SNGG 120404 GH110 – ISO turning insert by Tungaloy, square 12 mm, 0° relief

A SNGG120404-01 GH110 Tungaloy insert designed for precision external and internal turning in ISO-compatible holders, offering a balance of wear resistance and edge stability.

• ISO 120404 square insert, 12 mm size
• GH110 Tungaloy grade for wear resistance
• 0° relief angle for stable cutting
• Cylindrical-hole clamping, 0.4 mm corner radius

Reliable ISO fit for consistent machining results

The insert conforms to the ISO 120404 designation and is manufactured in a square format with a 12 mm side length, ensuring straightforward compatibility with standard indexable turning holders. This ISO standardisation simplifies tool set-up and spare-part management in production environments, reducing downtime. The supplied geometry, including the 90° included angle, supports both external and internal turning operations and promotes predictable chip flow when combined with the correct chipbreaker and holder selection.

Grade and substrate delivering extended tool life

Manufactured from cemented carbide and specified in the GH110 Tungaloy grade, the insert is engineered for a blend of wear resistance and edge toughness. This combination helps maintain cutting-edge integrity under varying cutting conditions, extending service intervals and improving process economy. The grade complements the insert geometry so that, in applications prioritising longevity over maximum metal removal rates, operators can expect dependable performance and reduced frequency of index changes.

Geometry and clamping for process stability

The insert features a 0° relief angle and a corner radius of 0.4 mm, which together provide a stable cutting edge for general turning tasks where surface finish and dimensional control matter. Clamping is via a cylindrical hole, designed for secure axial location in compatible holders; this ensures repeatable positioning after index changes. When paired with an appropriate chipbreaker (type 01) and a robust external holder or boring bar, the system promotes vibration damping and consistent results across batches.

Practical selection and application guidance

For efficient use, pair the insert with an ISO-compatible external holder or boring bar that matches the form, clearance angle, tolerance class, fastening method, size and thickness requirements of the insert. Select the chipbreaker and grade based on workpiece material and machining stability: the GH110 grade suits a wide range of turning tasks where a balance of productivity and tool life is required. Simple checks during tool set-up—correct seat, clean clamping surfaces and appropriate torque for the fixing screw—help achieve the expected repeatability and surface quality.

FAQ

What materials is this insert suitable for?
The SNGG120404-01 GH110 Tungaloy insert is designed for general turning; the GH110 grade provides a balance of wear resistance and toughness suitable across a broad range of steels and common engineering materials when paired with the appropriate machining parameters.

How is the insert clamped in the holder?
Clamping is via a cylindrical central hole; the insert locates axially and is secured with a matching screw and clamping set in an ISO-compatible external holder or boring bar.

What does the 0° relief angle mean for cutting performance?
A 0° relief offers a neutral clearance that stabilises the cutting edge for many turning operations, aiding dimensional consistency and surface finish when used with the correct holder rigidity and cutting parameters.

Can this insert be used for internal (boring) operations?
Yes, the square geometry and ISO designation make the insert suitable for both external and internal turning, provided the chosen boring bar or holder matches the insert form, size and clamping style.

How does the GH110 grade influence tool life?
The GH110 Tungaloy grade is formulated to balance wear resistance and edge stability, extending effective cutting life in typical turning applications and helping to reduce tool-change frequency under stable machining conditions.
