They must have redesigned this. People were saying that the metal tips on the rods screwed into a plastic brush attachment. The one I received was metal to metal and has an allen screw to tighten it down , wrench included, in case you should accidentally put the drill in reverse. This is a quality tool. I have no complaints. Plus if you should somehow get the attachment stuck in the vent ,the instruction manual has another attachment you can order to retrieve it. I had no problems but I also have a vent that goes straight up through the roof. I had to but the extra rods everything is copasetic.
