This is a 8 head combination 16-gauge hydraulic Notcher, equipped with five (5) slip & drive heads, along with three (3) TDC TDF or TDX notcher heads for notching for TDC Flange style ductwork. Wired 230-Volt 3-Phase, the machine runs very nice, no issues. See videos below and then call us at 412-921-2800. Many additional photos available upon request. Thanks.
