1/4吋 下切螺旋齊平修邊銑刀（AstraHP塗層）

Using this on some tricky cherry edge-banding last night and the AstraHP coating really helped it glide through without gumming up. The finish was so smooth I barely needed any sanding before applying the next piece.

The AstraHP coating on this bit held up through a whole afternoon of trimming oak without any burn marks, and the down-cut spiral left a surface so clean I didn't need to sand before finishing. I've used cheaper bits that chattered on end grain, but this one stayed true the entire cut.

The down-cut spiral really does keep the top edge tear-out free—I ran it along some plywood and the finish came out buttery smooth without any chipping. It’s a great flush trim bit for the price, and the coating seems to hold up well after several passes.
