Excellent depth of cut for a 1/8" diameter router. I use this on my CNC router and get very smooth ones Cuts with very little to no grain lift (aka fluff) when I'm cutting across the grain. Plunge requires a little care. Plunge cuts burn easily if the feed is too high, but good results are achieved with a gentle bevel and reduced feed. How any other drill even with good dust pick up will have 100% of the cutter width clogged with chips Down compression bits handle chips better but good luck finding 1/8" bits. I would give 5 stars if the cut was better.
