We use an electric drill for making a hole and DIY furniture.
This is very easy to use and used to be, but there are many problems, like scraps, dust or another.
This can harm your health. So you have to clean this very well, after you use this.
Our idea can help you for cleaning. Whenever you work with this, you can see the small fragments. But if you use our idea, you cannot see them. Because this can gather them in the dust blocker bottle while you work.
