SNMG 120416 T9235 — ISO indexable turning insert for turning by Tungaloy

The SNMG120416 T9235 is an ISO‑standard indexable turning insert designed for external and internal turning, offering a 90° square form, a 1.6 mm corner radius and a central cylindrical hole for secure clamping.

• ISO SNMG 120416 form, 90° square insert
• CVD-coated T9235 carbide grade
• Double-sided chipbreaker for stable cuts
• Central cylindrical hole, 4.76 mm plate thickness

Consistent cutting under unstable conditions thanks to a tough CVD grade

The CVD‑coated T9235 composition provides a tough cemented carbide substrate optimised for machining steel at moderate cutting speeds and where interrupted cuts or less rigid set‑ups occur. This coating strategy improves edge resistance to chipping and abrasion, which translates into prolonged tool life and fewer unplanned tool changes. The result is more predictable cycle times and improved process reliability for batch and jobbing turning work.

ISO compatibility reduces setup time and tooling complexity

Built to the ISO SNMG 120416 geometry, the insert matches a wide range of indexable turning toolholders when form, clearance angle, tolerance class, fastening method, size and thickness are aligned. The 0° clearance angle and the central cylindrical hole support stable clamping, while the square 90° shape offers multiple usable edges. These features minimise downtime during insert changes and simplify inventory management for workshops handling a variety of turning tasks.

Economical double‑sided geometry lowers cost per edge

The double‑sided chipbreaker and square form provide reversible cutting edges, effectively doubling the number of usable edges per insert. Combined with a 1.6 mm corner radius and 4.76 mm plate thickness, the geometry gives sufficient rigidity for conventional turning while controlling cutting forces and chip formation. This balance of robustness and economy helps reduce tooling costs and improves component repeatability without sacrificing surface integrity.

Practical guidance for turning applications and system setup

Designed for external and internal turning, the insert is intended to be used as part of a system comprising the ISO indexable insert, an appropriate external holder or boring bar, a seating/lock set and replacement screws. Select a chipbreaker and grade aligned with the workpiece material and machining stability: the tough T9235 grade suits unstable set‑ups and interrupted cuts in steel. For quieter, high‑speed applications choose grades and geometries optimised for those conditions. Proper holder compatibility and clamping torque are essential for achieving the described performance and repeatability.

FAQ

What materials is this insert suitable for?
The SNMG120416 T9235 insert is intended primarily for machining steel; the T9235 CVD coating and carbide substrate are formulated to perform well under interrupted cuts and less stable conditions.

How does the CVD coating benefit operation?
A CVD‑coated cemented carbide insert offers improved abrasion resistance and edge stability, which for the SNMG120416 T9235 means longer life in demanding turning operations and fewer tool changes.

Is the insert reversible and how many edges are usable?
The square SNMG geometry with a double‑sided chipbreaker provides reversible edges; each insert offers multiple usable cutting edges when indexed correctly.

What determines compatibility with toolholders?
Compatibility depends on the ISO form, clearance angle, tolerance class, fastening method, size and thickness; the SNMG120416 designation simplifies matching to ISO‑compatible external holders and boring bars.

Which system components are typically needed with this insert?
A complete system comprises the ISO indexable insert, a suitable external holder or bore bar, a seating/lock set and replacement fixing screws to ensure secure clamping and repeatable performance.
