dear brew cabiners
currently working on my garden, and my parking space where i park my truck has kerbs (street style) separating the lawn from the drive.
I wanted to put some lights into the kerbs, the small round ones.
Has anyone ever done this, and how did they drill them? will and SDS do the trick??

The 24mm led ones?
Ive got a opened set of LEDs and some old scrap kerbs at the yard I'll do a test in the morning drilling them, should be ok their very solid.
The set I've got are robus r3led5 ip68 5 lol what ever all that means. But there 3 LEDs in each fitting, says not to bury transformer, but itd be fine inna waterproof junction box

not sure, as i am going to go to the electrical wholesalers to see whats about.
can't see why and sds won't do it. Doesn't matter if the back of the kerb gets chipped as it won't be seen.

Be careful with the drill bit choice a lot of the larger bits drill an oval shaped hole I don't know why but they do. The hole from a 24mm bit could be 30mm at it's widest point and not completely covered by the flange.

Use a Hilti sds drill bit, newer type with the 4 cutting points. these things are like a hot knife going through butter and will leave a perfect sized hole or you can buy cheap core bits for a lot less than the hilti solid. light wise look for anything that is IP 67-68, 67 will be ok but you really want 68 along with fittings to suit. I`ve got stuffing glands and a new packet of copex (flexible plastic conduit) if you want it.

i always work holes up from 6,10,12,18mm etc etc
i find the bigger drills go askew if you try to drill them in 1 go

i was unsuccessful with a hilti te 56 and various hilti sds plus drill bits to drill a nice neat hole that the light covered, the kerb just blistered the front around the hole, maybe my selected weapon was a little aggressive doing a 24mm hole in about 40 seconds, tried on reduced hammer and going slow, tried starting at 12,16,20 then 24mm still got surface damage. pictures to follow.

te-56 giles, nothing like using a sledge hammer to tap in a drawing pin. :laugh:

thanks giles. these lights are pretty expensive, so i may put this on the back burner. more so now that i know that drilling isn't going to be easy!

What about a diamond core drill?I believe you can get them at 24mm dia,it should give a nice clean hole.
