SDHT09T304-G88 WXN15 milling indexable insert — uncoated carbide, 15° clearance | Walter Tools

The SDHT09T304-G88 WXN15 is a square 90° milling indexable insert designed for efficient, sharp-edge machining of non‑ferrous metals such as aluminium and brass

• Uncoated carbide grade WXN15 for non‑ferrous metals
• Square 90° geometry with 0.4 mm corner radius
• 15° clearance angle for sharp-edge cutting
• G88 chipbreaker for reduced material adhesion

Precise grade and intended application for non‑ferrous work

The insert is manufactured in the Walter N-grade philosophy and uses the uncoated WXN15 cemented carbide, a configuration optimised for machining non‑ferrous metals. The combination of an uncoated, very sharp cutting edge and a dedicated chip geometry reduces the risk of material smearing on the cutting edge—especially important for aluminium and brass. This results in stable cutting conditions, improved surface quality and fewer interruptions for edge cleaning. The designation and series data indicate suitability for friction‑sensitive materials rather than general‑purpose steel machining.

Controlled chip formation and process stability with the G88 breaker

The integrated G88 chipbreaker is designed to split and evacuate chips reliably in soft and ductile substrates. In practice, a chipbreaker reduces built‑up edge formation and prevents long stringy chips from wrapping the tool, which increases operational uptime. For workshops aiming at predictable cycle times, the chip geometry translates into consistent chip shape and machine load. The term chipbreaker here refers to a profiled land on the insert face that guides and segments material flow, improving both tool life and operator safety during high feed operations.

Geometry and tolerances that support reproducible production

The square 90° geometry with a 0.4 mm corner radius and a 15° clearance angle delivers a balance between strength and sharpness: the corner radius provides a defined edge for finishing passes while the clearance angle reduces rubbing on the flank. The plate thickness T3 and tolerance class H ensure repeatable seating in standard toolholders and reliable indexing. These dimensional and tolerance details help maintain part accuracy across batches and simplify tool programme validation in CNC setups. The result is a predictable, high‑quality finish with reduced rework.

FAQ

What materials is this insert best suited for?
The SDHT09T304-G88 WXN15 insert is optimised for non‑ferrous metals such as aluminium, copper alloys and brass; the uncoated WXN15 grade and G88 chipbreaker aim to prevent material adhesion.

How does the G88 chipbreaker affect machining?
The G88 chipbreaker on the SDHT09T304-G88 insert promotes segmented chips and stable evacuation, which reduces built‑up edge and improves surface finish during milling of ductile materials.

Can this insert be used for finishing passes?
Yes, the combination of 0.4 mm corner radius and 15° clearance angle makes the insert suitable for finishing and light‑interrupted cuts in non‑ferrous applications, offering a good balance between sharpness and edge strength.

Is the insert compatible with standard square indexable holders?
The SDHT09T304-G88 WXN15 follows common square 90° geometry dimensions and the T3 plate thickness, enabling use in holders designed for that designation when clamped according to the holder manufacturer’s specifications.

What does the WXN15 grade indicate?
WXN15 denotes an uncoated cemented carbide grade developed for sharp‑edge performance on non‑ferrous materials; the Walter N‑grade approach focuses on low adhesion and consistent chip control.
