Useful device for drilling walls and not to scatter everything with drill dust.

Good quality product but I did not like the functionality although I chose the smaller one with a normal drill bit does not work and the powder should be discarded after each use being this uncomfortable with several perforations. The idea can be improved.

Producto de buena calidad pero no me gustó la funcionabilidad pese a que escogí el más pequeño con una broca normal no sirve y el polvo debe ser desechado después de cada uso siendo esto incómodo con varias perforaciones. La idea se puede mejorar.
