This unit sits in the jaws of your bench vice (100mm+ recommended). It retains itself in the vice with strong recessed magnets.
One half consists of the familiar blade that bends the sheet metal. The other half in the 90 degree recess that the blade pushes into.
By carefully positioning the sheet, you can perform a perfect 90 degree bend as good as a workshop! The blade is segmented, just like a workshop pan break, so that you can make partial bends.
With a little practice, you will be able to fabricate brackets, small boxes & other metal assemblies like a pro.
Warning: This unit is not particularly cheap. It is, however, very well made. It is cast steel with tool steel pressing components. You need it to be sturdy, otherwise it would break or flex. It will, literally, last a lifetime.
Will fold sheet up to 125 wide, however there are 3 x press segments 2 x 50mm, 1x25mm and these are independently removable by Allen head set screws. Depending on the width of the material you could easily bend steel strips up to 4mm thick and 25mm wide. Aluminium should not be a problem up to 4mm thick & 100mm wide, depending on your vice.
