Bradford Building Supplies in Ross-on-Wye were burgled last week when two men stole power tools worth several hundred pounds.
The thieves got in through a fire door at the back of the building just after 6pm and took five cases containing Bosch, Makita and DeWalt tools.
Police have released CCTV images and descriptions of two men they would like to interview.
One is white, in his 30s, cleanshaven and wearing dark jeans, light trainers or shoes, a long-sleeved top with lighter grey panels running under the arm, and a dark green baseball cap.
The second was also white, shorter and younger, wearing a long-sleeved rugby-style top with thick horizontal blue and white stripes and a black beanie hat.
