MPHT120408-G88 WXN15 milling indexable insert, G88 chipbreaker, 11° clearance – Walter Tools

The MPHT120408-G88 WXN15 is a milling insert designed for precise and productive machining of non‑ferrous metals, offering a sharp, uncoated carbide grade and a geometry tuned for aluminium, copper and brass applications

• Sharp uncoated carbide for clean cuts
• Optimised G88 chipbreaker for reliable chip control
• 11° clearance angle for reduced rubbing
• 0.8 mm corner radius for fine surface finishing

Stable chip control for higher throughput

The proven G88 chipbreaker geometry promotes controlled chip formation and evacuation when machining softer metals, which reduces interruptions and minimises rework. By converting irregular swarf into predictable fragments, the insert supports continuous cutting at higher feed rates and contributes to lower cycle times. The result is measurable process reliability and fewer machine downtimes thanks to more consistent swarf behaviour during long runs.

Sharp, uncoated carbide for burr‑free results in non‑ferrous metals

The WXN15 uncoated carbide grade is optimised for non‑ferrous workpieces, producing a very sharp cutting edge that lowers cutting forces and reduces the tendency for material to stick to the tool. For aluminium, copper and brass, this means cleaner edges, reduced built‑up edge and improved dimensional stability. The 0.8 mm corner radius and 11° clearance angle combine to deliver fine surface finishes without compromising edge strength.

Predictable integration into existing milling processes

Belonging to the Walter N‑Sortensystem, the insert offers standardised geometry and a reliable tolerance class H for repeatable positioning and reproducible results. The compact geometry (12 mm size, 4 mm thickness) allows straightforward retrofitting into common milling cutters, enabling economical tool stocking and rapid changeover. For production environments the combination of consistent tolerances and robust chip control translates into simplified process planning and reduced machining variation.

FAQ

What materials is this insert intended for?
The MPHT120408-G88 WXN15 insert is intended for non‑ferrous metals, specifically aluminium, copper and brass, using the N‑designation for appropriate workpiece groups.

Is the insert coated or uncoated?
This Walter Tools insert uses an uncoated carbide grade (WXN15), chosen for sharp cutting performance in soft, non‑ferrous materials.

How does the G88 chipbreaker affect machining?
The G88 chipbreaker promotes controlled chip segmentation and evacuation, improving process stability and reducing the risk of built‑up edge during prolonged cutting.

What are the key dimensions to check for tool compatibility?
Key dimensions are 12 mm plate size and 4 mm thickness, with a 0.8 mm corner radius and 11° clearance angle; these determine fit and finish in compatible milling cutters.

Does this insert offer consistent positioning for repeatability?
Yes, the insert comes with tolerance class H as part of the Walter N‑Sortensystem, supporting repeatable seating and reproducible machining results.
