OPERATING INSTRUCTIONS and HOW TO CUT OFF THE
WORN PART OF THE DRILL BIT AND MAKE NOTCHES
Segment guide Index pin holder
1 Decide the number of segments that
should be rebrazed on the new rim of the
core bit. Adjust the index pin holder on
the scale that positions the pin over the
index plate. (Refer to the segment guide
located at the end of this manual).
2 Select the side (A or B) of the indexing
plate that corresponds to the core bit
dimensions.
Index plate – this image shows side B
Make sure the surfaces are clean before
placing the index plate on the blank base
plate. Then place the index pin holder in
position over the index plate.
When mounting the core bit the guide pin
should always lay in one of the holes of
the Index plate
2 1
3 Lock the core bit by sliding the core bit
attachment to the end of the slides
(opposite from cutter head). Then twist
the barrel clockwise until the level (1) in
the bottom reach the stop bolt (2). Turn
the barrel so it is fasten properly on to the
core bit attachment. When demounting
the barrel do the same procedure but the
opposite way

4 The matrix A1 has three different radii.
Choose which radius is suitable for the
core bit. (Position "D" is only for the 16
mm or 20 mm matrix):
Ø 55-90 mm A
Ø 90-200 mm B
Ø > 225 mm C
Ø > 35 mm D
See also the red plate on the tool set
The matrix A2 and A3 are for radii >/= 35
mm resp. >/= 45 mm
To change position of the matrix loosen
the handle which locks the matrix and
lower enough for the guide pin on the
bottom of the head to come free
VERY IMPORTANT
Guide Pin
5
Be sure that the guide pin on the bottom
of the cutter head fits into the hole on top
of the matrix for the new position
6 Tighten the handle clockwise. After the
matrix is secured in position carefully
check that the cutting knife moves freely
into the matrix.

Loosen the locking lever (A) on the tool.
Lower the cutter head over the edge of
the bit (use the handle (B)) until the
cutting knife (C) is below the worn part of
the barrel and the matrix is inside the
barrel. Make sure that no segment parts
remain where the cut is to be made.
Lock the cutter head in position by
turning the lever (A). (The lever is spring
loaded and can be positioned by lifting
the handle from the shaft and then
turning.)
Move up the height adjuster (D) close to
the wheel (E) underneath on the cutting
tool and lock the lever (F).
Cut the slots for the segments as the
index pin drops into position on the index
plate. Turn the bit clockwise to prevent
unscrewing from the threaded bolt on the
mounting attachment.

11 After the first round, loosen the locking
lever (A) and raise smoothly the cutter
head by lifting up the handle (G) to the
required depth of the notched seats 0 – 5
mm (0” - .197”).
Each line on the scale corresponds to
approximately 1 mm.
Lock the cutter head in its new position
with the lever (A) and, this time, cut
between the slots which were cut for the
segments. Cut all the way around and the
top of the core bit can easily be removed.
Now ready for brazing!

CHANGING THE MATRIX AND KNIFE
1
Remove the existing matrix by turning the
handle counter clockwise. Place the
cutting handle so that the blade stays in
its back position.
2 Loosen the allen screw which holds
existing blade. Pull it out and replace with
the new cutting blade and re-tighten.
3 Insert the new matrix. If the replacement
matrix and blade is the 16 mm or 20 mm
size the arrow on the top must then point
to the "D" position. Tighten the handle.
Guide Pin
4
Be sure that the guide pin in the bottom of
the cutter head fits into the hole on the top
of the matrix.
5
By moving the cutting handle back and
forward, check to make sure that the
blade slides accurately into the matrix and
tighten the handle clockwise.

MAINTENANCE
1
Adjust the height of the guide pin if the bit
runs heavily, or too easily, between the
stops on the indexing disc.
H
2
Keep the sliding shafts (H) clean from
concrete dust and cutting parts. Lubricate
the shaft now and then.
I
3
Lubricate the excenter wheel by the
cutting handle (I) now and than.
