chips and long helicoidal chips.
The chips fragmented in small bits can be rejected from the machining area and can
be dangerous if they reach the eyes of the operator. To avoid this, it is advisable to
wear safety glasses.
The long helicoidal chips tend to roll up the tool and gain considerable volume before
breaking, which is dangerous if they reach the operator as they may produce injuries.
The reached volume may also displace the drill protector from its security position,
increasing the risk of an accident. It is advisable to use chip breaking tools to machine
materials which produce such chips. For further information contact the tool
manufacturer.
