Productivity gains from a coated Tiger·tec Gold grade

The use of the Tiger·tec Gold coating technology and the WPP30G grade provides a measurable improvement in tool life and wear resistance when machining steels. Coated carbide grades combine a tough substrate with a multi-layer coating strategy to resist abrasion and adhesive wear; this results in longer intervals between indexings and fewer tool changes in batch production. For machining of unalloyed and alloyed steels (ISO group P), the coated grade moderates the thermal and mechanical stresses at the cutting edge, leading to steadier performance over longer cycles and a more predictable process window.

Reliable chip control and consistent surface results

Thanks to the HU7 chipbreaker geometry and the rhombic 80° shape, this indexable insert supports controlled chip breaking and evacuation under typical steel cutting conditions. The chipbreaker reduces the risk of long, stringy chips and assists in maintaining a stable cutting zone, which helps to protect the workpiece surface and tool edge. The negative 0° rake contributes to a robust cutting geometry that favours interrupted cuts and heavy roughing passes, while the 1.6 mm corner radius increases edge endurance and reduces chipping during demanding operations.

Designed for production environments and process security

The rhombic 80° form and the insert dimensions make this grade suitable for a wide range of turning applications, from roughing to semi-finishing, in serial production. The insert’s tolerance class M supports repeatable seating and predictable geometrical behaviour in tool holders designed for CNMM-style inserts. Combined with the coated grade’s wear properties, the result is improved process security and fewer unplanned stoppages — a direct benefit to throughput and overall productivity in a machining cell.

FAQ

Which materials is this insert suitable for?
The CNMM190616-HU7 WPP30G is designed primarily for ISO P materials, meaning unalloyed and alloyed steels; the WPP30G grade is tuned to handle the heat and chip formation typical of steel turning.

What benefits does the Tiger·tec Gold coating provide?
Tiger·tec Gold coating on the WPP30G grade enhances wear resistance and thermal stability, improving tool life and ensuring more consistent cutting performance across production runs.

How does the HU7 chipbreaker influence machining?
The HU7 chipbreaker promotes reliable chip control for steel turning, reducing long chip formation and aiding evacuation to keep the cutting zone clear and the surface finish consistent.

Is the negative 0° rake suitable for roughing operations?
Yes, the negative 0° rake provides a sturdy cutting edge that is well suited to interrupted cuts and robust roughing operations, improving edge strength and resistance to chipping.

What does the tolerance class M indicate?
Tolerance class M denotes standard dimensional accuracy for the insert, supporting reliable seating in compatible tool holders and consistent repeatability during indexings.
