6.1) Assembling the broachcutters (Ref. to Figs. 8-11)
6.1.1) Insert the pilot bit in the cutter from the side of the spigot.
6.1.2) Using the lever (36), position the spindle shaft (07) so that both grub screws (18)
become accessible and suffi cient space is provided to insert the cutter; if necessary rotate
the spindle shaft manually and suffi ciently by inserting the 4 mm male hexagon key in the
appropriate intermediate gear housing (30) in the crankcase of the drill corresponding to
the feed handle (71) (see Fig. 11).
6.1.3) Insert the cutter in the spindle shaft so that the two engaging dogs on the cutter
spigot line up with the grub screws.
6.1.4) Clamp the cutter by fully tightening the grub screws by means of the 4 mm male
hexagon key.
6.1.5) Check that the guide bit slides freely by applying slight pressure on it.
6.2) Assembling the special spiral bits (Ref. to Figs. 9 - 11)
6.2.1) Using the advance lever, position the spindle shaft so that both grub screws beco-
me accessible and suffi cient space is provided to insert the spiral bit; if necessary rotate
the spindle shaft manually and suffi ciently by inserting the 4 mm male hexagon key in the
appropriate intermediate gear housing in the crankcase of the drill corresponding to the
feed handle (71) (see Fig. 11).

DBG-LY over rail clamp
and the specifi c shoes
(combination) allows
the positioning on both
sides of the rails. Use of
2" depth of cut broach
cutters
– Use on girder rail (Ref. to Fig. 21 a-b, example for 128 GR or GGR 118)
– Use on running rails (Ref. to Fig. 22)
(narrow passage of the articulated arm)
Drilling by the guard rail DBG-GR
over rail clamp equipped with TDB 1 termination.
