Biddle and Mumford remains one of only a handful of speacialised British manufactuers of very small to medium sized gears and gearboxes (current capability ranging from 2 to 116mm diameter). However, there is much more to the company than just gears, as it is now a major producer of precision turned parts and also produces the Falcon and Lang nibbler tools.


We have specialised machines capable of producing high precision fine pitch gears used in aerospace, defence, ophthalmic, paper handling, model engineering, clocks and many more.


The other area of expertise is in the production of tooth pulleys, especially in small sizes. The company produces MXL, XL, L, HTD and T series pulleys in all materials for a wide UK and export client base.



Offering years of engineering knowledge

and enthusiam


With the years of knowledge and gained over the years within the industry, we are very passionate about all our projects and welcome any new challenges. As well as gears being our frontier, we have embraced many different projects with success.
