SNMG 120412 T9215 — ISO turning insert, Tungaloy

The SNMG 120412 T9215 is an ISO-format square turning insert intended for external and internal turning of medium-strength steels, combining a robust cutting grade with a double-sided chipbreaker for steady production runs.

• ISO-format SNMG insert, square form
• CVD-coated carbide grade T9215 for durability
• 90° lead angle, 1.2 mm corner radius
• Double-sided chipbreaker, with cylindrical hole

Productivity and wear resistance for efficient steel turning

The insert uses a CVD-coated carbide substrate in grade T9215, engineered to balance wear resistance with fracture toughness. This combination translates into longer tool life and fewer interruptions for insert changes, which raises machine utilisation and reduces per-part tooling cost. The coating promotes stable performance during continuous and slightly interrupted cuts, while the carbide core maintains edge strength under load. Acceptable for a broad range of medium steels, the geometry supports repeatable part quality and predictable tool-change intervals.

Straightforward integration with existing holders and secure clamping

Compatibility with the toolholder is determined by the insert form, clearance angle, tolerance class, clamping style, size and thickness. The ISO designation simplifies selection for standard SNMG external holders and boring bars; the insert’s cylindrical hole enables reliable axial location and secure fastening. A 0° clearance angle and standard thickness facilitate interchangeability in production tooling systems, reducing setup time. Where holder tolerance or clamping components vary, consulting the component specifications ensures optimal seat contact and repeatable seating.

Consistent chip control and reliable performance during production

The double-sided chipbreaker is designed for controlled chip formation in turning operations, supporting a clean evacuation in continuous cuts and dampening tendencies for built-up edge under moderate feeds. The square plate geometry with 90° lead angle and 1.2 mm corner radius delivers robust cutting edges for facing and turning passes, while the 4.76 mm plate thickness and 12 mm plate size provide dimensional stability at the cutting zone. For production environments requiring predictable surface finish and steady metal removal rates, this indexable insert combines robustness with practical chip control.

FAQ

What materials is this insert suitable for machining?
The SNMG 120412 T9215 insert is optimised for medium steels; the T9215 CVD-coated carbide combines wear resistance and toughness for a wide range of steel grades.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, clearance angle, tolerance class, clamping and the insert thickness; use holders designed for SNMG-format inserts and verify seat geometry before production.

What is the purpose of the cylindrical hole in the insert?
The cylindrical hole ensures positive axial location and secure clamping in the toolholder, improving repeatability during index changes.

How does the chipbreaker design affect process stability?
The double-sided chipbreaker promotes controlled chip formation in continuous cuts, improving evacuation and surface finish while reducing the risk of built-up edge.

Can this insert be used for interrupted cuts?
Yes; the grade T9215 and the robust carbide substrate provide fracture resistance suitable for continuous to slightly interrupted cutting conditions.
