Dry drilling - Dust Extraction / Dust Protection

Dust generated during work is harmful to your health. That is why it is advisable to
use a dust extraction unit and to wear a dust mask on dry drilling.
The use of vacuum extraction is also a prerequisite for optimum cutting
performance of the drill bit (air-cooling).
For the selection of suitable drill bits for different materials, please refer to the
specifications of the drill bit manufacturer.
CAUTION
When working, always guide the vacuum extraction hose away to the rear of the
machine so that it cannot come into contact with the core bit.
CAUTION
Please read the operating instructions for the vacuum extraction unit for
information about disposal of the collected material.
NOTE
To avoid electrostatic effects, use an anti-static dust extraction unit.
Dust from material such as paint containing lead, some wood species, minerals,
and metal may be harmful. Contact with or inhalation of the dust may cause
allergic reactions and/or respiratory diseases to the operator or bystanders.
Certain kinds of dust are classified as carcinogenic such as oak and beech dust
especially in conjunction with additives for wood conditioning (chromate, wood
preservative).
