DCMT070208 T9225 Tungaloy turning insert — CVD-coated carbide, rhombic 07 for turning

The DCMT070208 T9225 is an ISO-format rhombic turning insert designed for external and internal turning of steels where interrupted cuts or varying engagement demand increased toughness.

• CVD-coated carbide for long tool life
• Universal T9225 grade for medium–heavy steel
• Rhombic 07 geometry with 7° relief angle
• With central hole and 40°–60° countersink

Consistent metal removal and predictable chip control for turning operations

The insert delivers stable chip formation and predictable tool life thanks to its CVD-coated carbide construction and the universal T9225 grade. In practice, this means more productive machining windows during longer tool cycles and fewer unplanned indexings, which supports steady workflow on production lathes. The one-sided chipbreaker is optimised for common turning feeds and helps evacuate chips reliably, reducing heat concentration at the cutting edge and improving surface consistency in serial work.

Robust grade selection for mixed and interrupted cutting conditions

Designed as a robust universal grade, the T9225 composition balances wear resistance and toughness to tolerate slightly interrupted cuts or variable engagement without premature edge failure. The result is fewer tool changes and a lower risk of process interruptions during the machining of alloyed and carbon steels. For engineers seeking economical throughput, the combination of the grade and the coated substrate provides a favourable cost-per-component ratio under medium-to-heavy cutting regimes.

Geometry and sizing that simplify holder selection and setup

The insert conforms to ISO designation and the rhombic 07 form, with a 7° relief angle, 55° included angle, 2.38 mm thickness and 0.8 mm corner radius; compatibility with the holder is determined by form, relief angle, tolerance class, fastening method, size and thickness. The central cylindrical hole with single-sided countersink (40°–60°) ensures secure clamping and repeatable seating, aiding stable cutting in both external and internal turning fixtures. When matching to an external holder or boring bar, verify these geometric parameters to ensure correct clamping and intended rake/lead relationships.

Practical benefits for workshop efficiency and process reliability

Using an ISO-format insert from a proven carbide grade reduces set-up variability and supports predictable scheduling. The coated surface reduces flank wear and contributes to consistent part finish over longer runs, while the specified 0.8 mm radius offers a compromise between edge strength and surface definition for turned profiles. For operations where material mix or intermittent cuts are common, this insert provides a pragmatic option that keeps machines running and pieces within tolerance more often.

FAQ

What materials is this insert suited for?
The insert is formulated for medium-to-heavy steel machining; the T9225 grade provides toughness for alloyed and carbon steels and handles slightly interrupted cuts.

How does the chipbreaker affect performance?
The one-sided chipbreaker promotes controlled chip formation under common turning feeds, improving evacuation and reducing heat at the cutting edge for more consistent surface finish.

Which geometric parameters must be matched to the holder?
Holders must match the ISO-format plate form, 7° relief angle, size 07, thickness 2.38 mm and the clamping method to ensure secure seating and reliable cutting performance.

Is this insert suitable for internal turning?
Yes, the rhombic 07 shape and secure central hole seating make the insert suitable for both external and internal turning when paired with an appropriate boring bar or internal holder.
