It covers a range of 4'' - 48'' cast or ductile iron and C-900 PVC with the use of saddles and chain extensions. Anodized and epoxy-painted aluminum frames provide a lightweight yet sturdy machine for tough in-ditch applications. The swing valve allows easy changeout from drill tap to corporation without main shutdown. Friction style boring bar lock allows faster start with minimal adjustment. Uses Reed DT series drill taps. Interchangeable parts include Mueller?, RIDGID?, Footage?, and Talbot/Salser? drill taps, and Mueller? Reed's Tapping Machine is a better value than the competition and is made in the USA. Reed's TM1000 ships with the necessary parts, including the corp insertion tools. Plus, by ordering the saddles and drill taps separately, one only needs to purchase the right sizes for the job. Additionally, the Tapping Machine can be converted to a drilling machine for up to 2in saddle taps, thus saving money over the purchase of a separate machine.
