Infinity Tools PDJ-100 溝槽治具專用黃銅導軌

I always hated wobble in my dado cuts, but this brass guide sits perfectly flush against the jig and feels rock-solid during use. The cut quality on my first test board was noticeably cleaner than with my old steel template.

This thing is incredibly accurate—the ¾" brass guide runs smoothly without any binding, and my dados come out perfectly sized every time. Took maybe five minutes to set up on my router, and now I fly through joinery that used to take forever.

I was a little skeptical about dropping the money on a brass guide, but the ¾" template slot runs my router bit through the dado with zero slop. The precision is exactly what I needed for repeatable joints without measuring twice. This jig just feels solid and made my next shelving project fly by.
