And one Big Double Magnetic Holder. One magnet holds the Screwdriver bit allow quick and easy change over and the other holds the screw allowing single handed screw application.

USH screwdriver bits are unique in the fact that they are cold forged not milled. Therefore tiny hammers beat, compact and compress the steel to form the end theresfore making it stronger. As with milled bits the steel is cut away to form the end therefore weakening the structure slightly.

They are then titanium coated to improve the outside hardness of the bit so making it last longer and provides rust protection.

Then tiny pieces of ceramic are embedded into the end of the bit. This helps the bit grip the head of the screw and so reduces cam out.

Altogther this means that USH bits last longer and perform better.
