工廠次級品 – 雷射瑕疵 – 1/16″ 長伸縮下切螺旋刀 (1/4″ 柄徑)

I was worried about the blemish affecting performance, but after using it for a few test cuts, the 1/4-inch shank provides rock-solid stability and the down-cut spiral leaves clean edges. It’s a great value for a bit that works just like a first-quality one.

The laser blemish is barely visible once it's in the collet, and the 1/4-inch shank fits my router perfectly. The 1/16-inch reach let me get into a tight slot without any chatter, honestly can't tell this was a factory second.

I’ve been putting this bit through some tight pocket cuts and the 1/4-inch shank holds perfectly steady, no chatter at all. The laser blemish is just a tiny spot on the finish, doesn’t touch the cutting edge or the reach. For a factory second, it’s performing like a first run.
