P2840S-7N-E77 WN15 — Bohr-/Aufbohrwendeschneidplatte by Walter Tools (uncoated carbide, 7N-E77 chipbreaker)

A Walter Tools P2840S-7N-E77 WN15 indexable insert designed for drilling and boring applications, offering robust chip control and predictable cutting behaviour in industrial machining environments

• Uncoated carbide grade WN15 for repeatability
• 7N-E77 chipbreaker for controlled chip formation
• Open series for a broad range of standard applications

Maximise machining consistency with controlled chips and stable performance

The insert is built on an uncoated carbide substrate to provide predictable cutting behaviour and a reliable cutting edge when used within its intended application range. The 7N-E77 chipbreaker is engineered to promote stable chip formation, which reduces interruptions in automated cycles and minimises the need for manual chip handling. For manufacturers seeking steady throughput, this results in fewer process deviations and a lower risk of unplanned downtime. Note that the exact suitability for specific workpiece materials must be verified against the product matrix supplied by Walter Tools.

Achieve productive cycles and repeatable tool life

With the WN15 grade, the focus is on repeatable cutting performance and productive machining rather than extreme high-speed finishing. The combination of this carbide class and the chip geometry supports longer intervals between indexings under appropriate cutting conditions, delivering a cost-effective approach to routine drilling and boring tasks. The insert’s geometry and grade are intended to make tool-life expectations consistent across batches, aiding planning and reducing variability in process outputs.

Integration guidance and application scope for machining shops

The P2840S-style designation indicates a standard indexable insert format compatible with common drilling and boring toolholders; workshop engineers can match the insert to existing holders that accept this ISO-style insert. Because the product is an uncoated grade, coolant strategy and cutting parameters should be adjusted according to the workpiece and the machining operation. If application-specific data or cutting parameter recommendations are required, Metav Werkzeuge can provide technical consultation and supply details to ensure proper integration into existing tooling setups.

FAQ

What materials is this insert suitable for?
Suitability depends on the specific workpiece and operation; the P2840S-7N-E77 WN15 insert is an uncoated carbide grade and the exact material suitability should be checked against the Walter Tools product matrix.

How does the 7N-E77 chipbreaker affect machining?
The 7N-E77 chipbreaker promotes controlled chip formation and evacuation, which contributes to more reliable cycle times and reduced manual intervention during drilling and boring operations when applied with appropriate cutting parameters.

Is this insert compatible with standard drill/boring holders?
The P2840S designation corresponds to a common indexable insert format; compatibility should be confirmed with the toolholder specification and the holder manufacturer’s recommendations.

Can the WN15 grade be used for high-speed finishing?
WN15 is an uncoated carbide grade optimised for repeatable performance and productive machining rather than specialised high-speed finishing; assess the application requirements and consult the product matrix for guidance.
