The British Tool and Engineering Company – the company which founded the Britool brand – first started production in 1908 and Britool has been the number one choice for professional engineers ever since. Demand for the company’s products grew strongly between the wars and, during the Second World War, Britool was the principal supplier of tools to the British armed forces, supplying over 200 million wrenches, sockets and accessories. The widespread use of Britool products during the war brought the high quality of the brand’s products to the attention of a wider audience, significantly increasing market knowledge and making Britool the number one tightening tool brand in the UK. In 1991, in order to consolidate its position as a premier brand in one of the worlds most competitive markets, Britool joined forces with Facom, Europe’s largest hand tool manufacturer. The backing of such strong development facilities and vast technical expertise enabled Britool to maintain its position as the brand of choice for all areas of engineering – from aerospace to industry.

In 2006 Britool and the Facom Group merged with Stanley – the World's largest supplier of tools. Backed by the industrial might and experience of Stanley, Britool began to develop into a more focussed range for the industrial and automotive professional.

In 2010 Stanley merged with Black and Decker to create the world's largest hand and power tool company, Stanley Black and Decker. Around this time, to best meet the needs of the professionals it serves, the company created the Industrial and Automotive Repair division.

Britool has evolved into Britool Expert - the new range of hand tools from the Industrial and Automotive Repair division of Stanley Black and Decker. This new range builds on the heritage that the Britool brand represents to its millions of users and delivers a more comprehensive range of hand tools designed to meet the developing needs of today's user...The needs of today's EXPERTS.

This new, mid-price range has been designed to meet these needs and requirements using specifications produced by Stanley Black and Decker's Industrial and Automotive Repair research and development department. At the same time, it has also been produced to meet all current international standards such as ISO and DIN.
