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).
