DNMG 110412 T9225 turning insert by Tungaloy — ISO 55° rhombic CVD-coated carbide

DNMG110412 T9225 is an ISO-standard indexable insert designed for external and internal turning; the rhombic 55° geometry and universal T9225 grade suit variable engagement and interrupted cuts

• CVD-coated carbide T9225 for robust cutting
• 55° rhombic geometry for versatile turning
• 1.2 mm corner radius for stable edge strength
• Double-sided chipbreaker, cylindrical hole for secure fixing

Dependable cutting performance for medium to heavy steel turning

The CVD-coated T9225 carbide grade provides a balanced combination of toughness and wear resistance that is engineered for the demands of steel machining under changing engagement conditions. The coating improves resistance to abrasive wear while the substrate retains enough toughness for light interruptions and variable cutting depths. As a result, the insert delivers consistent edge life and predictable replacement intervals, which supports production planning and reduces unexpected tool changes.

Geometry and dimensions that simplify holder compatibility

A 55° rhombic shape with a 1.2 mm corner radius and 0° relief angle offers a flexible compromise between chip control and profile accuracy. The plate thickness of 4.76 mm and the inscribed circle size 11 are standard ISO dimensions; compatibility with a chosen holder depends on form, relief angle, tolerance class, clamping method and plate thickness. Using inserts with standard ISO interfaces ensures rapid replacement in existing indexable systems and keeps machine downtime to a minimum.

System benefits that cut processing costs

The double-sided chipbreaker and cylindrical hole enhance clamping stability and allow two usable cutting edges per insert, lowering cost per edge. Integrated into a conventional indexable system—insert, matching external holder or boring bar, shim and clamping set—this solution streamlines inventory and simplifies logistics. Reliable chip control and repeatable seating reduce scrap and rework, contributing to measurable improvements in line throughput and tool cost efficiency.

Choosing the right chipbreaker and application tips

Select a chipbreaker and grade that match workpiece material, process stability and cutting parameters; the universal nature of this grade makes it particularly suitable for batches where conditions vary. For interrupted cuts or less rigid setups, prefer conservative feeds and make use of the 1.2 mm radius to protect the edge. For higher productivity, tune cutting data gradually while monitoring surface finish and edge wear to find the optimal balance between metal removal rate and tool life.
