In a bar material supplying device and a numerical control machine tool having the bar material supplying device, a bar material can be chucked even when driving force of a motor is insufficient. The bar material supplying device includes a feed rod (60) having a leading end provided with a finger chuck (61), a feed rod servomotor (74) and an air cylinder device (80) that move the feed rod (60) in a longitudinal direction to insert and pull the bar material (200) into and from the finger chuck (61), and an NC device (90) that controls driving of the feed rod servomotor (74) and driving of the air cylinder device (80). The NC device (90) controls the driving of the feed rod servomotor (74) and the driving of the air cylinder device (80) to move the feed rod (60) in an operation of inserting and pulling the bar material (200) into and from the finger chuck (61), and operates as an error allowable device that allows an error of an operation amount of the feed rod servomotor motor (74) in the operation of inserting and pulling the bar material (200) into and from the finger chuck (61).
