SNHX1205ZNN-K88 WXN15 — Indexable milling insert for non‑ferrous metals | Walter Tools

The SNHX1205ZNN-K88 WXN15 is an indexable milling insert designed for productive machining of non‑ferrous metals with a sharp, uncoated carbide grade and a K88 chipbreaker.

• Sharp uncoated carbide grade WXN15
• Square 90° geometry for strong edges
• K88 chipbreaker for controlled chips
• Negative rake 0° for stable cutting

High‑performance grade for non‑ferrous alloys

The insert uses an uncoated carbide grade optimised for NE‑metals, making it particularly suitable for aluminium, copper and messings (brass). The specified WXN15 composition delivers a sharp cutting edge that reduces material adhesion and helps to avoid built‑up edge, which is a common issue when machining soft, gummy alloys. This results in a more consistent surface quality and fewer interruptions for rework, supporting continuous production cycles and efficient cycle times.

Geometry and chip control that improve process stability

A square 90° plate form provides a robust cutting edge and multi‑edge indexing, while the integrated K88 chipbreaker shapes chips to avoid entanglement in the cutter and to ensure reliable evacuation. The negative rake 0° adds edge strength for interrupted cuts and offers predictable cutting forces, which simplifies fixture and toolholder choice. Together these features reduce vibration and support repeatable tool life, benefiting shops that prioritise throughput and process security.

Application benefits and machinability for workshop use

Designed for sharp, uncoated use, this insert is especially effective in high‑feed and finishing passes on softer metals where low cutting forces and minimal smear are required. The combination of the grade and chipbreaker promotes consistent surface finish without relying on surface coatings, which can be advantageous for operations that demand economical inserts with clear regrinding or disposal strategies. The insert’s profile supports precise dimensional results and a reduced need for secondary finishing.

Integration into existing tooling and recommended approach

The insert suits milling cutters and tool holders compatible with the SNHX geometry; selecting holders that maintain rigid clamping and proper coolant or air blow‑off will further enhance chip evacuation. For process setup, start with conservative feed values and increase incrementally while monitoring chip shape and surface output. The design supports shops seeking enhanced precision and elevated productivity in non‑ferrous machining applications; technical consultations are available to align cutting data with specific machines and workpiece conditions.
