BCHT120404R-K85 WK10 milling indexable insert (Parallelogram 75°, K85 chipbreaker) — Walter Tools

The BCHT120404R-K85 WK10 is a milling indexable insert designed for general milling operations where consistent chip formation and predictable edge life are required

• Uncoated WK10 carbide grade
• K85 chipbreaker for consistent chip control
• Parallelogram 75° insert geometry
• 7° clearance angle and 0.4 mm corner radius

Productivity through predictable chip control

The combination of an uncoated carbide grade and a dedicated chipbreaker supports steady material removal and reduces cycle-time variability. The K85 chipbreaker is engineered to promote short, controllable chips in many common milling tasks, which helps to lower the risk of recutting and improves tool life. For operations where process stability and repeatable results matter, this insert provides a reliable edge performance that contributes to uninterrupted production and predictable tool-change intervals.

Geometry and edge stability for precise machining

A parallelogram 75° form and a 7° clearance angle ensure a secure cutting engagement and even load distribution across the cutting edge. The modest corner radius (0.4 mm) helps maintain a defined cutting edge that balances strength and surface finish, supporting both profile milling and general slotting where edge integrity is required. Tolerance class H contributes to consistent seating in the cutter body, so run-out and vibration are minimised and dimensional accuracy is easier to achieve.

Application guidance and selection criteria

The insert’s WK10 uncoated cemented carbide should be matched to the workpiece via the manufacturer’s product matrix to confirm suitability for specific materials and cutting conditions. As the grade is catalog-dependent, verification against the technical matrix is recommended prior to process implementation. The insert’s execution and chip control characteristics make it a pragmatic choice for shops seeking a cost-effective, hard-wearing solution for a range of milling tasks while retaining the option to step up to coated grades if higher wear resistance is required.

FAQ

What materials is this insert suitable for?
Material suitability must be checked against the Walter Tools product matrix; the WK10 grade is an uncoated carbide and the matrix indicates recommended materials and cutting conditions.

How does the K85 chipbreaker affect machining?
The K85 chipbreaker promotes controlled chip formation and reduced recutting, which enhances process stability and can improve tool life in many milling applications.

Can this insert be used in standard milling cutters with parallelogram pockets?
Yes, the parallelogram 75° geometry and tolerance class H are intended for compatible cutter bodies that accept this insert form and size.

What does the corner radius mean for surface finish?
A corner radius of 0.4 mm provides a balance between edge strength and achievable surface finish; it is suited to applications where a defined edge is required without excessive rounding.
