Working with power tools all day every day, tradespeople and other intensive users are more likely to encounter risks to safety and health. This should be taken into account as part of your Bosch green vs blue decision-making process, since Bosch blue tools offer a host of features that offset risks of this kind.
Imagine you are drilling into a concrete wall when the bit unexpectedly meets rebar. If the clockwise-revolving bit suddenly stops, the body of the tool would spin rapidly in the opposite direction, potentially causing injuries. This is called kickback, and many tools in the blue range have a feature that protects you against it. An electronic sensor will detect the dangerous spinning movement almost instantly and stop the motor.
Here is another common safety scenario. As we all know, tools can sometimes be dropped – accidents happen. But when the tool in question is an angle grinder, for example, the spinning blade could cause a serious injury to feet or legs. That is why blue range tools incorporate a sensor that detects the drop at the instant of impact and stops the blade or bit.
A third safety example, which may have a ring of familiarity for you, relates to plug-in tools. On sites, there are many circumstances under which the mains power can be interrupted. The danger arises when power is restored unexpectedly. A tool could still be plugged in and switched on somewhere, and, in that situation, you would definitely not want it to restart in an uncontrolled environment. With a Bosch Professional blue power tool, this will never happen, since input is required from the user before the tool can be started again.
