Thanks. It is this one:
DeWALT 3/4" 375rpm Drill/Power Unit (DeWalt-DW138) - PriceGrabber.com
The funny thing is that 1/4" bit drilled very well on some mild steel angle iron with a smaller 1/4" hand drill. The 3/8" bit was new. The psi figure for the drill point is useful for calculating forces. Maybe these D-handled drills are more oriented towards drilling wood.
