OPHN050412-A57 WSN10 — Milling indexable insert, A57 chipbreaker, octagonal form — Walter Tools

The OPHN050412-A57 WSN10 is a coated carbide indexable insert designed for general milling applications where dependable chip control and reproducible cutting performance are required

• Coated carbide grade WSN10
• 11° clearance angle for secure cutting
• A57 chipbreaker for reliable chip control
• Octagonal form with 1.2 mm corner radius

High-performance carbide grade for stable machining

The coated carbide grade WSN10 provides a balance of wear resistance and edge security that supports efficient machining cycles. Combined with the A57 chipbreaker, the insert helps to control fragments and evacuate chips consistently, which reduces process interruptions and improves cycle times. The octagonal form and 1.2 mm corner radius contribute to edge strength, helping to maintain surface quality over repeated indexing. These characteristics promote a dependable performance profile suited to series production and mixed-batch machining where repeatability matters.

Precision geometry that improves tool life and surface quality

The 11° clearance angle reduces rubbing between insert flank and workpiece, lowering friction and the thermal load on the cutting edge during milling passes. The design of the chipbreaker optimises chip formation for predictable evacuation, which results in fewer built-up edges and a more uniform finish. The insert’s geometry and tolerance class H support stable seat positioning and consistent cutting geometry in compatible tool holders. For materials and the exact cutting-parameter window, the material suitability is catalogue-dependent; please check the product matrix to match the insert variant to the intended workpiece material.

Practical benefits for production workflows

Using the OPHN050412-A57 WSN10 indexable insert can reduce downtime associated with poor chip control and unexpected wear, thanks to the combination of coated carbide, robust chipbreaking and a compact octagonal form. The insert’s configuration supports straightforward indexing and predictable tool-change intervals, helping to simplify process planning. While the insert is engineered for productive cutting, the final choice of grade and geometry should be aligned with the specific machining task and holder system to achieve the best balance of tool life and productivity.

FAQ

What materials is this insert suitable for?
Material suitability is catalogue-dependent; consult the product matrix to determine whether the OPHN050412-A57 WSN10 is specified for the intended workpiece material and application.

How does the A57 chipbreaker benefit milling operations?
The A57 chipbreaker on the OPHN050412-A57 WSN10 helps form and break chips predictably, improving evacuation and reducing the risk of built-up edge and tool damage during milling.

What does the tolerance class H indicate for the insert?
Tolerance class H signifies the manufacturing tolerance for seating and geometry; for critical applications, check that the tool holder and seat conform to the required tolerance for optimal stability.

Can the corner radius influence surface finish?
Yes, the 1.2 mm corner radius contributes to edge strength and helps achieve consistent surface quality while balancing cutting forces and edge life for milling passes.

Is the OPHN050412-A57 WSN10 suitable for high-volume production?
The coated carbide grade and chipbreaker design support repeatable performance, making the insert a practical option for production environments when matched to the correct holder and cutting parameters.
