The brand emerged when Royston Siddons' Siddons Drop Forgings turned to tool making to fill post war shortages after World War II.

Original production of Sidchrome tools was in Brunswick, Melbourne, Australia.

[1][2] Sidchrome closed the Australian factory and ended all local manufacturing.

In 1996 Stanley Black & Decker started to move all tool manufacturing to Taiwan, whilst sourcing various items from Proto in the USA (marked as Proto on items) due to supply of left-over Australian-made tools being sold out until all manufacturing was fully established in Taiwan.

[3] Sidchrome is still a top selling automotive tool brand in Australia and New Zealand[citation needed] and since 2007, the brand sponsors the Most Improved Award in Australia's Supercars Championship.
