I think that one is a hard joint and one is soft – like in wood – the higher number is likely hard in steel. I have this and a Festool TXS and they are nearly identical in power and capability and the FT lists the lower specs. It is plenty powerful for light-medium drilling and driving, which is what it is designed to do. Great drill.
I would agree, Scott, specs based on hard and soft joints are usually quite a bit different. Most mfg base their specs on soft joint performance.
