Mounting Clamps
A range of clamps bases and columns are
available.
Full details obtained from Desoutter.
Hydraulic Check Unit (HCU)
The tool will function satisfactorily, when drilling
a blind hole at the set feed rate.
Should it be required to break through the
material and possibly through into another hole,
feed acceleration will occur with possible drill
breakage.
To obviate this, the fitment of an HCU is strongly
recommended.
Request information from Desoutter.
Peck Feed Drills
The Desoutter Peck Feed Drill System should be
used when the depth of the hole to be drilled is
five or more times the hole diameter.
This helps clear drill chips and avoids excessive
overheating of drill bit.
Hole size accuracy can be improved and drill bit
run-out can be kept to the minimum.
Request information from Desoutter.
TENSIONING THE DRIVE BELT
2.5mm
Figure 6
The drive belt will need to be tensioned regularly
depending on the application the tool is to be
used on.
lncorrect tension will lead to rapid wear and can
cause damage to the belt.
Ensure that the electrical supply is
disconnected.
● Slacken the screw in the tensioner.
● Rotate the tensioner so that the tension in the
belt permits the belt to deflect 2.5 mm when
a load of approximately 4 kg is applied to the
belt in the position shown.
● Hold the tensioner in position and tighten the
screw.

This setting details a unit with a HCU,
reference to the HCU should be ignored
when setting the standard tool.
● Set the gap between the (1) and (2) to equal
the depth of drilling required PLUS the
distance the bit is above the work piece, by
sliding (3).
● Lock in position with (4) to the recommended
torque.
● Position the HCU in (3).
● Set the gap between (6) and (7) to a distance
as required above the work piece.
● Unscrew (8) away from the HCU to adjust the
resistance within the HCU to the minimum.
● Fully open the Figure 3 (13).
● Close Figure 3 (11).
● Connect the air supply and press Figure 3
(6).
● Adjust Figure 3 (11/13) to give required
advance, retract feeds for the operator.
● Use Figure 5 (1) for the final depth
adjustment.
● Lock using Figure 5 (9).
● Carry out a set of trial drillings to determine
the ideal advance and HCU settings using
Figure 3 (11).
