Bad news. Today's battery powered consumer grade power tools are
easily destroyed. For example, this is a Milwaukee 9 inch angle
grinder:

The problem is that it's powered by an 18V battery pack instead of the
more appropriate 54V battery pack. The 18V pack will draw 3 times the current of the 54V pack. That causes excessive heating and a tendency
to turn wires and switches into a smoking "fuses". Bad design. Even
used normally, something will blow. The problem is being handled by a liberal warranty policy.

I could on forever on what's wrong with today's consumer grade power
tools, but that's a bit too far off topic. Suffice to say that
today's power tools are very different from what I had become
accustomed to using.

That’s disappointing to hear, I rarely do any DIY the brain injury means my ability to work out problems etc is limited even quite basic stuff required
my wife to break it down and do the thinking, so I could do job’s beyond
her ability mainly reach and strength.

OK. I actually own a brace and also a geared hand drill. Given to
me, never used either.

I've got each of those, used a bit in the past, never in the past
couple decades. I've also got a "Yankee" push drill. It's a
screwdriver shaped gizmo that uses non-standard, non-spiral bits. To
use it, you sort of try to stab the bit into the material. Helical
slots cause the bit to rotate as the handle moves forward. It's
occasionally handy for super simple holes, e.g. a pilot hole in
plaster before setting a nail to hold a picture frame.

I need a masonry bit to get through the plaster in my house. Sure it's
not sheetrock?

Our house was built in 1943. It's plaster. Well, except the addition we
did about 15 years ago. That's sheetrock.

Most of our house was built around 1900, using burnt clay bricks for the
walls and wooden beams and planks for the ceilings. When adapting it to
our needs many decades ago, we removed all the sheetrock that had been
added after 1950 or so.

Drilling holes in brick walls and chiseling slots requires heavy
equipment. At the time, I was using an inherited electric impact drill
that was almost as old as I was; I only acquired a cordless impact drill
with dust extraction much later.

Would have liked to have such a beast in the past, when I did most of
the work. Red drilling dust from bricks is almost impossible to remove
once it has settled on a surface.

My sympathies. I don't know what I would do without getting involved
in repair work. I've tried to teach various relatives and girlfriends
how to use tools and how to solder. Learning to use tools is a skill
that has to be learned very early. My guess(tm) is after about 12
years old learning to handle tools becomes difficult and after about
30 years old, impossible.

I don't know how deep you want to dive into crappy power tools, but
you might find this video of interest:

"Teardown and Review of the all New DeWalt DCN930 Nail Gun." <https://www.youtube.com/watch?v=VNSRuzz1uyc> (1:05:56)
Yes, it's 1 hr and 6 minutes long. The author tears apart the latest
nail gun by DeWalt and compares it with the previous version. It's
not a total redesign, but the differences between the old and new
versions are a clear indication of the downhill trend in quality,
reparability, maintainability, etc. There were a few improvements,
but most changes were to reduce production costs, not improve the
product or make it easier to use or maintain. Having the nail gun jam
3 times immediately after unpacking is an ominous clue that it's going
to cause problems. Switching from a plastic magazine to a magnesium
magazine is an improved but also an indication that the original
plastic magazine was likely problematic. Yes, it's disappointing.

Have a good holiday.

What were you doing with two drills that lasted less than one year?
Were you trying to used them to power one of your bicycles and convert
it into an eBike? It's possible to do that, but the results are not
very good: <https://www.google.com/search?q=electric+drill+powered+bicycle&udm=2>
If it was less than 1 year, the drill was probably covered by a
warranty. Were you able to get you money back and buy something more appropriate?

Incidentally, I've been spending too much time watching YouTube videos
on repairing power tools: <https://www.youtube.com/@deandohertygreaser/videos>
If you're considering repairing the two drills you destroyed, watching
some of these videos should be useful. However, there's one problem.
The author is in Ireland and speaks with a very thick accent.
Sub-titles (captions) are a big help.

As is usual with you, you assume things you know nothing about. Just sitting around destroyed the batteries. They need to be discharged and charged frequently to live a normal life. Doing nothing at all but sitting in the cupboard destroyed the batteries
of thier own volition since actual use was infrequent.

You didn't explain how you killed the two "battery drills". Did you
kill the drills, the batteries, or was it two drills used together as
a battery of drills?[1]

Hint... one storage device is called a cell. Two or more cells are
called a battery. A cell phone has only a single LIPO cell and should
properly be called a "cell phone cell" and not a "cell phone battery".
Anyway, you're wrong (as usual) about how to manage cells and
batteries for long life. If you have any interest in rectifying your illusions, this is a good start.

"BU-808: How to Prolong Lithium-based Batteries" <https://batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries>
If you're interested in batteries and as a non-engineer, I recommend
his book:
"Batteries in a Portable World: a Handbook on Rechargeable Batteries
for Non-Engineers, Third Edition" <https://www.amazon.com/Batteries-Portable-World-Rechargeable-Non-Engineers/dp/0968211844>


[1] <https://en.wikipedia.org/wiki/Artillery_battery>
"Historically the term "battery" referred to a cluster of cannon in
action as a group, either in a temporary field position during a
battle or at the siege of a fortress or a city."
