ABSTRACT:
The invention relates to a rotary tool having at least one replaceable cutting blade, the or each received in a channel and clamped firmly therein. The tool body has a passage in each channel which receives a safety member in the form of a pin projecting into a recess in the blade. In normal use the pin remains out of contact with the walls of the blade recess, engaging with the recess only if the clamping means fail, so as to restrain the blade from falling out of the channel.
