CNMG 090412 T9225 ISO turning insert for turning — Tungaloy

CNMG 090412 T9225 is an ISO‑standard indexable turning insert designed for medium to heavy steel machining with compatibility for standard ISO holders

• CVD-coated carbide grade T9225
• For medium to heavy steel machining
• Rhombic CNMG shape with 80° lead angle
• Double-sided chipbreaker, cylindrical hole
• 1.2 mm corner radius for stable cutting

Improved productivity through a robust cutting grade

The CVD-coated T9225 grade combines abrasion resistance with enhanced toughness to cope with changing engagement conditions. As a carbide insert engineered for medium-to-heavy steel machining, it offers longer tool life compared with uncoated grades and reduces downtime for index changes. The hardened coating supports higher cutting speeds and steadier material removal, which translates into fewer interventions and more predictable cycle times on turning centres and lathes. The result is measurable process efficiency and lower part cost per component.

Secure edge and reliable chip control for interrupted cuts

A double-sided chipbreaker paired with a 1.2 mm corner radius stabilises the cutting edge and controls chip formation during heavy or slightly interrupted cuts. The rhombic CNMG form with an 80° lead angle provides a balance between radial strength and accessibility for shoulder and turning operations. This combination reduces vibration and protects the cutting edge against shock loads, helping to preserve surface finish and dimensional consistency when machining tougher steels or variable feeds.

Straightforward integration and ISO compatibility

The insert conforms to ISO geometry, with a 4.76 mm thickness, size 09 seating, and a cylindrical central hole for positive clamping. Compatibility to a holder is determined by form, relief angle, tolerance class, mounting and plate size — following ISO standards ensures interchangeability with common external holders and boring bars. The indexed, double‑sided design allows cost-efficient use of both edges, and the clear specification of relief angle (0°) and lead angle supports process planning and fixture selection on CNC lathes and turning centres. For uncertain applications, technical data from the supplier can be used to match holder geometry and cutting parameters.

FAQ

What materials is this insert intended for?
The CNMG090412 T9225 insert is specified for medium‑to‑heavy steel machining and the T9225 grade is selected for robustness under changing engagement conditions.

Is the insert compatible with standard ISO holders?
Yes, the ISO geometry (CNMG 09 size, 4.76 mm thickness, cylindrical hole) ensures compatibility with holders and boring bars designed for ISO indexable inserts.

How does the double-sided chipbreaker benefit production?
The double-sided chipbreaker provides repeatable chip control and edge protection, reducing vibration and improving surface finish during interrupted or heavy cuts.

Can both cutting edges be used?
Yes, the indexable design allows rotation to a fresh cutting edge, which doubles the usable life per insert compared with a single‑edged alternative.

What are the defining geometrical values to check for holder matching?
Key values are the CNMG form, size 09, 4.76 mm thickness, 1.2 mm corner radius and the 80° lead angle; these determine fit and seating in the chosen holder.
