Note: In the product column, the numbers in the parenthesis [ ex: (6.5-180) ] designate the die set's center line radius and maximum normal degree of bend. Therefore (6.5-180) would represent a die set with a center line radius of 6.5" and would be capable of producing a complete 180 degree bend. The "Center Line Radius" is the bend radius as measured from the center rotation point of the die to the middle of the tubing. The 'Minimum Wall Thickness' represents the minimum wall thickness for consistent high quality, wrinkle-free bends. Die sets up to 1.25” can bend solid round. Die sets up to 2.5” OD will bend up to .134” wall.

Dies rated for 90 degree bends are actually machined to approximately 115 degrees and 180 degree dies are machined to approximately 210-220 degrees.
