Genuine DeWalt N016342 — Spanner Wrench: a compact, metal pin-style spanner designed to engage the blade/flange nut on compatible DeWalt cutting tools so you can loosen and re‑seat the flange safely and accurately.

This tool is listed under DeWalt part number N016342 for several tile‑cutters and cutters — for example the DW860 series (DW860 / DW860B / DW860BB2) and related DWC860W models — and appears in official parts diagrams as the spare spanner for those machines.

Use it to release or tighten the arbor/flange as shown in DeWalt service instructions (the same style of spanner is the tool DeWalt references for blade removal), and keep it with your toolbox so you have the correct tool when you need it. This is one of the handy genuine DeWalt spare parts to replace a lost or worn wrench and restore proper maintenance access to the tool.
