This jackhammer is larger than I expected, not in length but in width and girth. The swivel head is larger than normal and pivots around the stem rather than in the stem. I think it will make him much stronger. I've broken snap-on-breakers before so we'll see how it fits. Sometimes all you need is an 18" breaker, even though it's very large and won't fit in every area under your hood. It would be good to remove the nuts on the wheel, it has great leverage.
