4.2.7 Reducing pipes
We provide suitable reducing pipes for rivets with a mandrel diameter smaller than 3.2
mm for RBx-15 or smaller than 4.0 mm for RBx-20. Reducing pipes reduce the diameter
of the guide tube through the tool and thereby prevent the remaining rivet mandrel from
jamming in the guide tube.

WARNING
Risk of injury due to use of incorrect rivets
Using rivets with the incorrect mandrel diameter can lead to significant
damage to the tool and cause injuries
• Do not use a rivet with a mandrel diameter below 3.2 mm (RBL-15) or 4.0
mm (RBL-20) without a reducing pipe.
4.2.8 Selection of nose piece
You can use the riveting tool for processing different size rivets. When doing so, note the
exact specification of the rivet and adjust the nose piece and reducing pipe, if necessary
(chapter 4.2.7 von page 27).
The maximum riveting mandrel diameter is ø 1.5 - 4.5 mm for RBL-15 and 1.5 – 4.5 mm for
RBL-20, with special traction heads diameters of > 4.5 mm are also possible.
Measure the diameter of the riveting mandrel and select the next largest nose piece.
e.g. riveting mandrel diameter 2.7 mm / mouthpiece HST-MG-32 (3.2 mm max. riveting
mandrel di reducing pipe 040013002). The minimum mandrel length for standard
nose pieces is 30 mm and for security nose pieces 35 mm.
