I am not sure if anyone has used one of these before, but I wanted to share with you how life saving this tool is. I have been doing up my house for a few months now and started off trying to catch the dust and brick debris using a hoover in one hand and drill in the other hand. As you can imagine it ended in me being very frustrated and dust on the floor. One day I had a friend helping me and he saw what I was doing and he recommended these type of drill and dust catcher and at first brought some cheap alternatives which literally shattered on first use. So I then decided to take the plunge and pay out for the proper dade and I have never looked back.
Anyway, I hope this helps someone out especially as I know it will save you loads of time cleaning up and save you from being frustrated.
