Re: Oz Connection
Mine is the one on the left.
No. 75 was designed for drilling small holes, up to about 1/4", and it will also drive small screws provided it is fitted with a tapered ended type brace bit with a screwdriver tip adapter. The model No. 75 was call a push brace, since it has a brace like chuck. Also, you can see it has an a concealed spiral shaft as it is fully extended. The spiral shaft and spiral mechanism is what makes the spiral system work, so when you push the handle in, the bit that is locked into the chuck turns in either the clockwise or counterclockwise motion depending on the setting of the slide switch on the side of the drill.
