SPHT09T308-G88 WXN15 — milling indexable insert, square 90°, 11° clearance (Walter Tools)

The SPHT09T308-G88 WXN15 is a square 90° milling indexable insert designed for precise and productive machining of non‑ferrous metals such as aluminium, copper and brass.

• Sharp uncoated carbide grade WXN15 for NE‑metals
• 11° clearance for reduced cutting forces
• 0.8 mm corner radius for predictable edge strength
• G88 chipbreaker for reliable chip control in non‑ferrous

Consistent, burr‑free finishes on non‑ferrous alloys

The combination of a sharp uncoated carbide cutting edge and the WXN15 grade is engineered for machining NE‑metals where low adhesion and clean chips are essential. A deliberately sharp geometry reduces the tendency for material to stick to the cutting edge, which limits built‑up edge and improves surface quality. For production environments that value consistent part finish, this insert provides reproducible results when used with appropriate feeds and speeds for softer, ductile materials.

Geometry that balances low cutting forces with edge stability

The insert’s 11° clearance lowers rubbing at the flank and reduces cutting forces, which helps maintain tool life and lowers power draw on smaller spindles. The 0.8 mm corner radius offers a defined edge profile that resists premature chipping while still permitting fine surface finishes; a larger radius would add strength but could increase cutting forces. The square 90° form supplies versatile indexability and predictable toolpath results for shoulder and slot milling where controlled engagement is required.

Predictable chip formation and higher machining productivity

Equipped with a G88 chipbreaker, the insert directs chips into short, controllable segments that evacuate efficiently from the cutting zone. Effective chip control is particularly beneficial for aluminium and similar alloys, preventing long stringing chips and reducing rework. Reliable chip formation supports steady cycle times and can contribute to higher overall productivity by reducing tool‑related interruptions and the risk of surface blemishes.

System compatibility and shop‑floor integration

Produced for the Walter N‑series, this insert matches Walter tool systems and retains consistency within established tooling families. Key attributes such as tolerance H and execution T indicate stable manufacturing quality and repeatable geometry. Measurable dimensions—plate size 09 and thickness T3—allow planners to confirm fitment to compatible cutters. If a clarification of holder compatibility or cutting parameters is required, Metav Werkzeuge provides technical consultation to support integration into existing processes.

FAQ

What materials is this insert intended for?
The SPHT09T308-G88 WXN15 insert from Walter Tools is intended for non‑ferrous metals such as aluminium, copper and brass, as indicated by the WXN15 grade.

How does the G88 chipbreaker improve machining?
The G88 chipbreaker shapes chips into short, controllable segments, improving evacuation and reducing the risk of long stringing chips when machining soft, ductile materials with the Walter Tools milling indexable insert.

What does the 11° clearance angle mean for cutting performance?
An 11° clearance reduces flank contact and cutting forces, which helps lower tool wear and provides smoother cutting behaviour for the SPHT09T308-G88 WXN15 insert.
