SNGN120712T01020 WIS10 – Turning indexable insert, SiAlON ceramic, square 90° – Walter Tools

The SNGN120712T01020 WIS10 is a square 90° indexable insert engineered for high-speed, temperature-resistant turning applications where reliable edge stability and repeatable results are essential

• SiAlON ceramic for high cutting speeds
• Square 90° geometry for secure clamping
• 1.2 mm corner radius for stable edge life

Engineered for predictable high-speed productivity

The insert is built on a SiAlON cutting ceramic grade, formulated for high cutting speeds and elevated temperature resistance. This ceramic base enables short cycle times when matched with the correct machining parameters and suitable coolant strategy. The negative 0° free angle (listed as 0° (negative)) contributes to a robust rake configuration that reduces the tendency to dig in under interrupted cuts, promoting stable chip formation and consistent tool life. When used within its intended ISO material groups, the design reduces process variability and helps to maintain throughput in serial turning operations.

Designed for process security and consistent surface quality

A square 90° geometry combined with a 1.2 mm corner radius delivers a balance between edge strength and the ability to produce repeatable surface finishes. The square form provides four indexed cutting edges, supporting economical re-indexing during production runs and lowering tooling expenditure per component. The modest corner radius helps avoid premature edge chipping while still permitting reliable dimensional control in semi-finish and finishing passes. These characteristics are particularly advantageous on machines where cycle time and reproducibility are measured performance indicators.

Clear guidance on material suitability and application

The insert belongs to the Walter Schneidstoffsorte series indicated as WIS10, a SiAlON-based grade intended for demanding, temperature-prone turning operations. The exact applicability depends on the workpiece material and the product matrix; therefore, verify the compatibility against the specified ISO material group before selecting cutting data. Note that the tool’s material reference is given as catalogue dependent, so recommended feeds, speeds and holder combinations should be taken from the official product matrix or confirmed with tooling specialists to ensure optimal life and surface integrity. For unfamiliar applications, technical consultation is advised to match insert geometry to the desired machining outcome.

FAQ

What materials is this insert suitable for?
The SNGN120712T01020 WIS10 insert is based on a SiAlON cutting ceramic designed for high-speed and temperature-resistant turning; material suitability must be checked against the product matrix for the appropriate ISO material group.

Is the 1.2 mm corner radius good for finishing?
A 1.2 mm corner radius provides a compromise between edge strength and surface quality; it is suitable for semi-finish and many finishing passes when correct feeds and speeds are applied to the SNGN120712T01020 WIS10.

How does the negative 0° rake affect machining?
The 0° (negative) rake enhances edge robustness and reduces the risk of insert breakage under interrupted cuts, contributing to process security and stable chip formation with this Walter Tools insert.

Can this insert be re-indexed to use all edges?
Yes, the square 90° geometry supplies multiple cutting edges that can be indexed to extend service life and lower tooling cost per component.

Where to find the recommended cutting data for this insert?
Refer to the Walter product matrix or request cutting data through Metav Werkzeuge; the SNGN120712T01020 WIS10’s best performance requires matching holder type and machining parameters to the specific application.
