ENGLISH
Unlike solid drill bits, core hole drill bits
only cut a ring into the material. Since with
this procedure less material is removed,
less power is needed and the drilling
progress is clearly faster than that when
using solid drill bits.
The brad point of the drill is pressed
against the material by resilience, but does
not penetrate the material when drilling. At
the end of the drilling process the brad
point pushes the cut material from the drill
bit and the drill hole.
The maximum retaining power is reached when using steel with a low carbon
content and a material thickness of at least 12 mm.
When drilling in steel with a thickness of less than 6 mm or in non–ferrous metals a
steel plate of at least 250 x 250 x 12 mm has to be fixed on the workpiece. The drill
stand can then be put onto this plate.
Apply the drill stand with the longer side of the magnetic foot parallel to the axis of
the workpiece.
Fill the free space underneath the magnetic foot with steel wedges or steel bars such
that as many lines of magnetic force as possible will run from the magnetic cores via
the workpiece to the magnetic foot.
In doing so the axis of the drill must be pointed exactly to the centre of the workpiece
or the drill might move slightly laterally.
From time to time, apply a few drops of oil to the rack toothing. The bearings of the
feed shaft are self–cutting and must not be greased.
Grease the sliding surface of the carriage with Molykote grease.
