Dewalt-DWV2759 5 piece Dust Extractor Accessory Kit

I have had this set for over a year. I use it with DWV010 dust vacuum in woodshop/garage. The metal tubes are lined with plastic so they are electrically isolated. The tube connections do not grip well and frequently come loose during use. The quick attach coupling with the hose also frequently unlocks and comes loose during use. You cannot safely use the tubes alone as the end to quickly get in a tight spot or the sharp metal edge will scratch whatever it touches. The metal tube is strong but does easily dent and deform. If you step on it at all it will be very deformed and if at the end of the tube it would not be usable. I have not yet found another tube system that will fit on the hose that came with the DWV 010 but am still looking. Plastic tubing is the better material for these tubes in a shop setting.
