Which hot tap machine would meet my needs?

It depends largely on what size tap you need to perform and how you plan on using your machine. For commercial use, and for taps up to 6”, the TapMaster TM-1 Pro Series is the model that will hold up to daily use. If you need to perform taps 2” or smaller and will only use the machine on occasion, the Wheeler Rex 8100 and the Wheeler Rex 8200 are great manual tapping machines. The Wheeler Rex has additional available for matching up with unique thread patterns where the TM-1 and Wheeler Rex are designed with NPT threads only.
