A technician must drill holes at multiple heights on a construction site with limited access to power outlets. Which portable drilling solution is most suitable?
Using a battery-operated cordless drill
The situation calls for drilling holes at several different heights while moving around a construction site where mains power outlets are scarce.
The key requirements are full portability and freedom from any fixed power connection or heavy mounting, so the tool must carry its own energy source.
A battery-operated cordless drill meets both needs: its rechargeable pack lets it run anywhere on the site, and it is light enough to raise and use at any working height.
Because there is no trailing cable, the worker can climb, move between locations, and drill overhead or at odd angles without hunting for a socket.
A heavy stationary drill press (option 2) and a corded electric bench drill (option 3) are fixed to a bench and tied to a mains supply, so they cannot follow the worker to varied heights.
A pneumatic drilling machine (option 4) needs a compressor and air hose, which again demands a bulky setup and power that the site cannot readily provide.
Hence, the answer is Using a battery-operated cordless drill.
