P2840S-5N-E77 WN15 — Drill/bore indexable insert with 5N-E77 chipbreaker (Walter Tools)

The P2840S-5N-E77 WN15 is an indexable cutting insert designed for drilling and bore machining, combining a dedicated 5N-E77 chipbreaker with an uncoated carbide grade to deliver reliable chip formation and predictable cutting behaviour in a broad range of toolholder systems

• Uncoated carbide grade WN15
• Chipbreaker 5N-E77 for chip control
• Open series Walter cutting grade
• Designed for drilling and boring

Consistent chip control for uninterrupted machining

The principal advantage of this insert is its chip management: the 5N-E77 chipbreaker shapes and guides chips away from the cutting zone, reducing the risk of re-cutting and tool clogging. In practice, this leads to fewer machine stoppages and a steadier surface generation. The insert’s geometry and the uncoated WN15 composition support stable chip formation, which translates into improved process reliability and predictable tool-change intervals for production environments.

Economical and predictable performance in tool setups

As an element of the Walter open cutting-grade series, the insert offers a cost-effective option where uncoated carbide performance is preferred. Uncoated grades can be advantageous where coating adhesion is critical or where specific cutting conditions favour a bare carbide substrate. The grade and series should be matched against the product matrix in the catalogue to confirm the optimal application. This approach ensures repeatable results and supports efficient inventory management without sacrificing machining stability.

Easy integration and lower downtime in machining cells

Designed for use in common drill and bore toolholders, the insert permits straightforward indexing and replacement, reducing operator time at the machine. The combination of a defined chipbreaker and a consistent carbide substrate simplifies process parameter selection and shortens ramp-up time during tool changes. The open series designation further indicates broad applicability within Walter’s range, enabling easier replacement and compatibility checks in multi-shift production environments while contributing to overall process productivity and uptime.

FAQ

What distinguishes the WN15 grade from other carbide grades?
The WN15 grade is an uncoated carbide option in Walter’s open series, chosen for predictable cutting behaviour; the P2840S-5N-E77 WN15 insert benefits from that uncoated substrate when specific cutting conditions or coating constraints apply.

How does the 5N-E77 chipbreaker affect machining?
The 5N-E77 chipbreaker controls chip shape and evacuation during drilling and boring, helping to avoid chip entanglement and improving process stability with the P2840S-5N-E77 WN15 insert.

Is the insert suitable for all drill toolholders?
The insert is intended for integration into standard drill and bore toolholder systems; compatibility should be confirmed against the specific toolholder geometry and clamping system in use.

Can this insert be used where coated grades are usually recommended?
Coating selection depends on the specific workpiece material and cutting conditions; the uncoated WN15 grade can be preferable in situations where a bare carbide substrate is beneficial, but comparison with coated alternatives is advised via the product matrix.
