Hole size is not a detail
The sleeve has to fit the hole. Drill undersize and the sleeve will not seat; drill oversize and it will not seal, and an unsealed sleeve measures the room instead of the slab. Use the bit that matches the sleeve you are using — this is the 3/4 inch bit; for 12 mm sleeves use the 12 mm concrete drill bit.
Depth matters as much as diameter
In-situ testing standards specify the depth as a proportion of slab thickness. Fit the 3/4 inch stop collar so every hole is drilled to the same depth — judging it by eye across twenty test locations is how a survey becomes uncomparable.
