Multi-function ONE(1)Grip and Built-in LED
The ONE(1)GRIP stands at the core of the DOER System. By sliding the grip from the rear to the front of DOER tool head's installation grooves until a satisfying, audible *click* is heard, portable power tools with continuously variable operation speed are created after installing a battery pack. The ONE(1)GRIP has secondary controls that reverse direction in some tools, and act as a safety interlock in others.
