Use a Variable Speed Drill to drive the screws after the pilot hole has been drilled with a Hammer Drill
The proper depth of the pilot hole is dependent upon the material being fastened to the concrete.
Pilot holes for concrete screws should be at least 1/4 in. deeper than the screw will penetrate to allow a little extra space for dust accumulation from the hammer drilling process
Keep constant pressure on the screw and run the drill at slow to medium speed, Heavy-duty drills work best because they can maintain a steady slow speed
Drive the anchor in one steady and continuous motion until fully seated at the proper embedment.
Driving at high speeds may result in fastener failure
