SNGN120416TM-S WBK30 – Turning indexable insert, square 90°, CBN grade (Walter Tools)

A versatile indexable turning insert designed for hard and highly abrasive workpiece materials, offering a square 90° form and CBN cutting grade for reliable, high-performance turning operations

• CBN grade WBK30 for hardened materials
• Square 90° form, 1.6 mm corner radius
• Negative 0° rake for secure roughing
• Chipbreaker S for controlled chip formation

Consistent performance for hard turning and demanding operations

The CBN-based grade WBK30 provides a robust solution where conventional carbide wears prematurely. As a purpose-designed indexable insert, it delivers repeatable cutting performance in high-wear applications, translating to longer cycles between tool changes and improved uptime. The square 90° geometry, paired with a 1.6 mm corner radius, balances edge strength and accessibility for external turning, while the negative 0° rake offers added stability in interrupted cuts and heavy roughing. These engineered attributes reduce process variation and support predictable component tolerances in serial production.

Precision and chip control for safer machining cycles

The insert’s chipbreaker S promotes controlled chip formation, reducing the risk of long, entangling swarf that can interrupt automated machining. With a tolerance class G, dimensional consistency between inserts is ensured, supporting tight reproducibility on turned parts. For users less familiar with CBN, it is a superabrasive optimised for hard and highly abrasive alloys; suitability for specific workpiece materials should be confirmed against the product matrix to match grade and application. The combination of chip control and tolerance stability improves machining safety and reduces secondary operations.

Process security and economical tool life

Built for stable cutting in challenging materials, this insert helps to lower overall tooling costs by extending productive life relative to standard grades when used in appropriate applications. The WBK30 grade emphasises wear resistance, making it a cost-effective choice in high-volume or high-abrasion environments. Where process reliability is a priority, the insert’s geometry and material pairing reduce unplanned downtime and support consistent surface finish quality, enhancing both operational efficiency and output predictability.

Application guidance and selection tips

The insert is suited to hard turning and applications involving hardened steels or certain cast and superalloy materials, depending on the selected grade matrix. The designation indicates a square form with a 90° approach angle and a robust corner radius, making it appropriate for external turning and heavier cuts. When selecting tooling, verify the grade’s compatibility with the workpiece through the product matrix and consider cutting parameters that exploit CBN’s strength: moderate feed, appropriate depth of cut for the grade, and rigid fixturing. For tailored recommendations, technical consultation is available to align the insert grade with the machining task.

FAQ

What materials is this insert intended for?
The SNGN120416TM-S WBK30 is produced in a CBN grade intended primarily for hardened steels and highly abrasive alloys; compatibility should be verified against the product matrix for the exact application.

How does the chipbreaker affect machining?
The chipbreaker S promotes short, controlled chips that reduce swarf entanglement and improve process safety during turning operations.

Is the insert suitable for heavy roughing?
Yes. The negative 0° rake and the square 90° geometry provide stability for heavier cuts and interrupted cuts while maintaining edge strength.

What dimensional information is critical for tool setup?
Key data are the insert size (12 mm), corner radius (1.6 mm), thickness (4 mm) and the tolerance class G, which together determine seat fit and expected repeatability.

Can this insert be used for finishing passes?
The insert is optimised for robust turning; for fine finishing, selection of grade and cutting parameters should be guided by the desired surface finish and the material being machined.
