Overview
The EBS system is capable of producing single and double
back box holes in all masonry materials. The pilot drill and
Tri-Cut round cutter are capable of forming round, at
backed holes in any masonry material. The Tri-Cut round
cutter removes the bulk of material. The squaring off part of
the operation is then carried out by using either the square
cutters in softer masonry i.e. medium density blocks and
soft bricks) or the 80mm wide
HM chisel in hard materials such as engineering brick etc.

Safety and Power Tool Recommendations
Wear safety goggles, gloves and ear defenders at all
times when using EBS products & Channelling Chisels.
Whenever the power tool is not in use, ensure the power
is turned off.
It is advisable to wear a dust mask even when using the
Tri-Cut round cutter with the dust collection unit attached.
It is recommended to only use the square cutters if your
power tool has roto-stop facility (chiselling function).
However, the square cutters have a safety mechanism to
prevent any mishap should rotation function be left on or
if they are used in a power tool without the facility to turn
rotation function off.
Power Tool Recommendations
It is recommended to use EBS products in an SDS + machine
with the following specications:-
4
Ideally a machine with roto-stop facility (chiselling function)
Minimum weight of 2.3Kg
Minimum impact energy of 2.4 joules
Minimum wattage of 850 watts.
Less powerful machines may be used but speed of cut with the
Tri-Cut round cutter will be slower and overheating of the power
tool is possible after prolonged use.

Operating Guidelines Single Back Box Sinking

Materials
Your EBS drill is designed for use in block and
brick type materials using SDS Plus Hammer
Drilling Machines. As a general guide, the
harder the materials, the slower the drill will
operate and the faster it will wear. There are an
enormous variety of different types of masonry
materials, but the following is intended as
a summary of the most common and their
suitability or otherwise for
the EBS drill.
Common Block and Brick
The EBS is ideal for these types of materials and has been
designed and developed to work at its most effective in these,
the most common and softest masonry materials.
Hard Bricks
Typically, engineering bricks or blue bricks can be cut with
the round cutter but not with the square cutter. For this type
of material, use the EBS Hard Material Chisel to produce the
square hole. Speed and life of the EBS may be affected by
drilling in these materials.
Wet / Green Masonry or Uncured Concrete
Typically engineering bricks or blue bricks can be cut with
the round cutter, but not with the square cutter. For this type
of material, use the EBS Hard Material Chisel to produce the
square hole. Speed and life of the EBS may be affected by
drilling in these materials.
Heavily Cavitied Bricks
These may be drilled, but the operation can be difcult and
complicated. Due to the cavity in the brick, it is difcult for
the pilot drill to be supported and therefore centre in the
material. This can cause problems and a neat result is difcult
to produce. If the brick is too heavily cavitied, then mounting
the switch box will also be difcult due to the potential lack
of resulting solid masonry. Use in this application may lead to
failure of the guide rod due to lack of support.
Mortar
Drilling the pilot hole into mortar results in lack of support.
This may cause problems with the nished quality of the hole.
Use in this application may lead to failure of the guide rods.
STAGE
1
Form a Round Hole
A
Drill a pilot hole in the wall
using a 6mm SDS+ drill bit. This
should be at the centre position
of the required back box hole.
Insert the Tri-Cut round cutter
B
into the power tool.
Take the Tri-Cut round cutter
C
and position the guide rod in the
pilot hole.
STAGE
SOFTER MATERIALS
Squaring Off with
2
Square Cutter
A
Insert the square cutter into
the power tool. Switch machine
to ‘hammer only’ mode i.e.,
disabling the rotary action.
B
Bring the assembly to the
wall and locate the guide rod in
the pilot hole.
Position the square cutter
C
so its top edge is level and
push onto the wall to prevent
movement.

Squaring Off with
HM Chisel
A
In harder masonry materials it
will be necessary to square off
using the hard material chisel.
Insert the chisel into the power
tool.

Commence drilling with
the Tri-Cut round cutter on
rotary and hammer function
to the desired depth of back
box to be sunk. The Tri-Cut
round cutter with dust
collection unit tted has a
maximum drilling depth of
approximately 47mm.
Withdraw the cutter from
E
the hole and empty any
debris collected by the dust
collection unit into a suitable
receptacle.
D
Use the hammer action
of the power tool to “punch”
the square cutter into the
wall. It works like 4 chisels
all chiselling at the same
time.
E
Withdraw the cutter
from the wall and brush out
any debris, a square hole
should now be ready for the
insertion of a back box.

On the wall where the back box is to be located,
A
mark the centre of the back box hole. Drill a pilot hole
at this mark using a 6mm SDS drill bit.
Place the peg of the spacing template in this pilot
B
hole and hold in place horizontally.
Drill through the 2 guide holes with the 6mm SDS

drill bit, these form the pilot holes for the round cutter.
Then remove the template.
Follow the instructions for “(1) forming

a round hole” from the single back box sinking
instructions. But, instead form 2 round holes to the
required depth using the outer 2 pilot holes of the
3 on the wall. The dust collection unit should be
positioned covering the rst of the 2 round holes
when drilling the 2nd to minimise dust.
In medium density block and softer brick, follow
F
the instruction for “B – squaring off with the square
cutter”. But, instead use the double square cutter
inserted into the centre of the 3 pilot holes in the wall.

Tips

For optimum speed, when sinking multiple
back boxes, drill all pilot holes, round holes
and complete all squaring off sequentially as
opposed to completing the whole operation
from start to nish at each location. This will
minimise time lost due to tool changes.
It is possible to produce double back box
holes using the single square cutter. Simply
drill two 6mm pilot holes in a horizontal line

User Guidelines Channelling Chisels
The following usage
guidelines should be
followed. Failure to
follow these instructions
could lead to product
failure. Chisels that have
been broken due to not
following these guidelines
are not warrantable:
Usage
A little grease should be applied to the
SDS shanks before use. Silicone grease or
Molybdenum Disulphide (MoS2) is advisable.
Armeg channelling chisels are designed for use
in materials such as medium density block,
soft bricks etc. They are not designed for use
in hard materials such as cured concrete, hard
concrete blocks and harder bricks.
Try to minimise leveraging action.
It is advisable to use the chisel for no longer
than 20 minutes at a time. If used for this long
they should be removed from the power tool
and allowed to cool in still air before being
used again.

Sharpening
When the cutting edges become blunt they
can be sharpened using a good quality le or a
grinder. Try to maintain the cutting proles that
were present when new.
