In the interest of science, be interesting if you could include the number of
beers you have had prior to each email each day. I hypothesize that your
vocabulary and alcohol consumption have a certain correlation. Just a simple
number at the beginning or end. 7, 9, 18...
The high numbered emails would probably be worthy of an archive.

Rotary hammers, fucking beasts.
We were talking about our tapered bits. We have tons with one dull ring. 46
bucks for 20 holes adds up.

I must have never used a rotary hammer then, hammer drills seem to work just
fine for stone, masonry, etc.

Yeah, never use anything but a hammer drill on stone/concrete/etc.

What you want for the concrete is a rotary hammer. A little spendy and
the bit cost is astronomical, but they will bite through granite like it's
nothing in seconds. We use rotary hammers for rohn wall mount kits going into
brick, concrete, and stone. Have only tried the corded hitachi's, although
dewalt has a cordless one I've been keeping my eye on.

is what we've used.

We are trying different brands for 3/32 holes we need for door contacts

and oil helps but we eat them up. For concrete and cinder block walls Hilti
drill and bits have no problem.

My dad has always sharpened his own, so I tend to do the same.
In my experience, if used in wood they can be sharpened with little
issue. If you drill through metal, buy a new one.
It loses some of the hardness on the edge. It really needs to be
tempered again after sharpening.

We are paying $15-$25 for longer drill bits. When they start to
get dull, just wondering if anyone has had success sharpening them or do you
just buy new ones?
