Should have bought a hammer drill
 
Hi;
I've had to drill several small (3/16 max) holes in brick, and has me wishing that when I bought my DeWalt variable speed AC powered drill that I had bought the hammer drill instead.
I was advised in one of these forums about drilling in masonry, but I didn't want to spend the extra $ at the time. It wasn't even that much...

I broke one smaller masonry bit (1/8 I think), but was able to continue using it with the shorter shank. All I was doing was drilling one new hole to put up a new (larger) mailbox.

So, next time I have to do some masonry drilling, I think I'll spring for a slower speed drill with the hammer feature. That way, I won't have two of the same basic tool.
So, when I do, what kind of drill bits to I have to buy? Is there a specification I need to look for to know that a drill bit can handle hammering?

Thanks

For real occasional use---get a cheap one---I have two throw away hammer drills set up for the two most common sizes that I drill----they were only $35 or $40 each---

A good Bosch or Hilti will cost you a lot--best to rent when you need a big boy.


Bit quality varies---Bosch bits are good---Vermont American are not---

I spent about two hours trying to drill a hole in concrete with a regular drill. Eventually I gave up and bought a hammer drill. It only took about 30 seconds with the correct tool. What most people don't realize is that a hammer drill does not cut the concrete but it actually chisels it.

I have some big boy tools in my equipmet trailer but for around the house use I have a whole set of Ryobi tools that work just fine.
One of the drills I have is one of these.

It can be used as a reguler drill or flick a switch and it's a hammer drill.
It also has two speeds.
It uses the cheapest masonery bits with just straight shafts.
Ryobi batterys also cost about 1/2 as much as any other brands. I've had them far outlast the Dewault batterys I used to use.

I think I bought the DeWalt variable speed AC powered drill because I wanted just that; an AC powered variable speed drill. It's what I use 90% of the time. But I will get a hammer drill before I try anymore masonry drilling. I would still go corded though.
