Hand operated mandrel tube bender.
It is widely recognised when bending tubing that the normal minimum bend radius is 4 times tube diameter. Attempting to bend on a smaller radius immediately introduces a number of problems, namely rippling on the inside of the bend, cracking or splitting on the outside and extreme distortion of the tube.
For those who need a tighter bend radius we have designed the Useful-Tools hand operated mandrel tube bender. These machines will allow tubes to be bent with an impressive 2 times tube diameter bend radius with no rippling or cracking of the tube and the absolute minimum of distortion.
We have a range of 3 machines that all operate on the same principle, namely the pipe or tube to be bent is located between a formed mandrel and back plate with another formed internal mandrel (bullet) held at a carefully controlled position inside the tube. The tube is secured firmly to the main mandrel and when the mandrel is turned the tube is pulled over the internal mandrel as it wraps around the main mandrel. (This internal "Bullet" holds the tube open and helps reduce distortion to a minimum.)
We can supply machines that will bend from ¼" diameter up to 1.5" diameter, all on a 2 times tube diameter bend radius, and in some cases down to 1.25" times tube dia.
We carry a large range of mandrel sizes and can cater for millimetre and special sizes.
Check out the attached video showing how easy the machine is to use.
Hand operated pipe beading tool.
An essential workshop tool that allows a controlled bead to be raised quickly and easily on the end of pipe or tube ranging in size from ½" diameter up to 4.0" diameter, in aluminium alloy, brass and copper. It can also if used carefully raise a bead on 18swg mild steel tubing.
