BCHT120440R-K85 WK10 Fräswendeschneidplatte — Parallelogram 75°, K85 chipbreaker (Walter Tools)

BCHT120440R-K85 WK10 is a precision milling insert designed for general face milling applications where consistent chip formation and predictable tool life are required

WK10 uncoated carbide grade
Parallelogram 75° geometry
K85 chipbreaker for controlled chips
7° relief angle for secure cutting

High-performance substrate for consistent machining productivity

The insert features the WK10 uncoated carbide substrate, a composition optimised for stable cutting under a range of conditions. This uncoated carbide provides predictable wear behaviour and simple reconditioning options, making it suitable where consistent edge performance is more important than advanced coating technology. The result is a cost-effective compromise between tool life and machining economy, supporting shorter set-up times and stable process windows. For operations that prioritise repeatable results, the substrate class offers a clear advantage in planning machining cycles and replacement intervals.

Geometry and chip control that support efficient milling

The parallelogram 75° shape combined with the K85 chipbreaker delivers controlled chip flow and reliable engagement in face milling tasks. The 7° relief angle reduces rubbing at the flank, improving surface integrity while the shaped chipbreaker channels swarf efficiently away from the cutting zone. Together these features reduce the risk of built-up edge and help maintain consistent surface finish across a workpiece. Engineers will note improved operational stability on medium-duty passes, where chip control directly influences cycle time and part quality.

Design robustness and tolerance for workshop integration

Manufactured to tolerance class H, the insert’s dimensional stability supports repeatable indexing and predictable seat fits in compatible milling bodies. The plate’s corner radius and thickness codes are selected to balance strength and accessibility in confined geometries; this leads to fewer interruptions for insert changes and a lower incidence of incidental edge damage. Compatibility with standard clamping systems and common toolholders makes the component straightforward to adopt within established tool assortments, simplifying tool management and stock keeping.

Practical application advice and process considerations

Selection of this insert should be guided by the workpiece material and the specific cutting parameters: WK10 is an uncoated carbide grade whose suitability depends on the product matrix for individual materials. For roughing passes where chip evacuation and edge robustness are critical, the K85 chipbreaker excels; for finishing, reducing feed per tooth and adapting cutting speed will maximise surface quality. If clarification is needed on the best speeds and feeds for a particular alloy or machining centre, process engineers and toolroom planners can request tailored recommendations to ensure optimal performance.

FAQ

What materials is this insert suitable for?
Suitability depends on the application matrix; the BCHT120440R-K85 WK10 is an uncoated carbide insert and its applicability should be checked against the workpiece material and cutting conditions.

How does the K85 chipbreaker influence machining?
The K85 chipbreaker promotes controlled chip formation and evacuation, supporting stable cutting and improved surface integrity during face milling operations.

What does the parallelogram 75° geometry change in practice?
A parallelogram 75° geometry alters the entry angle and engagement, improving accessibility for certain toolpaths and enabling consistent cutting forces across the arc of contact.

Is the insert compatible with standard milling holders?
The insert is manufactured to tolerance class H and is intended for holders designed for the BCHT geometry; confirm holder compatibility by matching the base designation and seat form.
