CNMG 190612 T5105 — ISO rhombic turning insert by Tungaloy for turning

The CNMG190612 T5105 is an ISO‑standard rhombic insert designed for high‑speed machining of cast iron under stable cutting conditions

• CVD‑coated carbide T5105 for wear resistance
• Optimised for high‑speed cast iron turning
• CNMG rhombic 80° geometry for stable cutting
• Double‑sided chipbreaker with cylindrical hole

High‑speed cast iron performance for consistent productivity

The CVD‑coated T5105 grade provides a balanced combination of wear resistance and thermal stability, specifically developed for productive machining of cast iron. The coating reduces flank wear during elevated cutting speeds, which translates into longer tool life and fewer insert changes. For operations where cycle time and repeatability matter, this insert supports steady cutting conditions and reliable surface quality with limited process interruption.

Simple system integration and predictable holder compatibility

The insert follows ISO dimensions and its compatibility with a toolholder depends on form, clearance angle, tolerance class, fastening method, size and thickness. The rhombic CNMG shape with an 80° included edge angle and a 0° clearance angle is suitable for a wide range of standard external and internal turning holders. When selecting a holder, match the insert seat to the geometry and thickness 6.35 mm to ensure correct seating and clamping; this reduces vibration and improves repeatable performance.

Cutting stability and chip control for safer machining

Equipped with a double‑sided chipbreaker and a cylindrical hole for secure fastening, the insert offers stable chip formation during medium to high material removal rates. The corner radius 1.2 mm supports robust cutting edges that withstand intermittent cuts and slight interruptions in feed, improving edge strength and reducing the risk of chipping. Controlled chip formation also helps maintain machine uptime and contributes to a safer shopfloor environment.

Durable carbide substrate and application focus

Manufactured from sintered carbide, the grade delivers a combination of toughness and hardness that is appropriate for machining cast iron in stable setups. The insert is double‑sided, allowing indexation for extended service life before disposal. For best results, pair the grade with compatible holders and set cutting parameters optimised for cast iron to exploit the full potential of the T5105 coating in high‑speed scenarios.

FAQ

What materials is this insert best suited for?
The CNMG190612 T5105 insert is optimised for machining cast iron; the T5105 CVD coating and carbide substrate deliver wear resistance at high cutting speeds for this material group.

How does the corner radius affect cutting?
A 1.2 mm corner radius increases edge strength and promotes stable cutting with improved surface finish when using appropriate feeds; CNMG geometry benefits from this radius in medium to heavy cuts.

Is the insert reversible and how many cutting edges are available?
The insert is double‑sided with indexable edges, permitting rotation to a fresh cutting edge and extending service life before replacement.

Which holder characteristics are essential for correct seating?
Correct holder selection requires matching the ISO form, thickness (6.35 mm), fastening method and tolerance class to ensure secure clamping and vibration‑free operation with this insert.
