What sort of drill will i need to drill into my concrete driveway (has the stones in too) and what drill bit is going to be best?!

Want to fit one of those security posts into the ground!!

How big is the post ? I would use a stone cutter to cut through the concrete which will probable be approximately 4 - 6 inches deep. You will then hit gravel and earth. Dig the rest out by hand and it should fit just nicely. Stone cutters are easy to hire from most hire shops.

a masonry bit?

what type of post are you fitting?

i fitted 2 in my drive but they had to be buried in about 1m deep.

use a styl saw to cut the square out of the concrete then dig the rest by hand.

You have to get the post right deep in the ground ,just drilling holes for m8 ,m10 rawbolts they can be pulled out .

hire a big ass hilti gun with a masonry bit and it will take about 10 minutes.

same here, was a right bastard, used a metal pole to break it all up then dig it out after getting through the concrete..

edited to say mine is the sort that sinks into the ground so had to go down about 1 metre..

Yea was thinkin SDS but wondered if an 18V cordless makita hammer drill would have the "minerals" to do it?! prob not lol

a cordless simply won't do the trick - it'd be fine till you hit a stone, then you'll be let down by the puny hammer action.

Mains SDS is the way to go. Preferably a titanium tip bit.

about 200gm of c4 sunk into a drilled pilot hole should do the trick.........

my battery bosch pro would go thru anything, gas mains the lot wouldpiss thru your drinbve, now (for a different co) i have a ryobi, not near as good but would still do it
drill corners then along the sides and it'll come out nice

18v cordless would be fine up to about 10mm if you needed bigger you would be better off using a mains sds as the hammer action on the battery one will run out of puff as said, depends what sort of fixings your using? for instance a proper m8 shield anchor needs a 14mm diameter hole drilled. Go mains if you can, defo easier, I struggle like fook sometimes with my battery one because I can't be arsed to go to the van and get the hilti

Problem with these posts is that you provide the leverage to pull it over simply by it being a pole you would be better off in the long run fitting a proper one thats secured in concrete or similar into the ground.
