A portable drill system comprising:
- a drill handpiece comprising a first end, a second end, a drill bit-spindle assembly, a drill bit locking assembly, a motor, and a motor housing,
- wherein said drill bit-spindle assembly comprises a drill bit holder, a spindle assembly, and a motor shaft receiver,
- wherein said drill bit locking assembly is adapted for locking a drill bit to said drill handpiece,
- wherein said motor housing comprises a first end, a second end, and a body extending between said first end and said second end of said motor housing,
- wherein said first end of said motor housing engages with a drill bit lock cap of said drill bit locking assembly,
- wherein said motor shaft receiver is rotationally coupled to said drill bit holder such that when a motor shaft of said motor rotates, said drill bit holder also rotates at same speed and along same axis as that of said motor shaft;
- and
- a control device comprising a housing, a control printed circuit board (PCB), a drill handpiece connector terminal, and a motor speed control element,
- wherein said motor speed control element is adjustable by the user to adjust performance or working speed of said drill handpiece, and
- wherein said control PCB comprises a battery charging circuit and a direct current (DC) motor driving circuitry.
