Tlicn the cupis ready for threading; care beingtaken to have roughing tool extendedfarther than parting tool and also part-ing tool extended further than thread-ing tool so no other tool will comein contact with work than the onebeing used at the time. This com-bination tool saves the operator thetime and trouble of changing threetools, as by the single or old-stylemethod.
