SNMG 120408 GH330 — Tungaloy SNMG indexable insert for turning, 12 mm, 0° relief

SNMG120408 GH330 is an ISO-standard square indexable insert designed for external and internal turning where wear resistance and cutting-edge stability are essential

• ISO-standard square insert SNMG 12 mm
• GH330 grade for wear resistance and toughness
• Double-sided chipbreaker for longer use
• 0° relief angle, 0.8 mm corner radius

Consistent component life through tailored grade and geometry

The SNMG120408 GH330 indexable insert pairs a purpose-designed geometry with the GH330 carbide formulation to deliver a balance of wear resistance and toughness. The square format with a measured 12 mm side and 0.8 mm corner radius provides predictable contact conditions and supports consistent surface quality during turning. The ISO standardisation guarantees repeatable fitment in compatible holders and reduces uncertainty when specifying inserts for production runs, supporting stable cycle times and fewer unscheduled tool changes.

Higher productivity via double-sided indexing and robust carbide

A double-sided chipbreaker extends usable cutting edges and reduces tooling costs per component by allowing multiple reindexes. The carbide substrate maintains edge integrity under intermittent heavy cuts, while the 0° relief reduces flank contact where geometry and machine setup permit. These characteristics translate into measurable efficiency: longer intervals between insert changes and reliable edge behaviour under varying feed and depth conditions — advantages that improve throughput without sacrificing part tolerances.

Clear system compatibility for reliable clamping and set-up

Compatibility with a clamping system is determined by insert shape, relief angle, tolerance class, fastening method, size and thickness. The insert is supplied with a cylindrical hole for positive locating and secure fastening in a range of standard external holders or boring bars. Typical system components include the matching external holder or boring bar, the seat or clamp set and replacement screws. Specifying the ISO designation and geometric data when ordering ensures correct seating and repeatable cutting geometry, which in turn supports predictable tool life and process reliability.

Practical guidance for selection and application

Designed for general turning tasks, the insert performs best when the chipbreaker and GH330 grade are chosen to match the workpiece material, cutting parameters and machine stability. The double-sided chip control helps manage chip flow and cutting forces, while the square outline provides four usable cutting corners per side where applicable. For detailed matching of grade, chipbreaker and cutting data to a particular component or machine, Metav Werkzeuge can provide specification support and further technical details.

FAQ

What machining tasks is this insert designed for?
The SNMG120408 GH330 indexable insert from Tungaloy is designed for external and internal turning applications where a balance of wear resistance and edge stability is required.

How is the insert secured in a holder?
Compatibility depends on form, relief angle, tolerance class, fastening, size and thickness; the SNMG120408 uses a cylindrical hole for location and secure clamping in standard turning holders or boring bars.

What advantages does the GH330 grade provide?
The Tungaloy GH330 grade offers an engineered balance of wear resistance, toughness and cutting-edge stability, resulting in predictable tool life and robust performance under varied turning conditions.

Is the insert indexable and does it reduce tooling costs?
Yes; the double-sided chipbreaker and square geometry permit multiple reindexes, extending usable cutting edges and lowering tooling cost per part.

Which key dimensions should be specified when ordering?
Provide the ISO designation SNMG120408, size (12 mm), thickness (4.76 mm), corner radius (0.8 mm), relief angle (0°) and manufacturer article number 6806769 to ensure correct match and fitment.
