The Cordless Duct Slitters from General Machine can longitudinally slit long sections of duct with an inner duct cutting range of 1 to 5 in. for SDR 9 and higher. Serial numbers for the duct slitters are 70427, 70546, 70547, and 70548. Certain models can cut both longitudinal and orbital slits in duct. Cutting depth is adjustable and converting to another size is easy with the conversion plates. Unloaded, the blade spins at 1400 rpm. The 12-V lithium battery for the duct slitter is rechargeable up to 12.5 Watt-hours with a charging time of 1 hour. The charger and lithium battery are included.
