Infinity Tools 1/4 英吋柄直線銑刀附頂部軸承

Finally a bit that stays true on deep passes—the bearing above the cutter keeps the pattern flush without burning the wood. Cuts clean through maple ply with zero tear-out.

The bearing sits above the cutter just like the description says, and it tracked my pattern perfectly on a cabinet trim job without any burning or chatter. I've used cheaper flush-trim bits before, but this one left an edge clean enough that I didn't even need to sand it.

Took a chance on this bit for a template routing job, and the top bearing design made flush-trimming effortless. The bearing spins smoothly, and the cut comes out clean without any burn marks.
