SNMG120408 T9235 SNMG turning insert by Tungaloy — CVD-coated carbide, 90° square

SNMG120408 T9235 is an ISO-format, square indexable insert intended for external and internal turning, engineered for interrupted cuts and unstable cutting conditions.

• CVD-coated carbide T9235 grade
• 0° clearance for stable engagement
• Double-sided insert with cylindrical hole
• 90° square geometry with 0.8 mm corner radius

Reliable chip control for interrupted turning

The SNMG120408 T9235 indexable insert delivers consistent chip formation even in interrupted machining thanks to its double-sided chipbreaker and robust geometry. The combination of a 90° square shape and a 0.8 mm corner radius stabilises engagement during tough cuts, reducing vibration and the risk of tool pull-out. For shops facing frequent non‑continuous cuts, this means fewer re‑setups and more predictable process windows, supporting higher overall productivity on lathes and turning centres.

Longer edge life under unstable conditions

The T9235 designation denotes a CVD-coated carbide grade chosen for toughness rather than maximum speed, which helps maintain edge integrity under lower cutting speeds and variable stability. The CVD coating provides wear resistance at the coating/substrate interface and improves heat management at the cutting edge, so the insert sustains usable life in conditions where a harder, more brittle grade would chip. This balance of toughness and protection translates into a favourable cost‑per‑part ratio for medium‑duty steel turning.

ISO compatibility and straightforward tool changeover

Built to the ISO standard, the insert suits common external holders and boring bars; compatibility depends on form, free angle, tolerance class, fastening, size and thickness. The insert’s cylindrical hole and standard dimensions (12 mm square, 4.76 mm thickness) enable rapid indexing and secure clamping with typical clamp sets and replacement screws. The standardised format simplifies tool inventory and reduces changeover time, helping maintain machining continuity across different workpieces and fixtures.

FAQ

What materials is this insert designed for?
The SNMG120408 T9235 insert is optimised for machining steel, with the T9235 grade selected for toughness in lower‑speed and unstable cutting conditions.

Is the insert indexable and reversible?
Yes — the insert is double‑sided and indexable; the square form permits multiple orientations, and the cylindrical hole supports secure clamping.

Which holders are compatible with this ISO insert?
Compatibility depends on matching the insert form, free angle, tolerance class, fastening method, size and thickness to the holder; the SNMG120408 follows ISO norms for straightforward pairing with standard turning holders and boring bars.

How does the CVD coating affect performance?
The CVD coating increases wear resistance and thermal stability at the cutting edge, helping to prolong tool life under interrupted or demanding cut conditions when using the SNMG120408 T9235 insert.

Can this insert be used for internal turning as well as external turning?
Yes — the ISO-format insert is suitable for both external and internal turning; selection of the correct chipbreaker and grade should reflect workpiece rigidity and the stability of the machining setup.
