CNMG160612 T5105 turning insert by Tungaloy — ISO rhombic geometry, CVD-coated carbide

CNMG160612 T5105 is an ISO rhombic turning insert developed for high-speed external and internal turning of cast iron under stable machining conditions.

• ISO rhombic CNMG 160612 geometry
• CVD-coated carbide for high-speed cutting
• Double-sided chipbreaker for stable swarf
• Cylindrical-hole design for secure clamping

Consistent high-speed performance for cast iron

The CVD-coated carbide grade T5105 offers a balance of wear resistance and toughness tailored to high-speed machining of cast iron. The coating reduces flank wear and extends usable life during uninterrupted cuts, which translates into fewer insert changes and steadier cycle times. For production or job-shop environments that prioritise throughput, this grade maintains edge integrity while preserving workpiece quality.

Reliable clamping and dimensional stability

With a cylindrical hole and ISO CNMG form, this insert ensures precise seating and reproducible positioning in compatible holders. The 80° lead angle and 0° clearance geometry deliver predictable cutting forces, while the 1.2 mm corner radius smooths transitions to improve edge strength and reduce the risk of chipping. Clear compatibility depends on holder form, tolerance class, attachment type, size and thickness.

Efficient chip control for safer, cleaner machining

Equipped with a double-sided chipbreaker, the indexable cutting element breaks and guides swarf reliably in stable cutting conditions. This feature helps to avoid long, stringy chips and supports consistent surface finish on cast iron components. Explaining briefly: a chipbreaker modifies the way the cut material curls and fractures, improving evacuation and reducing re-cutting, which benefits both machine uptime and operator safety.

Easy selection and integration into turning systems

As an ISO-standardised insert, the component integrates with a wide range of external holders and boring bars when the matching specifications are observed. The 6.35 mm thickness and 16 mm size are common in turning tool systems, simplifying stocking and supplier logistics. Technical integration advice is available to confirm holder compatibility and optimal cutting parameters for a given machine setup.

FAQ

What materials is this insert designed for?
The T5105 grade is formulated for high-speed machining of cast iron; the CNMG160612 insert performs best under stable cutting conditions with appropriate holders.

Can the insert be used on internal turning operations?
Yes, the ISO CNMG form and cylindrical-hole configuration allow use in both external and internal turning setups when a compatible boring bar or holder is employed.

How does the chipbreaker affect surface finish?
The double-sided chipbreaker promotes controlled chip formation and evacuation, which supports a consistent surface finish on cast iron workpieces and reduces interruption from chip entanglement.

Is the insert reversible or single-use per edge?
The CNMG geometry is double-sided; each side provides a usable cutting edge, offering multiple indexing positions before replacement.

Which parameters determine holder compatibility?
Holder compatibility is governed by the insert form, clearance angle, tolerance class, attachment method, size and thickness; confirm these matches with the chosen toolholder.
