SNGA120408T02020 WCK10 – indexable turning insert, square 90° with 0.8 mm corner radius (Walter Tools)

A SNGA120408T02020 WCK10 indexable turning insert engineered for temperature-resistant, high-speed turning applications where stable cutting and accurate profile formation are required

• Square 90° insert for versatile turning
• WCK10 cutting ceramic for high-speed cuts
• 0.8 mm corner radius for precise profiles
• Negative 0° rake for stable chip formation

High-speed performance with temperature-resistant cutting material

The open-series WCK10 grade is a cutting ceramic developed for elevated cutting speeds and temperature-stable operations. In practice, the ceramic matrix sustains harder cutting zones and reduces wear under thermal stress, which translates into longer effective tool life and fewer interruptions for index changes. The material selection is particularly beneficial where cycle time reduction is a priority; machining parameters should be aligned with the specific ISO material group indicated in the product matrix to ensure optimal results. Emphasis on thermal stability offers a clear productivity advantage in continuous turning processes.

Geometry designed for repeatable profiles and edge security

A square 90° format combined with a 0.8 mm corner radius delivers controlled engagement and consistent profile reproduction on turned components. The insert’s geometry supports stable cutting forces, which helps maintain surface quality and dimensional repeatability across workpieces. The designation for thickness (04) is a standard code for the insert series and should be checked against toolholder compatibility; the negative 0° rake contributes to a secure cutting edge and improved chip control, reducing vibration in heavy or interrupted cuts. Together, these features ease process planning and support reliable batch production.

Process security, tool life and application guidance

The open-series philosophy of the grade offers broad applicability across suitable workpiece materials — check the product matrix for precise ISO matches. The insert’s construction and negative rake orientation foster stable chip formation, which enhances insert life and reduces the frequency of tool changes. For production environments seeking consistent results, the combination of thermal resistance and robust geometry provides a balanced solution between performance and service life. For application-specific parameter recommendations or material compatibility, Metav Werkzeuge’s technical consultants provide targeted guidance based on machining goals and equipment.

FAQ

What materials is this insert suitable for? The SNGA120408T02020 WCK10 insert is based on a cutting ceramic grade intended for high-speed, temperature-resistant turning; compatibility should be determined from the product matrix against the relevant ISO workpiece group.

How does the negative 0° rake affect machining? A negative 0° rake increases edge strength and promotes stable chip formation, making the insert well suited to interrupted cuts and operations demanding edge security.

Which toolholder types are compatible with this square 90° insert? Compatibility depends on the toolholder pocket and the thickness designation (04); holders designed for 90° square inserts with matching seating dimensions are required for correct clamping and repeatability.

Can this insert improve cycle times in production turning? The WCK10 ceramic grade is optimised for elevated cutting speeds; when used within recommended parameters for the target ISO group, the insert can reduce cycle time through higher allowable cutting speeds.

How is the corner radius relevant to surface quality? The 0.8 mm corner radius balances profile accuracy and edge strength; it helps produce repeatable surface finishes while avoiding excessive stress concentration on the cutting edge.
