SPHT060304-G88 WXN15 – Square 90° milling insert with G88 chipbreaker for non‑ferrous metals (Walter Tools)

A SPHT060304-G88 WXN15 indexable milling insert engineered for high‑productivity machining of aluminium, brass and similar non‑ferrous alloys.

• Square 90° insert with strong cutting edge
• Sharp uncoated carbide grade WXN15
• Corner radius 0.4 mm for edge strength
• Optimised chip control with G88 breaker

Consistent productivity when machining non‑ferrous metals

The WXN15 grade provides an uncoated carbide geometry tailored to non‑ferrous materials, delivering a sharp cutting edge that reduces built‑up edge and stickiness when milling aluminium and brass. Combined with the G88 chipbreaker, the insert offers stable chip formation and evacuation, which improves cycle times and reduces stoppages. This results in a measurable increase in process efficiency and fewer interruptions on the shop floor, supporting higher throughput and predictable output.

Precision geometry that improves surface quality and tool life

The square 90° form with a corner radius 0.4 mm and an 11° clearance angle balances cutting strength and surface finish. The modest corner radius enhances edge resilience against impact while still allowing fine surface finishes, and the clearance angle minimises rubbing on the workpiece. The G88 chipbreaker is designed to break and guide chips away from the cutting zone in sticky materials, lowering the risk of rework and enabling consistent part quality with fewer manual interventions.

Reliable fitment and repeatable results for production use

Belonging to the Walter N‑series, this insert is manufactured to tolerance class H, ensuring repeatable seating and indexing in compatible toolholders. The insert size 06 and thickness code 03 are industry codes for quick identification during tool management and reordering. The robust design supports straightforward integration into existing milling systems and helps maintain steady production characteristics batch after batch, reducing setup variance and improving overall process control.

FAQ

Which materials is this insert suitable for? The SPHT060304-G88 WXN15 insert from Walter Tools is intended for non‑ferrous metals (ISO group N), such as aluminium, copper and brass, where sharp, uncoated carbide edges prevent material adhesion.

Is the WXN15 grade coated? WXN15 is an uncoated carbide grade; the SPHT060304-G88 WXN15 relies on geometry and a sharp edge rather than a coating to perform in sticky, non‑ferrous applications.

How does the G88 chipbreaker affect machining? The G88 chipbreaker promotes short, controlled chips and guides them away from the cutting zone, which reduces surface contamination and lowers the likelihood of chip recontact during milling of soft metals.

Why is the 0.4 mm corner radius important? A corner radius of 0.4 mm increases edge strength compared with a sharper radius, helping to resist edge chipping while still supporting good surface finish in non‑ferrous milling operations.

What benefit does the 11° clearance angle provide? The 11° clearance angle reduces friction between the insert flank and the workpiece, decreasing heat build‑up and improving dimensional stability during continuous milling passes.
