During the friction drilling process following should be considered:

• At the start of work the collet chuck should be retightened after 5-10 times forming. This would prevent the drilling tool from spinning or falling out.
• Protective goggles should be always used during the friction drilling process.
• If the machine has no protective device against ejected chips, suitable protective clothes and goggles should be used while working with the friction drilling tool of the design “cut”, as the resulting collar is removed.
• The friction drilling tool and the processed material is becoming burning hot during and after the use. Therefore, it should not be touched without protective gloves.
