Hazelwell Mill, which stood on the River Rea near Hazelwell Road, was a corn mill first recorded in 1704. By 1783, in common with many Birmingham mills, it manufactured gun barrels until 1886. The buildings, now demolished, were in use as a rubber factory by 1900. Stirchley Industrial Estate was built on the site in 1978.
Hazelwell Mill was established in the late 17th century to grind corn for the sub-manor of Hazelwell in Kings Norton

In about the mid 18th century it was converted to the boring of gun barrels. The boring and grinding of gun barrels continued into the latter half of the 19th century.
