Drill bit: Brick

Hey gang..
I was wondering, anyone have a good suggestion for a drill bit that'll cut through a brick? I'm trying to mount my flag pole base to the side of the house. I have two "concrete" drill bits and they both suck........ Don't cut through the brick worth a damn........  Is there a difference between a concrete versus brick bit?

Thanks.....

I'm assuming that you are not using a hammer drill. Get one, with bits that are appropriate for it. http://www.harborfreight.com/power-tools/hammer-drills.html  I have a Bosch that puts holes in concrete and brick in no time.

yup need a hammer drill and bit kinda like an impact but different.
Restoring a charger is like a saying I heard along time ago "I never said it would be easy, I only said it would be worth it".... Jesus I wish I could remember who said that...

I just use the masonry bit in my regular drill motor...cuts through just fine

should use the hammer drill when cutting in stone and concrete, might blow apart the brick though.

I think I would try a regular masonry bit first, I would hate for you to blow out the brick on the side of your house with a hammer drill!!
Sold my Charger unfortunately....never got it finished.

if the brick is already on the wall then you should drill the mounting hole in the mortar not the brick

Uh, not what I'd do. The mortar will not sustain long term load weight and the holes will blow out in time or even straight away when the dynabolt or terrier is tightened up. Depending what type of brick or concrete breize block, aim for the centre of the block and the the internal rib for max retention. Rotary drills are ok but pneumatic hammer are the way to go. I mount heavy a/c units - they have to stay attached  ;) I have a Hilti 550w with a quick release head for 3 jaw and concrete bit, great drill

Thanks all.... All I'm trying to do is mount the base for my American Flag and the place I want it is on the exterior wall near a light ( it is customary that an American Flag outside in the dark should be lit )... Really didn't want to go out and buy an expensive hammer or pneumatic drill for such a simple job......  :brickwall:

Troy in years of construction I found a HUGE difference in the quality of bits and blades for any drilling/cutting task. You may just have some crappy bits, try high end (Spelled: "more expensive" bits.) and keep the receipt in case they don't work well.  :2thumbs:
