CNMG190612 T9225 ISO turning insert — rhombic 80° geometry by Tungaloy

CNMG190612 T9225 is an ISO‑format rhombic turning insert designed for medium to heavy steel machining and interrupted cuts

• ISO rhombic CNMG 80° geometry
• CVD-coated carbide T9225 grade
• Double-sided chipbreaker, with hole
• 1.2 mm corner radius, 6.35 mm thick

Greater productivity through a robust universal grade

The combination of a CVD‑coated carbide substrate and the T9225 grade yields a versatile, wear‑resistant cutting edge tailored for steel turning under fluctuating engagement. This composition offers enhanced toughness where interrupted cuts or variable feed conditions occur, reducing flank wear and the frequency of tool changes. The result is a measurable improvement in process stability and effective tool life, which supports higher parts-per‑shift output and lower overall machining costs. The rhombic geometry contributes to reliable cutting action and predictable finish without sacrificing edge strength.

Reduced setup time and assured compatibility with ISO holders

Constructed to ISO specifications, the insert mates with holders that match form, relief angle, tolerance class, clamping method, size and thickness. The 80° rhombic geometry and 0° relief angle are standard references when selecting a matching external holder or boring bar, while the 6.35 mm thickness and cylindrical hole determine the correct clamping accessories. Specifying these dimensional parameters before procurement minimises downtime during tool changes and ensures immediate fitment, so production lines stay on schedule and tool inventories remain consistent.

Consistent chip control and secure edge performance

A double‑sided chipbreaker combined with a 1.2 mm corner radius provides controlled chip formation and improved edge strength for medium to heavy passes. The cylindrical hole allows positive clamping and straightforward indexing, effectively doubling available cutting edges without complex setup. These features translate into safer machining of interrupted cuts and improved surface quality in demanding operations. For system integrity, use with the correct underlay, clamp set and replacement screws as part of the ISO insert system to benefit from repeatable clamping torque and stable cutting conditions.

FAQ

What materials is this insert suitable for?
The CNMG190612 T9225 insert is specified as a robust universal grade for steel machining and performs well in medium to heavy cutting of alloyed and non‑alloyed steels.

How does the T9225 grade affect tool life?
The T9225 CVD coating increases wear resistance and edge stability, so the insert maintains a usable cutting edge longer under varying engagement conditions compared with uncoated grades.

Can the insert be indexed to use multiple cutting edges?
Yes, the rhombic CNMG format is double‑sided and designed for indexing; the cylindrical hole ensures secure clamping and straightforward re‑indexing.

Which holders are compatible with this ISO insert?
Compatibility depends on matching the ISO geometry: form, relief angle 0°, tolerance class, clamping style, size (19 mm) and thickness (6.35 mm). Use holders specified for CNMG 190612 inserts for correct fit.

What operational benefits does the 1.2 mm corner radius provide?
A 1.2 mm corner radius increases edge strength and reduces the likelihood of chipping during interrupted cuts, improving surface finish and extending usable edge life.
