Drilling in concrete or blocks/bricks

[Keel]

I just today bought some "better" drill bits for this, Bosch bulldog iirc
to help them last, is there anything to use as a "cutting oil" I'm guessing you wouldn't use oil ,but is there anything, or is just drilling dry, a-ok
mostly will be drilling into cin- blocks of basement wall to hang pegboard, and some other **** to get **** off the floor..

Attach them to a drill bearing an SDS receptacle and you can watch the dust fly. That said they drill concrete and masonry very well. Do not however, expect them to cut reinforcing steel.

Nah they last a real long time.
I like the hiltis, double cutting head makes for easier drilling.

When I drill overhead into the pan before the deck They still last a very long time.

The drill bits you are limited to (in the instructions!) are used dry. When you move up to a certain size (very very large) one would need water involved - but that requires a special core drill, with water system, etc.

What type of drill are you using. If you doing any sort of volume your going to want a real hammer drill and not a cordless with a hammer drilling option.

2x on the hilti's. Have tried every brand and off brand and they have performed the best for me.

In my limited experience, Hilte is the "Gold Standard" for drilling masonry.

"will be drilling into cin- blocks of basement wall to hang pegboard"
Drilling into Cinder block is a joke, no hard aggregate, brick a bit harder, pre 1900 brick, at lot harder; if you drilling 1" holes in cured concrete then you might consider water for lubrication. Last time I took down a crete wall I had to drill approx 125 1-1/8" holes with an SDS rig, basically no wear except for the sharpen edge of bit, Cinder block/brick will cause far less wear on a good bit . Cheap percussion drill will suffice for cinder block. Most you need to worry about is a decent dust mask.

As long as you're using a hammer drill, just rock on... it's great fun.

 

[Keel]

yes hammer drill, just figured I'd ask, as I'm a cheap sob and like to get as long as I can out of the bits..

If you're serious about doing some concrete drilling look at a rotary hammer, this is the sds-plus chuck that has been mentioned.

Let the drill do the work do not push hard

If you're going to use Tapcons, the holes are small so you shouldn't have any problem with any decent hammer drill. If you're going to use threaded anchors, the holes will be 1/2" or larger and using a hammer drill will be more challenging compared to a rotary hammer.

Drill into the blocks and not the mortar joins.

Make sure you get the dust out of the holes.

I use a BOSCH hammer drill and DeWalt Rock Carbide SDS Plus bits.

I had to drill 150+ 5/8" diameter holes 10" deep into concrete footers when I built my SteelMaster building. The concrete was 45 days old and it was like putting a hot knife thru butter. I bought a handful of bits thinking I would need them, but I only used up one bit.

When I installed some additional equipment a couple of years later in this shop thinking that the concrete would be really hard after a couple of years, these bits still cut thru like nothing.

Amazon has great prices on these.

As mentioned about a hundred times, if you're just mounting fasteners any regular hammer drill is fine. I doubt you'd ever use any type of fastener to mount pegboard that would require a $500 hilte to get through. If you're putting 3/4" pole hardware in a hardened concrete power pole that's a different story...

If you're drilling cinder blocks make sure you get something designed to work in them and go through the backside as gently as you can to avoid making a big void when it goes through. I'm pretty sure just a standard butterfly bolt much like you'd use in sheet-rock is all you need. Check around before you buy. For the brick just about any expanding anchor will work fine.

Those bits seem to last me forever. Drill away and don't worry about them.
