SDHT120408-G88 WK10 — Fräswendeschneidplatte (square 12 mm, 0.8 mm radius) by Walter Tools

The SDHT120408-G88 WK10 is a square milling indexable insert for versatile finishing and semi-finishing operations, engineered for stable chip formation and economical machining.

• Uncoated cemented carbide WK10 grade
• 12 mm square with 0.8 mm corner radius
• 15° relief angle for versatile engagement
• G88 chipbreaker for controlled chips

Stable results from a robust carbide grade

The insert uses the WK10 uncoated cemented carbide grade, designed for broad applicability where an economical, reliable cutting edge is required. The choice of an uncoated grade delivers consistent performance across varied tasks and supports predictable wear progression. For production environments looking to balance cost and tool life, the WK10 grade enables dependable cutting behaviour and stable chip formation, reducing downtime for tool changes and simplifying process planning.

Precision geometry for repeatable finishes

With a 12 mm square form and a 0.8 mm corner radius, the geometry supports accurate shoulder milling and controlled step-downs. The 15° relief angle reduces cutting forces at engagement while preserving edge strength, which helps maintain surface integrity during finishing passes. The square 90° shape offers multiple indexed edges, allowing economical reuse of the insert when edges are rotated; this provides a clear advantage in workshops where repeatability and tool rotation strategy matter.

Controlled chips and improved process security

The G88 chipbreaker is designed to produce small, manageable chips under typical milling parameters, which improves evacuation and reduces the risk of re-cutting. Better chip control contributes directly to process security, surface quality and machine uptime. The insert’s configuration supports stable cutting in a variety of setups; however, final workpiece suitability should be verified against the manufacturer’s product matrix to ensure optimal parameter selection and coolant strategy for each material group.

Practical integration and application guidance

The insert is supplied in the ISO designation SDHT120408-G88 WK10 and carries a thickness code of 04 and tolerance class H. Its series designation indicates an open Walter carbide family; this aids selection for users who require traceable material and production standards. If material compatibility or cutting data are unclear, Metav Werkzeuge’s technical advisors can help determine optimal cutting speeds and feeds or suggest an alternative grade or geometry for specific tasks. For fast clarification, provide the ISO designation or SKU when enquiring.

FAQ

What materials is this insert suited for?
The SDHT120408-G88 WK10 is based on an uncoated cemented carbide grade; material suitability must be checked in the product matrix to confirm optimal application for specific alloys or material conditions.

How does the G88 chipbreaker affect machining?
The G88 chipbreaker promotes short, controllable chips, improving evacuation and surface finish; this reduces the likelihood of recutting and supports longer uninterrupted cycles with the SDHT120408-G88 WK10 insert.

How many usable cutting edges does the square insert provide?
The square 90° form typically offers four indexable cutting edges, allowing economical rotation of the insert to extend overall tool life.
