We are a manufacturer of fine pitch gears, toothed pulleys, turned and milled parts and assemblies.

Biddle and Mumford's origins go back to the 1860's in the clock trade in the Clerkenwell area of London. Whilst we still make gears for the clock trade industry, we progressed into a general engineering company offering a one stop shop for all your gears, pulleys, turning, milling and assembly needs. Whilst we are an ISO 9001 registered company, most of our business comes through recommendations, through our reputations for producing good quality work throughout our history.
