ABSTRACT:
A tube bending tool for bending tubing, such as electrical metal tubing or plumbing tubing, signals the user by an indicator such as a audible signalling device when the tubing has been bent to a predetermined angle. The tool includes a bending anvil with a tube receiving area such as a tube receiving groove which receives the tube as it is bent, the greater the length of tube received by the groove the greater the degree of bend in the tube. A plurality of sensors such as switches are spaced along the tube receiving area so that as the tube is received by predetermined locations along the tube receiving area, a sensor changes state. A selector switch is coupled to an indicator and power source so that when a selected sensor changes state, indicating a predetermined degree of tube bend has been obtained, the indicator is activated.
