P2840S-6N-E77 WN15 Drill/Bore indexable insert – 6N‑E77 chipbreaker | Walter Tools

The P2840S-6N-E77 WN15 is an indexable insert for drill and bore applications, designed to deliver controlled chip formation and reproducible cutting behaviour in a wide range of machining scenarios.

• Uncoated carbide grade WN15
• 6N‑E77 chipbreaker for reliable chip control
• Suitable for drilling and boring operations
• Walter open‑series cutting grade

Predictable chip control for uninterrupted production

The combination of the 6N‑E77 chipbreaker and the insert geometry provides stable chip formation, which reduces the risk of chip jamming and minimises downtime. This chip pattern is engineered to break and evacuate chips efficiently in through‑tool and conventional drilling, so the cutting process remains consistent even under varying feeds and depths. As a result, process reliability is improved and tool change frequency can be reduced, contributing to a smoother production flow.

Material and grade engineered for repeatable results

The insert is produced in the WN15 grade—an uncoated carbide designed for balanced wear behaviour across multiple material families. The uncoated microstructure offers predictable abrasion characteristics and good edge integrity under moderate cutting conditions. Material suitability depends on the specific workpiece; therefore, the product matrix should be consulted to confirm the optimal pairing of grade, cutting data and workpiece material. This ensures the chosen configuration meets both surface finish and tool life requirements.

Practical integration in drilling and boring tool systems

As a drill/bore indexable insert, the component is intended for systemised toolholders and modular drilling heads. Its geometry supports repeatable seating and accurate positioning, which helps maintain hole quality across tool changes. The insert’s features focus on efficiency: reduced vibration sensitivity through reliable chip control and stable cutting edges that contribute to consistent dimensional results. For machining planners, this means easier process standardisation and predictable output in series production.

FAQ

What machining operations is this insert designed for?
The insert is specified for drill and bore operations; the P2840S‑6N‑E77 WN15 supports standard drilling and boring tool systems where controlled chip formation is required.

Is the WN15 grade coated or uncoated?
WN15 is an uncoated carbide grade, chosen for consistent wear properties and reliable edge behaviour under appropriate cutting conditions.

What does the 6N‑E77 designation indicate?
The 6N‑E77 refers to the chipbreaker geometry—a design intended to produce short, controllable chips and to improve evacuation during drilling and boring operations.

Can this insert machine all workpiece materials?
Material compatibility must be confirmed in the product matrix; while WN15 offers broad applicability, checking the specific workpiece material against the manufacturer’s recommendations is essential.
