Tube bending with dedicated hand benders is desirable for parts that do not lend themselves to CNC bending. Dedicated hand benders are designed to make one part and cannot be adapted to make others. This is especially handy on parts that have tight bends with little distance between tangent points. Hand benders are also more adjustable than powered ones.
