DESCRIPTION
Covered under Patent No. 5,485,727
WARNING
:
The balance of this tool is designed for horizontal use and is not ergonomically best suited for all applications.
Gage Bilt will be pleased to advise for your specific application.
The GB745 is a pneumatic-hydraulic tool designed specifically for the efficient installation of a wide range of blind rivets, lockbolts
and MAGNA-GRIP® fasteners. It weighs just over 7 lbs. (3.26 kg) and can be operated in any position with one hand. It has
a .620” (15.75 mm) rivet setting stroke and a rated pull load of 6,300 lbs (28.02 kN) with 90 psi (6.2 bar) air pressure at the air inlet.
The GB745 riveter operates on a wide range of air pressure, with 90 to 100 psi (6.2-6.9 bar) providing the maximum efficiency. At 90
psi. (6.2bar) air pressure, the GB745 does not exceed 81.5 dB (A) and consumes 6.0 cfm at 20 cycles per minute.
The air inlet is provided with 1/4-18 female pipe threads for accepting the user's air hose fitting.
Nose Assemblies that were designed for the model 353 installation tool mount directly on the GB745 without the use of an adapter.
Nose Assemblies that were designed for the model 352 installation tool will attach to the GB745 with the use of the 353352 nose
assembly adapter.
NOSE ASSEMBLIES ARE NOT FURNISHED WITH THIS TOOL AND MUST BE ORDERED SEPARATELY (SEE PAGE 12).
