SDHT1204AZN-G88 WK10 milling insert, square 90° with 15° relief – Walter Tools

The SDHT1204AZN-G88 WK10 is a square milling insert intended for general milling applications, combining a G88 chipbreaker with the WK10 uncoated carbide grade for consistent chip formation and stable cutting performance.

• WK10 uncoated carbide grade
• Square 90° form for robust milling
• G88 chipbreaker for controlled chips
• 15° relief angle for secure cutting

Stable chip control for uninterrupted production

The geometry and chipbreaker of this indexable insert are designed to promote predictable chip formation and minimise interruptions. The combination of the G88 chipbreaker with a square geometry yields short, manageable chips under many milling conditions, which reduces the risk of re-cutting and improves machine uptime. In practice, this means fewer manual interventions at the machine and a smoother process flow, supporting higher overall throughput and more consistent cycle times.

Material grade explained for pragmatic process decisions

The insert is supplied in the WK10 uncoated carbide grade, which is an economical option when a robust cutting edge and cost-effective performance are required. As an uncoated grade, WK10 provides straightforward tool behaviour at moderate cutting speeds and can be preferable where coating sensitivity is an issue. Process engineers should refer to the product matrix to confirm suitability for specific workpiece materials and cutting parameters; this step ensures the chosen grade aligns with the required productivity and component quality targets.

Geometry and handling that support repeatable accuracy

With a square 90° plate form and a 15° relief angle, the insert offers a stable cutting edge and clear seating orientation in indexable toolholders. The thickness code and size code indicate the standard insert proportions for secure clamping and predictable strength at the cutting edge. The tolerance class H contributes to consistent mounting accuracy and repeatability across multiple indexings, which is important for maintaining surface quality and dimensional stability during serial production. Overall, the geometry supports robust face and peripheral milling where a firm edge and reliable chip evacuation are priorities.

FAQ

What materials is this insert intended for?
The SDHT1204AZN-G88 WK10 milling insert is supplied in the WK10 uncoated carbide grade; suitability for specific materials should be verified against the product matrix before selection.

Is the chipbreaker suitable for heavy chip loads?
The G88 chipbreaker is designed for controlled chips and improved evacuation, contributing to stable performance under many milling conditions with consistent chip removal.

Can these inserts be indexed to extend tool life?
Yes, the square 90° form and tolerance class H support safe indexing and repeatable seating, which helps to maximise usable edges and reduce tooling costs.

Does the insert have a coating?
This product is specified in the WK10 uncoated carbide grade and does not include a surface coating as delivered.

How does the 15° relief angle affect cutting performance?
A 15° relief angle provides a compromise between edge strength and clearance, offering secure cutting action while reducing rubbing at the flank face for improved surface finish.
