BCHT120420R-K85 WK10 Milling Insert (Parallelogram 75°) — Walter Tools

The BCHT120420R-K85 WK10 is a parallelogram milling indexable insert engineered for dependable chip formation and productive face and shoulder milling in a wide range of shop environments.

• Uncoated carbide grade WK10
• K85 chipbreaker for stable chips
• Parallelogram 75° geometry
• 7° clearance angle for reduced rubbing
• Corner radius 2 for precise edge engagement

Predictable chip control for efficient processes

The insert is built from WK10 uncoated carbide, a material class suited for general milling where a stable, predictable cutting edge is required. Combined with the K85 chipbreaker, the insert delivers consistent chip control, reducing rework and interruptions. The geometry, being a parallelogram 75°, promotes favourable cutting forces in many milling operations; as a result, cycle times can be reduced while maintaining surface integrity. The design supports reliable tool life and process stability under routine production loads.

Designed to increase productivity and repeatability

A low clearance angle of 7° and a corner radius 2 ensure clean engagement with the workpiece and help to lower friction at the cutting edge. This arrangement enables a balance between load capacity and surface finish, which is particularly relevant for machines aiming for both throughput and quality. The indexable nature of the insert allows for rapid seat changes and consistent repositioning, so toolholders can be brought back into-cut with minimal setup time. The outcome is a measurable improvement in machining uptime and repeatable part quality.

Simple selection and secure handling in the workshop

Specification data is presented clearly to assist engineering decisions: ISO designation BCHT120420R-K85 WK10, chipbreaker K85, and thickness code 04. Compatibility with toolholders that accept the parallelogram 75° form is recommended; the insert’s format supports straightforward mounting and indexation. For material suitability, the product matrix should be consulted to match the WK10 grade to the intended workpiece material and cutting parameters. Technical enquiries can be addressed through Metav Werkzeuge for tailored recommendations and cutting data.

FAQ

Is this insert suitable for finishing and roughing applications?
The BCHT120420R-K85 WK10 insert is designed for general milling tasks where a balance between finish and productivity is needed; suitability for a specific finishing or roughing task should be verified against the product matrix.

What does the WK10 grade indicate?
WK10 denotes an uncoated carbide grade from Walter Tools intended for a broad range of milling operations; the grade’s performance will depend on cutting parameters and workpiece material.

How does the K85 chipbreaker affect performance?
The K85 chipbreaker promotes stable chip formation and evacuation, improving process reliability and reducing the risk of chip-related interruptions during machining.

Can the insert be indexed to restore a sharp edge?
Yes, the parallelogram insert is indexable; repeated indexing provides multiple usable cutting edges and supports consistent repositioning in the toolholder.
