You won't be able to drive _dozens_ of Tapcon screws with any type of
battery drill. Depending on the screw length and size and the material
hardness, you might be able to drive only one or two, though I would
expect at least 10 to be typical.
Steve, I have already used a Hitachi mini impact to drive a couple dozen
tapcons and it had plenty of battery.It was effortless. I just did not
notice what size it was. I had 3/16 predrilled holes. Tony
That's impressive. I have the same drill driver, but I've never used it
for Tapcons. My batteries, less than a year old, are good for about 50
3.5" deck screws into treated pine. I would have guessed that Tapcons
were much tougher to drive into concrete. My big corded Bosch hammer
drill really lugs down running Tapcons into limestone, so I'm surprised
the Hitachi does so well. I'll have to try the little guy next time.

The blue paint on the screws is a glue that melts from the friction of
driving the screw, then sets to hold the screw in place. On the big
Tapcons, technique is important. If I don't drive the screw all the way
home without slowing down, the glue will grab hold when I'm only partly
done, and then I twist the head off the screw. That happens easily when
I put big screws into deep holes. Oh, and I _do_ use the correct Tapcon
bits to go with the screws. They're an odd size.
Hey Steve, I bought an 18v at HomeDespot. I didn't know about the bit
thing and bought a standard sds 3/16. If it doesn't work I will post
about it. I am screwing down 2x4 to hold the bottom of a 7' wall in
place. I put them on 2' cntrs. The bit that comes with tapcons is not an
sds bit so I don't know how "I" would use it anyway. Thanks for the
comments. TonyG pt.townsend,wa.
So, you are securing the 2x4 sill plates to a concrete floor.
I installed 2x4 sill plates all around the perimeter of my basement
using a Remington hand held powder actuated fastener tool.
Much faster and simpler than all that drilling, cleaning out of the
holes, and the screw driving.
Load the special nail and a special .22 caliber load, place the fastener
on the plate, and hit it with a hammer. I used the cheaper hammer
operated fastener rather than the trigger operated one since I thought I
would never have to use one again, so I saved myself about $50 for the
hammer one, which is only about $25 or so. It takes as much time to
drive a nail as you need to load it, hammer it, and move to the next
bay. Besides, you don't have to vacuum up a whole lot of concrete dust
afterwards, and it's kinda fun shooting things in the house. I secured
200' of sill plates in about 15 minutes.
But, you're probably set on the tapcons and bought the hammer drill and
all, so carry on. Someone else may use this info for a similar job,

I doubt that you will be reusing the tapcons 2 or 3 times. Breaking a
tapcon screw while installing is pretty common. You'll be lucky if you
can get them out without snapping off a few, much less trying to reuse them.
No, actually they come out nice from a 3/16 hole. I have taken out over
30 of them on my last job and never broke a one. I don't know if they
will go in again but they came out fine. They weren't mine so I left
them where they fell. T
To install tapcons, first you predrill a hole..then you drive 'em in. I ve
done several with my 18V Ryobi P220 Hammerdrill. I'd expect to be able to
do at least a couple of dozen (3/16 - 1/4") on a charge..these batts last a
LONG time on HD drilling compared to my DeWalt 12V.
