I rented a rotary hammer drill from the lcl home depot. I bought my own bit vs renting that too, a SDS plus 7/8" bit. I initially used a 5/8" bit to start a couple holes thru the lift mount holes and then enlarging the holes. I was not happy doing that so I marked the floor and drilled with the correct size all the remaining holes. Marked the bit with tape for depth. Worked perfectly. Just drill with easy pressure and back out often to remove the material. It's a quick job.

Getting the holes perfectly vertical is the hardest part.

I cleaned the holes very carefully and repeatedly as I was using epoxy set anchors as well. Vacuuming with a small tube, brushing, very important to get those things dust free.

Buy an extra tube of epoxy to have on hand. You'll use more than you think. And clean those holes one more time just for chits and grins.
