An anchor to inhibit rotation of a device relative to an oil well casing, comprising a tubular mandrel adapted for direct or indirect connection to the device; a cylindrical housing to receive at least a portion of the mandrel concentrically therethrough, the housing being rotatable relative to the mandrel and having a plurality of circumferentially spaced apart apertures formed in an outer surface thereof; a plurality of spaced apart anchoring slips disposed between the housing and the mandrel in registry with respective ones of the apertures in the housing's outer surface; first biassing means associated with the mandrel for rotation therewith in the clockwise or counterclockwise directions to engage and then move respective ones of the anchoring slips radially towards and then into temporarily anchoring contact with the casing to prevent further rotation of the mandrel and the device connected thereto in either of the clockwise or counterclockwise directions; and one or more drag blocks disposed in the housing in registry with respective ones of the apertures in the housing's outer surface to extend radially outwardly therefrom, each of the drag blocks being normally biassed into frictional contact with the casing to inhibit rotation of the housing relative to the casing.
