Improved working environment   Companies are becoming more aware about environmental issues and recognize the need for an environmentally sound production process. One of the major environment hazards in conventional drilling processes is the use of coolants and other chemicals. Not only is the handling of coolant costly and time consuming, it also constitute a threat to the environment.   The Orbital Drilling™ technique provides efficient cooling of the cutting tool and the hole surface which opens up for dry drilling or “quasi-dry” drilling, using minimal quantity lubrication (MQL). This in turn doesn’t only cut costs, it also improves the working environment for the employees.
