A pressure-sensitive grip for a dental hand drill for providing continuous control of the speed thereof. The pressure-sensitive material preferably comprises a strain gage sensing element positioned along the body portion of the dental tool which is normally hand held by the operator. In a fluid-driven dental tool, the strain gage is coupled through a control network which provides an electrical signal to control a proportional valve in the fluid supply line to the drill.
