SNMA120404 GT720 ISO turning insert for precision finishing, Tungaloy

The SNMA120404 GT720 is an ISO-pattern, square turning insert designed for finishing and light turning of steel, optimised for reproducible surface quality and dimensional control.

• Cermet grade GT720 for fine finishing
• 0.4 mm nose radius for precise profiles
• Square SNMA form, 90° cutting edge
• Cylindrical hole for secure clamping

High-quality finishing and predictable tool life

The GT720 grade is a cermet formulation developed to balance wear resistance with excellent surface finish. Its composition and coating promote uniform wear, which helps maintain dimensional accuracy over longer series runs. For operations that prioritise part quality and reduced rework, the combination of a fine cutting edge and the 0.4 mm nose radius supports tight radii and controlled chip formation, resulting in fewer downstream operations and stable finish values.

Seamless integration into ISO tooling systems

Designed to ISO conventions, the insert’s compatibility depends on form, relief angle, tolerance class, fastening, size and thickness. The square SNMA geometry with a 90° approach angle simplifies set-up for conventional external and internal turning. The insert sits within a system that typically includes an appropriate holder or boring bar, a support pad or clamp set and replacement screws, so toolroom planning focuses on matching the holder contour and clamping method rather than custom tooling.

Application focus and machining benefits

Intended for finishing to light cutting, this insert performs well in turning steel where surface quality and repeatable dimensional results matter most. The absence of an integrated chipbreaker means selection of cutting data and grade should match workpiece stability and process strategy. When deployed with appropriate feeds and speeds, the grade reduces the need for manual finishing, contributes to cycle-time stability and supports efficient, predictable serial production.

FAQ

What applications is this insert best suited for?
The SNMA120404 GT720 insert is aimed at finishing and light turning of steel where surface quality and dimensional consistency are priorities.

Which holder types are compatible with this insert?
Compatibility follows ISO geometry; the SNMA form fits matching square external holders or boring bars designed for ISO inserts with a cylindrical centre hole.

How does the GT720 grade affect machining performance?
GT720 is a cermet-based grade tuned for good surface finish and uniform wear, supporting consistent part quality across production batches.

Is this insert supplied with a chipbreaker?
This variant is specified without an integrated chipbreaker; chip control should be achieved through grade selection and cutting parameters.
