CNMM 120408 T9235 — Indexable turning insert (turning) by Tungaloy

CNMM120408 T9235 is an ISO‑standard indexable insert for general turning applications, engineered for reliable performance in interrupted cuts and lower cutting speeds

• ISO‑standard CNMM geometry, rhombic form
• CVD‑coated carbide T9235 for steel
• 0.8 mm corner radius for sturdy edges
• Cylindrical hole for secure mounting

Consistent performance in unstable cutting conditions

The insert is manufactured in the T9235 grade, a CVD‑coated carbide formulation designed to tolerate lower speeds and interrupted cuts while maintaining edge integrity. The tougher substrate and coating combination reduces chipping risk under unstable conditions, which results in fewer unexpected tool changes and more predictable production cycles. For shops facing variable workpiece clamping or intermittent cut patterns, this specification offers a robust compromise between wear resistance and fracture toughness, helping to sustain machining continuity and reduce scrap rates.

Secure seating and ISO compatibility for easy integration

Built to the ISO specification, the rhombic geometry and cylindrical hole ensure positive locating and repeatable clamping in compatible holders. Compatibility with a toolholder depends on parameters such as form, relief angle, tolerance class, fastening and thickness; the standardised dimensions ease tool management across different machines. The 0° relief angle is suitable for neutral cutting actions where chip flow and support must be balanced. Clear identification of the insert geometry simplifies inventory control and reduces setup time when replacing inserts in multi‑operator environments.

Balanced edge strength for versatile turning tasks

A 0.8 mm corner radius delivers reinforced cutting edges that tolerate heavier engagement and intermittent contact, while the 4.76 mm plate thickness contributes to overall stiffness and heat absorption at the tool tip. The single‑sided chipbreaker supports consistent chip formation when machining steel varieties, enabling safer chip evacuation and reduced recutting of chips. This geometry is particularly beneficial for mixed production runs where both external and internal turning operations are required without frequent tool changes.

System considerations and practical guidance

The complete system comprises the ISO turning insert, the appropriate external holder or boring bar, a locating shim or clamp set, and replacement screws. Select a chipbreaker and grade combination that matches the workpiece material, machining type and fixture stability to fully exploit the insert’s capabilities. Routine inspection of the clamping torque and seating surface will preserve repeatability and prevent premature tool failure. When in doubt about holder fit or process parameters, technical consultation is advisable to align cutting data with shop conditions and to extend tool life.

FAQ

What workpieces is this insert best suited for?
The CNMM120408 T9235 insert is optimised for machining steel where interrupted cuts or less stable setups occur; the T9235 grade balances toughness and wear resistance for such conditions.

How does the T9235 grade differ from standard grades?
T9235 is a CVD‑coated carbide grade selected for increased fracture resistance at the expense of slightly lower cutting speed capability, making it advantageous for interrupted or unstable turning operations.

Can this insert be used for finishing passes?
Yes, with appropriate cutting data and a stable holder the insert provides acceptable surface quality; however, for high‑speed finishing a finer grade may yield better surface finish.

Which holder features are required for secure mounting?
Secure mounting depends on matching form, free angle, tolerance class, fastening and insert thickness; the rhombic form and cylindrical hole demand a compatible ISO‑type holder with correct shim and clamping set.

Is the insert reversible or single‑sided?
This is a single‑sided insert with a single effective cutting edge and a single‑sided chipbreaker; its geometry is intended for robust edge strength rather than multiple indexings.
