[TowerTalk] Drill motor

I have a Milwaukee Hole Shooter 3/8 corded reversible variable speed
drill. It is over 30 years old and going strong. It has enough torque
to hurt you if say using a hole saw or large bit and it jams. The drill
does not stall. It will wrap you up in the cord making it very
difficult to release the trigger and can hurt you. I have a Hole Hog
(little brother to the drill touted for tower raising) and it is a
powerful tool which can also hurt you if you jam a hole saw or large bit.
I do not have the model touted for tower raising (Super Hog) but it is
reasonable to assume in the progression of hole Shooter to Hole Hog to
Super Hog that the torque capable of being produced escalates with
increasing drill motor size. I don't argue against using the Super Hog
and would use one myself if the situation warranted it but... be
prepared, it is altogether likely you will not be able to hand hold it
if the tower jams. The torque will spike and if the chuck becomes
stationary the drill motor itself will in fact rotate with or without
your body parts clinging to it. These drills have provision for a second
hand grip (removable) which you should use. You should think ahead in
positioning your hands and your body so that if the tower should jam
causingt the drill itself to rotate you won't be injured. These tools
are powerful and capable of doing you grievous harm if you are unwary.
If I were to employ a Super Hog as a tower raising tool (altogether
reasonable possibility) I would design/build a mechanical bracing system
to prevent the drill from rotating if the chuck was stopped by such as
the tower jamming for some reason.
Milwaukee tools have served me well. I don't know that all Milwaukee
tools are high quality but all the ones I have are. I have a Sawzall
and the Hole Shooter that I have used a lot which are both over 30 years
old now. I replaced the power cord on the drill. It is a twist lock
connector that connects the cord to the drill and is trivial to change.
My Hole Hog is only10 years old but I expect it to last.
Want a chuckle? I traded a home built Heathkit H-8 computer and monitor
to a tool store owner for the Sawzall, Hole Shooter, and a worm drive
Skill saw around 1980-82. All these tools are still working perfectly.
The computer, if working, would at best be a historical curiosity.
