I used an 18 VDC DeWalt driving a 3" hole saw to cut a hole in the aft
end of the keel for the propshaft tube of the boat I'm building.
Drilled a hole thru 3/4" of epoxy and double bias knitted glass.
By comparison, drilling that same hole thru a piece of hickory is a
piece of cake.
Had to replace the bimetal hole saw, but the drill is still working.
BTW, my corded drill is a 1/2" right angle unit for drilling large holes
with a hole saw.
My _primary_ drill is also an 18v DeWally, with two batteries that have been
rebuilt by www.primecell.com (and having experienced the before and after,
that was key to turning it into the hoss it is) ... I rarely have to bring
out the corded 1/2" drive Milwaukee, but I am glad it's there.
I have one of the original Milwaukee 14.4 cordless drills. I use it
almost every day...it's been busy these last few days. Not a hic-up for
almost 5 years.... 1/2" variable speed with clutch. I'd do that again in
For real screw-driving on a serious level, try the Milwaukee 1/2" Close
Quarters drill (Yup it has a tail).
Quite awkward at first, once you're used to it..nothing else will do.
