essary diameter (see fig. 7.1).
• In order to avoid splitting of the surface at an exit
point of a drill bit when drilling holes in wood, follow the
instructions shown in figure 7.2.
• In order to decrease dust production when drilling
holes in walls and ceilings, take actions indicated in
fig. 8.

to improve the drill centering accuracy and to save
the glaze from damage, apply adhesive tape to the
presumed hole center and drill after that (see fig. 9).
Start drilling at lower speed increasing it as the hole
deepens�
Screwing the screws (see fig. 10)

prevent cracking of the work pieces, first drill a hole
with a diameter equal to 2/3 of a diameter of the screw�
