For deep hole drills, when drilling deep holes, it is necessary to discharge a large amount of chips from the hole and at the same time send a sufficient amount of coolant to the cutting edge of the tool. Generally, twist drills are difficult to meet this requirement. When drilling a deep hole with a larger diameter, an internally cooled twist drill can be used to input the coolant through the hole in the drill body under pressure or through a small tube placed in the groove on the drill body. To drill a particularly deep hole, a special internally cooled deep hole drill bit must be used for forced input of coolant under high pressure while flushing out the chips appearing in the hole.
