This control valve block module is used when
the tool is to be controlled remotely.
Both (1a) and (1b) detects a signal when the tool
is at the datum position.
External circuitry will be required to
control the speed of advance and retract
feeds.
When using simple control block replace
screw (35) with extended head screw
(383983).
PNEUMATIC MOTOR
Purchase a pneumatic motor from the Desoutter
2HM5 motor series when the unit is supplied
without a fitted motor. To fit a motor, connect the
motor shaft to the input shaft of the feed unit
with the adaptor and keys supplied. Slide the
motor into the mounting and fasten with screws
and nuts.
A valve kit is supplied with the A1 control block
version to control the pneumatic motor. The
valve may be mounted remotely, or on the
drill with the plate supplied. Connect the valve
according to the circuit diagram.

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
4
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.
SETTING DRILLING OPERATION
The drill must be at least 6mm (0.25in) above
the work piece.

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.
