Abstract
A drill including a drill spindle capable of driving a cutting tool in movement. The drill has at least one channel for distributing a lubricant to the cutting tool, a pump to supply the channel with lubricant and control element(s) for controlling the flow rate of the pump. Such a drill further has mechanical element(s) for determining at least one piece of information representing the torque exerted on the spindle along its axis during drilling. The control element(s) act on the flow rate of the pump as a function of the torque exerted on the spindle along its axis during drilling.
