P2840S-2N-E77 WNN15 drill/reamer indexable insert by Walter Tools — 2N-E77 chipbreaker, coated carbide

A P2840S-2N-E77 WNN15 indexable insert engineered for drilling and boring applications, offering a coated carbide construction and a 2N-E77 chipbreaker for controlled chip formation and reliable machining.

• Coated carbide grade WNN15 for wear resistance
• 2N-E77 chipbreaker for controlled chip formation
• Open-series Walter grade for broad material use
• Optimised for productive drilling processes

Improved process stability through precise chip control

The combination of the 2N-E77 chipbreaker and the coated carbide grade delivers notably consistent chip formation during drilling and boring tasks. This geometry supports stable evacuation of chips, which reduces the risk of built-up edge and unexpected interruptions. As a result, cycle times can remain steady and the machining process becomes more predictable. The insert’s configuration is particularly suited to operations where repeated, reliable hole-making is required and where minimised rework represents a clear efficiency gain.

Clear guidance on material suitability and selection

The cutting material is a coated carbide (WNN15) that provides enhanced wear resistance under demanding cutting conditions; however, material suitability should be verified against the specific product matrix provided for the grade. This step ensures the best match between the insert and the workpiece material. By checking the matrix, operators can confirm whether the grade aligns with the intended application—reducing the risk of premature wear and securing consistent surface quality in the finished component.

Compatibility considerations and handling benefits

Designated as P2840S-2N-E77, this indexable insert fits drill and reamer cutter bodies configured for that designation; the standardised form simplifies replacement and inventory management. The defined seating and chipbreaker design support repeatable positioning, which helps shorten tool-change times and reduces setup variability. When mounted in a compatible holder, the insert enables straightforward maintenance of cutting geometry and contributes to predictable production output.

Why Walter Tools’ open-series grade is a dependable choice

Walter Tools’ open-series grade focuses on broad applicability and dependable cutting performance, supporting productive machining where versatility is valued. The grade’s coated carbide composition aims to balance wear resistance with edge stability, promoting longer tool life when matched correctly to the application. Choosing this insert means selecting a component designed with process reliability in mind, which can help ensure consistent results across series production runs.
