Selection of the right drill depends
mainly on the following two points:
drill bit diameter and
the recommended cutting speed
of the material to be processed.
In the table, the preferred bit sizes
are assigned to the individual drill
types for some common materials.
The table shows the drill bit sizes
with which the individual types are
able to reach the recommended
cutting speeds. However, the feed
of hand-held tools cannot be incre-
ased arbitrarily with increasing bit
diameter, since the necessary feed
force can no longer be applied. For
this reason, the maximum bit dia-
meters for steel and aluminium
are allocated to the individual types
on page 6. These maximum diame-
ters were determined by tests, un-
like the information in the table. In
order to achieve a sufficient cutting
speed with normal hand pressure,
some materials should be predrilled
for the following bit diameters:
steel up to 600 N/mm 2 as of 8 mm
steel up to 600 N/mm 2 as of 6 mm
cast iron up to 180 N/mm 2 as of
10 mm
cast iron up to 300 N/mm
2 as of
8 mm
Note: If only one bit diameter is
specified in the table, it refers to
the lower limit of the recommen-
ded cutting speed. If nothing is
specified, the recommended bit
diameter is outside the clamping
range of the standard chuck.
