CNGA120416T02020 WCK10 – Rhombic 80°, 1.6 mm nose radius indexable insert (Walter Tools)

The CNGA120416T02020 WCK10 is a rhombic 80° turning indexable insert intended for high-speed, temperature-resistant turning tasks where cutting-ceramic grades are required

• WCK10 cutting-ceramic grade for high-speed cutting
• Rhombic 80° geometry for versatile turning
• 1.6 mm nose radius for stable edge strength
• 0° negative relief for controlled chip formation

High-performance turning with ceramic-grade cutting

The insert is engineered around the WCK10 cutting ceramic, a grade specified for high-speed machining and temperature-resistant operations. This material choice enables shorter cycle times in appropriate applications by maintaining a stable cutting edge at elevated temperatures; the ceramic composition reduces flank wear under thermal stress and supports efficient removal rates. The rhombic 80° geometry together with the modest 1.6 mm nose radius provides a balance between edge robustness and fine surface finish, allowing productive roughing and reliable semi-finishing passes without compromising tool life.

Precision geometry and secure chip behaviour

With a rhombic 80° shape and 0° negative relief, the insert delivers consistent clamping stability and predictable chip flow in conventional turning holders. The negative relief aids in secure seating and repeatable cutting conditions, while the nose radius improves load distribution across the cutting edge. These geometric choices translate into reduced vibration and improved dimensional stability for workpieces. Where chip control is critical, the ceramic grade and geometry combine to produce compact, manageable chips under the right cutting parameters; actual behaviour depends on the chosen feed, speed and workpiece material, so refer to the cutting data matrix for optimal settings.

Application guidance and integration into the process

This indexable insert suits applications that demand thermal resilience and sustained cutting speeds; suitability for specific workpiece materials must be verified against the product matrix. The component is compatible with standard CNGA-type toolholders designed for rhombic 80° inserts and benefits from stable clamping systems. For process planning, expect advantages in productivity where high-speed machining is applicable, but check the cutting recommendations to align speed and feed with the insert’s ceramic characteristics.

FAQ

What materials is this insert suitable for?
Material suitability depends on the cutting matrix; the CNGA120416T02020 WCK10 insert uses a cutting-ceramic grade intended for high-speed and temperature-resistant turning—consult the product matrix for exact ISO material groups.

Can the CNGA120416T02020 WCK10 be used in standard CNGA toolholders?
Yes, the rhombic 80° form and size correspond to standard CNGA-type holders; ensure the holder supports inserts with negative relief and the correct thickness code.

How does the 1.6 mm nose radius affect surface finish and edge life?
A 1.6 mm nose radius increases edge strength and promotes longer edge life under load while providing a good compromise between robustness and achievable surface finish when appropriate feeds are used.

Is this insert suitable for continuous production at high cutting speeds?
The WCK10 cutting-ceramic is developed for high-speed machining and thermal stability; process parameters and workpiece material must be matched via the cutting data matrix to ensure optimal performance.
