CNMG090404 T9225 — ISO indexable turning insert for robust steel turning (Tungaloy)

A CNMG090404 T9225 indexable turning insert engineered for medium-to-heavy steel turning, combining a tough CVD-coated carbide substrate with an 80° rhombic form for reliable chip control and long tool life.

• CVD-coated carbide for superior wear resistance
• Robust universal grade T9225 for steel turning
• ISO CNMG 09 rhombic, 80° geometry
• Double-sided chipbreaker; with cylindrical hole

Longer tool life through a tougher cutting grade

The CVD-coated carbide composition designated as T9225 is formulated for demanding turning tasks where variable engagement or slight interruptions occur. The CVD-coated surface provides a wear-resistant ceramic layer that slows flank and crater wear, while the substrate keeps sufficient toughness to resist chipping. As a result, batch runs and mixed-operation turning maintain consistent dimensions and surface finish, meaning fewer tool changes and lower per-part costs. The balanced combination of coating and substrate is particularly suited to machining steel components under medium-to-heavy cutting depths.

Secure clamping and ISO compatibility to speed up set-up

With the standard ISO CNMG090404 format and a rhombic 80° geometry, the insert fits a wide range of ISO turning holders; compatibility depends on form, relief angle, tolerance class, fastening and thickness. The insert features a cylindrical hole for precise seating and a double-sided chipbreaker, allowing both edges to be used before replacement. These design details reduce set-up time and ensure repeatable positioning, which supports leaner tool management and higher machine uptime. The listed corner radius 0.4 mm gives a compromise between edge strength and surface quality for general turning operations.

Practical performance and application guidance for productive turning

Designed as part of an ISO turning system, the insert works with a matching holder, underlay/clamp set and replacement screws to form a complete, serviceable tooling solution. The double-sided chipbreaker is optimised for stable chip formation when cutting steel, improving evacuation and helping to avoid built-up edge under varying conditions. Selecting the correct chipbreaker and feed conditions for the material and stability of the set-up will extend the number of machined parts per edge and improve process reliability. For workshops aiming to reduce variability, this solution offers an efficient balance of performance and robustness.

FAQ

What materials is this insert suitable for?
The CNMG090404 T9225 insert is intended primarily for steel machining in medium-to-heavy turning operations and is optimised for variable engagement.

How does the T9225 grade affect tool life?
The T9225 CVD-coated carbide offers enhanced wear resistance while retaining toughness, which improves edge life during interrupted cuts and variable conditions.

Is CNMG090404 compatible with standard holders?
Yes — the ISO CNMG090404 format and rhombic 80° geometry align with standard ISO turning holders; compatibility depends on holder form, clearance angle and fastening.

What is the benefit of the double-sided chipbreaker?
A double-sided chipbreaker provides two usable cutting edges per insert, improving economy and ensuring consistent chip control until the insert is rotated or replaced.

How does the corner radius influence machining results?
The 0.4 mm corner radius balances edge strength and surface finish: it delivers robust cutting edges while still producing acceptable surface quality for general turning tasks.
