for anything more than 10 5/16" tapcons, the dewalt you got is mostly useless.

it uses a ramp-style hammer mechanism. so the harder you push, the better it works. but after 5 holes at 3/8", your arms will be jello. not to mention the noise-- imagine the card-in-bicycle-spokes, hardcore metal band edition, turned up to 3,000.

a real sds hammer drill has a small piece of round stock in it that is mechanically hammered into the bit to create the hammer action. most even have vibration damping internally. even the weakest of people can just hold the drill up, and it'll do the actual work. it's a lot quieter, and because of the different mechanism, far easier to work with all day.

i would highly recommend something like this. personally, i have a bosch, similar to this one.

and despite whatever the official max bit recommendation says, i've driven 2-1/2" coring bits with it with minimal issues.

edit-- if you don't have the inside track club, and want to use the discount, pm me.

That close to what I have as well.

Well, it was a fun day...

The breaker for the well pump at the garage has tripped a few times randomly.
Figured I better investigate.

This doesn't look so good, 20 years or so in a pretty miserable basement will do that to you.

And I think this might be the problem, just inside the pressure switch.

A trip to Slowes got a new pressure switch and also a heavy duty double pole switch rated 30 amps (the pump is 5 amps). Pressure switches cost more now, $38.
Slowes used to have Square D switches, now they have some generic... stuff.
We'll see how long it lasts.

The breaker is in the garage, the pressure switch is in the house about 150 feet away, there was no electric shut off in the house. I was there already it was easy to add the switch - the $18 super heavy duty premium switch I might mention.

My little corner of unhappiness for the afternoon/evening.

Job is all done except hooking it back up in the garage, another day.
