SNMG 090308 T9235 Wendeplatten - Tungaloy

Benefit from the combination of a CVD-coated carbide substrate and the tough T9235 grade, which together provide reliable wear resistance and stability in interrupted cuts; the 0.8 mm corner radius supports consistent finishing. The ISO SNMG090308 format ensures compatibility with standard clamping systems. Order the SNMG090308-TM T9235 indexable turning insert directly via Metav Werkzeuge or ask our consultants if needed.

SNMG 090308 T9235 – ISO SNMG indexable turning insert for turning, CVD-coated carbide, 0.8 mm radius (Tungaloy)

The SNMG090308-TM T9235 is an ISO-standard indexable insert intended for external and internal turning, combining a square form with a cylindrical-hole fixing and a robust TM chipbreaker for interrupted or unstable cutting conditions.

• CVD-coated carbide for improved wear resistance
• Tough grade T9235 for unstable cutting conditions
• ISO SNMG090308 format with 0.8 mm corner radius
• Cylindrical hole fixing for secure clamping

Proven performance under interrupted and unstable cutting

The insert is manufactured from CVD-coated carbide, offering a balance between wear resistance and toughness that suits demanding turning tasks. The T9235 grade is formulated for lower cutting speeds and applications where chip control and edge stability are more critical than maximum cutting speed. This makes the insert particularly effective when machining steels under unstable conditions or where intermittent cuts are expected; the outcome is reduced flank wear and longer tool life, which helps to maintain production continuity and lower overall tooling costs.

Built to fit standard systems for quick changeovers

Designed in the ISO SNMG090308 format with a square outline, the insert fits a wide range of holders and boring bars. Compatibility is defined by shape, relief angle, tolerance class, fastening method, size and thickness, so the standardised geometry simplifies replacement and inventory management. The cylindrical-hole fixing ensures reliable seating and repeatable positioning, enabling rapid index changes and minimising machine downtime — a rational advantage for busy shop floors seeking predictable cycle times.

Better surface quality and controlled chip formation

A 0.8 mm corner radius provides a compromise between strength and edge sharpness: it reduces the risk of edge chipping while still supporting acceptable surface finish for turned components. The TM chipbreaker is optimised for the grade and common steel applications, promoting short, manageable chips and consistent contact between the insert and workpiece. For operators unfamiliar with chipbreaker behaviour, the result is easier chip evacuation and fewer process interruptions, which contributes directly to improved component quality and reduced rework.

Application guidance for reliable results

The insert is intended primarily for turning of steel and is especially suitable where stability is limited or cuts are intermittently interrupted. For best results, pair the insert with a suitable external or internal holder, an appropriate shim or clamping set, and the correct tightening torque for the replacement screws. The system approach — insert, holder, shim/clamping set and spare screws — ensures repeatable clamping and consistent performance across batches. For customers evaluating process windows, the combination of a tough grade and CVD coating offers a pragmatic balance between tool life and machining stability.

FAQ

What materials is this insert suitable for?
The SNMG090308-TM T9235 insert is engineered primarily for machining steel; the T9235 grade provides toughness for interrupted cuts and unstable conditions when turning steel components.

What does the grade T9235 indicate?
T9235 denotes a tough, CVD-coated carbide grade designed to withstand interrupted cuts and variable stability while maintaining wear resistance on steel workpieces.

How does the SNMG090308 designation translate to geometry?
SNMG identifies a square insert with negative geometry; the code 090308 corresponds to size, thickness and other ISO geometry details, here matching a 0.8 mm corner radius and 3.18 mm thickness.

How is the insert secured in the holder?
The insert uses a cylindrical-hole fixing in combination with a clamping system; secure seating depends on matching shape, relief angle, tolerance class, fastening method, size and thickness.
