Dotco Drills - Advantages
Full feathering is achieved
with the aid of our valve
design with the pressurised
tip for speed control during
drilling.
Low noise levels increase the ease of
use of the tool.
The trigger only
needs to be pressed
gently to operate.
Protective lip under the trigger
keeps the other fi ngers safely
away from the trigger function.
The design features double ball bearings for the drive spindle - pre-loaded
to ensure longer bearing service life and better spindle control. Vibration
and runout are reduced.
The proven motor and gear design is well
balanced. Vibration is reduced and the
general service life of the tool increased.
Rubber grip provides
thermal protection, isolates
vibration and in this way
increases comfort.
Each tool is individually checked, aligned and
adjusted on our workbench to reduce the
runout. Vibration is reduced to a minimum.
Gears are manufactured from steel alloy
and heat treated. Fixed casings ensure
low vibration operation.
Ergonomically important fi nger and thumb guides fi t well in
the hand and aid control.
The housings are manufac-
tured from robust yet light
industrial aluminium.
Handles are shaped to the
human hand. They are fl at
or round depending on the
requirement.
The handles for the series 14 are of oval design, as it is
this shape that fi ts the human hand better. They are fl at
or round depending on the requirement and therefore fi t
securely in the hand.
A Wonder of Technology and
Ergonomics
We have been able to make these extraordinary improve-
ments thanks to new technology. Prototypes are now avail-
able quickly due to our in-house design platform so we can
develop models in real time, provide prototypes to users and
then further refi ne the ergonomic and performance criteria
with their feedback.
The handles for the series 14 are of oval design, as it is this
shape that fi ts the human hand better. The tool lies securely
in the hand.
Our development work has also resulted in the integration of a rubber grip for better temperature control, as compressed air in the
metal housing make the tool appear cold and reduces speed and effi ciency.
In addition, the objective is direct force transmission so that the operator can use the tool with the greatest possible control, the
greatest possible direct force, the lowest possible angular force and the lowest possible fatigue at the wrist. For this reason we
have developed drills with ergonomic fi nger and thumb guides. And for this reason we have also fi tted a protective lip under the
trigger so that the other fi ngers are kept safely away from the trigger function.
It is only necessary to press the trigger gently. The trigger mechanism comprises a valve with a pressurised tip. As soon as the
trigger resistance is overcome, you can start work.
