Fräswendeschneidplatte BCHT120412R-K85 WK10 – Parallelogram 75°, 7° clearance (Walter Tools)

BCHT120412R-K85 WK10 is a milling indexable insert designed for general milling operations where reliable chip control and predictable tool life are required

• Uncoated carbide grade WK10
• K85 chipbreaker for stable chips
• Parallelogram 75° geometry
• 7° clearance angle

Consistent chip control for stable production

The insert’s defining element is the K85 chipbreaker combined with the WK10 uncoated cemented carbide grade, engineered to support stable chip formation during interrupted and continuous milling. The chipbreaker reduces the tendency for long, tangled swarf by fragmenting chips into manageable lengths; this improves process reliability and reduces secondary handling. For machine shops pursuing steady cycle times, the result is fewer interruptions and a more predictable production flow.

Geometry that balances strength and cutting access

The parallelogram 75° profile provides an effective compromise between edge strength and cutting accessibility on shoulder and face milling applications. The insert’s 1.2 mm corner radius enhances edge robustness, offering better resistance to edge chipping under moderate depths of cut and intermittent engagement. At the same time, the 7° clearance angle lowers flank contact, helping to reduce rubbing and heat buildup while maintaining a clean cutting line and consistent surface quality.

Material and grade explained for confident selection

The grade WK10 denotes an uncoated cemented carbide composition intended for broad applicability; users should consult the product matrix to confirm suitability for specific workpiece materials. Uncoated grades provide straightforward cutting behaviour and can be advantageous where coating adhesion or thermal transfer characteristics might affect finish or dimensional results. In practical terms, this makes the insert a pragmatic choice for workshops that require flexible tool management across diverse tasks.

Practical benefits in daily workshop use

With a compact 12 size and execution T, the insert fits established toolholders and allows rapid index changes to restore cutting geometry. The combination of chip control and robust edge geometry reduces downtime for insert changes and rework, supporting higher overall equipment effectiveness. For operations seeking a dependable, easy-to-plan tooling option, the insert represents a technically clear, cost-conscious component that integrates into standard milling setups.
