RNGN150700T01020 WWS20 – Round Ceramic Turning/Milling Insert, Ø15 mm — Walter Tools

RNGN150700T01020 WWS20 is a round indexable insert designed for high‑speed, temperature‑resistant cutting in demanding machining operations

• Ceramic grade WWS20 for high cutting speeds
• Round insert Ø15 for form turning and profiling
• 0° negative relief angle for cutting stability
• Tolerance class G for consistent interchangeability

Optimised for high cutting speeds and thermal resistance

The insert is manufactured in the WWS20 cutting material, a ceramic grade optimised for high cutting speeds and elevated temperature stability. This composition reduces flank wear during hard or high‑temperature cuts and helps to maintain edge integrity in continuous operations. For workshops seeking to increase cycle rates on finishing or semi‑finishing passes, the thermal resilience of this grade offers a clear performance edge while allowing operators to exploit higher cutting parameters within the product matrix limits.

Geometry that delivers process reliability and accuracy

The round geometry with a nominal Ø15 mm size and corner radius 0 provides repeatable contact conditions and predictable chip formation for profiling tasks. The 0° negative relief angle ensures a robust cutting edge and reduces the risk of chipping when interrupted cuts occur. The tolerance class G ensures dimensional consistency across batches, supporting quick insert changes and maintaining positional accuracy in multi‑station turrets and milling heads.

Material suitability and application guidance

As a ceramic cutting material, the WWS20 grade is aimed at applications where hardness and heat resistance are primary concerns. Typical application areas include high‑speed finishing of difficult‑to‑cut alloys and where reduced chemical affinity between tool and workpiece is beneficial. The exact suitability depends on the machine capabilities and the workpiece material—users are advised to consult the manufacturer’s product matrix for optimal parameter selection and to validate performance in trial cuts before series production.

Productivity gains and economic considerations

Using a ceramic insert such as this often allows for higher cutting speeds and longer intervals between tool changes, which can translate into improved throughput and lower tool‑handling frequency. The combination of the WWS20 material and the insert’s geometry supports stable cutting under thermal load, contributing to predictable tool life and consistent surface quality. For operations targeting greater machining productivity without sacrificing surface integrity, this insert offers a pragmatic balance of performance and operational robustness.

FAQ

What materials is this ceramic grade intended for?
The WWS20 ceramic grade is intended for high‑speed and temperature‑resistant machining; suitability for specific workpiece materials should be checked against the product matrix and verified with trial cuts when using the RNGN150700T01020 insert.

How does the 0° negative relief angle affect performance?
A 0° negative relief angle on the RNGN150700T01020 insert produces a robust cutting edge that improves stability during interrupted cuts and reduces the likelihood of edge chipping under high mechanical load.

Can this insert be used for form turning and profiling?
Yes, the round Ø15 geometry is suited to form turning and profiling operations where a continuous cutting edge and predictable contact conditions are required.

What does tolerance class G mean for interchangeability?
Tolerance class G indicates consistent dimensional accuracy across production batches, enabling reliable interchangeability in turrets and indexable toolholders without additional re‑setting.

Is the coating specified for this insert?
No specific coating field is provided for this item; the grade is specified as Schneidkeramik (WWS20) and coating data is not listed in the available product fields.
