A breaker bar is a heavy-duty hand tool featuring a solid metal shaft and a pivoting drive head. Without the delicate internal gearing of a ratchet, it can withstand massive force to break loose stubborn, rusted, or over-tightened fasteners. Machinists and mechanics reach for this tool before resorting to heat or impact wrenches.
