B級品 – 1/2インチ トリプルフルート コンプレッションチップブレーカー (1/2インチ シャンク) 540-CM500CB-3FL

The triple flute geometry is doing exactly what I hoped—clean edges on both sides of the plywood with zero tear-out, even on the climb cut. You can tell it's a factory second only if you stare at the finish, but the cut quality makes that irrelevant.

I’ve used it for a few test cuts on plywood and the triple flute design leaves a surprisingly clean edge with zero tear-out, even at full depth. The chipbreaker really does its job—no clogging or burning halfway through. Only thing is the finish has a slight scuff, but for a factory second it’s cut

The shank seated perfectly in my router collet with no wobble, and the triple flute design left a cleaner edge than I expected for a factory second. Sure, the finish has a few cosmetic marks, but at this price it’s a steal for the cut quality.
