CNMG190616 T9225 — Tungaloy turning indexable insert, 80° rhombic, 1.6 mm radius

CNMG190616 T9225 is an ISO‑standard rhombic insert for turning, designed for medium to heavy steel machining where toughness, wear resistance and stable chip control are required

• ISO‑standard CNMG geometry
• CVD‑coated carbide grade T9225
• Double‑sided chipbreaker for stable chips
• 80° rhombic insert with 1.6 mm radius

High cutting reliability for medium to heavy steel turning

The T9225 grade is a CVD‑coated carbide designed as a robust universal solution for medium to heavy steel machining and light interruptions. Its composition prioritises toughness over extreme hardness, which reduces the risk of chipping under variable engagement and interrupted cuts. As a result, production runs benefit from more consistent tool life and fewer unexpected tool changes, improving overall machine uptime and process stability.

Fast integration into ISO tool systems and predictable setup

The CNMG190616 geometry follows ISO standards and is compatible with common external holders and boring bars when form, clearance, tolerance class, fastening method, size and thickness match. The 80° rhombic shape and 6.35 mm thickness provide a solid clamping interface; the insert is supplied with a cylindrical hole, permitting secure fastening. A 0° clearance angle and a double‑sided design give two usable cutting edges per index, simplifying inventory management and reducing cost per usable edge.

Improved productivity and surface consistency with controlled chip formation

A double‑sided chipbreaker on this insert supports reliable chip control across a range of feeds and depths of cut, which contributes directly to surface quality and process security. The 1.6 mm corner radius balances edge strength and finish: it increases resistance to edge wear in heavy cuts while still enabling acceptable surface integrity. Combined with the CVD coating, this results in extended service life under demanding conditions and predictable tool performance over long series production.

Practical benefits for workshop and production planning

Using an ISO indexable insert with established geometry reduces setup variations between machines and operators. The rhombic form factor and standard dimensions mean holders are widely available, and the reversible nature of the insert yields quick edge changes and lower per‑edge cost. For operations facing mixed or interrupted cuts, the robust grade and chip control minimise downtime caused by edge failure and stabilise component quality.

FAQ

Is this insert suitable for interrupted cuts in steel?
Yes. The Tungaloy CNMG190616 T9225 insert is formulated for medium to heavy steel machining and offers increased toughness for lightly interrupted cuts, improving edge reliability.

What holding criteria ensure compatibility with standard toolholders?
Compatibility depends on matching the CNMG form, the thickness (6.35 mm), the size (19 mm), the clearance angle and the fastening style; the cylindrical hole supports secure clamping.

How many usable edges does the insert provide?
The insert is double‑sided and reversible, offering two usable cutting edges per index, which helps reduce tooling costs and inventory.

What role does the 1.6 mm corner radius play in machining?
A 1.6 mm corner radius increases edge strength for heavy cuts and intermittent conditions while maintaining acceptable surface finish, balancing life and quality.
