P2840S-1N-E67 WK40 Bohr-/Aufbohrwendeschneidplatte, uncoated carbide, 1N‑E67 chipbreaker — Walter Tools

The P2840S-1N-E67 WK40 is an indexable drilling and bore-enlarging insert intended for productive metalcutting tasks where an economical, uncoated carbide grade and controlled chip formation are required.

• Uncoated carbide for broad workpiece range
• 1N‑E67 chipbreaker for stable chip control
• Economical Walter grade WK40 for daily use
• Compatible with standard drilling toolholders

Predictable chip formation for smoother production

The combination of the 1N‑E67 chipbreaker and the WK40 uncoated carbide class delivers stable chip behaviour, which reduces interruptions and enables a steadier production flow. The chip geometry is designed to break and evacuate reliably under typical drilling and boring conditions, aiding process stability. As a result, cycle times become more consistent and the likelihood of tool-related rejects is reduced, supporting predictable shop-floor performance.

Robust material properties and grade guidance

The insert is manufactured from an uncoated cemented carbide grade from the Walter open series, offering a balance between wear resistance and economy. Uncoated carbide provides direct substrate toughness without surface coatings, which can be advantageous for certain cutting conditions and tool regrinding. Material suitability should be determined against the specific product matrix for the WK40 grade to ensure optimal selection for the intended workpiece materials.

Practical integration and operational advantages

As an indexable insert designed for drilling and bore enlargement, the P2840S geometry allows simple replacement and inventory handling, reducing downtime for tool changes. The insert integrates with standard drilling-holder systems and supports consistent repeatability across assemblies. Choosing a Walter open-grade insert like this one assists in stock rationalisation and cost control while maintaining reliable cutting performance for everyday workshop requirements.
