A pipe breaking assembly (100) is shown with a modular design that allows a user to more economically purchase a single base unit (110) that is adaptabl e using a number of elements. Combinations of elements such as blade portions (130) and expander cones (140), etc. allow the modualr assembly to be tailor ed to a variety of job conditions. A pipe breaking assembly (100) is shown that includes a particular configuration where a blade portion (130) is located i n front of a shortened expander cone (140). The shortened expander cone (140) provides a lower contact area that in turn reduces friction.
