DNMG110404 T9225 Tungaloy insert — Turning insert (ISO DNMG 110404), rhombic 55°

The DNMG110404 T9225 is an ISO-standard rhombic turning insert engineered for medium-to-heavy steel turning, offering a double-sided chipbreaker and a cylindrical hole for secure fastening.

• CVD-coated carbide grade T9225
• ISO DNMG 110404 rhombic 55° geometry
• Double-sided chipbreaker, cylindrical hole
• Robust for medium-to-heavy steel turning

Consistent productivity through a tougher CVD-coated grade

The CVD-coated T9225 grade combines hardness and toughness to withstand slightly interrupted cuts and changing engagement conditions typical in heavy turning operations. This balance extends tool life and reduces index changes, which in turn supports steady production cycles and lower overall machining costs. The coating enhances wear resistance at elevated cutting temperatures, allowing more reliable cycle times under demanding workpiece materials such as medium-to-heavy steel. Operators benefit from fewer insert changes and more predictable tool performance on multi-shift production.

ISO-standard geometry for straightforward integration

Compatibility is ensured by the ISO designation and precise geometry: DNMG110404 format with a 55° rhombic approach, 11 mm size and 4.76 mm thickness. The 0.4 mm corner radius and a cylindrical hole provide defined seating and clamping for a wide range of external holders and boring bars. Because holder fit depends on form, clearance angle, tolerance class, fastening type, size and thickness, the ISO standard reduces uncertainty when specifying replacements or stocking inserts for diverse turning fixtures. This standardisation streamlines inventory and minimises downtime when inserts are changed.

Better chip control and surface quality for fewer reworks

The integrated double-sided chipbreaker promotes controlled chip formation and evacuation across a range of cutting conditions, contributing to improved surface finish with reduced manual finishing. The rhombic shape and chipformer geometry help break chips effectively even under variable feed or interrupted cuts, lowering the risk of workpiece damage and machine downtime. For customers seeking consistent batch-to-batch quality, these design features translate into higher first-pass yields and less post-process machining.

System thinking: matching insert, holder and process parameters

This ISO turning insert is intended for external and internal turning; the cutting system should comprise the insert, a matching outer holder or boring bar, an appropriate shim/clamp and the correct fixing screws. Select the chipbreaker and the T9225 grade according to workpiece material, machining strategy and machine rigidity to gain the full benefit of the insert’s toughness and wear resistance. For process planning, technical advisers can provide recommended speeds, feeds and depths of cut based on machine power and clamping stability, supporting safer, more efficient implementation in production environments.

FAQ

Which materials is this insert designed for? The DNMG110404 T9225 insert is optimised for medium-to-heavy steel turning; the CVD-coated carbide construction provides wear resistance and toughness for demanding steel machining.

What are the key geometry and size details of the insert? The insert follows the DNMG110404 ISO format with a 55° rhombic shape, 11 mm size, 4.76 mm thickness and a 0.4 mm corner radius; it is supplied with a cylindrical hole for fastening.

Is the insert reversible and how many cutting edges are available? Yes — the double-sided design provides two indexed cutting edges per side, enabling multiple repositions before replacement and improving cost efficiency per insert.

How does the chipbreaker affect machining? The double-sided chipbreaker is designed for stable chip formation across varying cutting conditions, reducing the likelihood of long chips and supporting improved surface quality and process reliability.

What should be considered when matching the insert to a holder? Ensure holder compatibility by checking form, clearance angle (0° for this insert), tolerance class, fastening method, size and thickness; correct matching secures seating and repeatable performance.
