SNGN120412T02020 WCK10 — Indexable turning insert, 0° negative rake, 1.2 mm radius (Walter Tools)

SNGN120412T02020 WCK10 is an indexable turning insert intended for high‑speed and temperature‑resistant turning applications, featuring a square 90° geometry and a robust ceramic cutting grade.

• Ceramic grade WCK10 for high cutting speeds
• Square 90° geometry for stable engagement
• 0° negative rake for robust edge strength
• 1.2 mm corner radius for consistent finishes

Higher throughput thanks to a ceramic grade built for speed

The WCK10 ceramic grade is engineered for high‑speed machining and sustained performance at elevated temperatures. Its composition makes it suitable where conventional carbide grades lose edge integrity, enabling longer cycles between index changes and fewer unplanned interruptions. The combination of a temperature‑resistant cutting material and a defined insert form aims to increase effective cutting time, which translates into improved productivity for batch and series turning tasks.

Geometry engineered for stability and surface quality

A square 90° geometry delivers predictable tool engagement and stable cutting forces, while the 0° negative rake increases edge robustness for interrupted cuts or heavy engagement. The specified 1.2 mm corner radius helps produce a reliable surface finish and spreads cutting forces to reduce local wear. Together these geometric features support consistent component quality and make the insert a good option for operations demanding repeatable dimensional results.

Specification and selection guidance for correct integration

The insert is supplied as SNGN120412T02020 in the open Walter series and carries tolerance class G for dimensional precision and interchangeability. The designation and series description indicate a ceramic‑type cutting material; users should verify the specific ISO material group suitability in the product matrix before application. For holder compatibility, choose a turning tool that accepts the SNGN form and the thickness code 04; correct clamping and stable toolholding will fully leverage the insert’s thermal and mechanical strengths.

FAQ

What materials is this insert designed to machine?
The WCK10 ceramic grade is intended for high‑speed and temperature‑resistant machining; suitability for specific ISO material groups should be checked against the product matrix for the SNGN120412T02020 WCK10.

How does the 0° negative rake affect cutting behaviour?
A 0° negative rake increases edge strength and resistance to chipping, which benefits operations with interrupted cuts or tougher contact conditions when using the SNGN120412T02020 insert.

Why choose a square 90° geometry?
A square 90° geometry provides a stable cutting edge and predictable engagement angles, contributing to consistent dimensional control and easier toolpath planning when using this insert in turning applications.

What is the role of the 1.2 mm corner radius?
The 1.2 mm corner radius balances surface finish and tool life by distributing cutting forces over a larger area, reducing local stress and wear on the insert’s cutting edge.

What does tolerance class G mean for interchangeability?
Tolerance class G indicates standardised dimensional precision for the insert, aiding in reliable replacement and interchange between compatible toolholders and ensuring predictable mounting and runout behaviour.
