Drehwendeschneidplatte CNMG120404-FW5 WPP20G – indexable insert for general turning with Tiger·tec Gold coating

CNMG120404-FW5 WPP20G is a rhombic 80° turning insert designed for versatile steel turning, combining a coated carbide grade and an FW5 chipbreaker for stable machining.

• Tiger·tec Gold coated carbide grade WPP20G
• FW5 chipbreaker for consistent chip control
• Rhombic 80° geometry for versatile turning
• Negative 0° rake with 0.4 mm corner radius

High productivity through wear-resistant cutting performance

The combination of coated carbide in the Tiger·tec Gold family and the WPP20G grade delivers improved wear resistance and a longer effective tool life when machining ISO group P (Stahl) materials. The coating technology reduces flank wear and thermal load at the cutting edge, which translates into fewer indexings and a smoother production flow. For operations where consistent edge life and process stability matter, this insert offers a measurable productivity gain while maintaining machining reliability.

Controlled chip formation and surface quality

The FW5 chipbreaker is engineered for stable chip control during turning; it actively shapes chips for reliable evacuation and reduces the risk of built-up edge. The rhombic 80° form, together with the negative 0° rake, helps to moderate cutting forces while enabling robust engagement in general turning tasks. The corner radius 0.4 mm contributes to an improved surface finish by supporting a stronger edge, especially in finishing and general-purpose applications where balanced geometry improves part consistency.

Application range and compatibility with standard toolholders

Designed according to common CNMG specifications, the insert fits standard CNMG toolholders and is intended primarily for machining P (Stahl)—covering unalloyed and alloyed steels that generate typical heat and chip conditions in turning. The CNMG120404-FW5 WPP20G is therefore suitable for a wide range of workshop and production tasks, from roughing operations under controlled conditions to light finishing where surface integrity is valued. Selection of carbide grade and chipbreaker helps to match the cutting conditions without overcomplicating holder or machine setup.

Economic advantages and selection guidance

Using a coated grade such as WPP20G can reduce the total cost per component by extending index life and lowering downtime for insert changes. The modest corner radius and neutral rake provide a compromise between edge strength and surface quality, reducing the need for multiple specialised inserts. For optimal results, pair the insert with appropriate feed and speed parameters for the workpiece class and consider the Tiger·tec Gold benefits where longer runs or variable batch sizes demand consistent performance.

FAQ

What workpiece materials is this insert best suited to machine?
The CNMG120404-FW5 WPP20G insert is optimised for ISO group P, i.e. a range of Stahl materials such as unalloyed and alloyed steels, providing stable performance under typical steel turning conditions.

How does the FW5 chipbreaker affect chip formation?
The FW5 chipbreaker on the CNMG120404-FW5 WPP20G shapes chips for reliable evacuation and reduced risk of entanglement, improving process stability in continuous turning operations.

Can this insert be used for finishing operations?
Yes; the rhombic 80° geometry combined with a corner radius of 0.4 mm on the CNMG120404-FW5 WPP20G supports acceptable surface quality for light finishing, while maintaining edge strength.

Is the Tiger·tec Gold coating suitable for high-temperature cutting?
The Tiger·tec Gold coating on the WPP20G grade enhances resistance to thermal wear and oxidation, making the insert appropriate where heat generation is a factor during continuous cutting of Stahl.

Which toolholders are compatible with this insert designation?
The CNMG format follows standard industry dimensions and therefore fits common CNMG toolholders designed for rhombic 80° inserts; verify holder clamping type and insert seat for exact compatibility.
