SNMG 120412 AH6235 ISO turning insert for turning — Tungaloy

The SNMG120412 AH6235 is a square ISO turning insert designed for external and internal turning, optimised for stainless steel and for operations with elevated breakout risk.

• ISO square insert SNMG 12 size
• PVD-coated carbide grade AH6235
• Suitable for stainless steel and interrupted cuts
• Double-sided chipbreaker with cylindrical hole

Reliable edge life and material compatibility for consistent production

The SNMG120412 combines a PVD-coated surface with the AH6235 carbide grade to deliver improved toughness and wear resistance when machining stainless steel. This composition reduces the frequency of insert changes and stabilises process costs by extending edge life under intermittent cutting conditions. The double-sided chipbreaker promotes predictable chip formation, which in turn decreases the risk of built-up edge and unexpected downtime, supporting uninterrupted production cycles.

Geometry and dimensions that support precision and stability

A square plate with a nominal size of 12 mm, a 1.2 mm corner radius and a plate thickness of 4.76 mm provides a balance between strength and cutting versatility. The 90° cutting geometry is particularly suited to shoulder work and facing operations, offering a robust cutting edge for heavy engagement. The presence of a cylindrical hole enables secure clamping in standard ISO holders, improving repeatability and reducing orientation errors during indexation.

System approach and practical selection guidance for secure machining

Delivered as part of an ISO insert system, the cutting plate is intended to be used in conjunction with a suitable external holder or boring bar, plus the required shim/clamp set and replacement screws. Compatibility with a holder is determined by form, clearance angle, tolerance class, attachment and thickness, so matching the insert geometry to the toolholder and workpiece dynamics is crucial. For applications with high breakout risk or interrupted cuts, the chosen grade and chipformer combination optimises process reliability without compromising surface quality.

FAQ

What materials is this insert designed for?
The SNMG120412 AH6235 insert is optimised for machining stainless steel and performs well in interrupted cutting scenarios where a tougher grade is required.

Can the insert be indexed during production?
Yes, the insert is double-sided and allows indexing; the SNMG120412 design supports straightforward rotation to a fresh cutting edge.

What advantages does the AH6235 grade offer?
AH6235 is a PVD-coated carbide grade engineered for higher toughness and improved resistance to edge chipping when turning stainless steel and under interrupted cuts.

How is the insert secured to the toolholder?
The insert features a cylindrical hole for secure fastening and is compatible with ISO-standard holders; clamping depends on form, clearance angle, tolerance class, attachment, size and thickness.

Is the SNMG120412 suitable for facing and shoulder cuts?
Yes, the 90° geometry and 1.2 mm corner radius make this insert well suited to facing and shoulder operations where a robust edge is required.
