuts. Backed by Tungaloy’s material and coating expertise, this insert suits manufacturers seeking a blend of durability and consistent performance under variable cutting conditions, contributing to predictable cycle times and fewer unexpected interventions.

FAQ

What materials is this insert suitable for?
The Tungaloy DNMG110412 T9225 insert is engineered primarily for steel machining, offering good performance in medium‑to‑heavy turning where increased toughness is required.

Can the insert handle interrupted cuts?
Yes. The T9225 grade combines a tough carbide substrate with a CVD coating, providing the necessary edge strength and resilience for slightly interrupted cuts.

How does the chipbreaker affect performance?
The double‑sided chipbreaker promotes controlled chip formation and evacuation, improving surface finish and reducing the risk of chip entanglement during continuous and semi‑continuous turning.

Is the insert reversible and how many cutting edges are available?
The DNMG geometry is double‑sided and reversible, offering two usable cutting edges per side depending on the holder and orientation, which supports cost‑effective tool usage.

What determines compatibility with a toolholder?
Compatibility is given by the ISO form, relief angle, tolerance class, fastening method, insert size and thickness; the DNMG110412 designation ensures conformity with standard DNMG holders.
