FIELD: process engineering.
SUBSTANCE: cutting tool comprises shank, head with seat, tool tip to be fitted in said seat and coolant feeder. Said feeder is arranged nearby said head and has the case to receive and to feed coolant via channel made in said feeder. Besides, it has nozzle engaged with the case to displace relative thereto between first position whereat it extends outward and forward from said case and above tool tip clamp and second position whereat nozzle is pulled in coolant feed channel. Here, at least part of said nozzle extending outward from the element case in first position is located inside said fluid channel in second position and does not extend above aforesaid clamp. Note also that the nozzle is stable in said first position owing to coolant continuous flow that pushes the nozzle outward and forward from element case.
EFFECT: expanded performances.
