PROBLEM TO BE SOLVED: To cut reinforcing bars at a designated size without changing a setting value even if a length of a reinforcing bar material is varied. SOLUTION: The reinforcing bar cutting device comprises a transfer means 8 to automatically transfer the reinforcing bar 1 from a cutting preparation area 6 to a reinforcing bar cutting area 7, a stopper 17 to stop the bar 1 at the front end of the bar cutting area 7, a cutting means 9 to automatically cut the bar 1 positioned by the stopper 17 in the bar cutting area 7, and a collecting means 10 for a cut piece of the bar to collect the cut piece of the bar between the stopper 17 and a cutting position 15. A first detection means K1, a second detection means K2 and a third detection means K3 to detect the designated part of the bar respectively are installed, and a control mechanism C is arranged to execute various controls automatically changing in relation to the detection result by each detection means. The collecting means 10 for the cut piece of the bar is so arranged that a product piece of the bar 1A generated by the execution of the bar cutting control and a scrap piece of the bar 1B generated by the execution of the scrap piece collection command control are separately collected in an automatic manner.
