The fixation of a packer or other borehole device is provided by explosively bonding the device to the borehole casing in the desired location. The explosively set packer is oriented in the borehole casing on a setting tool which preferably includes a casing scraper to clean the interior surface of the borehole casing, a removable packer to trap a gas pocket in the area where the explosive bonding is to occur and a gas transfer apparatus to form a gas pocket below the removable packer after the removable packer has been set.
