The TriStar Chisel from Shamrock Pipe Tools utilizes a front penetrating nozzle for boring through blockages and/or blocked lines. The unit avoids hang-ups and is easily retracted from sewer lines. It is constructed out of heat-treated alloy steel for durability, with yellow zinc plating for corrosion resistance and replaceable carbide inserts for long service life. 800/633-7696; www.shamrocktools.com.
