SNMG120408 T9235 indexable turning insert by Tungaloy – for turning

A SNMG120408 T9235 is an ISO-standard indexable insert designed for external and internal turning of steel, offering a tough CVD-coated carbide grade for lower cutting speeds and unstable machining conditions.

• CVD-coated carbide grade T9235
• Designed for unstable cuts and interrupted cuts
• ISO SNMG120408 form, 0.8 mm corner radius
• Double-sided chipbreaker, cylindrical hole

Consistent chip control and toughness for challenging turning tasks

The CVD-coated carbide grade T9235 is engineered to combine toughness with reliable wear resistance, making the insert particularly suitable for turning steel under variable stability and interrupted cutting regimes. The chemical vapour deposited coating enhances substrate protection and reduces adhesion of workpiece material, which helps to maintain a consistent cutting edge. In practice, this means fewer unplanned tool changes and more predictable cycle times, especially when machining components with interrupted profiles or variable fixturing conditions.

Secure fit and ISO compatibility reduce setup uncertainty

As an ISO SNMG120408 insert, the geometry and mounting features are standardised: square form, 0° clearance, and a cylindrical hole for positive clamping engagement. These dimensions determine compatibility with holders through form, clearance angle, tolerance class, fastening and thickness. The 0.8 mm corner radius and plate thickness of 4.76 mm provide a balance between edge strength and accessibility in tight contours. Using the correct holder and shim/clamp set ensures repeatable seating and reduces vibration, which in turn stabilises the cutting process and improves surface finish.

Practical operating benefits and recommended application

The double-sided chipbreaker design enables two indexed cutting edges, improving cost efficiency per insert and simplifying stock management. With its square shape and through-hole, the insert is intended for systems comprising an insert, matching outside holder or boring bar, a support shim/clamp set and spare fastening screws. For best results, match the chipbreaker and grade selection to workpiece stability and the intended cutting parameters; the grade is optimised for lower cutting speeds and less rigid setups, where toughness and reliable chip formation are decisive. Where higher speed or finishing is required, selection of a different grade or tool geometry should be considered.

FAQ

What materials is this insert best suited for?
The SNMG120408 T9235 insert is optimised for machining steel; the T9235 grade provides toughness for unstable or interrupted cutting conditions.

How is the insert mounted and secured?
The insert uses a cylindrical hole and is intended for ISO-compatible holders with a matching clamp or shim set; secure clamping is essential for repeatable performance.

Can the insert be indexed for a second cutting edge?
Yes, the insert is double-sided with two usable cutting edges, which extends service life and improves cost efficiency per edge.

What is the corner radius and how does it affect performance?
The corner radius is 0.8 mm, offering improved edge strength for interrupted cuts while maintaining good access for contour turning.

Is this insert suitable for finishing passes?
The T9235 grade is tuned for lower cutting speeds and stability-challenged conditions; for high-speed finishing, a different grade or geometry may be preferable.
