About Us

At the beginning of the 20th century, Virgile Amyot manufactured precision tools used by Swiss watchmakers. In 1925 in response to industry demands, Mr. Amyot and his sons expanded their business. Using their tool-making expertise, they manufactured a new type of drill chuck which tightens without a chuck key. It was patented in the U.S. in 1932.

Respecting the precise and exacting standards required in timepiece machining, LFA quickly established its reputation as the leading company on the continent for the production of keyless chucks. Over the years, LFA has continued to develop new and better chucks to fit customers needs, creating a full range of chucks and other products to handle all types of fixed and portable tool applications.

In 1994, LFA patented their newest addition: a keyless chuck which can be used on all corded, cordless, and hammer drills. With this new line and LFA's other products, we can satisfy customer needs worldwide.
