Why Dathan?


Dathan can trace its history back to just after the First World War, when the company was formed by two ex-David Brown apprentices - Harry Moorhouse and Frank Rushworth. The pair met in the Navy in 1916 and then established the business in Huddersfield after the war, naming it after the Admiral who had signed them both on the ship.

Harry and Frank began by producing vernier measuring instruments, but progressed to gear cutting tools during the early 1940s. We have focused on them ever since and have established ourselves as industry-leading specialists, with key skills retained and passed down as new employees join us.
