SCGW09T308TS-4 WBK20 – CBN indexable turning insert (square 90°) by Walter Tools, for hard, wear‑intensive machining

The SCGW09T308TS-4 WBK20 is a square 90° indexable turning insert intended for wear‑resistant operations on hardened steels and similar demanding materials, offering a balance of durability and consistent cutting performance.

• CBN grade WBK20 for hard, wear‑intensive machining
• Square 90° form with 0.8 mm corner radius
• 7° clearance angle for consistent cutting performance
• Chipbreaker 4 and T3 plate thickness

Increased productivity through CBN wear resistance

The CBN composition of the WBK20 grade is engineered for hard, highly abrasive turning operations, which translates into longer tool life and fewer changeovers on heat‑treated components. Cubic boron nitride excels where conventional carbides wear quickly; using a CBN insert reduces unscheduled downtime and improves process stability. For production environments with frequent hard material work, the insert’s wear resistance can deliver measurable productivity gains and more predictable tool‑life cycles.

Geometry that stabilises cutting and finish

A square 90° form combined with a 0.8 mm corner radius and a 7° clearance angle provides mechanical stability and repeatable contact geometry, which helps to achieve a reliable surface finish on turned parts. The corner radius controls edge strength and influences cutting forces; a modest radius like 0.8 mm balances robustness and the ability to produce precise contours. The clearance angle reduces rubbing and heat build‑up, contributing to consistent tool behaviour over longer runs.

Controlled chips and simple integration into existing toolholders

The chipbreaker 4 design and T3 plate thickness support stable chip control in many finishing and semi‑finishing operations where CBN is appropriate. Although the insert is optimised for hard, wear‑intensive applications, compatibility with specific workpiece materials should be confirmed against the product matrix to ensure the right grades and cutting data are selected. The insert is supplied in a standard square form that fits common clamping systems, enabling straightforward adoption in established turning setups.

FAQ

What materials is this insert intended for?
The SCGW09T308TS-4 WBK20 insert is a CBN grade designed primarily for hardened steels and other hard, wear‑intensive materials; final suitability should be checked in the product matrix.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius on this insert increases edge strength and stabilises cutting forces, which helps produce a consistent surface finish while offering improved resistance to chipping.

Can the insert be used in existing toolholders?
The insert is a standard square 90° form that fits common clamping systems; ensure correct seat and clamping geometry for optimal performance with the SCGW09T308TS-4 WBK20.

What benefit does chipbreaker 4 provide?
Chipbreaker 4 is intended to improve chip control under the insert’s recommended cutting conditions, contributing to safer chip removal and more reliable turning cycles.

Is there any special handling or inspection recommended for CBN inserts?
CBN grades like WBK20 require careful control of cutting parameters and regular inspection for edge wear; inspect the SCGW09T308TS-4 WBK20 for flank wear and edge integrity at set intervals during production.
