Abstract
A device for helically cutting and automatically removing waste sheathing from the stressing tails of unbonded tendons. The device comprises an elongated body and an attached cutting head. Both the body and the cutting head have a uniform through bore along their longitudinal axis for accepting a post-tensioned tendon. The cutting head comprises an integral blade having a cutting face radially offset from the longitudinal axis and inclined at a pitch angle of between 45 and 85 degrees relative to the longitudinal axis. The blade cuts the sheathing while also ejecting the waste sheathing.
