SNGA 120404 GT720 SNGA — Tungaloy turning insert, cermet grade for finishing

SNGA120404 GT720 Tungaloy is an ISO‑normed square turning insert designed for finishing and light turning of steel components.

• ISO‑standard square insert
• GT720 cermet for fine finishing
• 0.4 mm corner radius for fine profiles
• 0° clearance angle, 90° cutting orientation

Improved surface quality with a cermet finishing grade

The GT720 cermet composition is developed for the finishing to light machining stages where surface finish and dimensional accuracy matter most. As a cermet‑based substrate, the grade reduces built‑up edge formation and promotes uniform wear, which supports repeatable part tolerance and reduces the need for rework. The combination of hard phases and a wear‑resistant matrix gives greater resilience on interrupted cuts and gentle feeds, translating into fewer scrap parts and a more reliable production output.

ISO geometry that simplifies holder selection and setup

Designed as an ISO‑standard square insert (SNGA120404), the component matches common seat forms and clamping systems when the holder's form, clearance angle, tolerance class, fastening and size correspond. The insert’s 12 mm size and 4.76 mm thickness, together with the cylindrical mounting hole, ensure straightforward mounting in most standard outside holders and boring bars. The 0° clearance angle and 90° cutting orientation provide stable shoulder control and make the geometry suitable for versatile external and internal turning operations where rigidity and repeatability are required.

Application guidance for reliable, productive turning

The insert is intended primarily for turning steel in finishing operations; selecting the appropriate chipbreaker and the GT720 sort according to workpiece stability and machining strategy is essential. With a 0.4 mm corner radius, the insert delivers fine profile definition while still allowing modest feed rates. As part of a complete system—indexable insert, matched holder, underlay/clamp set and spare screws—the component contributes to shorter setup times and predictable tool life, supporting cost‑effective batch production and consistent surface quality.

FAQ

What materials is this insert best suited for?
The SNGA120404 GT720 insert is optimised for steel finishing operations; the GT720 cermet grade focusses on surface quality and dimensional stability.

Can the insert be used for internal and external turning?
Yes, the geometry and mounting hole allow the indexable insert to be employed in both external holders and suitable boring bars for internal turning.

How does the 0.4 mm corner radius affect the process?
A 0.4 mm corner radius provides fine profile definition and supports improved surface finish while permitting controlled feeds for finishing passes.

Does the SNGA120404 require a specific holder type?
Compatibility depends on holder form, clearance angle, tolerance class, fastening, size and thickness; confirm with the holder specification to ensure correct seating and clamping.

What advantage does the GT720 grade provide over conventional carbide?
The GT720 cermet grade delivers superior surface finish and more uniform wear in finishing applications, reducing rework and enhancing repeatable dimensional control.
