SNMM 250924 T9235 Tungaloy turning insert — CVD-coated carbide, 2.4 mm radius

A SNMM250924 T9235 indexable turning insert designed for external and internal turning where interrupted cuts and unstable conditions demand a tough grade and stable edge performance.

• CVD-coated carbide grade T9235
• 2.4 mm corner radius for edge strength
• Square insert, 90° for robust turning
• One-sided chipbreaker for controlled chips

Durable cutting performance in unstable turning

The CVD-coated carbide grade T9235 is formulated as a tough compound specifically for machining steel at lower cutting speeds and under unstable or interrupted conditions. Because the grade is designed for toughness rather than maximum hardness, the result is improved resistance to chipping and fewer unplanned tool changes when encountering variable chip loads. This focus on durability supports a lower total cost of ownership through longer insert life and fewer stoppages, making it well suited for roughing operations or where component geometry causes intermittent engagement.

Reliable geometry for process stability and surface quality

The 2.4 mm corner radius and square 90° shape concentrate edge strength where it is most needed, reducing localised stress and preserving dimensional stability during aggressive cuts. The one-sided chipbreaker helps to control swarf formation and directs chips away from the cutting zone, which enhances surface finish and reduces the likelihood of recutting. Together, these geometric features aid in maintaining consistent results across workpieces and shifts, delivering reproducible quality for series production and small-batch turning alike.

Simple integration into ISO tool systems

Compatibility is determined by form, relief angle (0°), tolerance class, fastening method, size (25 mm) and thickness (9.52 mm). The insert has a cylindrical hole for positive clamping and is intended to be used with the appropriate external holder or boring bar, plus a matching shim/clamping set and replacement screws. Specifying the correct holder geometry and clamping hardware ensures the insert sits true and transmits cutting forces effectively, reducing vibration and maximising tool life.

Application-oriented choice for steel machining

This insert is optimised for turning steel in applications where interrupted cuts, lower cutting speeds or less rigid set-ups are present. Selecting the SNMM250924 with the T9235 grade provides a pragmatic balance between wear resistance and edge toughness — beneficial when stability cannot be guaranteed or when tool life must be prioritised over maximum metal removal rate. For finishing passes on stable setups, consider swapping to a finer, wear-optimised grade; for the roughing stage, this insert maintains integrity under shock loads.

Practical benefits and workshop workflow

Using ISO-standard indexable inserts such as this one simplifies inventory and reduces changeover complexity: identical geometry inserts can be rotated to renew cutting edges, and the insert family works with commonly available holders. The systemic approach — insert + holder + shim/clamping set + spare screws — reduces downtime and supports consistent setups across machines. For unfamiliar workpieces or borderline conditions, trial cuts with conservative feeds and speeds will quickly validate the insert’s performance without risking part quality.

FAQ

What materials is this insert suitable for?
The SNMM250924 T9235 indexable insert is optimised for machining steel; the T9235 CVD-coated carbide grade favours toughness for interrupted and unstable cutting conditions.

How does the 2.4 mm corner radius affect machining?
A 2.4 mm corner radius increases edge strength and reduces the risk of chipping under shock loads; the geometry of this insert supports robust turning and contributes to stable dimensional results.

Which holder and clamping parts are required for correct use?
The insert must be mounted in a compatible ISO external holder or boring bar with the correct shim/clamping set and replacement screws; compatibility depends on form, relief angle (0°), size and thickness.

Can this insert be used for internal turning?
Yes, the SNMM250924 Tungaloy turning insert is suitable for both external and internal turning provided a properly matched boring bar or holder is used.

What is the function of the one-sided chipbreaker?
The one-sided chipbreaker controls chip shape and evacuation on the active cutting edge, improving surface finish and reducing the likelihood of recutting and chip interference during turning.
