SDHT09T308-G88 WXN15 milling indexable insert by Walter Tools — square 90°, 15° lead angle

The SDHT09T308-G88 WXN15 is a square milling indexable insert designed for high‑quality machining of non‑ferrous metals, offering a 15° free angle and controlled chip formation in a compact T3 thickness.

• Square 90° geometry for versatile milling
• Sharp uncoated grade WXN15 for NE‑metals
• Chipbreaker G88 for optimised chip control
• 0.8 mm corner radius for consistent edge life

Consistent, sharp cutting performance for non‑ferrous machining

The insert is based on an uncoated carbide grade specifically formulated as WXN15 for non‑ferrous materials. This grade provides exceptionally sharp cutting edges and a low tendency for material adhesion, which reduces built‑up edge and improves surface quality when machining aluminium, copper and brass. The combination of a precise 15° free angle and a 0.8 mm corner radius helps maintain a predictable cutting geometry, translating into stable tool life and repeatable results in production runs.

Geometry and chip control that simplify process setup

The square 90° shape delivers four usable cutting edges per insert and supports a range of radial engagement angles. The integrated chipbreaker G88 promotes controlled chip segmentation with soft, continuous materials, reducing the risk of long, entangling chips and enabling higher feed rates. For workshop technicians and process engineers, these features mean fewer interruptions, easier chip evacuation and more consistent cycle times during milling operations.

Technical advantages translated into economic benefits

Using this indexable insert in a compatible milling cutter supports efficient material removal with low rework rates. The sharp, uncoated WXN15 grade is optimised for adhesion‑prone non‑ferrous alloys, which can lower the need for frequent edge dressing or premature replacement. In practical terms, this can improve overall process productivity and contribute to lower unit costs over extended production periods while keeping setup and handling straightforward.

Application guidance and compatibility notes

The insert is part of the Walter N‑grade system, intended for NE‑metal machining according to ISO group N. Its T3 plate thickness and compact format suit smaller diameters and shoulder or profile milling where tool stiffness and chip control are important. When selecting cutter bodies and clamping systems, ensure compatibility with the SDHT09T308‑style pocket and follow the machine‑specific recommendations for speeds and feeds with non‑ferrous materials to maximise performance.

FAQ

What materials is this insert best suited for?
The SDHT09T308-G88 WXN15 insert is optimised for non‑ferrous metals such as aluminium, copper and brass, following the ISO group N designation for NE‑metals.

Is the cutting grade coated or uncoated?
The cutting grade WXN15 used in this indexable insert is uncoated carbide, chosen for its sharp edge and low tendency for material adhesion when machining soft, ductile alloys.

How does the chipbreaker G88 affect milling of soft alloys?
Chipbreaker G88 promotes controlled chip segmentation and evacuation in soft materials, reducing long stringy chips and improving process stability with the SDHT09T308-G88 WXN15 insert.

What does the 15° free angle mean for cutting forces?
A 15° free angle reduces rubbing at the tool flank and supports smoother entry into soft materials, helping to lower cutting forces and limit heat generation during operations with this insert.

Can this insert be used for profile and shoulder milling?
Yes; the square 90° geometry and 0.8 mm corner radius make the insert suitable for shoulder and profile milling where multiple indexable edges and reliable corner life are required.
