Power saws and power drills are commonly used equipment. Power saws are used to remove or shape bone. The blades of an oscillating saw move back and forth in a swinging motion, whereas the blades of a reciprocating saw move back and forth in a straight line. The power source may be a battery pack, compressed nitrogen, or electricity. When setting up the saw, it is important to attach the power cord to the saw before attaching it to the power source.

Power drills are used to make holes for the insertion of wires or screws or for reaming long bones. Some drill bits are attached by a chuck that requires a key, whereas others may be tightened with a keyless chuck. Drill bits may be cannulated so wires can be used as guides for the drill. Power drills include the Maxi driver, Stryker Mini, and MicroAire.
