Compression Bending: A tube bending method where two dies are used – a die that stays stationary, and a counter die that bends the tubing around that die in order to achieve the desired shape. Roll Bending: When the tube bending process requires large radius bends (bends in which the radius bend is eight times that of the material’s thickness), roll bending might be required. The HB-10 is Huth’s entry level tube bender, designed to introduce you to Huth quality while showing you the incredible profit potential that awaits you. The HB-10 features knee control activation, manual depth-of-bend control and 58,000 lbs. of bending power - more than enough for 3” tubing. As with all Huth Benders, the HB-10 features a.
