hello
this old floor has tough concrete- i tried using a 3/16" carbide bit then 1/4 " concrete screws but i could hardly dent the concrete-i'm using a 12 volt drill. i am now going to try drilling with a 1/2 " carbide bit then hammering in lead anchors/ sleeves into which i will screw the flange down. i'm not too optimistic i will drill slowly and water the hole -is there any advice you can give that will help??
also if this does not work, how do i remove an area of this very hard concrete so i can repour drillable concrete? would a cold chisel do or sdo i need to i rent a small electric jack hammer?
whew!!!!!

Cool

Use an electric drill with a masonry bit. Drill holes large enough for expandable lead anchors or Tapcons.
Should do the trick.
Good Luck!

Rent a hammer drill. You will have your holes in seconds using new bits.

3 to go

hi
i used water with low speed and the 1/2 " bit did a good job-i have three anchors in but they seem loose-when i get the other three in i'll see if the screws expand the anchor enough-if not i hope i can move up a screw size.
thanx for all the help-i looked into prices for hammer drills and i'll be happy if i can get away with what i've got but i'm not home yet.-by the way i made a mistake with one of the holes but anchoring cement filled it securely so tonite when i get home i can drill next to it.
nothing **** the right tool for the right job but sometimes............
let you know if and when i am up and flushing.
appreciate all the help
pete

You should be able to rent one at any tool rental store.
