Abstract

A pressure pad for holding a drilling surface flat also accomplishes the dispersal of drill debris by directing air underneath the debris. The pad is designed and works as described in the following. The pressure pad 1 contains six air inlets 2 which serve to direct air for debris removal. The air inlets are connected to a vacuum manifold (not seen) which pulls air through the inlets. The angular configuration of the inlets creates a swirling motion within the drill chamber 3 which starts debris rotation. The swirling motion is in the same direction as the drill rotation. The rotational motion eventually throws the debris from the drill area.

Pressure Pad Air Directional Device

A pressure pad for holding a drilling surface flat also accomplishes the dispersal of drill debris by directing air underneath the debris. The pad is designed and works as described in the following. The pressure pad 1 contains six air inlets 2 which serve to direct air for debris removal. The air inlets are connected to a vacuum manifold (not seen) which pulls air through the inlets. The angular configuration of the inlets creates a swirling motion within the drill chamber 3 which starts debris rotation. The swirling motion is in the same direction as the drill rotation. The rotational motion eventually throws the debris from the drill area. As the drill enters the drilling surface, the debris exiting the drilled hole encounters the swirling upward motion induced by the vacuum and is then pulled away from the drill chamber of the pressure pad. The swirling airflow removes debris from not only the pressure pad but also the drilled surface to minimize clogging of the drill and the pressure pad.
