is formed on an internal portion of the cutting tool body 22 and an axial forward end 71 of the coolant channel 70 is in fluid communication with the pocket 58 of the base portion 54 this configuration provides for the nose portion 56 of the head portion 32 to be positioned adjacent to the internal coolant channel 70 that extends through at least a part of the base portion 54 of the head portion 32 in operation of the rotatable cutting tool 20 of the invention a coolant is passed through the internal coolant channel 70 in the direction indicated by arrows 72 the coolant passes from the coolant channel 70 to the pocket 58 of the base portion 54 once the coolant reaches the pocket 58 the coolant is able to contact the nose portion 56 which as described is movably mounted within the base portion 54 it will be appreciated therefore that due to the nose portion 56 being movably connected relative to the base portion 54 that the nose portion 56 does not have a snug or interference fit that would prevent the coolant from passing over the nose portion 56 and moving toward the axial forward end 60 of the base portion 54 once the coolant passes the axial forward end 60 of the base portion 54 it continues to flow toward the axial forward end 24 of the nose portion 56 and toward the hard tip cutting insert 30 advantageously the coolant provides for cooling the hard tip 30 during a cutting operation of the rotatable cutting tool 20 this provides for the working temperature of the hard tip 30 to be regulated within desired limits during a cutting operation in order to increase the useful life of the hard tip 30.
