Overview

The Hitachi 323342 Straight Guide Assembly is a dedicated routing accessory designed for use with the Hitachi KM12SC router. It serves a simple but essential function: providing a stable, adjustable reference edge that guides the router along a workpiece for straight, consistent cuts at a set distance from the material's edge. This is particularly useful for tasks like dado cuts, edge profiling, and any routing operation where repeatability and precision matter.

As a genuine Hitachi accessory, the 323342 is engineered to mount securely to the KM12SC router base without play or wobble, which directly translates to cleaner, more accurate results. The setup process is intuitive — adjust the guide to your desired offset, lock it in place, and begin routing. While it is limited to straight-line work and only fits the KM12SC model, it fulfills its intended purpose reliably and is an essential addition for KM12SC owners who regularly perform edge-guided routing tasks.
