Drill/Reamer indexable insert P2840S-2N-E77 WN15 by Walter Tools

The P2840S-2N-E77 WN15 is an indexable insert for drilling and bore‑enlarging operations, engineered for stable chip formation and repeatable performance in demanding machining sequences

• Uncoated carbide grade WN15
• 2N‑E77 chipbreaker for stable chip control
• Walter open grade series for broad tasks
• Precision fit for repeatable machining

Consistent chip control reduces process interruptions

The insert’s defining element is the 2N‑E77 chipbreaker, designed to maintain stable chip formation across varying depths of cut. Stable chips reduce the frequency of manual intervention and minimise the risk of toolholder blockage, which supports uninterrupted machining cycles. For shops aiming to improve first‑pass yield, the combination of a controlled chip form and a sharp cutting edge leads to fewer tool changes and a more predictable process window. The chip management benefit is particularly relevant when several consecutive holes are required or when subsequent operations are sensitive to swarf accumulation.

Uncoated carbide grade for reliable cutting performance

Constructed in the WN15 uncoated carbide grade from the Walter open series, this insert offers a balance between edge life and economical usage. Uncoated carbide provides a sharp, wear‑resistant cutting edge that is well suited to general holemaking tasks; the grade selection supports good edge stability and reproducible results. While the specific material suitability should be verified against the product matrix, the open grade concept is intended to deliver broad applicability and straightforward reconditioning. Using a consistent carbide grade across multiple diameters simplifies inventory and helps maintain process stability.

Designed for predictable integration into machining processes

The insert’s geometry and finish ensure accurate seating and repeatable indexability, which contributes to repeatable performance across production batches. When integrated with suitable drill bodies or reaming holders, the design reduces positional variation and promotes consistent hole quality. Specification details such as the ISO designation and series coding enable straightforward matching with tooling systems and spare parts management. For customers requiring process assurance, documented insert identification supports traceability and easier tool life comparisons between runs.

FAQ

What materials is the insert suitable for?
Material suitability must be checked against the manufacturer's product matrix; the WN15 grade is an uncoated carbide designed for broad tasks, but specific workpiece materials require verification.

How does the 2N‑E77 chipbreaker affect hole quality?
The 2N‑E77 chipbreaker improves chip control and reduces swarf entanglement, which supports cleaner holes and fewer process interruptions when used in appropriate drilling and bore‑enlarging setups.

Can the insert be reground or reconditioned?
The insert geometry and uncoated carbide nature of WN15 allow for reconditioning in many cases; regrinding should follow the manufacturer's recommendations to preserve the intended cutting geometry.

Is the P2840S‑2N‑E77 WN15 compatible with existing Walter holders?
The ISO designation and series coding facilitate compatibility checks; match the P2840S‑2N‑E77 WN15 to the appropriate drill or reaming body in accordance with product documentation.

What benefits does the Walter open series offer?
The Walter open series is intended for versatile application scenarios, offering a practical combination of edge stability and process flexibility for general holemaking tasks.
