CNMQ080508-A57T WPP35G rhombic 80° milling insert, Tiger·tec Gold coating for steel — Walter Tools

The CNMQ080508-A57T WPP35G is a negative 0° rhombic 80° indexable milling insert designed for efficient steel machining with controlled chip formation.

• Tiger·tec Gold coating for extended tool life
• Optimised for steel machining (ISO group P)
• Rhombic 80° shape with 0.8 mm corner radius
• Negative 0° clearance for secure chip control

High-performance cutting for steel components

The coated cemented-carbide grade WPP35G, paired with the Tiger·tec Gold technology, provides a balance of wear resistance and toughness specifically tailored to steel applications (ISO group P). The combination of a rhombic 80° geometry and a 0° negative rake angle stabilises the cutting edge under typical steel machining temperatures, which results in consistent surface finish and reduced process variability. For machining centres and robust milling operations, this insert delivers predictable flank wear and allows longer intervals between indexing, directly supporting higher machine uptime and stable production.

Precise chip control and process reliability

Equipped with the A57T chipbreaker, this insert promotes controlled chip formation and evacuation in through-cut and profile milling of steels. The 0.8 mm corner radius enhances edge strength and contributes to improved tool life when encountering interrupted cuts or variable workpiece hardness. The negative geometry combined with the chipformer design reduces vibration and the risk of built-up edge, which helps to maintain dimensional stability across series parts. Operators and process engineers benefit from a reduction in unscheduled stops and an increase in reproducible results across shifts.

Long-term economy through consistent wear behaviour

By focusing on a coated grade that is optimised for common steel alloys, the insert supports cost-effective production: fewer indexings, less scrap from surface defects and steadier tolerance adherence over tool life. The Tiger·tec Gold coating improves resistance to flank and crater wear while the substrate provides the toughness needed for interrupted cutting, leading to a favourable lifecycle cost per workpiece. For procurement and planning, using a standardised insert geometry like the rhombic 80° simplifies tool holding setups and inventory management, contributing to lower overall process costs without compromising on component quality.

FAQ

What materials is this insert suitable for?
The CNMQ080508-A57T WPP35G is formulated for machining steel (ISO group P), including unalloyed and alloyed steels.

How does the A57T chipbreaker improve milling performance?
The A57T chipbreaker on this insert supports controlled chip formation and evacuation, reducing the likelihood of long, entangling chips and improving process stability during steel milling.

What benefit does the rhombic 80° geometry provide?
A rhombic 80° geometry offers a favourable balance between strength and accessibility for shoulder and face milling, aiding stable cutting and straightforward toolholder compatibility.

Is the coating suitable for interrupted cuts?
Yes; the Tiger·tec Gold coating combined with the substrate toughness of the WPP35G grade is designed to withstand the thermal and mechanical demands of interrupted cutting in steel.

How does the 0.8 mm corner radius affect component finish?
A 0.8 mm corner radius increases edge robustness and helps maintain a consistent surface finish while reducing the risk of chipping on entry or exit.
