P4840C-6R-E67 WXP40 – Drilling/Reaming indexable insert, chipbreaker 6R‑E67, Walter Tools

The P4840C-6R-E67 WXP40 is a drilling and reaming indexable insert engineered for machining centres and toolholders where stable chip evacuation and predictable performance are required.

• Uncoated carbide grade WXP40
• Chipbreaker 6R‑E67 for controlled chips
• Suited to drilling and reaming operations

Improved hole quality through focused chip control

The insert’s geometry and chipbreaker 6R‑E67 combine to produce stable chip formation, which reduces the risk of rework and contributes to repeatable hole quality. For practical workshop use, this means fewer interruptions from chip jams and more consistent cycle times when producing batches of components. The built-in chip control is particularly beneficial where tight tolerance holes are required, because it supports a steady metal removal process and minimises the risk of edge damage.

Productivity gains from a robust uncoated grade

Made in the WXP40 family—an uncoated carbide grade—the design focuses on durability and economical performance in a wide range of applications. The combination of substrate and geometry aims to deliver extended tool life under stable cutting conditions, enabling longer runs between index changes. For production environments prioritising uptime, the insert helps to keep machines running and reduces the frequency of stoppages for insert replacement.

Practical application and process security

The insert is intended for drilling and reaming tool assemblies and integrates with standard toolholders used in CNC machining centres. Its characteristics support a safe and predictable process window, promoting process security and consistent surface finish in the machined holes. Operators benefit from easier process setup because the insert’s behaviour under cutting is governed by its chip control and carbide grade, allowing more reliable parameter selection and reduced test time.

Selecting the right insert for the task

When choosing this type of indexable insert, consider the workpiece material and the required hole tolerance. The WXP40 grade is supplied as an uncoated carbide option—check the specific product matrix for the exact material suitability. For mixed production where different materials are machined, matching the insert geometry and feed rates to the workpiece will ensure the best compromise between performance and lifetime.

FAQ

What applications are suitable for this insert?
The insert is intended for drilling and reaming operations; the P4840C‑6R‑E67 WXP40 insert performs best where controlled chip evacuation and consistent hole quality are priorities.

Is the WXP40 grade coated or uncoated?
WXP40 is supplied as an uncoated carbide grade, offering economical performance and a focus on stable cutting behaviour.

Does the insert require a specific chipbreaker for certain materials?
The chipbreaker 6R‑E67 is designed to promote controlled chips; material-specific suitability should be checked against the product matrix for optimal parameter selection.

How does this insert support process security in production?
Its geometry and chip control provide predictable cutting behaviour, which contributes to repeatable hole quality and fewer interruptions during batch machining.

Can this insert be used in standard drilling toolholders?
Yes, the indexable design is compatible with common drilling and reaming tool assemblies, but toolholder and clamping specifications must match the insert designation.
