Expert Verdict Reviewed by the SuperArbor Pro Desk

Silver & Deming bits are the standard answer for holes larger than a 1/2 in. chuck can hold, since the reduced shank lets one chuck drill a range of big diameters. Match the 9/16, 5/8 or 3/4 in. size to your anchor or fastener requirement and pilot appropriately for clean holes in thicker steel. Keep a sharp bit and steady pressure, and step up gradually through thick plate to avoid overloading the drill.

Secure the workpiece with a clamp before drilling, and wear eye protection; large-diameter bits can grab and twist the drill unexpectedly.

Pick up a DeWalt Silver & Deming black oxide bit in 9/16, 5/8 or 3/4 in. for your next large-diameter hole.
