GB SERIES 
Gap-Bed Hydraulic Punch Presses 40-ton through 135 ton press only models, with a quality for price ratio unexceeded in the industry. The GB is a great buy in any shop that needs solid dependability in a dedicated punch press, yet needs the ability to expand the capabilities of a press to allow shearing or forming for special jobs. With a standard 14" x 9" throat (18" x 18" option) and a 7" stroke length (9" or 18" throat models), combined with a 48" table (* on 70, 100, 135 ton models), our punch presses easily accept a wide range of standard accessories and special tooling.
