BCHT120408R-K85 WK10 milling insert by Walter Tools — parallelogram 75° geometry, K85 chipbreaker

The BCHT120408R-K85 WK10 is a precision milling insert designed for indexable milling applications where predictable chip formation and reliable tool life are required

• Parallelogram 75° geometry for flexible approach angles
• Uncoated carbide grade WK10 for cost-efficient performance
• Precision corner radius 0.8 mm for consistent edge control
• K85 chipbreaker for improved chip control and evacuation

Increased process efficiency through optimised geometry and chip control

The design of the insert focuses on measurable productivity gains: the parallelogram 75° geometry enables variable approach angles while keeping cutting forces favourable, and the integrated K85 chipbreaker promotes regular chip splitting and dependable evacuation. Together these characteristics lead to fewer interruptions for chip clearing and more consistent cycle times. Because the grade is WK10 (uncoated carbide) and the insert features a corner radius of 0.8 mm, the component offers a predictable balance between edge strength and cutting precision. For production planning, the tolerance class H supports reliable seat fit and repeatable indexability in standard tool holders.

Tool management simplified by standardised dimensions and robust design

Inventory and setup are simplified when inserts conform to standardised dimensions. The insert’s 12 mm size and thickness designation 04 make it straightforward to allocate across compatible milling cutters, and the parallelogram form reduces the number of special holders required. The relief angle of 7° and the precise geometry help maintain consistent surface finish and dimensional stability between index changes. As a result, tool changeover and requalification times are shortened, contributing to lower overall machining costs and smoother workflow in small- and medium-batch production.

Production security and application guidance for reliable results

Process reliability is supported by the open series specification Walter Schneidstoffsorte - Serie offen, which highlights the need to match the grade to the workpiece via the product matrix. The indexable design and the K85 chipbreaker combine to reduce the likelihood of random breakouts and to stabilise cutting conditions during long cycles. For ambiguous material choices or when working close to material limits, consult the manufacturer’s product matrix or the Metav Werkzeuge technical advisors to verify suitability. The result is a pragmatic solution for manufacturing environments that require repeatable performance without unnecessary complexity.

FAQ

What cutting tasks suit this parallelogram insert?
The insert is intended for milling operations where the parallelogram 75° geometry and K85 chipbreaker improve chip control and flexibility; verify specific workpiece compatibility with the product matrix before selecting the grade.

How should the insert be indexed and seated?
Index the insert according to the cutter manufacturer's instructions; the tolerance class H and the standardised size help ensure a secure, repeatable seat in compatible cutter bodies.

Is the WK10 grade coated or uncoated and what does that mean for wear?
The WK10 designation denotes an uncoated carbide grade; this typically offers cost-effective performance with reliable edge stability, while specific wear behaviour depends on the workpiece material and cutting parameters.

Can the insert be used for finishing as well as roughing?
With a corner radius of 0.8 mm and the 75° geometry, the insert can be applied to light finishing and general-purpose milling tasks; final surface quality and tolerances depend on cutting data and machine rigidity.

Where to find material compatibility information for this insert?
Material suitability is defined in the manufacturer's product matrix; consult the matrix or contact Metav Werkzeuge for application-specific recommendations regarding the BCHT120408R-K85 WK10.
