CNMG090308-FP5 WPP20G turning insert — Walter Tools, rhombic 80° geometry, negative 0° rake

CNMG090308-FP5 WPP20G is a rhombic 80° indexable insert designed for productive turning of steels in ISO P applications

• Tiger·tec Gold coated carbide grade WPP20G
• Designed for machining steel (ISO P)
• Rhombic 80° geometry with 0.8 mm corner
• FP5 chipbreaker for controlled chips

Higher throughput for steel turning with stable wear behaviour

The Tiger·tec Gold coating in combination with the WPP20G grade provides a balance between wear resistance and toughness that is optimised for steel machining. This results in consistent cutting performance across common steel grades and reduces unplanned tool changes. The FP5 chipbreaker ensures reliable chip formation, lowering the risk of chip-related interruptions and improving cycle times. Compared with uncoated solutions, the coated carbide promotes longer life and more predictable tool behaviour under varied cutting parameters.

Improved surface finish and process security through chip control

A controlled chipflow from the FP5 chipbreaker contributes directly to surface quality and machine uptime. The rhombic 80° shape and the negative 0° rake stabilise the cutting edge under oscillating cuts, which helps maintain repeatable surface finishes on turned components. As a result, setup effort and downstream rework are reduced, delivering measurable gains in productivity for batch and continuous operations where consistent part quality is required.

Robust edge geometry for extended tool life and reliable tolerance adherence

The 0.8 mm corner radius and tolerance class M are chosen to combine edge strength with acceptable fine-finishing capability. This geometry offers resistance to edge chipping during interrupted cuts and when machining tougher steels, while still allowing satisfactory dimensional control. The insert’s construction as a coated cemented carbide makes it suitable for sustained use in standard turning tasks where both longevity and reproducible performance matter.

Practical selection advice and integration into machining processes

The insert is intended primarily for ISO P (steel) applications and integrates easily into tool holders that accept CNMG-style inserts. For users transitioning from other grades, the WPP20G is positioned as a universal choice with emphasis on process reliability. For tool-life extension, consider optimising feed and cutting speed based on material hardness; small adjustments often yield substantial improvements in overall cost per component. If further machining parameters are required, technical consultation is available.

FAQ

What materials is this insert suitable for?
The CNMG090308-FP5 WPP20G is formulated for ISO P applications and is intended primarily for turning various steels.

What advantage does the Tiger·tec Gold coating provide?
Tiger·tec Gold on the WPP20G grade improves wear resistance and heat protection, supporting longer tool life and stable performance when machining steel.

How does the FP5 chipbreaker affect machining?
The FP5 chipbreaker produces controlled chip formation, which helps maintain surface quality and reduces the likelihood of chip entanglement during turning operations.

Is the negative 0° rake suited to interrupted cuts?
Yes, the negative 0° rake and the 0.8 mm corner radius enhance edge strength, making the insert robust for interrupted cuts and applications with varying engagement.

What geometry and holder compatibility should be expected?
The insert is a CNMG-style rhombic 80° indexable insert; it fits standard tool holders designed for CNMG inserts and benefits from holders that secure the negative-rake geometry.
