As other reviews have mentioned this nozzle does a great job with clean tongues. I blame its one star for the poor packaging. It comes in a collapsible plastic package that has separate compartments for the drill bit and each bearing, with molded in 'catches' to keep the package closed while keeping the parts isolated from each other. Some of the latches on my backpack broke in transit and all the bearings migrated into the main compartment along with the racquet, where they all bounced around together. Even with working closures, the packaging is bulky and flimsy and not suitable for repeated use. I don't have proper storage for my router bits yet so I just use the packaging they come in and so far everything has been fine. I consider Freud to be a premium brand, so I didn't expect something like this even in the mundane packaging space.
