FX Series breakers feature a mono-block design, and with only two moving parts, hammer operation is simplified and the chance of downtime is reduced. The advanced hydraulic circuit provides increased flow to the valve and piston, resulting in faster cycle times, increased tool penetration, and more productivity per hour than predecessor models. According to the company, there are no Through-Bolts to constantly torque or replace, and the front wear bushing is easily replaced, so the hammer is always in perfect working condition.
