The TN-150M manual tube notcher has three set holes for three desired notches.
The machine is manually operated with the blade notching a set 90° notch to one section of the tube. To create the second notch the tube is to be rotated 180° with the same process then creating the overall final notch perfect for creating strong welding joints.
The three sizes of notch holes measure 1.25″ , 1.5″ and 0.75″ (31.75mm, 38.1mm, 44.5mm).
The machine can be bench mounted or taken onsite to perform perfect notches.
