Operation
Fastening and adjustment of drill bits
The reversible pris has a sharpening range fro 2 to 20 .
Fixing and align ent of the drill bits is achieved in the si plest
way. The pris is opened by eans of the knurled screw provided
for this purpose. Once opened, insert the drill bit to be sharpened.
Hold the drill bit so that the tip protrudes 15 to 20 . In front of
the cla p. Close the cla p gently with the knurled screw so that
you can still turn the drill bit by hand.
The only thing to do now is to align the cutting edge of the drill bit
so that it is parallel to the two arks shown.
Mark A: for right-hand drills Mark B: for left-hand drills
Once adjusted, we finish cla ping the cla p by hand and we can
now proceed to sharpening.
In addition to the basic settings, the rake angles can be adjusted depending on the
aterial to be cut.
If you want a higher rake angle - ore cutting capacity, you should ove the bit a little
to the left (less angle on the pris ). If you want less rake - less cutting capacity, just
ove it a little to the right.
In this way we can adjust to the angles required for each aterial.
In the case of sharpening a broken drill bit, as it has no cutting edge to adjust, we ust
cut so that it lies flat. Then we can adjust the ends of the cutting edge as close as
possible to the adjust ent arks and resharpen until a new cut appears, and we can
adjust as above.
Cutting angle adjustment.
In order to always work according to the aterial properties, we can infinitely adjust the
cutting angle.
The ost co on cutting angles are 118°, 130° and 80°.
These angles are arked on the base and can be quickly adjusted by opening the cla ping
ca (pos. 6 on page 7) and oving the pris base (pos. 4 on page 7).

Grinding of the grinding wheel
To carry out the dia ond dressing process, loosen the positioning ca on the tool holder
support and set the position to 150°.
Fix the dia ond dresser in the tool holder and fix it by eans of the knurled screw in the
lower position of the holder.
Move the otor s oothly to the right and left while slowly advancing the dia ond dresser
towards the grinding wheel, once they co e into contact, the advance should be s ooth.

Grinding wheel replacement
To change the grinding wheel, disconnect the machine
from the power supply.
Open the two screws 1 and 2 of the guard with a 10 spanner. Re ove the grinding
wheel guard.
Loosen the hexagonal screw with a 4 Allen key. Turn the screw until the grinding wheel
can be re oved with the grinding wheel holder.
Insert the new grinding wheel into the otor shaft and tighten the screw again, then tighten
the grinding wheel guard. Check that the grinding wheel is correctly ounted.
Grinding wheels ust confor to EN 12413 or EN 13236. After changing the grinding wheel,
carry out a 1- inute test run with the otor running. If the grinding wheel does not work
properly, switch it off and look for the reason for the alfunction.
Never use the machine without the grinding wheel cover
installed.

Drill bit sharpening, drill bit clamping and adjustment
The reversible pris has a drill bit range fro 2 to 20 . To
insert and align the drill bit we ust follow a few si ple steps,
open the tool holder by eans of the knurled screw provided for
this purpose, now we can insert the drill bit.
Keep the tip of the drill bit between 15 and 20 . Out of the tool
holder. Then close the cla p slightly by eans of the knurled
screw, so that we can still turn the drill bit by hand. At this point
we should adjust the drill bit parallel to the two existing arks (A
for right-hand drills and B for left-hand drills).
Once the cut has been ade, the cla p ust be closed, do not
start sharpening unless the cla p is correctly closed.
By varying the basic setting shown, the rake angle can be varied
depending on the aterial to be drilled.
If it is required a larger cutting angle, with ore cutting capacity,
then it should be adjusted a little ore to the left (less graduation
on the tool holder). If we want less cutting angle, with less cutting
capacity but ore durability, we should adjust a little ore to the right ( ore graduation on
the bit).
In the case of a broken bit, without a cut to fit, the bit should be sharpened to a point shape.
Align the corners as close as possible to the adjust ent lines and re-sharpen the drill bit
until a sharp edge appears, then adjust as above.
Cutting angle adjustement
In order to work according to the properties of the aterial, the cutting angle ust be
adjusted accordingly.
The ost co on cutting angles are 118º, 130º and 180º.
The angles are clearly arked on the pivot base of the pris . They can be easily adjusted by
opening the ca that holds the base.

Drill sharpening
Wear safety goggles!!
Once the tool holder is properly aligned, fix it on the cla ping base in front of the grinding
wheel (page 6 no. 4) and rotate it anually. At the sa e ti e, ove the feed of the tool
holder in the direction of the grinding wheel by eans of the vernier (page 6 no. 5), until we
have a well-shaped cut.
We note the final position of the feed vernier once we have a well-for ed cut and re ove
two or three positions by eans of the vernier. The drill bit should be oved up and down
until the sparks stop co ing out.
To achieve the best cutting sy etry, the tool holder should be rotated 180º without
changing the position of the feed. The other cut should be sharpened until sparks should
appear.
CAUTION!
To prevent the drill bit from overheating and becoming
crystallised, we must work with small feeds.
Sharpening of bi-diametric drills
For this type of drill bits we ust sharpen the first part as
in the previous process for standard drill bits. The cuts of
the second cutting edge ust be placed in the sa e
position (see the section "align ent and adjust ent of
the drill bit"). Once the drill bit is in the sa e position, we
ust extract it so that it is positioned as shown in the
photograph. Using the knurled screws 7 and 9 we can
achieve the fine adjust ent with respect to the grinding
wheel. The sharpening process is the sa e as described
for sharpening standard drill bits.

Sharpening of drills for sheet metal, wood and milling cutters
For this type of drill we reco end the use of profiled grinding wheels.
Re ove the cla p fro the holder and position it on the adjust ent line of the drill carriage.
The adjust ent of the drill bit is identical to that of conventional twist drills. The fine
adjust ent of the drill bit to the grinding wheel is carried out by eans of the screws
(Positions 7 and 9 on page 7).
Do not start the grinding wheel otor until the adjust ent is co pleted. In the case of
illing cutters the pris is fixed with the knurled screw in the lower position, fixed on the
side of the pris holder (Position 5 page 7).
By moving forward with the vernier, we sharpen one cut and by turning the tool
holder a half turn we can sharpen the second cut. For tools with 3 or 4 cutting
edges we need the magnetic brake (optional).

Core emptying of twist drills
With the new cla ping pris , it is now possible to e pty the
core of the already sharpened drill bit.
1. Holes A and B are for sharpening 4-faceted drills.
2. Hole C is used for coring.
For core drilling, we have to position the drill bit 25 outside
the tool holder without changing its position in the pris .
Outside the tool holder without changing the position of the drill
bit in the pris . Fix the tool holder with the knurled screw in
position C.
Use the upper position of the tool holder. Release the cla p and
position the holder at 90°.
By eans of the tool holder and the ove ent of the otor, we can perfor the core
casting using the left side of the grinding wheel.
Once one side is finished, note the position of the vernier and ove the position back one
turn. Now we can turn the tool holder 180°, fix it again in the hole C and ove the vernier
to the noted position.
