High speed hand drill with swiveling pressure foot and integrated vacuum pickup and coolant delivery duct

A high speed handheld power drill, comprising:

• a housing having a motor disposed therein;
• a chuck disposed in the housing and rotationally driven by the motor;
• an elongated drill bit having an inner end coupled in the chuck for rotation about a long axis of the bit;
• an elongated pressure foot mounted on the housing for coaxial rotation about the drill bit and through a plurality of selectable angular positions relative to the housing;
• a drill guide slidably disposed within the pressure foot at an outer end thereof and biased for coaxial sliding movement between the drill bit and the pressure foot;
• a vacuum cuttings pickup and coolant fluid delivery tool coupled to the drill guide and arranged to deliver a liquid coolant to the drill bit and to remove drill cuttings and coolant fluid vapor therefrom during drilling;
• and,
• a coolant fluid reservoir coupled to the drill motor housing and adapted to deliver selectably metered amounts of pressurized coolant fluid to the cuttings pickup and coolant delivery tool during drilling.
