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

A vacuum template has a suction chamber on its back surface that adheres the template to the wall or other flat surface when a source of vacuum pressure attached to the template is turned on and the template has been placed by the worker in its desired position. Dust inlets adjacent a guidance hole in the template immediately suction away dust particles as the hole is being cut by a power tool or hand saw manipulated by the user. Interchangeable modules on the template provide for variations in hole size and shape.
