The Sepf-Piercing Riveter 10T DF-SPR70 is part of most OEM recommended methods for joining aluminum panels together. The cold forming technique requires no heat and no pre-drilled holes. The user can manually adjust the actuator speed as well as rivet pressure according to the metal used in order to avoid panel distrotion. Rivet aluminum panels (up to 6.5mm with included rivets but up to 9mm with longer optional rivets) together with high dynamic strength. A pressure gauge on the unit illustrates current pressure amount for controlled operation.
