This 4- in -1 tube bender takes diameters 5mm, 6mm, 8mm and 10mm. Bend hollow tubes in brass, copper, aluminium and thin wall stainless steel tubes from 0 degree to 180 degree. If bending rods anneal the metal by heating to cherry red and insert into perlite powder for slow cooling.
To bend, hook on one end to the anchor bar and bend with the guide pad handle. Aerosol silicon release to groove helps in smooth bending.
