š Sure. First, using a spiral flush trim (especially down-cut or compression style) is tip number one, as they inherently reduce tear-out by the way they cut:contentReference[oaicite:50]{index=50}. But regardless of bit type: **pay attention to grain direction**. If you route ādownhillā with the grain (meaning the router is cutting in a direction that doesnāt lift the grain), youāll get a cleaner result. Sometimes that means climb-cutting small sections ā which you should do with caution and light passes ā but it can spare tear-out on gnarly grain. Another tip: take a shallow pass first. You can trim nearly flush leaving a very small amount, then do a final skim cut ā less material = less tear-out risk. Secure your template and work tightly so nothing chatters. And of course, make sure your bit is sharp. A dull flush trim is a recipe for chatter and tear-out. If you follow the grain and use the right bit, youāll get a nice clean edge in most woods.
