CNMG 090308 GT720 indexable turning insert — ISO turning insert for finishing and light turning, Tungaloy

The CNMG 090308 GT720 is an ISO‑standard indexable turning insert engineered for finishing to light turning of steel, offering a fine surface finish and controlled, even wear.

• ISO CNMG 090308 geometry for stability
• Cermet grade GT720 for superior finish
• Double‑sided chipbreaker for flexible indexing
• 0° relief angle for finishing operations

Precision finishing and consistent surface quality

The GT720 grade is a cermet cutting material optimised for finishing and light turning of steel; it delivers a refined surface finish and improved dimensional accuracy compared with standard grades. The material formulation promotes uniform wear across the cutting edge, which reduces variation between indexed positions and extends productive cutting life. For process planners this translates into fewer part reworks and longer intervals between insert replacements, supporting a more predictable production flow and lower unit costs.

Secure clamping and clear holder compatibility

The rhombic CNMG geometry with a nominal size 09 and an included angle of 80° provides reliable cutting edge stability when paired with a compatible external holder or boring bar. The insert features a 0° relief and a 0.8 mm corner radius, offers a plate thickness of 3.18 mm, and is supplied with a cylindrical hole for secure fastening. Compatibility with a holder is determined by form, relief angle, tolerance class, fastening method, size and thickness; selecting the correct combination ensures repeatable clamping, minimised vibration and consistent part quality in turning applications.

Recommended use and process considerations

Designed for external and internal turning, this grade and geometry suit finishing to light roughing of steel where surface quality and dimensional control are priorities. The double‑sided chipbreaker enables two usable cutting edges per index, improving cost efficiency, while the rhombic form allows straightforward indexing and edge rotation. For best results, pair the insert with a stable holder and an appropriate underlay or clamp set; confirm that the chosen chipformer and grade match the workpiece material and process stability to maintain tool life and surface integrity.

FAQ

What machining tasks is this insert best suited for?
The CNMG 090308 GT720 indexable turning insert is best suited for finishing and light turning of steel, offering a combination of surface quality and dimensional control.

How does the GT720 grade improve surface finish?
GT720 is a cermet grade formulated to promote even wear and a fine cutting edge, which helps to produce a consistent, high‑quality surface finish during finishing operations with the CNMG geometry.

Can the insert be used on internal turning operations?
Yes, the geometry and form are suitable for both external and internal turning, provided the correct holder and clamping arrangement are used to ensure stability.

How many cutting edges are available per insert?
The insert features a double‑sided chipbreaker, which provides two usable cutting edges per index and supports economical edge rotation.

What should be checked for holder compatibility?
Compatibility is determined by form, relief angle, tolerance class, fastening type, size and thickness; confirm these parameters against the holder specifications before fitting the insert.
