Dust free drill system

摘要

Hammer drills and similar devices have an ongoing dust and debris problem that is solved by a protector device covering the drill in a main body protector shielding a user from the materials. The protector device has an evacuation region on its underside with multi dimensional adapters for attaching hoses of varying sizes. Additionally, an insertable collapsible accordion cylinder assists in covering the debris falling from different size drills being used. A second embodiment has a circular saw dust protector attachment arranged as two half moons or ¼ moon and ¾ moon having a central cylinder at their respective tops that are to be held together with a mechanical latch.
