The Stanley breast drill 748 / 748A (also known as The Continental) is a large hand drill fitted with a hardwood side handle, a winder with a hardwood handle and a shaped breast plate. A shaped breast plate is designed to be positioned comfortably at the top of the chest. This positioning of the drill against the body allows extra exertion to be applied while maintaining good control. This control is further assisted by holding the side handle to help maintain stability.
It gives the option of two different speeds available at its disposal. The drill can operate with gear ratio 7.2-1 or 2.33-1. The two different gear ratios cater for drilling into different materials with different drill sizes.
The 748 breast drill was originally Stanleys most expensive hand drills.
