    Abstract: A cryogenically cooled boring tool design reduces the effect of cryogen coolant on a workpiece caused by coolant leakage and coolant exhaust. A tool body has a cartridge for holding a cutting tool insert and a coolant supply path through the tool body and the cartridge for supplying cryogenic coolant to the tool insert. A feed transfer tube connects the coolant supply path in the tool body to the coolant supply path in the cartridge. Insulating tubes line portions of the coolant supply paths in the tool body and the cartridge. The shrinkage rates of the feed transfer tube and the insulating tubes cause the press fit of the insulating tubes to tighten the seal between the insulating tubes and the feed transfer tube when cryogenic coolant flows through the supply path. The exhaust ports on the tool for boiled-off cryogen remains outside of a workpiece bore.
