Apparatus for cutting notches in the ends of tubing comprises an upright support and a horizontal base member. The upright support includes a ram guide and leverage mechanism for reciprocating a ram. The ram is provided at its lower terminal end with a cutting die which is initially positioned above the lower edge of the tube to be notched and moves through the tube during notching. The tube is supported on the base by means of an arcuate cradle or tube support, and the base includes adjustable mechanisms and stop means for varying the position of the tube support.
