Abstract
A high speed handheld power drill includes a housing with a motor, a chuck rotationally driven by the motor, and a drill bit clamped in the chuck. A pressure foot is mounted on the housing for coaxial rotation about the drill bit and lockable in a selectable angular position relative to the housing. A drill guide is slidably disposed within the pressure foot at an outer end thereof and biased for coaxial sliding movement between the drill bit and pressure foot. A vacuum cuttings pickup and coolant fluid delivery tool is coupled to the drill guide and arranged to deliver coolant fluid to the drill bit and to remove drill cuttings and coolant fluid and vapor therefrom during drilling. A coolant fluid reservoir is coupled to the drill motor housing and adapted to deliver selectably metered amounts of coolant fluid to the cuttings pickup and coolant delivery tool during drilling.
