Impact Wrench Recommendations

[David Kase]

Agreed...
I also think that the oil-less ones are likely not as long-lasting.  
They use plastic type rings that do not require oil.  I prefer to have 
my steel cylinder liner with a standard piston/ring set-up and go 
through the trouble of changing the oil every 2-3 years (home use).
