TNMG270612 T9225 — ISO turning insert, CVD‑coated carbide, 60° (Tungaloy)

TNMG270612 T9225 is an ISO‑standard triangular indexable insert engineered for external and internal turning of steel, offering a universal grade designed to cope with variable engagement and lightly interrupted cuts.

• CVD‑coated cemented carbide grade T9225
• Triangular 60° geometry for versatile turning
• 1.2 mm corner radius for durable edges
• Double‑sided chipbreaker for consistent chips

Durable grade and coating for reliable performance

The T9225 grade, a CVD‑coated cemented carbide, provides a balance between toughness and wear resistance suited to medium to heavy steel turning. The coating improves abrasion resistance at elevated cutting temperatures, while the substrate gives necessary fracture toughness when cuts are intermittent. The triangular form with a 60° included angle and a 1.2 mm corner radius gives a reproducible cutting edge geometry, helping to maintain consistent part tolerances and surface finish over longer runs. Compatibility with tooling systems depends on insert form, clearance angle, tolerance class, fastening method, size and thickness — factors that determine secure seating in a holder and repeatable positioning.

Practical system setup and selection advice

Designed as part of an ISO insert system, the package concept includes the insert itself together with a matching external holder or boring bar, correct seat/locator components and clamp set plus replacement screws where required. The double‑sided chipbreaker permits economical use of both cutting edges and supports predictable chip formation across varying feeds. When selecting a chipbreaker and grade, match the insert’s characteristics to the workpiece material and machining stability: the T9225 grade is recommended where toughness is prioritised—such as slightly interrupted cuts or mixed engagement—making it suitable for mixed batch production and repairs as well as serial turning.

Performance benefits that support productivity

Using an ISO triangular insert with CVD coating and a robust chip control geometry reduces unplanned tool changes and improves process security, which in turn increases productive cutting time per shift. The design supports improved surface quality and dimensional repeatability, especially on steel components where stable chip formation is essential. Together, these factors contribute to lower unit machining costs through longer tool life and fewer rejects. For operations seeking a pragmatic balance of durability and versatility, this insert offers a dependable solution for a wide range of turning tasks.

FAQ

What workpiece materials is this insert suitable for?
The Tungaloy TNMG270612 T9225 insert is tailored for steel machining and performs well in medium to heavy turning of steel, offering good chip control and toughness for slightly interrupted cuts.

How many cutting edges are available per insert?
As a double‑sided triangular insert, the TNMG270612 provides multiple usable cutting edges; both sides of the chipbreaker can be utilised before re‑indexing or replacement.

Can this insert be used for internal and external turning?
Yes, the ISO geometry and the insert’s dimensions allow use in both external holders and boring bars for internal turning, provided the holder matches the insert form and size.

What are the dimensional key data to check for holder compatibility?
Check insert size (27 mm), thickness (6.35 mm), included angle (60°), clearance angle (0°), corner radius (1.2 mm) and the presence of a cylindrical hole to ensure correct seating and fastening in the selected holder.

Does the T9225 grade suit interrupted cuts?
The T9225 grade is a robust universal grade designed to tolerate variable engagement and lightly interrupted cuts, delivering stable chip formation under changing conditions.
