I'm not convinced the clutch is really that essential. I have had many
drills grab in the past and a firm grip stalls them long enough to
release the trigger. These really are two handed tools, so even less
chance of your trigger arm being damaged.

That's my experience with a 2kg bosch-pro sds - using it with the 3-
jaw chuck and largish hole-cutter in timber. With a firm grip,
absorbing the forces of stalling the drill really wasn't a big deal.

I now have a DeWalt high-torque drill for large drillings in timber,
and that's another beast altogether. A much firmer grip, more caution,
and being ready to release the trigger very quickly is necessary -
it'll have a good go at spinning me round otherwise.
