SNMG120412 T9235 Tungaloy turning insert — 90° ISO indexable insert for turning

SNMG120412 T9235 is an ISO‑format indexable turning insert designed for external and internal turning applications where interrupted cuts or unstable conditions demand a robust grade and repeatable clamping.

• CVD-coated carbide grade T9235
• ISO SNMG120412 square insert, 90° geometry
• 1.2 mm corner radius for robust edge
• Double-sided chipbreaker, reversible use

Consistent edge life for interrupted turning

The CVD-coated carbide composition of the grade T9235 provides a combination of toughness and wear resistance specifically intended for steel machining at moderate cutting speeds. In practice this means improved resistance to chipping during interrupted cuts and reduced flank wear under less stable setups. The coating process yields a hard, heat-resistant surface that helps maintain the cutting edge, so component tolerances remain consistent over longer tool life. This results in fewer indexings and lower cumulative downtime on production runs.

Geometry and dimensions that enhance process stability

Built to the ISO SNMG120412 standard, the square shape with 90° geometry offers a positive balance between versatility and rigidity. The 1.2 mm corner radius forms a robust edge that absorbs shock at entry points, while the 4.76 mm thickness and square form ensure secure clamping in compatible holders. The presence of a cylindrical hole supports standard screw clamping systems, promoting repeatable positioning and concentricity. Together these factors reduce vibration and contribute to uniform surface finish and dimensional accuracy during turning.

System guidance and selection for productive machining

Compatibility with toolholders is determined by form, clearance angle, tolerance class, clamping method, size and thickness; select a holder matched to the insert’s profile to exploit the double-sided chipbreaker and reversible use. The chipbreaker style suits a wide range of steel turning operations and helps control chip flow in both external and internal cuts. For unstable set-ups or interrupted machining choose the T9235 grade and a rigid clamping arrangement to maximise productivity. Practical benefits include longer edge life, lower tooling costs per part and fewer tool changes, improving overall process efficiency.

FAQ

Which materials are suitable for this insert?
The SNMG120412 T9235 insert is formulated for machining steel and performs well in operations involving interrupted cutting and less stable set-ups.

How does the T9235 grade differ from general-purpose grades?
Tungaloy’s T9235 is a tougher, CVD‑coated carbide grade aimed at improved resistance to chipping at moderate speeds, offering longer edge life in interrupted cuts compared with more wear‑focused grades.

Is this insert reversible and how many cutting edges are available?
Yes, the SNMG120412 insert features a double‑sided chipbreaker; the design provides multiple usable cutting edges before indexing is required.

What holder characteristics are important for best results?
A holder matched to ISO SNMG geometry with secure screw clamping and minimal overhang is recommended to exploit the insert’s 90° geometry and 1.2 mm corner radius for stable cutting.

What is the manufacturer SKU and article number for ordering?
The manufacturer SKU is TUN6785837 and the article number is 6785837 for the SNMG120412 T9235 indexable insert.
