Review on 🛠️ Enhance Your DIY Projects with the Hilitchi Plastic Drilling Hollow Wall Assortment by Marc Zitnik

I ended up using the smaller of the two sizes. The material they are constructed of is not strong enough to drill or screw into drywall. The tip breaks trying so I tried drilling a pilot hole. The threads do not have time to gain a foothold in the wall and simply make a big hole in it. Due to damage I had to resort to snap-on screws. They are made of very soft plastic.
