SNMG 120412 T9235 turning insert by Tungaloy

The SNMG120412 T9235 is an ISO-standard turning insert for external and internal turning, engineered for interrupted cuts and unstable machining conditions.

• SNMG ISO geometry for standardised clamping
• CVD-coated carbide grade T9235 for toughness
• 1.2 mm corner radius for durable cutting edges
• Double-sided chipbreaker for repeatable chip control

Reliable cutting performance in unstable turning operations

The insert’s core advantage lies in its CVD-coated carbide grade T9235, a formulation designed for toughness at lower cutting speeds and in interrupted cutting scenarios. This grade reduces the risk of premature edge chipping when machining steel under variable conditions and therefore supports longer tool life and fewer unscheduled tool changes. The result is a more predictable production rhythm and reduced downtime compared with uncoated or less resilient grades.

Consistent surface finish and controlled chip formation

The SNMG geometry combined with a double-sided chipbreaker promotes stable chip formation and repeatable surface quality. The square, 90° insert shape with a 1.2 mm corner radius balances edge strength and achievable detail on profiles, making it suitable where robust engagement and acceptable finish are both required. Explaining briefly: the chipbreaker’s form influences how chips curl and break away, so a matched chipbreaker helps maintain consistent forces on the tool and workpiece during variable or interrupted cuts.

ISO compatibility for simple integration into turning systems

As an ISO-standard turning insert, compatibility with a suitable external holder is defined by form, relief angle, tolerance class, fastening method, size and thickness. The insert’s 4.76 mm thickness, 12 mm size and cylindrical hole with clamping provision fit common ISO holders when the holder is selected to match these dimensions. Choosing the correct holder and clamping set ensures reliable seat, minimised vibration and repeatable geometry from edge to edge, which together improve process security and reproducibility in serial production.

FAQ

Which materials is this insert best suited for?
The SNMG120412 T9235 insert is specified for machining steel, with the T9235 grade engineered for toughness under interrupted or unstable cutting conditions.

What are the key dimensions and angles of the insert?
Dimensions include a 12 mm size, 4.76 mm thickness and a 1.2 mm corner radius; the insert uses a 90° geometry and has a 0° relief angle with a cylindrical hole for clamping.

Is a special holder required for mounting?
The insert fits ISO holders that match the SNMG form, relief angle, tolerance class, fastening method, size and thickness; select a compatible external holder and clamping set for secure seating and repeatable performance.

What coating and substrate are used on this grade?
This grade is a CVD-coated carbide (T9235), combining a wear-resistant coating with a tough carbide substrate to withstand interrupted cuts at moderate speeds.

How is chip control achieved with this insert?
Chip control is supported by the double-sided chipbreaker; pairing the chipbreaker geometry with appropriate cutting data and a matched holder promotes predictable chip formation and surface quality.
