Re: Simultaneous Multiple Tool Melt Down

My preferred cordless tool line for a long time was Milwaukee.  Used
to be Makita 30 years ago but they kind of fell behind.  Day in day
out as a contractor I bought Milwaukee cordless.  When one of my
drills died, and new brushes didn't revive it, and then I got down to
just one good battery I gave up and went cheap.  I used the Harbor
Freight Bauer line.   Its not horrible, the tools are cheap, and the
bigger batteries are actually decent.  After my dad passed away I
found he had gone with DeWalt.  I gave all my Bauer tools to my son
and started using my dad's DeWalt stuff.  Well, not in that order.

I also found (with both Bauer and DeWalt) that for some tools the
smaller batteries are fine.  I figured they would be fine for
everything.  They just wouldn't run as long.  No.  That's not
true. Some tools just wouldn't run very well on the smaller batteries
that usually come with the "packages."  A couple come to
mind. Cordless angle grinder, chainsaw, hedge trimmer... Bauer or
DeWalt both kind of bogged out instantly with the small batteries and
produced respectably with 4AH or bigger batteries.

I just spent $700(+) dollars on four legit (not Amazon or eBay knock
offs) 8ah DeWalt batteries.  I figure after dropping real coin on
batteries I'll walk in the shop tomorrow and find melted pools of
yellow DeWalt plastic everywhere there used to be a DeWalt cordless
tool.

I use 4Ah 18V (that's "badge-engineered" to 20V in the USA) batteries in
the SDS-drill I use for drilling sockets in granite.
Seems to work very well.
About battery size and finding that not the most massive battery seems
necessary to get performance which seems absolutely fine.

Have previously asked on r.c.m. when looking to set up this capability.

Are DeWalt drill and battery.
Is DCH263.  Largest drill using "small tool" batteries (?).

Drill is best no pilot drill to 12mm into hard granite including elvan
(very hard fine-grained dykes where magma has infilled fissures in
previously solidified granite).  14mm there might be an advantage in
pilot-drilling - not less than 7mm because the drill over-powers
anything smaller and melts the tool - but not more than 8mm - seem to
want to pilot at half the final drill size.
Talking about carbide-tipped masonry drills.

4Ah does quite a lot of holes.
Working hard breaking rocks, get through 1~1/2 4Ah batteries in 3~1/2
hours.  That's both drilling sockets and using the feathers-and-wedge
sets to break-up boulders.

Locally the price for 18V DeWalt Li-ion batteries is GBP13 per Ah.
Had 4's but no 5's, so as price is pro-rata here, got another 4Ah.

Coming back to your point - the batteries seem just fine, and I let you
be the judge of that by describing the work they do.
