HOLE CUTTING TOOL

WIPO Patent Application WO2004110708

A3

A hole cutting tool (10) configured for cutting an accurately located and precisely shaped hole in a surface, such as a wall (W) of a finished residential or commercial building is disclosed. The tool (10) provides a frame assembly (12) which is self-adhering, to the surface (W) and carries removable templates (14, 146-152) for handsfree use in cutting an accurately located and precisely shaped hole. The unique frame assembly (12) provides multiple selectable, pneumatically isolated suction chambers (50,52) that enable the self-adhesion function even when the frame assembly (12) is placed over existing holes in the surface (W). The suction chambers (50,52) are formed in part by a unique corrugated gasket (56) that enables the frame assembly (12) to self-adhere to porous surfaces. The removable template (14) enables dust particles created during the cutting process to be simultaneously vacuumed away regardless of the orientation of the template (14) relative to the frame assembly (12).
