What's the difference between the K2 and the Pro2 kit?
Both kits perform taps for 3/4", 1", 1-1/2", and 2" services. Both kits also can perform taps on PVC, AC, and Ductile Iron.
We recommend the K2 for those that mostly tap PVC and the Pro 2 for those that mostly tap ductile iron.
The Pro machine comes with more valve adapters, a better drill, and Tiger cutters.
*Tiger cutters are the best hole saws available and are needed if tapping Sch 40/80 steel or stainless.
