Check the location for the screw to ensure it is where you need it before drilling a hole. Avoid drilling unnecessary holes in the cement.
Install a masonry bit into the chuck at the end of the drill. Open the chuck by hand or with the key provided, depending on the type of chuck. Install a bit that is smaller than the screw. Tighten the chuck.
Drill a pilot hole in the cement in the location where you need to insert the screw. Hold the drill at a 90-degree angle to the surface of the cement to ensure you drill the hole straight. Apply a moderate amount of pressure as you guide the drill bit to the desired depth. Pull the bit out while the drill is still running to avoid fracturing the cement in and around the hole.
Remove the drill bit from the chuck at the end of the drill and install a driver bit into the chuck.
Insert a masonry screw into the hole through the item you are fastening to the cement. Insert the screw by hand to ensure it starts evenly in the hole.
Fasten the screw into the cement completely using the electric drill with the driver bit installed. Ensure that the screw is snug, but do not over-tighten the screw.
