P2840S-4N-E77 WN15 indexable drill/reamer insert — Walter Tools

A P2840S-4N-E77 WN15 indexable cutting insert designed for drilling and hole-enlarging operations, offering controlled chip formation and reliable edge geometry for industrial machining tasks

• Uncoated carbide grade WN15
• 4N‑E77 chipbreaker for controlled chips
• Suitable for drilling and boring inserts
• Walter Tools quality and consistency

Controlled chip formation for consistent process reliability

The insert is specified with the 4N‑E77 chipbreaker, which promotes stable chip formation and predictable evacuation during drilling and reaming cycles. This engineered chip control reduces the risk of packing or jamming in deep-hole or interrupted cuts, supporting more reliable cycle times on production lines. As the cutting material is defined as WN15 — an uncoated carbide grade within the Walter series — operators can expect a balance between edge life and economical tooling costs; however, material compatibility should be verified in the product matrix before application.

Indexable design that reduces tooling costs and setup time

Using an indexable format, the insert eliminates the need for full-tool replacement when the edge is spent: corners can be rotated and the insert reused, cutting overall tooling expenditure. The geometry is optimised for drilling/reaming profiles, offering repeatable cutting performance and simplified changeover procedures. For workshops aiming to improve throughput while keeping inventory lean, the indexable approach offers tangible savings and faster machine uptime compared with solid tooling alternatives.

Practical integration and selection guidance for production use

Specification details such as series and chipbreaker are documented to ease selection: the P2840S‑4N‑E77 designation indicates the insert family and the WN15 grade within Walter Tools' open series. Because the grade is catalogue-dependent and the manufacturer recommends checking the product matrix, the final choice should be matched to workpiece material and cutting parameters. For additional guidance on recommended speeds, feeds and clamping, Metav Werkzeuge can provide the necessary cutting data and application advice to ensure optimal performance.
