CNMG 120404 T5105 Tungaloy turning insert

A CNMG120404 T5105 ISO turning insert designed for high-speed, wear-resistant machining of cast iron under stable conditions.

• CVD-coated carbide T5105 for high-speed turning
• ISO CNMG120404 rhombic 80° geometry
• Double-sided chipbreaker for consistent chip control

Increase throughput with a wear-resistant coating

The CVD-coated T5105 grade provides improved surface hardness and thermal stability, which translates into longer life during demanding cutting operations. For machining cast iron, this coating reduces flank wear and preserves the cutting edge at elevated speeds. By selecting a carbide insert with this specification, process windows can be expanded, enabling higher cutting speeds without sacrificing predictable tool life. The result is fewer interruptions for index changes and a measurable rise in production uptime.

Consistent chip formation for safer machining

A double-sided chipbreaker ensures repeatable chip geometry and reliable evacuation in turning operations, which lowers the risk of chatter and tool damage. The insert’s cylindrical centre hole and standard fixation method contribute to stable clamping in compatible holders, maintaining the position under load. Consistent chips improve surface finish and reduce secondary handling, so cycle times and downstream inspection requirements are reduced while part quality remains stable.

Seamless integration into ISO tool systems

The rhombic ISO CNMG120404 form with an 80° included angle and 0° clearance fits a wide range of standard CNMG holders; compatibility is governed by form, free angle, tolerance class, fixation and thickness. Dimensionally the insert features a 4.76 mm thickness, an inscribed circle of 12 mm and a 0.4 mm nose radius, facilitating precise profiling and repeatable set-up across machines. This conformity allows straightforward replacement and interchangeability in established tooling systems without custom adaptors.

Practical efficiency for workshop operations

The insert’s geometry and material combination target stable turning conditions where predictable performance is critical. The indexable insert concept, combined with a robust carbide substrate, reduces inventory complexity by offering standardised parts that can be rotated or replaced with minimal downtime. For operations aiming to balance cycle speed and surface integrity, this solution contributes to lower tooling costs per component and a more consistent production output.

FAQ

What materials is this insert best suited for?
The CNMG120404 T5105 insert is optimised for cast iron machining, where the CVD-coated T5105 grade provides wear resistance for high-speed turning.

How does the chipbreaker influence machining?
The double-sided chipbreaker on this indexable insert promotes repeatable chip shapes, improving evacuation and surface finish while reducing the likelihood of chip-related interruptions.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, free angle, tolerance class, fixation and insert thickness; the CNMG120404 geometry fits standard CNMG holders designed for 80° rhombic inserts.

How many usable cutting edges are available?
The double-sided design extends service life through indexing; the exact number of edges accessible depends on the specific CNMG variant and indexing procedure used.

What are the key dimensional data for set-up?
Important set-up dimensions include a 0.4 mm nose radius, 4.76 mm thickness, 12 mm inscribed circle, 80° included angle and 0° clearance angle, which helps ensure correct seating and orientation.
