Toolholder having a movable coolant pipe

A toolholder comprising:

• a tool body rotatable around a central axis, the tool body having a tool body first end, a tool body second end, a coolant channel, a tool body passageway, and a chamber, the coolant channel extending through a portion of the tool body, the tool body passageway disposed on the tool body second end, the chamber extending from the tool body passageway toward the coolant channel;
• and
• a coolant pipe attached to the tool body, the coolant pipe disposed within the chamber and partially disposed within the tool body passageway, the coolant pipe having a coolant pipe first end, a coolant pipe second end, a coolant pipe first opening, a coolant pipe second opening, a coolant pipe passageway, and a coolant pipe portion, the coolant pipe first opening in fluid communication with the coolant channel, the coolant pipe passageway extending from the coolant pipe first opening to the coolant pipe second opening, the coolant pipe portion extending from the coolant pipe second end toward the coolant pipe first end, the coolant pipe movable between a resting position and a deflected position, in the resting position the coolant pipe portion disposed a first distance from the central axis and disposed on a coolant pipe first axis, in the deflected position the coolant pipe portion disposed a second distance from the central axis and disposed on coolant pipe second axis, the second distance greater than the first distance, the coolant pipe second axis different than the coolant pipe first axis.
