SPHT120408-G88 WK10 milling insert – Square 90°, r0.8, 11° (Walter Tools)

The SPHT120408-G88 WK10 is a square 90° milling indexable insert designed for stable general‑purpose milling and finishing where predictable chip formation and repeatable edge life are required.

• Square 90° insert for stable milling
• Corner radius r0.8 for controlled edge strength
• G88 chipbreaker for predictable chip formation
• Uncoated carbide grade WK10 for versatile use

Consistent cutting geometry for reliable production results

The square 90° geometry combined with a corner radius r0.8 delivers a robust cutting edge that supports consistent engagement and reduced edge chipping. The modest free cutting angle of 11° moderates cutting forces, helping to maintain process stability across a range of machining conditions. These geometric choices favour repeatability on medium‑duty milling operations and improve tool life by distributing contact stresses more evenly over the insert edge. The result is stable cutting behaviour and fewer interruptions in production.

Chip control that reduces rework and downtime

The integrated G88 chipbreaker is engineered to form short, controllable chips in many common materials, easing chip evacuation and reducing the risk of surface damage or tool interference. Predictable chip formation shortens cycle times by lowering the likelihood of manual chip clearing and limits the need for secondary finishing. For operations aiming at consistent part quality, the chipbreaker supports higher process confidence and contributes to overall machining efficiency.

Material grade and series: what WK10 offers to workshops

Manufactured in the Walter Schneidstoffsorte series and specified as WK10 — an uncoated carbide grade — the insert represents a versatile baseline solution suitable for a broad matrix of workpiece materials (see product matrix for exact suitability). The uncoated construction simplifies regrinding and inspection and may be advantageous where coated grades are unnecessary or where welding/adhesion concerns arise. For applications where a balanced performance, ease of handling and reliable edge life are priorities, this insert provides an economical and predictable option.

FAQ

What materials is this insert suitable for?
The SPHT120408-G88 WK10 insert is specified in the Walter Schneidstoffsorte series; suitability depends on the product matrix, with the uncoated WK10 grade intended as a versatile baseline for a broad range of materials.

How does the G88 chipbreaker affect machining?
The G88 chipbreaker on this milling insert promotes short, controllable chips, improving chip evacuation and reducing risk of surface damage or entanglement during milling operations.

Can the insert be reground or reconditioned?
As an uncoated carbide grade, the WK10 insert is generally more straightforward to regrind than coated alternatives; however, reconditioning should follow manufacturer recommendations and assess remaining corner radius and tolerance class H.
