BCHT120430R-K85 WK10 milling indexable insert — Parallelogram 75°, K85 chipbreaker (Walter Tools)

The BCHT120430R-K85 WK10 is a parallelogram 75° milling insert engineered for general-purpose and batch milling where reliable chip control and repeatable edge performance are required

• Parallelogram 75° insert geometry
• K85 chipbreaker for stable chip control
• Uncoated carbide WK10 general-purpose grade
• 7° clearance for precise seating

Higher productivity through stable chip control and edge life

The combination of the K85 chipbreaker and the WK10 carbide grade is designed to promote stable chip formation, reducing interruptions in production and minimising rework. The chipbreaker geometry directs chips away from the cutting zone, which supports continuous machining cycles and helps maintain surface quality. For production managers and process engineers this means fewer stoppages and predictable output per tool life, improving throughput without complex process changes.

Precise geometry that supports repeatable tool clamping

A parallelogram 75° shape paired with a 7° clearance angle ensures secure seating in standard toolholders and a defined cutting edge engagement. The 3 mm corner radius balances edge strength with acceptable cutting forces, allowing consistent performance across repeated indexings. This geometry is suitable for a range of slotting and face milling applications where predictable tool behaviour and easy indexability matter for cycle-time planning.

Practical material choice and application guidance

The insert is supplied in the WK10 cutting grade, an uncoated carbide option listed in the Walter series. This grade is aimed at broad material coverage for general machining; however, suitability should be verified against the product matrix for specific workpiece materials and cutting parameters. The catalogue-dependent material specification means that selection can be matched to the intended operation, making it straightforward to align tool choice with process requirements while keeping procurement simple.

FAQ

What materials is this insert suitable for?
The BCHT120430R-K85 WK10 is supplied in the WK10 uncoated carbide grade; material suitability should be checked against the product matrix to confirm compatibility with specific steels, cast irons or non-ferrous materials.

How does the K85 chipbreaker affect machining?
The K85 chipbreaker promotes controlled chip formation and evacuation, which enhances process stability and helps maintain consistent surface finish during continuous milling operations.

What does the parallelogram 75° geometry help achieve?
The parallelogram 75° form provides defined cutting engagement and reliable clamping in compatible holders, improving repeatability when indexing the insert during production.

Is the WK10 grade coated?
WK10, as provided for this insert, is an uncoated carbide grade; this supports general-purpose use and can be selected where coating is not required for the application.

What dimension details should be confirmed before ordering?
Confirm the size designation (12), thickness code (04) and corner radius (3 mm) to ensure compatibility with the intended toolholder and machining strategy.
