Price: £9.50
With so many pieces, and costing less than a tenner, it’s unlikely that these bits are made from super-durable S2 steel. But the number of common size duplicates means this set will remain usable for a long time.
As well as the chunky main ’driver, which can be locked over at 90 degrees for extra leverage, there is also a useful mini ratchet.
