P2840S-7N-E67 WK40 drilling/boring indexable insert – 7N‑E67 chipbreaker, uncoated carbide (Walter Tools)

P2840S-7N-E67 WK40 is an indexable insert developed for drilling and boring operations in general machining where predictable chip formation and tool life are required

• WK40 uncoated carbide grade
• 7N‑E67 precision chipbreaker
• Designed for drilling and boring operations

Increased process throughput through stable cutting behaviour

The WK40 grade, supplied as an uncoated carbide, is specified to support productive metalcutting by promoting stable chip formation and consistent cutting geometry. The integrated 7N‑E67 chipbreaker works to break and evacuate chips reliably during both interrupted and continuous cutting cycles, which can reduce machine downtime caused by chip congestion. For operations where repeatability and predictable cycle times matter, this combination contributes directly to higher productivity and reduced process variability.

Predictable tool life and repeatable results for series production

By employing an insert from the Walter Tools “Serie offen”, the focus is on repeatable performance and straightforward tool management. The carbide substrate used here aims to provide robust cutting edges and resistance to microchipping in typical drilling and boring tasks. Where material-specific data is required, the tool’s suitability should be verified against the manufacturer’s product matrix; this ensures that expectations for tool life and surface finish align with the chosen workpiece material and machining parameters.

Compatibility and application guidance for engineering workshops

The insert’s designation and chipbreaker geometry indicate suitability for a range of drilling and boring set-ups within general machining. Because the material specification is catalog-dependent, the final selection should be based on tooling system compatibility and the targeted workpiece. The series configuration permits straightforward replacement and stock keeping in production environments. Where higher process security or a specific coating is mandated, alternative grades and coated variants should be considered to match operating speeds and cooling strategies.

Practical procurement and integration into the production chain

Parts such as this indexable insert are intended for efficient replenishment and predictable integration into tool holders and drilling bodies. The clear ISO-style designation facilitates ordering and inventory management; the open series design supports flexibility across similar applications. For workshops seeking to standardise inserts and reduce tooling complexity, this grade offers a balance between process reliability and operational simplicity, particularly in setups prioritising uninterrupted chip control.

FAQ

What machining tasks is this insert intended for?
The P2840S-7N-E67 WK40 insert is intended primarily for drilling and boring operations where controlled chip formation and predictable edge behaviour are required.

Is the insert coated or uncoated?
This insert is specified as an uncoated carbide grade (WK40) and is supplied in the open series; coatings and alternative grades should be selected based on the workpiece and process requirements.

How does the 7N‑E67 chipbreaker affect performance?
The 7N‑E67 chipbreaker promotes effective chip segmentation and evacuation during drilling and boring, supporting stable cutting and reducing the risk of chip-related interruptions.

Can the insert be used across different steels and non-ferrous materials?
Material suitability must be verified against the manufacturer’s product matrix; the grade offers general-purpose performance but specific process limits and recommended parameters depend on the workpiece material.

What information should be provided when ordering?
Provide the SKU (P2840S-7N-E67-WK40-WALTER), the insert designation, and the intended holder type to ensure correct matching and supply.
