are hammer drills worth it for concrete drilling?
« on: December 16, 2013, 06:18:26 AM »
i dont wanna buy one sense i dont have to drill into concrete that often , and i dont want another tool around. im thinking using just my regular drill and bit then occasionally hammering in a nail to go deeper and accurate

i hear with hammer drills you also dont always get a straight drive through the concrete wich could fuck up your anchor placement afterwords

I know nothing about hammer drills but having the right tool for the right job makes a load of difference. Mayne rent one when you have jobs that call for it?

Bosch hammer drill is the best to get.  Don't drill with a regular drill because it will fuck up the drill and the bit.

If you only have to drill holes 1/4 or less in diameter then you probably don`t need one. I have a cordless drill with a hammer setting on it that I use for setting little anchors and other light stuff.

 If you are going through poured walls you will need one, I have also used mine to weaken floors before I bust them open with the sledge.

 Hilti makes the best drills I have ever used for concrete.

Love my Dewalt hammer drill. I can set it from regular to hammer, so there's versatility for a guy like me who only sometimes needs the hammer function.

I went old school and bought the corded one...just got frustrated with batteries going and what not. Yes, it's more a pain. But I just do work around the house...I have enough extension cords to get me what I want. And call me crazy, but I feel the corded drills pick up more power.

Someone said about the 1/4" or smaller holes...I would agree. You might want to have a few more masonry bits at those sizes if you're not going to use a hammer drill. Just in case their wear out or snap. Without a hammer function, the tendency is to put a bit more pressure on the bit, and those little bits can snap on you. If you don't have a backup, you're back in your truck driving across town the hardware store.

But yes, it's honestly worth it. I would recommend getting a drill with dual settings if you don't drill concrete that much. When you need to put a lot of holes into concrete, do you want to spend 20 minutes (hammer), or 40 minutes (regular)?

Good post.


I use my impact driver when drilling concrete. Works pretty good, I've got the rigid one.

For deeper shit, I use a cheap 1/2" drill from Harbor freight. High RPM and does the job.

The batteries are pretty good in these but it's definitely for light duty shit. If you're drilling 1/2"+ I would go with this for $80

Buy a corded sds hammer drill.
The difference in unreal compared to a shitty normal drill which will take 5x longer and burn through 2 bits per day.
I have a dewalt one and when fitting conservatorys and windows it goes straight through the steel reinforcement in the pvc and the brick/block in seconds.
No swapping bits ect.

This. For brick a standard hammer drill is ok.  For concrete you want SDS.

If most of your work is underfoot, get a heavier one (probably will be cheaper too) and it'll double as a light duty demo hammer.  If you're doing commercial ceilings or going into overhead concrete a lot then it's worth spending money on a 36v battery Hilti or Bosch, but 99% chance a mains powered mid priced SDS will do what you want unless you are a commercial ceilings contractor.

Any drill will meander in concrete to some degree as the aggregate in the crete kicks the bit around.  If you're using C-track then who cares.  If timber then pre-drill the wood and use your bore to keep the line.  

Don't use a twist drill into masonry unless you want to look like a complete ass, dull the bit almost instantly, and swear like a sailor.  They are designed for drilling metal.  Metal cuts by being shaved away.  Masonry requires percussion to pulverize it.  The only exception I can think of is cold fired bricks like you would get in a historic structure or non fired blocks like adobe, but even then I would use a hammer bit without percussion.  Concrete, forget it.  You won't touch a high mpa concrete without percussion.

I've been using ramset chem anchor for the first time.  Amazing product if you're hanging off soft stuff.

What's the job, John?  Partition wall?

Buy a cheap hammer drill then return it when you're done (if you're only using it once)

A piece of wire or plastic zip tie inserted beside your fastener will keep it from moving, assuming you use the correct size bit relative to your fastener.

shizzo being of a more feminine nature has zero interest in a thread regarding tools.
On the other hand a thread on knitting, sewing, sucking cock ect ect would be right up his street.

Oh lawd above.  There's a lot of options anchoring into masonry but these aren't among them.  Don't do it, Brink.
