DNMG 150404 T9235 indexable turning insert by Tungaloy — 55° rhombic geometry, CVD-coated carbide

The DNMG150404 T9235 is an ISO-standard indexable turning insert designed for external and internal turning, offering a tough CVD-coated carbide grade suited to lower cutting speeds and interrupted cuts.

• CVD-coated carbide grade T9235
• Rhombic 55° geometry, 0° rake angle
• Double-sided insert with cylindrical hole
• 0.4 mm corner radius for versatile profiles

Proven toughness for interrupted turning and unstable conditions

The included grade, T9235, is a CVD-coated carbide formulated to provide toughness under interrupted cuts and unstable machining conditions. This makes the insert particularly suitable for machining steel, where sudden impacts and variable chip loads can cause chipping with harder, more brittle grades. The CVD coating enhances flank and crater wear resistance while the carbide substrate absorbs shock, resulting in a more reliable cycle time and fewer unexpected tool changes. For production environments where process stability matters, this combination supports consistent part quality and reduced scrap rates.

ISO standardisation ensures secure holder compatibility and fast setup

Being part of the ISO turning insert family, the geometry and dimensions follow standard conventions so that compatibility with the toolholder is determined by form, relief angle, tolerance class, clamping method, size and thickness. This standardisation simplifies inventory decisions: the same insert geometry fits a broad range of holders designed for DNMG-style plates. The rhombic 55° geometry provides a balance between strength and accessibility, enabling effective external and internal turning while keeping tool changeovers straightforward and predictable.

Durable coating and geometry translate into measurable workshop benefits

The CVD-coated surface reduces abrasive wear and increases tool life in many steel applications, while the 0° rake angle and 0.4 mm corner radius create a stable cutting edge that helps maintain dimensional accuracy over longer runs. The double-sided, indexable design halves the effective cost per cutting edge compared with single-use inserts and reduces downtime for replacements. These technical characteristics together offer a tangible improvement in machining efficiency—less rework, fewer clamp adjustments and a better cost-per-part metric in mixed-batch production.

Practical handling and mounting for efficient production flow

The insert features a cylindrical locating hole and is available with standard 4.76 mm thickness and a nominal size of 15 mm, allowing secure clamping and repeatable positioning in compatible holders. The double-sided arrangement and ISO form make reindexing simple, so maintenance crews spend less time handling toolstock and more time keeping machines productive. When uncertainty arises about holder compatibility or application specifics, Metav Werkzeuge can advise on the correct clamping set, underlay and replacement screws for an optimized tool system.

FAQ

Is this insert suitable for steel machining? Yes. The T9235 grade is a tough CVD-coated carbide designed specifically for steel machining at lower cutting speeds and in conditions with unstable or interrupted cuts, offering reduced chipping risk.

How does ISO standardisation affect holder compatibility? ISO standardisation means compatibility is defined by form, relief angle, tolerance class, clamping method, size and thickness; using the DNMG150404 form ensures a wide range of compatible holders and predictable mounting.

Can the insert be re-indexed to use multiple edges? Yes. This is a double-sided indexable insert, allowing the use of multiple cutting edges before disposal, which improves cost-efficiency per edge.

What does the 55° rhombic geometry mean for machining? A 55° rhombic geometry offers a compromise between edge strength and tool access, making it versatile for both external and internal turning while maintaining rigidity for interrupted cuts.
